Description

Invention of technology that increases the braking power of studless tires

Conventional studless tires include studless tires with braking such as foam rubber tires, but the braking force on ice and snow surfaces is still not perfect

Even if you put linen etc. on the surface of ice and snow that is slippery and has water on the surface near 0 ° C, it will be very hard to slip even if you press the linen. This means that the linen absorbs moisture on the surface and is very slippery. Because there is this principle and using this, creating a lot of minimal space in the studless tire tread part,

Means for solving the problem

Studless tire rubber is made into a thin fiber, and it is entangled to create a tread part of the studless tire to absorb moisture on the ice and snow surface to produce a studless tire with high braking power

Studless tire rubber is made into a thin fiber, and it is entangled with finely woven fibers that can withstand high temperatures such as hemp and aramid, while the thin fibers of studless tire rubber are entangled [space] Studless tire rubber that is finely interwoven with fine fibers such as hemp, etc., and the thin fibers of studless tire rubber are disturbed by fine interlaced fibers such as hemp, even when high temperature and high pressure are applied The fibers do not adhere to each other, and the uninterrupted studless tire rubber-like thin fibers are bonded to each other in a cross shape, so that finely chopped fibers such as hemp become spaces. Studless tires with high braking power are produced by increasing the moisture absorption on ice and snow surfaces in many spaces.

Studless tire rubber compounded rubber is applied to linen, hemp yarn and hemp fiber, or mixed together to produce a studless tire tread part, and the surface of the tread part is shaved to expose the linen and hemp thread. Studless tires with improved braking power by absorbing moisture on ice and snow.

Add a small amount of trichloromethane (chloroform) or carbon tetrachloride (tetrachloromethane), which has a lower boiling point than ice, to the compounded rubber, mix well, and add the compounded rubber containing trichloromethane or carbon tetrachloride in the form of mist or colloid to the carcass. A large amount of minimal space is created in the studless tire tread by winding and attaching to a mold plater and inflating with high-temperature and high-pressure steam to evaporate the trichloromethane and carbon tetrachloride contained in the form of mist and colloid. Studless tires with high braking power on ice and snow surfaces by absorbing moisture on ice and snow surfaces.

The invention's effect

This technical invention creates a studless tire with high braking force by tying thin fibrous rubbers together to create a lot of space in the studless tire tread part and increasing the moisture absorption rate of the studless tire on the snow and ice surface. Moisture absorption on ice and snow surfaces from exposed fabrics and threads such as hemp and aramid by manufacturing and manufacturing studless tires by applying compounded rubber using fiber fabric and threads such as hemp and aramid The studless tire is made by increasing the braking force on the snow and ice surface by the friction of the exposed cloth and thread such as hemp and aramid.
Add a little water, trichloromethane and carbon tetrachloride to the compounded rubber, mix well, wrap the compounded rubber containing water, trichloromethane and carbon tetrachloride in the form of mist or colloid around the carcass and add gold to the vulcanizer. Attached to a mold ladder and inflated with high-temperature and high-pressure steam to evaporate mist and colloidal moisture, trichloromethane, and carbon tetrachloride to create a lot of minimal space in the studless tire tread part on the ice and snow surface Studless tires with a high moisture absorption rate and high braking power on ice and snow.

A rubber material for studless tires that has frictional force, low rolling resistance, good low temperature characteristics, and good wear resistance, such as S-SBR, HBR, S-SBR and HBR. Rubber compounded with carbon, sulfur and various fillers and mixed well.

The above compound rubber is melted at a high pressure at a high pressure [Fig. 1]. As shown in Fig. 1, 2 is a thin fiber-like [10 µm to 1 µm] jetted melted rubber from a jagged hole. 3) to produce a thin fibrous rubber by sending hot air as in [3] [Jet spinning method] or by blowing the molten compounded rubber into a high voltage of 2000 to 4000 V to obtain a thin fibrous rubber. [Electrospinning method] to produce quality

As shown in [Fig. 1], hot air as shown in 3 from the two sides where two devices are jetted into a thin fibrous rubber at a high pressure at a temperature at which the compounded rubber can be melted are arranged side by side. To make the rubber of the tread part of the studless tire by tangling together the thin fibrous rubbers that were poured out at the same time as 4

Hot air is too hot and thin fibrous rubber becomes sticky and sticky, it is not good, thin fibrous rubber is about half dry so it does not stick so much, it is best to get tangled well with hot air When the thin fibrous rubbers cross each other, it is best to bond them a little and adjust the temperature of hot air and hot wind so that it will be in such a state.

In order to achieve such a state, even if a thin dry fibrous rubber material is made by sending a hot air that adjusts the temperature of the hot air, hot wind, etc. to make it completely dry, it is entangled with the wind [Fig. It is made into a plate-like shape and wrapped around the carcass of the drum in the studless tire manufacturing process and attached to the mold platter of the vulcanizer, and it is inflated with high-temperature, high-pressure steam and molded into a studless tire. The cross-shaped place where the thin fibrous rubbers are entangled with each other at high pressure makes a tread part that is bonded, and the thin fibrous rubbers are entangled with each other and are directly high on the fluffy plate-like object Even if pressure is applied and molded into the shape of the tread part of a studless tire, the thin fibrous rubber is entangled with each other and the cross-shaped part is bonded by pressure heat only to the carcass in the tire manufacturing process Winding Attach the drum to the mold platter of the vulcanizer, inflate with high-temperature and high-pressure steam and apply pressure directly to the carcass in the shape of the tire, and bond the molded tread part with adhesive to make the entire studless tire Manufacture

[0009] In FIG. 1, 2, a fine hole with a jagged shape that pours out the thin fibrous rubber is thin, and when the fiber is poured out, the fiber is jagged, and the thin fibrous rubber is entangled with each other. If this happens, it will be easier to increase the space and absorb the moisture on the snow.

The jagged micro hole can be formed by hot-melting a hole of about 10 μm, but a laser hole is used to create a micro hole, as shown in [Figure 3]. 4) As shown in 5 above, it is made by penetrating the shape of a hole in a ceramic or iron plate, etc. (this can be done manually). Concentrate the light with a lens or a 9-sided mirror, and place the knurled hole in the shape of Fig. 3 in the ceramic or iron plate of 5 above where it does not concentrate so much. A jagged hole that can be made to be less than 1 μm in the material of the portion where the laser light is concentrated at high density and the fine fibrous rubber is poured out through the laser beam through the hole shaped like Mold 10

Studless tire tread rubber material made by entanglement of thin fibers made by 0008, 0009, 0010 is made into a thick plate like [Fig. 2]

The thick plate is wound around 11 carcass in the process of manufacturing a studless tire (FIG. 5) to make 12 raw covers, and 13 is a thin fiber rubber plate made into a carcass. In the state of winding, if pressure is applied, wind thickly so that it is about the same as the thickness of the tread part of the studless tire

The raw cover is attached to the mold as shown in FIG. 6 on the mold of the vulcanizer and inflated with high-temperature and high-pressure steam and molded into the shape of a studless tire as shown in FIG.

It is important to harden the thin plate-like rubber material wrapped around the carcass of the studless tire manufacturing process with a pressure that is pushed by hand. In state

If it is hardened with high strong pressure, the thin delicate rubber made of 0008, 0009, and 0010 has elasticity, so it is difficult to adjust the tire mold even if it is inflated with high temperature and high pressure steam. Because

A thin, thin fiber that is entangled and wrapped around a carcass, attached to a pradder, inflated with high-temperature, high-pressure steam, and made into a tire in the form of a vulcanizer mold. The entangled rubber plate has room to deform even when it is wound around the carcass, and it is adjusted to the shape of the tread of a studless tire with high-temperature and high-pressure steam.

In that case, when it is wound around the carcass, it is wound around the carcass in a thick plate that is slightly stiff and stiff enough to be pressed with a thin fibrous rubber entangled hand. Thickly wrap around the center as shown in [Fig. 5] 13 and attach it to the mold plater of the vulcanizer, and inflate it with high-temperature and high-pressure steam.

When the swelled, the thin fiber rubber entangled plate-like tread part at the center of the width of the carcass is deformed as shown in 15 of [FIG. 8], and the thin fiber rubber at the center part of the carcass is deformed. The center part of the carcass tread part of the carcass is thinned from the center part of the car tread part of the carcass tread part. When a thin fiber rubber-like tangled fluffy plate is wound around the carcass, it is thickly wound so that it rises to the entire center of the carcass width.

A thin fibrous rubber entangled fluffy plate is wrapped around the carcass thick and attached to the mold platter of the vulcanizer, then inflated with high-temperature and high-pressure steam, and the tire mold is prepared as a tire The tread of the studless tire is molded to a hardness and thickness suitable for practical use at high temperature and high pressure.

It is important to adjust the thickness and the temperature and pressure of the high-temperature and high-pressure steam, so that the thin fiber rubber-like entangled fluffy plate is wrapped around the carcass.

When many thin and entangled plates are wound around the carcass, the first plate in contact with the carcass may be attached with adhesive on the entire surface. If the adhesive is applied to the carcass, do not get wet on the entire surface of the adhesive, and apply the adhesive to the carcass from the point where the adhesive is applied. Where the tread part is entangled in a thin fiber, it absorbs less moisture and does not pass through it, resulting in poor moisture absorption.

Groove the tread part of the studless tire that has been formed into a tire mold with the mold of the vulcanizer to make a grip on the snow and ice surface and add siding finely to increase flexibility and more on the snow and ice surface Create a tread part of a studless tire that facilitates moisture absorption [Fig. 9] 16 is a groove, 17 is a siding

The tread part made of thin fibrous rubber and entangled has a lot of space, which absorbs moisture on the snow and ice surface, and the absorbed moisture is discharged from the side of the groove dug in the tread part The water is absorbed well on the ice and snow surface and the braking force on the ice and snow surface is good [Fig. 9].

The rubber material entangled in the fine fiber shape made as the tread part of the studless tire made of 0009, 0010, 0011, 0015 is entangled when the tire is trimmed with high temperature, high pressure steam in the mold of the vulcanizer In some cases, the thin fibrous rubbers that are put together generally adhere to each other and there is no space between the thin fibrous materials, making it difficult to absorb moisture.

In order to solve this problem, a fiber (about 1mm to 1μm) with fine wear-resistant fibers that can withstand high temperatures such as hemp and aramid between the thin fibrous rubbers entangled [Fig. 15] Put it in like 25 and entangle it

Folded plate-like material hardened with the force of pushing it by hand is wrapped around a carcass of a drum that has been manufactured over the course of a studless tire as shown in [Fig. 15]. It is attached to the tire and inflated with high-temperature, high-pressure steam to prepare a studless tire.

Fine fiber rubber that can withstand high temperatures such as hemp enters between the entangled thin fibrous rubbers that are made as rubber of the tread part of studless tires, so that the thin fibrous rubber even at high temperatures and pressures. The quality is obstructed by finely chopped fibers such as hemp and thin fibrous rubbers do not adhere to each other, and there is a space between them, and thin fibrous rubber that is not disturbed by finely knitted fibers such as hemp A large number of spaces containing finely knitted fibers such as hemp between each other, where the space is bonded and hindered by hemp, etc., and the thin fibrous rubbers bonded together without being hindered by hemp Made

It is easy to absorb moisture on the snow and ice surface, and it is easy to brake the studless tire on the snow and snow surface, etc.There is no space where finely knitted fibers such as hemp are infiltrated. The kneaded fibers activate the surface tension of the water to make it easier to absorb more moisture, and the absorbed moisture is also discharged from the side of the groove dug in the tread part, so moisture absorption Better braking on ice and snow.

7. Treads of the studless tires according to claims 5 and 6 are entangled with a finely chopped fiber having wear resistance capable of withstanding high temperatures such as hemp while the thin rubbery fibers are entangled with each other. How to make a studless tire tread

Two devices that produce thin fibrous rubber by extruding and pouring from the jagged small holes lined up at high pressures at a high temperature at the melted temperature of the compounded rubber for studless tires described in 0010 [Fig. 1] The thin fibrous rubbers that are poured out in two units while sprinkling from above the wear-resistant fibers that can withstand high temperatures such as finely lined hemp 18 as shown in FIG. Sending hot air from both sides to entangle the thin fibrous rubbers so that the finely chopped fibers that can withstand high temperatures such as hemp between the stands are tangled toward the scattering direction At the same time, it is made by tangling together finely chopped fibers that can withstand high temperatures such as hemp that is scattered from above.

This is because of the wear-resistant finely chopped fibers that can withstand high temperatures such as hemp and the thin fibrous rubber that flies while cutting to a certain length by sending hot air to the thin fibrous rubber that is pouring finely If the specific gravity is not the same, the hemp may be blown above the thin fibrous rubber or the thin fibrous rubber may be blown above the hemp etc.

Viscosity in preparation for cutting the length of thin fibrous rubber with the strength of hot air or preparation of fine fibrous rubber, such as high melting temperature of rubber compound Preparation of thinness by stretching out from the jagged small hole of
The speed and elongation of pouring through a number of jagged small holes in a gusset that applies high pressure to the melted compounded rubber By adjusting the length and fineness, the finely knitted fibers that can withstand high-temperature wear such as hemp when hot air is sent and the fine fibrous rubber are entangled with each other evenly.

Or, as a method of entwining variously and evenly, hot air or cold air as indicated by 20 in FIG. 11 from both sides of the two units that are poured out as thin fibrous rubber. Along with the fine fiber that can withstand high temperature and wear, such as hemp, is blown apart and tangled with each other along with the thin fibrous rubber that is poured out.

Or two high-temperature wears such as hemp along with hot or cold air as shown in 20 in FIG. The finely chopped fibers that can withstand the spray are blown apart and entangled with each other evenly in a thin fibrous rubber like 22.

Blow away the finely kneaded fibers that can withstand high temperatures and wear, such as hemp, along with hot or cold air from slightly below in the direction between the two thin fibrous rubbers that are being poured out. Even if the thin fibrous rubber that is poured out with hemp etc. does not have so much specific gravity, hemp etc. flies from the diagonally lower side, and the thin fibrous rubber that is entangled while pouring out and falling down And hot air or cold air blown away and finely chopped fibers that can withstand high temperatures and wear, such as hemp, mix well together and intertwined, and the entangled objects fall by weight

Or, with the thin fibrous rubber being poured out in the direction between the two, as shown at 20 in [Fig. 13], it can withstand both hot air and cold air from the slightly lower side together to withstand high temperatures such as hemp. In addition to the device that blows away the fine abrasion-resistant fibers that are blown away, 20 hot and cold winds are sent to separate the fine fibrous rubber and 20 fibers of finely divided fibers that can withstand high temperatures such as hemp. Tangle like 23 to get into each other well together

In this case, the place where the fine fiber rubber that is resistant to high temperatures, such as hemp, is blown away with a device that blows away the fiber is not the place where the thin fibrous rubber ends with the hot or cold air, but the thin fibrous rubber. Blows onto the place where the qualities are about to begin to entangle with each other, so that finely chopped fibers that can withstand high temperatures such as hemp can be entangled well together

ゴム質と麻などの高温に耐えられる細かくきざんだ繊維とが互い互いにうまくよく入り混じり合って絡んだ２４のように造る、Or, the thin fibrous rubber that is poured out from both sides, as shown in [Fig. 14], both hot air and cold air from both sides and a little diagonally below each side In addition to a device that blows finely chopped fibers that can withstand high temperatures and wear, as in 3, send both hot air and cold air as in 3, and even between 2 units

The rubbery and finely chopped fibers that can withstand high temperatures such as hemp, etc. are mixed well together and made like a tangled 24,

The length of finely chopped fibers that can withstand high temperatures such as the strength of hot air and the temperature, the high temperature at which the compounded rubber is melted, the high pressure, and hemp Made of finely chopped fibers that can withstand high temperatures such as hemp and fine fibrous rubbers that are entangled well and evenly with each other by adjusting the sheath, fineness, fineness, etc.

Fine, abrasion-resistant fibers that can withstand high temperatures such as hemp while thin fibrous rubber is entangled like 0034, 0035, 0036, 0037, 0038, 0039, 0040, 0041, 0042 If you want to make a plate-like thing by mixing and mixing, even if you do not send hot air, send it with just wind or cold air, and the thin fibrous rubbers are intertwined in a completely dry state, while hemp etc. The finely chopped fibers that can withstand the high temperatures of the water are mixed well, mixed and entangled into a plate shape, and then wrapped around the carcass and attached to the mold ladder of the vulcanizer with high-temperature and high-pressure steam. Even if it is inflated, fine fiber rubber that can withstand high temperatures such as hemp enters between the entangled thin fiber rubbers. A thin fibrous rubber that does not wear and is not obstructed by fibers such as hemp adheres to each other, and a lot of finely knitted fibers that can withstand high temperatures such as hemp are in between. It has a good braking force on ice and snow surfaces that absorb moisture of water, and 0040, 0041, 0042, a device that blows finely chopped fibers that can withstand high temperatures such as hemp from both sides together with hot air or cold air, and hot air from both sides It is because it is written in that sense that I write that it sends cold air,

Stitchless tire treads made by 0029-0043 are grooved as shown in 26 of [Fig. Moisture absorbed more than flexibility and moisture absorption is also drained from the side of the trench, and moisture absorption is further increased, making braking on ice and snow surfaces very good ,

The manufacturing method according to claim 7 is made of 0015, 0030, and claims 5 and 6, and the plate-like material entangled with the fine fiber of the studless tire rubber made in 0015 and claims 2 and 4. Studless tire rubber is a carcass in the tire manufacturing process that is made by interlacing thin rubber fibers with a wear-resistant fine kneaded fiber that can withstand high temperatures such as hemp. When it is wound and attached to a mold platter of a vulcanizer and inflated with high-temperature and high-pressure steam to form a tire, fine fibers adhere to each other more than necessary at high temperature and high pressure, resulting in a high space ratio. As a manufacture to prevent the construction of a studless tire tread that does not absorb much moisture

0015, Claims 2 and 4 made of a thin fibrous rubber material entangled with each other, and 0029, 0030 and Claims 5 and 6 made of a thin fibrous rubber material entangled with each other. A piece of fluffy plate that is entangled with finely chopped fibers that can withstand high temperatures, such as hemp, etc. The tread part of the studless tire is manufactured by applying a pressure so that only the part adheres and applying the pressure heat.

In that case, it was made into a fluffy plate with a fluffy plate made of fine fibrous rubber and tangled fibers with wear resistance that can withstand high temperatures such as hemp. The thickness of the fluffy plate-shaped object was also made into a fluffy plate shape with the same thickness as the thickness of the tread part of the tire by applying pressure, and manufactured by applying pressure To produce the tread part of the studless tire by applying pressure so that the tread part of the tire is molded according to the size, shape and curve of the tire,

A carcass that is being manufactured during tire production was inflated with high-temperature, high-pressure steam using a mold platter of a special vulcanizer. A tireless tread portion 29 is manufactured to a part or a portion so that the built tread portion 29 is easily applied, and a studless tire is manufactured by securely adhering to the carcass with an adhesive like the tire tread portion 29.

Ditch a groove in the tread to make a grip on the snow and ice surface, and add siding to improve flexibility and more moisture absorption on the snow and ice surface. It is also discharged from the side and better absorbs more moisture on the ice and snow surface, improving the braking force on the ice and snow surface,

質に細かい霧状に附着させる、When manufacturing Claims 2, 4, 5, 6, 7, 0008-0050.
If thin fibrous rubbers are difficult to adhere to each other, send hot air from both sides of the two high-temperature, high-pressure devices that pour into thin fibrous rubbers at the same temperature to melt the compound rubber for studless tires. When a thin fibrous rubber is made and the thin fibrous rubber is entangled with each other, the viscosity is reduced to 30 with hot air from both sides of 3 in FIG.

Attached in a fine mist to the quality,

In this case, when the liquid adhesive is sprayed from the device in a mist form by a rubber tube that sends air pressure to the device that makes the liquid adhesive mist, the thin fibrous rubber together with the hot air is crossed together In order not to bond the part where it is a little glued and crossed, the position where the liquid adhesive is sprayed in the form of a mist to dry so as not to be glued is more than the place where the thin fibrous rubber is entangled, Use a liquid adhesive that is better than the location where hot air is blown, the viscosity of the adhesive is strong, weak, or the evaporation of the petroleum-based material contained in the adhesive, or the temperature of the hot air Prepare so that the adhesive does not dry out too quickly or slows down drying, etc.

The same applies when tangling finely chopped fibers that can withstand high temperatures such as hemp, etc. As shown in Fig. 19, wear-resistant finely chopped fibers that can withstand high temperatures such as hemp and hot air like 20 At the same time as spraying (spraying), a low-viscosity liquid adhesive such as 30 is sprayed to disperse finely chopped fibers such as hemp from the top as shown in 18, and the thin fibrous rubber becomes cross-like Where wear-resistant finely chopped fibers that can withstand high temperatures, such as hemp, are slightly crossed or in contact with each other, and thin fibrous rubber is not crossed or in contact If the finely chopped fibers that can withstand high temperatures, such as hemp and hemp, are not cross-shaped or in contact with each other, the adhesive should not be dried and adhered to it. As described above, the temperature of the hot air that blows away finely chopped fibers that can withstand the hot air is adjusted, the location of the location to blow off, the amount of finely chopped fibers such as hemp, and the strength of the hot air are also adjusted. Attaching a suitable adhesive

Even if a thin fibrous rubber material that is completely dry by sending hot air is attached, it can be attached to the mold plater of the vulcanizer and inflated with high-temperature and high-pressure steam to produce studless tires. Adhere the cross-like place between the thin fibrous rubbers and the parts that are in contact,
Even if a tread part of a studless tire is produced by applying high pressure to a thin fibrous rubber-like tangled and fluffy plate-like material, it becomes a cross shape in which fine fibrous rubber is entangled with pressure heat Where it is and where it is in contact,

The manufacturing method according to claim 9 is made by laying a yarn with a wear-resistant fiber that can withstand high temperatures, such as hemp and aramid, and woven the fabric with it. (It may be a fabric woven with fibers such as hemp instead of yarn, but we will use a fabric woven as much as possible.)

The hemp or the like cloth is cut into the same width as the tread portion of the studless tire as shown in 31 of FIG. 20, and the length of the tread portion in the state where the studless tire is cut off as shown in 32. Cut a little longer than the length, and cut the middle part of the fabric such as hemp cut to the same width as the tread part, and cut it up a little wider like 33

As shown in the left side of [Fig. 21], [Both sides of both sides of linen etc.] compound rubber blended with carbon, sulfur, various fillers, etc., well mixed with rubber for studless tires on both sides of the fabric such as hemp Applying and wrinkling the center of the linen as shown in the right figure of [Fig. 21] to make the studless tire the same length as the tread in the state of the ring, As shown in [Fig.22], several pieces of cloth such as hemp are layered together to form a plate.

It is wound around the carcass of a drum that is producing studless tires (as in [Fig. 23] 36), and the plate-shaped central portion that is wound around the carcass is raised.

In the raised part of the center part of the cloth such as hemp where the compounded rubber is applied on both sides, there is a wrinkled state as shown in 37 of [Fig.

Attach it to the mold platter of the vulcanizer and inflate it with high-temperature and high-pressure steam to form a studless tire as shown in [Fig. 24].

At this time, when it is molded into a studless tire at high temperature and high pressure, the material made by applying compounded rubber to a cloth such as hemp and wrapped around the carcass is inflated at high temperature and high pressure as shown in 38 in FIG. When formed into a tread with an arc shape

The wrinkled part of compound rubber and linen moved from the center of the plate-like bulge to both ends, as shown in 39 in [FIG.

If a cloth such as linen is cut into a straight width without the center part being raised and compounded rubber is applied to both sides and the wrinkles are overlapped on the center part to make a plate shape, then first from a plate shape such as linen cloth Apply compounded rubber on both sides of the narrow linen and wrap it around the carcass as shown in [Fig. 25] 40, and put the compounded rubber diagonally on the side as shown in 41. When a sheet of overlapping sheets is wrapped up, a combination of a narrow hemp or other cloth that has been wrapped around the carcass with a compound rubber applied to it and a hemp or other cloth that is wrapped around it. Apply the compound rubber and make a gap between the stacked plates, and raise the center of the carcass a little

On top of that, cloth such as hemp is cut into a straight line with the same width as the tread part, compounded rubber is applied on both sides, and wrinkles are placed on the center part to make a plate shape. [Fig. 26] Winding around the carcass as shown in FIG.

Adjust the thickness of the compounded rubber on both sides of the fabric such as hemp and adjust the density of the fabric such as hemp in the tread, the density, hardness and strength of the rubber when molded into studless tires.

The tread part of the studless tire that has been removed from the mold of the vulcanizer has changed from compounded rubber to elastic rubber, so the thin elastic rubber on the surface of the tread part is scraped off to expose linen etc. on the surface ,

To scrape off, water or heavy liquid is mixed with steel powder, etc., and sprayed onto the tread surface of the studless tire, and the elastic rubber on the tread surface is scraped off to expose the linen to the surface.

Since the steel powder enters the rubber of the tread part, the scraping method to scrape with a rotating file or the like can be scraped with a rotating file, or it can be scraped with various methods. The shavings etc. are flushed with water and dropped down by spraying, and the shavings etc. are dropped down by blowing a good wind.

A groove is dug as shown at 43 in FIG. 27 in the tread portion after shaving and a grip is applied on the snow and ice surface, and siding is added as shown in 44 to improve flexibility on the ice and snow surface. Improves moisture absorption and provides good braking on ice and snow surfaces. Moisture absorbed from ice and snow surfaces from linen exposed on the surface of the tread, etc. It is also discharged from linen and so on, so it absorbs more moisture and has better braking power on ice and snow.

Hemp and other fabrics may be dyed black or other colors that are the same as the studless tire color so that moisture absorption does not decrease.

The manufacturing method according to claim 10 is a method in which an abrasion-resistant fiber that can withstand high temperatures such as hemp and aramid is used as a yarn and is woven into linen [fiber such as hemp and amylad rather than twisted yarn] (It may be woven in linen as it is, but it is better to absorb the moisture if it is twisted to make a thread.)
You can also dye the same color as the studless tire, such as black, or the color that is not the same as the studless tire so that the moisture absorption of the hemp and aramid does not decrease.

Cut the linen, etc., slightly longer than the length of the tread with the studless tires cut off as shown in [Fig. 28] 45 [this is to make the center part slightly wrinkled. Length of
The length of 46 is longer than the round of the outermost rotating circle on the tread surface of the studless tire size, and the length is the height of the tread when the studless tire is rounded. As shown in [Fig. 36], it has a length that is folded several times in the width and folded into an accordion shape into a plate shape.

[Fig. 29] is a side view of cloth such as hemp on both sides, and rubber blended with 47, linen, etc., and carbon, sulfur, various fillers, etc. added to the rubber for studless tires on both sides. Paint like 48

Using a tool machine such as 49 in FIG. 30 in the longitudinal direction of the cloth such as hemp coated with the blended rubber, the wrinkle is made at the center as shown in 50 in FIG. 31 [FIG. 32]. No. 51 is in a state where wrinkles are made in the center in the vertical direction on linen etc.

A tool such as 53 in the same width as 52 in FIG. 33, which is the same as the height of the tread portion in a state where the studless tire is rounded with a cloth such as hemp wrinkled in the center in the vertical direction. Fold it into an accordion using a machine [Fig. 34] 54 is linen etc.

About a formwork with a width like 56 in [Fig. 35], which is the same width as the length of the tread when the studless tire is rounded, such as linen folded at the same height as the tread Insert a cloth such as hemp in a folded state and press it with 55 to harden it into a plate shape. [Fig. 36] is hardened into a plate shape.

The lined cloth is wrapped around the carcass of a drum that is producing studless tires, but before being wrapped, both sides of the cloth such as linen with a width narrower than the width of the sheet, such as linen folded in an accordion Wrapped around the center of the carcass with the compounded rubber applied to the center of the carcass (Fig. 25). As shown in No. 41, this is a linen made by winding compounded rubber on both sides, such as sandwiched linen wrapped around a carcass, and then folding it into an accordion shape and applying compounded rubber on both sides In order to prevent gaps between the sides of the compound rubber applied to both sides of the hemp, etc. of the width that was previously wound

[Fig. 36] is wound around the carcass as shown in [Fig. 26] 42. At the same time, the central part of plate-like objects such as linen wrapped up is raised.

The length of the accordion-like linen or the like wrapped around the carcass may be the length of one turn around the carcass, but it may be divided into several times and wrapped around the carcass. This is the same in the manufacture of claims 9 and 0058.

Attach the green cover wrapped around the carcass to the mold plater of the vulcanizer and inflate it at high temperature and pressure to mold it into a studless tire

At that time, compound rubber was applied to both sides of linen, etc., folded in an accordion shape, wrinkled in the center and formed into a plate shape, wrapped around the carcass, and inflated with high temperature and high pressure steam, When molded into a studless tire, it is deformed into the shape of an arc of a ring (Fig. 24). The shape is molded by moving to and stretching.

The surface of the tread part molded in the studless tire has been changed from compounded rubber to elastic rubber, so the surface is mixed with water or heavy liquid with steel powder etc., and the studless tire molded with it The steel powder that sprays on the entire surface of the tread part and scrapes off the thin rubbery material with surface elasticity and exposes linen etc. enters the rubbery part of the tread part, so remove it with a rotating file etc.

If you want to scrape the surface, you can scrape with a rotating file, or use various scraping methods. Applying water to the shaving area and pouring it down with the shavings or dropping the shavings down with a good wind

A groove is dug in the tread part of the studless tire as shown in [Fig. 37] to improve the grip on the snow and ice surface, and siding is added as in 58 to further increase the flexibility and moisture absorption on the snow and ice surface. The moisture absorption is further increased by absorbing the moisture from the exposed linen, etc. and draining the absorbed moisture from the linen on the side of the trench. The braking power on the ice and snow surface becomes better,

The thickness of the blended rubber is adjusted on both sides of the linen, etc., and when it is molded into a studless tire, the density of the linen of the tread portion, the density of rubber, the hardness and strength are adjusted.

The manufacturing method according to claim 11 is a method of forming a yarn by applying a wear-resistant fiber such as hemp or aramid, which can withstand high temperatures, and the studless tire has the same black color or studless so as not to reduce moisture absorption. It may be dyed in other colors that differ from the tire color.

Cut the thread longer than the raised rubber width between the groove that scratches the grip of the studless tire tread and the groove that scratches the grip, and make many of them.

Studless tire rubber, carbon, sulfur, various fillers, etc. are added and mixed well to make a compound rubber, and mixed together with many hemp threads cut in the above [0087]

The mixing ratio is more hemp and other threads than compounded rubber, and when the quality changes from compounded rubber to elastic rubber so that the hemp and other threads stick together, the hemp and other threads that stick together often The studless tire tread must be strong enough to withstand strength when it is running in a car.

Stirless tire tread parts are made into a plate shape as shown in [Fig.

It is wound around the drum carcass in the course of manufacturing the studless tire as shown in FIG.

If a thin plate of a mixture of hemp or other thread and compounded rubber is used, the first sheet may be wrapped with adhesive on the entire surface. After the first piece, the adhesive is applied as a spot on the edge, and it is wound to the thickness of the tread of the studless tire.

The raw cover made in this way is attached to the mold platter of the vulcanizer and inflated with high-temperature and high-pressure steam to form a studless tire.

Since the rubber of the tread part of the molded studless tire has been transformed into a rubber with elasticity, moisture cannot be absorbed from the thin rubber on the surface of the tread.

Steel powder etc. mixed with water or heavy liquid mixed with steel powder etc. are vigorously sprayed on the surface of the tread part, and the thin rubber material on the surface of the tread part is scraped off to expose thread such as hemp etc. Since it gets into the rubber, it is shaved with a rotating file.

Rotate file or water that can be shaved by various methods is applied to the shaving location, and the shavings etc. are poured down together or a good wind is applied to drop the shavings etc.

In the tread with exposed threads such as hemp, a groove is dug as shown in 60 of [Fig. 40] and the grip on the snow and ice surface is made well, and siding is added as shown in 61 to have flexibility on the ice and snow surface. By absorbing moisture from the exposed hemp or other thread, the moisture is discharged from the hemp or other thread from the side of the groove dug through the thread. As a result, the water absorption is further increased and the braking force on the ice and snow surface is improved.

In the manufacturing method of claim 12, the rubber for manufacturing the studless tire tread portion is added with carbon, sulfur or various fillers, and mixed well. Make a compounded rubber that is mixed well so that it is mist-like or colloidal

Make the surface of the tread part where the compounded rubber was molded into a plate shape that is thicker, including the part to be shaved so that it becomes the thickness of the tread part after being easily absorbed by moisture.

It is wrapped around the carcass of the drum in the studless tire manufacturing process, and the compounded rubber is thinned and stacked several times on the carcass. When weighing together, the adhesive is glued as a point on a thin plate

A carcass wrapped with compound rubber is attached to a mold platter of a vulcanizer and inflated with high-temperature, high-pressure steam to form a studless tire.

When puffing and forming, when the mold is inflated and the temperature rises, the mist and colloidal water in the compounded rubber boils, creating a lot of minimal space in the tread rubber.

If the mist or colloidal water in the compounded rubber does not reach a high temperature until boiling, even if the studless tire is inflated with a mold, the mold in contact with the surface of the puffed studless tire tread In FIG. 41, a space for sending high hot air as indicated by 62, or a temperature at which the water in the tread part is vaporized and mist-like or colloidal is evaporated, as indicated by 63 and heated by electric heat. Make

Since the rubber material put in the mold and inflated is under pressure, a certain temperature is required to evaporate the water in the form of mist or colloid.

If the temperature is too high, it will change from the compounded rubber to the rubber of the studless tire tread, but it will change or deteriorate, so it will not be too high and the water will evaporate at 1 atm. Up to

Even if it is attached to the mold plater and inflated with high-temperature and high-pressure steam, the high temperature is transmitted to the tread part from the state where it still does not fit in the mold, and the water rises to the boiling temperature. There may be a case where a very small sky is created, so you can fit it in the mold as it is,

The pressure rises on the rubber in the tread part from a little before entering the mold, so that the temperature rises and the water evaporates so that it can evaporate even after it gets into the mold so that a lot of minimal space is created.

The finished studless tire tread part is in contact with the mold. The surface created by the evaporation of mist or colloidal moisture may not be obvious due to the heat of the mold surface. To expose a lot of minimal space

The method of scraping can be a very fine rotating file or various methods, but scraping so that the scraps and scraps of the file do not enter the minimum space, scraping with a file etc. under the tread surface. So that it does not hit the surface of the tread part and falls down, it is poured with water and applied to the shaving place, and the shavings etc. are dropped with the water under the shavings and the good wind is shaved into the shaving place. Blow off and scrape off the scraps.
Only the surface is shaved, and if the surface of the tread part has a lot of very small spaces (holes), it is not necessary to scrape.

A groove is dug in the tread part where a lot of minimal space is exposed so that the grip on the snow and ice surface is well absorbed, moisture is absorbed from the numerous minimal space of the tread part, and siding is put into the tread part and the ice and snow surface Moisture absorbed and increased moisture absorption is discharged from a lot of minimal space from the side of the dug groove, and more moisture absorption is improved on ice and snow surfaces. The braking power is good

The ratio of mixing water into the compounded rubber is the ratio at which mist or colloidal water evaporates to create a lot of minimal space. Mixing a lot of water creates more minimal space and absorbs moisture. However, the strength is weak and mixing with a little moisture can reduce the minimum space and the moisture absorption rate is not good, but the strength is inflated with high temperature, high pressure steam and put in the mold to mix the rubber from the studless tire tread part It depends on the ratio of the size of the numerous spaces due to the relationship between the pressure of the rubber when it changes to rubber, the size of the mist and colloidal water particles and the expansion force of evaporation. The rubber strength and flexibility of the studless tire tread must be strong enough to withstand long distances and long distances in the car.

When a studless tire is molded by inflating a raw cover with high-temperature and high-pressure steam and molding it into a mold, the rubber quality of the studless tire tread changes from the compounded rubber at high temperatures, and mist and colloidal water evaporates. Moisture that evaporates when a lot of minimal space is created in the tread part, by making some thin grooves as shown in 64 in FIG. Like to let the steam escape

Claim 9 and 10 for adding a little water to the compounded rubber, mixing it well, winding it around the carcass and inflating it with high-temperature and high-pressure steam to produce a rubber material for a studless tire tread having a lot of minimal space. Applying a little bit of water as in Claim 12 to the compounded rubber to be applied to the fabric such as hemp, etc. and applying the compounded rubber mixed well to make a studless tire tread part to absorb more moisture, hemp etc. Strengthens by sharing with other fabrics, and hemp fabrics and rubber blends to increase strength.
The rubber blended with the yarn and fiber of claim 11 is mixed with the rubber blended with the water of claim 12 and mixed well with the thread and fiber of hemp and so on to form a studless tire tread portion. Improves water absorption and increases strength by tangling threads and fibers such as hemp and compounded rubber

The method according to claim 13 mist and colloidal well mix by adding a little trichloromethane [chloroform] CHCl ₃ in compounded rubber mixed well by adding such as carbon, sulfur and various fillers for rubber studless tires A rubber compound containing trichloromethane

After it is molded into the studless tire tread part, it is wrapped around the carcass thickly, including the part that is cut to the same thickness as the tread part when the surface is shaved. If you are going to wrap, glue the point

It is attached to the mold ladder of the vulcanizer and inflated with high-temperature, high-pressure steam to form a studless tire.

At that time, when the compounded rubber becomes rubbery in the studless tire tread part at a high temperature, the trichloromethane contained in a mist or colloid has a boiling point of 61.2 ° C. at 1 atm and evaporates at a temperature lower than water. Creates a studless tire tread with plenty of space and very good moisture absorption.

If the temperature is too high to change from the compounded rubber to the studless tire tread, it will change or deteriorate when the compounded rubber changes to the rubber of the studless tire tread. (Trichloromethane, which is inflated with high-temperature, high-pressure steam in a mold and contains mist or colloidal form) Trichloromethane evaporates to create a lot of minimal space even if it is not so hot, to make a studless tire,

Mix trichloromethane well with compounded rubber and inflate with high-temperature, high-pressure steam in the mold to change the rubber from the compounded rubber to the rubber quality of the studless tire tread, so that it is elastic in the mold, so pressure on the rubber The trichloromethane, which is in the form of mist or colloids, evaporates at a pressure of 11.2 atm or higher, but evaporates at a pressure of 61.2 ° C or higher. Push and evaporate to create a lot of minimal space

Trichloromethane does not dissolve rubber, so it can be mixed well

Add carbon, sulfur and various fillers to the rubber for studless tires and mix well. Add a little carbon tetrachloride [tetrachloromethane] Ccl ₄ and mix well to make mist or colloidal carbon tetrachloride. Make the included compound rubber

When it is molded into a studless tire and wrapped around the carcass thickly, including the shaving, so that the thickness is the same as the thickness of the surface of the tread, and when thinly stacked, Glue is glued at point,

Attach it to a mold plater and inflate it with high-temperature, high-pressure steam to form a studless tire.

At that time, carbon tetrachloride contained in a mist or colloid when the compounded rubber becomes rubbery at high temperature and pressure at the studless tire tread part has a boiling point of 1 atm 76.74 ° C and evaporates at a temperature lower than water. Create a studless tire tread with lots of minimal space and very good moisture absorption

When it changes from compounded rubber to rubber in the studless tire tread, it will change or deteriorate if it is too hot, so carbon tetrachloride is mixed well into the compounded rubber and included in a mist or colloid mold Inflating with steam at high temperature and high pressure at this time, even if it is not so hot, the carbon tetrachloride contained in mist or colloid evaporates to create a studless tire tread part where a lot of minimal space was made

Add a little carbon tetrachloride to the compounded rubber and mix it well with a high-temperature, high-pressure steam in the mold and change the compounded rubber to the rubber quality of the studless tire tread part. Since carbon tetrachloride, which is in a rubbery state and is in the form of mist or colloid, evaporates by pushing the pressure because it is fitted, carbon tetrachloride will evaporate unless it is at 1 atm 76 or 74 ° C or higher. However, even if the temperature is not too high, the pressure of the rubber is pushed away to evaporate and a studless tire tread part that creates a lot of minimal space is built.

Carbon tetrachloride does not dissolve rubber, so it can be mixed well

The mixing ratio of trichloromethane and carbon tetrachloride to the compounded rubber is the ratio that the trichloromethane and carbon tetrachloride contained in the mist or colloid form can be evaporated to create a lot of minimal space. If the compound rubber contains a lot of carbon in the form of mist or colloid, a lot of space is created and the moisture absorption rate is good, but the strength of the tread part is weak. If it is included, there are a lot of minimal spaces and the moisture absorption rate is not good, but the strength of the tread part is strong and it is inflated with high temperature and high pressure steam and fitted in the mold to change the rubber from the blended rubber to the studless tire tread part Sometimes it depends on the ratio between the pressure of rubber and the size of mist or colloidal particles such as trichloromethane and carbon tetrachloride and their expansion expansion force. Determined by the ratio of the size of the can be very small space

The mixing ratio of trichloromethane and carbon tetrachloride to the compounded rubber makes the rubber strength and flexibility of the studless tire tread part strong enough to withstand long distances in the car.

Trichloromethane and carbon tetrachloride are weakly toxic and contain chlorine. If they are scattered in the air, they will affect the human body and destroy the ozone layer.

Trichloromethane evaporated in the sealed container when the entire mold was covered with a sealed container as shown in 66 in FIG. 43 when it was inflated with high temperature and high pressure steam in the mold of the vulcanizer As shown in 67 in Fig. 43, the carbon tetrachloride is put out from a faint space with a narrow groove like 64 in the mold, and trichloromethane and carbon tetrachloride are heavier than air and remain under the sealed container. In order to collect trichloromethane and carbon tetrachloride and use them again, install a thin groove in the place where the upper and lower surfaces of the mold come into contact. Put a book or a faint space to escape evaporated trichloromethane or carbon tetrachloride

Add a little trichloromethane or carbon tetrachloride to the compounded rubber, mix well, add it in a mist or colloidal form, wrap it around the carcass and inflate it with high-temperature, high-pressure steam in a mold to evaporate trichloromethane or carbon tetrachloride. If the temperature of the compound rubber is not enough to evaporate trichloromethane or carbon tetrachloride in the mold,

A high temperature steam or hot air is sent to the mold in contact with the surface of the puffed tread part. A space like 62 in [Fig. 43] is created, or 63 parts in the mold part in contact with the surface of the tread part are provided. To increase the temperature at which trichloromethane and carbon tetrachloride evaporate.

The surface of the tread part molded in a studless tire with a lot of minimal space made by evaporation of trichloromethane and carbon tetrachloride may not be made into a clear shape, so there are a lot of scraped surfaces Expose the minimal space

The surface of the tread can be scraped with a rotating, very fine file or various methods, so that no shavings or filings can enter the space, and the surface of the tread is scraped with a file. Scraping, dropping shavings etc. down, hitting the water against the shaving location and pouring the shavings etc. down or blowing with a good wind to drop shavings etc. down,
Only the surface of the tread is shaved. If the surface of the tread is clear in many spaces (holes), it does not need to be shaved.

As shown in 68 of FIG. 44, a tread portion where a lot of minimal space is exposed is dug as shown by 69, and the grip on the snow and ice surface is pierced so that it is not a groove. As shown in Fig. 70, siding is added to improve the flexibility on the snow and ice surface and the absorption of more moisture, and the absorbed moisture is also discharged from the minimal space on the side of the dug groove and more moisture is absorbed. Improves absorption and improves braking power on ice and snow.

A studless tire tread portion may also be formed by applying the compounded rubber according to claim 13 to the cloth such as hemp according to claims 9 and 10.

The thread and fiber such as hemp of claim 11 are also mixed well with the rubber and fiber such as hemp of claim 13 to form a studless tire tread portion.

By using it with cloth or thread or fiber such as hemp, the moisture absorption rate and strength can be increased more effectively. Threads and fibers are entangled with compounded rubber and inflated with high-temperature and high-pressure steam in a mold to change into elastic rubber with numerous minimal spaces, and cloth, threads and fibers such as hemp are entangled with it Because it has strength

In the drawings in which the studless tires in the previous claims are rounded, the tread part shows grooves and siding etc. It matches the shape of the groove that the tread part of the actual studless tire digs and the direction of siding do not do

In the meantime, a plate-shaped object entangled with wear-resistant finely knitted fibers that can withstand high temperatures such as hemp and aramid is attached to the carcass during tire manufacture and used as a mold ladder for the vulcanizer When attached and inflated with high-temperature, high-pressure steam to form a tire mold, the thin fibers adhere to each other more than necessary at high temperature and pressure, so the space rate does not go down and moisture absorption increases, making the tire tread more In the case of preventing the production, a thin plate-like product entangled with the fine fibrous rubber produced in claim 2, 4, and 5, and a fine fibrous rubber Entangled with high temperature such as hemp Glue the fluffy plate-like material that is entangled with the finely chopped fibers that can withstand, and bond with the pressure heat so that the thin fibers overlap with each other in a cruciform shape and only the crossed parts are bonded. To make the tread part of the tire, and in that case the fluffy plate-like thing made by entangled fine fibrous rubber and the finely knitted fiber that can withstand high temperatures such as hemp entangled and fluffy The thickness of the fluffy plate-shaped object is also produced by applying pressure to the fluffy plate shape with the same amount as the thickness of the tread part of the tire. Create a tire tread by applying pressure so that the tire tread is molded into a tire size mold and curve,
A carcass that is currently being manufactured into tires is part of a carcass that has been trimmed into a tire shaped carcass that has been inflated with high-temperature, high-pressure steam using a special vulcanizer mold platter. Make a studless tire by securely bonding the cut tire tread to the carcass with an adhesive, digging a groove in the tread to make a grip on the snow and ice, and scribing the tread on the snow and ice. Make it easier to absorb the moisture of the water and increase braking on ice and snow, In the case of producing claims 2, 4, 5, 6, and 7, when fine fibrous rubbers are difficult to adhere to each other, it is poured into the fine fibrous rubber at high temperature and high pressure that melts the compounded rubber for studless tires. If two machines are put out and hot air is sent from both sides to create a thin fibrous rubber and entangle the thin fibrous rubber, a fine mist with a little viscous liquid adhesive with hot air on both sides It is made to fly in the shape of a thin fiber rubber and attached to a fine mist. In this case, attach a rubber tube that sends air pressure to the device that makes the liquid adhesive mist, spray the liquid adhesive from the device in a mist, and attach it to the thin fibrous rubber together with hot air to make the thin fibrous rubber In order to prevent the liquid fiber rubbers that are entangled with each other from crossing each other, the liquid adhesive is slightly glued, and the parts that are not crossed are not adhered. Thin fiber

Or more,
Use a liquid adhesive that is suitable for the high or low viscosity of the adhesive or the evaporation of petroleum-based materials containing the adhesive, or adjust the temperature of hot air to prevent the adhesive from drying too quickly. Also, when tangle fine fibers that can withstand high temperatures such as hemp that regulates so that it does not slow down drying, the same is true where thin fibrous rubber is crossed, such as hemp and aramid Abrasion-resistant fine fibers that can withstand high temperatures Adhere a little when they are crossed or in contact with each other. In the place where the finely chopped fibers are not crossed or in contact with each other, the adhesive is adjusted so as not to dry and adhere.
Even if a thin fibrous rubber that is completely dry is sent by sending hot air, it can be attached to a mold ladder of a vulcanizer and inflated with high-temperature, high-pressure steam to produce a studless tire. In the place where the cross-like shape of the thin fibrous rubber is bonded,
Even if a tread part of a studless tire is produced by applying high pressure to a thin fibrous rubber-like tangled and fluffy plate-like material, it becomes a cross shape in which fine fibrous rubber is entangled with pressure heat Where it is A cloth woven with a wear-resistant fiber that can withstand high temperatures, such as hemp and aramid. The cloth such as hemp is cut to the same width as the tread part of the studless tire, and the length is slightly shorter than the tread part when the studless tire is cut off. The center part of the cloth such as hemp cut to the same width as the tread part is cut a little wider and raised to a raised state, and the studless tire rubber on both sides of the linen is made of carbon, sulfur, Apply various types of fillers and mix well with compounded rubber, wrinkle the center of the linen, put several pieces of the linen together into a plate, and wind it around the carcass. And wind it around the carcass The attached plate-shaped central part is slightly swelled, and the center part such as linen with the compounded rubber coated on both sides is crumpled, and the vulcanizer A studless tire is molded by inflating with high-temperature and high-pressure steam when it is attached to a mold plater of this type. At this time, compounded rubber is applied to cloth such as linen wrapped around the carcass when molded into a studless tire at high temperature and pressure. When the plate-like material is swelled at high temperature and high pressure and formed into an arc shape in the tread part, the wrinkled parts of the compound rubber and linen move from the raised center part of the plate shape to both ends. When the linen is cut to a straight width without the center part being raised and compounded rubber is applied to both sides, and the wrinkles are overlapped with the center part to make a plate shape, the width is put first. Combines both sides of linen It painted in the put Hari around the carcass, a little boost the central portion of the carcass, on it,
A piece of cloth, such as linen cloth, is cut into a straight line with the same width as the tread and coated with rubber compound on both sides. The central part where it is wound up is raised.
The thickness of the blended rubber is adjusted on both sides of the linen and when it is molded into a studless tire, the density of the linen in the tread part, the hardness and strength of the rubber are adjusted.
Since the tread part of the studless tire that has been removed from the mold of the vulcanizer has changed from compounded rubber to elastic rubber, water or heavy liquid is used to scrape the thin elastic rubber on the tread surface. Mix the steel powder and blow it onto the tread surface of the studless tire.

As you squeeze out, you can add siding to improve flexibility and more moisture absorption, so that braking on the ice and snow surface works well, and moisture absorption on the ice and snow surface from the linen on the tread surface Moisture that has been sucked in is attached to the linen and discharged from cloth such as linen on the side of the groove, so it absorbs more moisture and brakes on ice and snow are better.
Linen can be dyed in the same color as the studless tire, such as black, or other colors so that moisture absorption does not decrease.
If the surface of the tread is blown with a liquid containing steel powder, the steel powder will be trapped in the rubber of the tread, so water will be applied to the rotating place that is extremely finely frayed and scraped in various ways. Touch and drop the shavings etc. with the water or the shavings etc. Hemp and other fabrics that are woven into cloth using hemp or aramid and wear-resistant fibers that can withstand high temperatures. Okay, you can dye the linen and other fabrics with a black color that is the same as the color of the studless tire or a color that is not the same as the color of the studless tire.
Cut the linen etc. slightly longer than the width of the tread when the studless tire is cut off (this is the length to make the center part wrinkle a little) and cut the length into a studless tire The length of the tread part of the tread part is longer than the circle of the rotating surface, and the length of the tread part is in the accordion shape over the width of the tread part when the studless tire is cut off. It is a length that goes around the circle on the surface of the tread portion of the size of the studless tire.
Add rubber, carbon, sulfur, and various fillers to studless tire rubber and mix them well on both sides of the linen, etc., and coat the linen with the same width as the tread height of the studless tire. Before folding, crease it slightly like the vertical center of the linen and fold it into an accordion with the same width as the tread. Then, blend rubber on both sides of the linen that is narrower than the width of the accordion-like plate, and wrap it around the center of the carcass to raise the center of the carcass and fold it into an accordion A sheet of cloth such as linen is wrapped around, and the central part of the sheet is rolled up, such as linen folded in an accordion The cloth plate may be in length is the length to give Hari around the carcass to go around the carcass in one of such, but may be a length to give Hari wound after circling the carcass is divided into several times.
Attach the green cover wrapped around the carcass to the mold plater of the vulcanizer and inflate it at high temperature and pressure to form a studless tire. At that time, compound rubber is applied to both sides of the linen to wrinkle the vertical center of the linen. Folded into an accordion shape and wrapped around a carcass and inflated with high-temperature and high-pressure steam, the plate-like object is transformed into a ring arc when molded into a studless tire. When it is done, the wrinkles and compounded rubber in the center part of the linen sheet are moved from the center part toward both end parts, and the shape is molded with good tension.
The surface of the tread part molded in the studless tire has changed from compounded rubber to elastic rubber, so the surface is mixed with water or a liquid with high specific gravity and steel studs are molded into the studless molded tire. Tire tread

Ditch a groove to improve grip on the snow and ice surface and add siding to increase flexibility and moisture absorption on the ice and snow surface to absorb moisture from hemp and other cloth on the surface Moisture absorption that has been transmitted from linen on the side of the groove that has been dug is also discharged, so that moisture absorption is further increased and braking on ice and snow becomes better.
If the liquid containing steel powder is blown vigorously to scrape the surface of the tread, the steel powder will be hard to squeeze the tread surface. Put the scraps down against the water and blow them down with water, or blow a good wind and let the scraps flow down Even if it is dyed in the same color as the studless tire or other colors so that the moisture absorption of the yarn does not decrease by applying it with a fiber such as wear-resistant hemp or aramid that can withstand high temperatures Good.
Cut the thread longer than the raised width between the grip groove of the studless tire tread and the groove, and make a lot of it. Add a filler and mix well to make a compounded rubber, mix well with the compounded rubber and a lot of hemp threads with the above-mentioned sides cut, and the mixing ratio is more hemp threads than compounded rubber. When blended rubber is transformed from elastic rubber to elastic rubber so that it sticks well, the hemp threads that stick well together harden together to give strength, and the strength that can be withstood when the studless tire tread is running in a car What is
Hemp and other yarns and compounded rubber are mixed in a plate shape so as to have the thickness of the studless tire tread, and wrapped around the carcass of the drum during the studless tire manufacturing process and hemp and other yarns and compounded rubber If you mix and paste many pieces of thinly mixed into a thin plate, you can apply the adhesive on the entire first sheet and wrap it around, but after the second one, the adhesive Attach the adhesive as a point and wrap it so that it becomes the thickness of the studless tire tread part. Attach the raw cover thus made to the mold ladder of the vulcanizer and inflate it with high temperature and high pressure steam Molding into studless tires,
Since the rubber of the tread part of the molded studless tire has been changed to rubber with elasticity, moisture cannot be absorbed from the thin rubber of the surface of the tread part.

You can sharpen the texture, use a rotating file or various other methods. Shaving thin rubbery surface to expose hemp thread etc. on the surface and digging grooves to make grip on snow and ice surface better, adding siding to give flexibility and more moisture Improves absorption, absorbs moisture from exposed hemp yarn, etc., and drains moisture from hemp yarn on the side of the groove dug through the hemp yarn, etc., and braking on ice and snow surfaces is good,
The surface of the tread surface can be scraped by using a very fine rotating file or a variety of other methods. Pour water over the spilled area to flush the shavings, etc. or blow a breeze to drop the shavings down Studless tire tread parts are made of rubber, carbon, sulfur, various fillers, etc. and mixed well. A little water is added to the rubber. Mix well and make the compounded rubber and thicken it including the amount to be shaved so that the surface of the tread part where the compounded rubber was molded easily absorbs moisture and becomes the thickness of the tread part When making a plate and winding it around the carcass of a drum in the manufacturing process of a studless tire, thinning the compounded rubber and stacking several pieces on each other and winding them around the carcass, use a thin plate with an adhesive. When multiple sheets are stacked, the adhesive is glued to a thin plate as a spot. A carcass wrapped with compound rubber is attached to the mold of the adder and inflated with high-temperature and high-pressure steam, and then stud studs are attached. When molding at the time of molding into a tire, the mist and colloidal water in the compounded rubber boiled when the mold was inflated into a mold and it became hot, and a lot of minimal space was created in the rubber of the tread part If the temperature does not become too high even when the studless tire is inflated with a die, the space where the hot air is sent to the die that is in contact with the inflated studless tire tread and the temperature of the tread part is increased by electric heat. The temperature is enough to evaporate the water in the form of mist or colloid.
The rubber that is put in the mold and inflated is put in the mold, so pressure is applied, so the power of the temperature to evaporate is necessary,
If the temperature is too high, it will change from the compounded rubber to the rubber of the studless tire tread, but it will change or deteriorate, so it will not be too high and the water will evaporate at 1 atm. Even if it is attached to a mold plater and is inflated with high-temperature and high-pressure steam, the high temperature is transmitted to the tread part from the state where it is not yet attached to the mold, and the water rises to the boiling temperature and the water evaporates. There are cases where a lot of minimal space may be created, so you can fit it in the mold as it is, but since the pressure on the rubber of the tread part is not so much applied from the moment before it gets into the mold, the temperature rises and moisture Studless tire tread part that can be evaporated to create a lot of minimal space after evaporating and getting stuck in the mold The surface made in contact with the mold is foggy Colloidal water exposes a number of very small space also dropped shear cut surface because there is a case where a very small space made by evaporation is not clear like mold surface heat,
The method of scraping is a rotating file or various methods that expose a lot of minimal space by scraping the surface of the tread part with a force of water or heavy liquid mixed with steel powder etc. A method of surface shaving with a rotating file or the like is recommended to spray steel powder that can be shaved in a vigorous manner so that the steel powder does not enter the numerous spaces in the tread. Applying water to the location where you want to scrape, drop the scraps with the water while flowing the water, or scrape the scraps with a good wind,
Grooves are made in the tread part where a lot of minimal space is exposed, and water is absorbed from the numerous minimal spaces of the tread part so that the grip on the snow and ice surface is well absorbed. Moisture that has been absorbed by increasing the amount of moisture and absorption of water at the moat is exhausted from the numerous spaces from the side of the groove to the moat, improving the absorption of more moisture on the snowy surface The braking power is good.
The surface of the tread part is scraped only on the surface, and when there are many very small spaces (holes) on the surface of the tread part, it is not necessary to scrape it with a very fine file that rotates under the tread part surface. Shaving and dropping the shavings etc. down The water is applied to the shaving location and the shavings etc. are poured down with the water or blown with a good wind to drop down the shavings etc. The ratio of mixing water into compounded rubber that can be scraped in various ways, but does not allow scraps such as scraps and files to enter the minimal space. If you mix a lot of water, you can create a lot of minimal space and have a good water absorption rate, but the strength is weak, and if you mix a little water, there is little space and the moisture absorption rate is not good, but there is strength Evaporation expansion force between the pressure of the rubber and the amount of water in the form of mist or colloid when the rubber is inflated with hot and high pressure steam and fitted into the mold to change the rubber of the studless tire tread It is also determined by the proportion of the size of a lot of minimal space due to the power relationship with
The rubber strength and flexibility of the studless tire tread part, and the strength that it can withstand even if it travels a long distance for a long time in a car. When molding tires, the quality of the rubber changes from compounded rubber to the studless tire tread at high temperatures, and when the mist or colloidal water evaporates to create a lot of minimal space in the tread, Add some thin grooves in the place where the top and bottom are in contact to create a slight gap (clearance) so that the evaporated vapor is released. Add a little water to the compounded rubber and mix well and wind it around the carcass.・ Rubber to be applied to cloth such as linen of claim 9, 10 to make a rubber material of a studless tire tread portion in which a lot of minimal space is inflated with high-pressure steam No. 12 Claims to add a little water and mix well mixed rubber to make a studless tire tread part to absorb more moisture and to share strength with cloth such as hemp The studded tire tread is made by blending the blended rubber mixed with the blended rubber of Item 11 with a little water into the blended rubber blended with the thread and fiber of Item 11 and well mixed with the thread and fiber fiber of hemp. To increase the water absorption and increase the strength by sharing the linen and thread. Studless tire rubber was mixed with carbon, sulfur and various fillers and mixed well. A little trichloromethane [chloroform] CHCl ₃ was added and mixed well to add trichloromethane in a mist or colloidal form. Make a compound rubber and wind it around the carcass thickly, including the amount of the tread part that has been cut to the same thickness as the surface of the studless tire tread.

Attach to a mold plater and inflate with high-temperature and high-pressure steam to form a studless tire. At that time, when the compounded rubber becomes rubbery at the studless tire tread part at high temperature, the trichloromethane contained in the mist or colloid form has a boiling point Is 61.2 ° C at 1 atm, and it evaporates at a temperature lower than water, creating a lot of minimal space. Even if the temperature is not so high, trichloromethane evaporates and becomes a studless tire tread part from compounded rubber However, if it is too hot, it will change or deteriorate when it changes from compounded rubber to studless tire tread rubber, so trichloromethane is mixed well with compounded rubber and inflated with high temperature and high pressure steam in the mold and fog Even if the trichloromethane contained in the form of colloids is evaporated at such a high temperature, it evaporates to create a lot of minimal spaces. The trichloromethane that forms the studless tire tread part does not dissolve the rubber, so the trichloromethane that is often mixed is mixed well with the compounded rubber and inflated with high-temperature and high-pressure steam in the mold to change the compounded rubber to the rubbery of the studless tire tread part. Since it has elasticity in the mold, it has a pressure on the rubber and mist or colloidal trichloromethane evaporates by pushing the pressure over 61.2 ° C. Although it evaporates at a high temperature, even if it is not too high, it mixes well by adding carbon, sulfur and various fillers to studless tire rubber that evaporates by pushing away the pressure of rubber and creates a lot of space Carbon tetrachloride [tetrachloromethane] CCl ₄ was added to the mixture and mixed well to form a mist or colloid to contain carbon tetrachloride. Make compounded rubber,
When it is molded into a studless tire and then it is wrapped around the carcass thickly, including the part that is shaved to the same thickness as the surface of the tread part, and when thinly stacked, Glue is glued at point,
It is wrapped around a mold plater and inflated with high-temperature, high-pressure steam to form a studless tire.
At that time, carbon tetrachloride contained in a mist or colloid when the compounded rubber becomes rubbery in the studless tire tread part at high temperature and high pressure has a boiling point of 76, 74 ° C at 1 atm and evaporates at a temperature lower than water. If the temperature is too high when changing from compounded rubber that creates a studless tire tread with a lot of minimal space to a studless tire tread, it will deteriorate or deteriorate, so carbon tetrachloride is often mixed with the compounded rubber. Even if it is included in the form of mist or colloid and inflated with high-temperature and high-pressure steam in the mold, the mist and colloidal carbon tetrachloride evaporates without creating such a high temperature, and a lot of minimal space is created. Build a studless tire tread,
Add a little carbon tetrachloride to the compounded rubber and mix it well with a high temperature, high pressure steam in the mold, and the rubber will change from the compounded rubber to the rubber of the studless tire tread part. Because it is in a mold, the pressure of the rubber and the carbon tetrachloride in the form of mist or colloid evaporates by pushing the pressure, but it does not evaporate at a temperature of 1 atm. Don't be too hot, but evaporate by pushing away the pressure of rubber and create a lot of minimal space,
Carbon tetrachloride does not dissolve rubber, so if you mix trichloromethane and carbon tetrachloride well into a compounded rubber that can be mixed well, trichloromethane and carbon tetrachloride will evaporate if the compounded rubber is heated too high due to frictional heat etc. In order to prevent the temperature from rising too much, mix it slowly until the maximum temperature reaches about 50 ° C, or mix it while applying cold air when mixing at high speed, or increase the temperature of the compounded rubber that is mixed by cooling the mechanical hardware to be mixed The ratio of mixing trichloromethane and carbon tetrachloride into the compounded rubber to be suppressed is the ratio of mixing trichloromethane and carbon tetrachloride at a ratio that allows evaporation of mist and colloidal trichloromethane and carbon tetrachloride to create a lot of minimal space. More space can be created, but the moisture absorption rate is very good, but the strength of the tread is weak. The number of spaces is small and the moisture absorption rate is not good, but the strength of the tire tread part is strong. It is inflated with steam at high temperature and high pressure and fitted in the mold to change the rubber quality when changing from compounded rubber to rubber of the studless tire tread part. The studless tire tread part is also determined by the ratio of the size of the minimal space that can be created by the ratio of the pressure and the size of the mist and colloidal trichloromethane and carbon tetrachloride grains and the force relationship with the expansion force of evaporation. The strength and flexibility of rubber and the strength enough to withstand long-distance driving for a long time in a car. Trichloromethane and carbon tetrachloride are weakly toxic and contain chlorine, so they are in the air. If it blows up, it will affect the human body and destroy the ozone layer, so when the vulcanizer mold is inflated with high-temperature, high-pressure steam, the entire mold is sealed. Collect trichloromethane and carbon tetrachloride evaporated in a sealed container and add a little trichloromethane and carbon tetrachloride to be used in the compounded rubber and mix well. It is wrapped in a carcass and inflated with high-temperature, high-pressure steam in a mold to evaporate trichloromethane and carbon tetrachloride to create a large number of spaces. If the mold contains rubber compounded with trichloromethane or tetrachloride If the temperature is not enough for carbon to evaporate, create a space to send high-temperature steam or hot air to the mold part in contact with the surface of the puffed tread part, or make contact with the tread part surface Numerous minimal spaces created by evaporation of trichloromethane and carbon tetrachloride, such as by heating the mold part with electric heat to raise the temperature to evaporate trichloromethane and carbon tetrachloride The surface of the tread part molded on a studless tire with a rim is in contact with the mold and the minimal space may not be clear, so the surface is scraped to expose many minimal spaces.
You can scrape with a rotating file or a variety of methods, but do not put the scraps or scraps of scrape into the minimal space. If you dig a groove in the tread part where a lot of minimal space is exposed and drop the file, etc. The moisture absorbed by improving the flexibility of the water and increasing the amount of moisture is also discharged from the side of the dug groove, improving the absorption of more water and improving the braking force on the ice and snow surface well Studless tires in tread where a small amount of trichloromethane or carbon tetrachloride is added to rubber and mixed well in the form of a mist or colloid and wrapped around the carcass to create a lot of space with high-temperature and high-pressure steam. The A studless tire tread portion is also formed by applying the compounded rubber of claim 13 on the fabric of hemp or the like of claim 9 or 10 for making the yarn or fiber of hemp or the like of claim 11 or 13 Studless tire tread part is also made by mixing rubber and fiber such as hemp and fiber well.
By using it with cloth or thread or fiber, such as hemp, it is possible to increase the water absorption rate and strength, which can be more effective. Involved in compound rubber and swelled with high-temperature and high-pressure steam in the mold, and changed to elastic rubber with a lot of minimal space, so that cloth and thread such as hemp are entangled with it, so strength is increased The method of scraping the surface of the tread is to scrape it with a rotating, very fine file or various methods. Drop the shavings etc. down, hit the water against the shaving area and let the shavings etc. flow together or blow down the wind and drop the shavings etc. down,
Only the surface of the tread is scraped, and if the surface of the tread is clear in a number of extremely small spaces (holes), it is not necessary to scrape. As for the jagged miniature hole, a hole of about 10 μm may be formed by thermal kneading, but a miniature hole is formed using laser light.
A laser that emits a lot of light with a laser emitter is condensed with a lens or a surface mirror at a high density, but it is made by penetrating a knurled hole in a ceramic or iron plate in a place where it has not yet been condensed. [This can be done manually.] Place the laser beam in the middle of focusing, the laser passes through the jagged shape, the laser becomes a jagged shape and condenses to a minimum, and it is a thin fiber Form a hole that can be as small as 1 μm in the shape of a jagged hole as a material for the part to be poured out of rubber.
Place a ceramic or iron plate penetrated in a jagged shape in front of the lens that condenses the laser, and pass a lot of emitted laser light through the ceramic or iron plate penetrated in a jagged shape to remain in a jagged shape Condensed light through a lens to create holes between very small holes.
