Description

[Detailed description of the invention] [Name of invention] Apparatus and method for longitudinal compression treatment of strip material (Field of the Invention) The present invention applies to knit and woven fibers, paper, plastic films, and e.g. Formed into a web by air-laying or wet-laying the fibers. Longitudinal lengths of highly flexible strip materials such as so-called "non-woven fibers" made of natural or synthetic materials. Related to directional compression processing technology.

(Background of the invention) In the laboratory on which this invention is based, the longitudinal compressive force is highly flexible. It took many years to develop a method for treating the web, which is applied in-plane to the web material. this research U.S. Pat. No. 2,765,513 and U.S. Pat. No. 65,514 and No. 3,260,77 regarding bladed microcreeper. No. 8 and No. 3,426,405, relating to bladeless microcleavers. No. 3,810,280, No. 3,869,768 and No. 3,975, No. 806, and No. 4,142,278 regarding the 20-La type microcleaver. Many inventions were created, including the number. Most of these inventions use low friction surfaces. drive the untreated web in the longitudinal direction and press it against a rotating drive roller to A force is applied to the moving web in the vicinity that resists its movement. Drive The state of antagonism between the power and resistance forces is such that while the material remains constrained in the plane direction, Desirable physical changes in the web material, such as in its bulk, thickness and stretchability cause an increase.

In the case of fibers and fibrous materials, the web folds or crepes itself. Crimp of thin fibers, especially on the sides, which do not form, but constitute a yarn, i.e., a single thread of cloth (ripple of cloth) can be longitudinally compressed in its own plane, resulting in "micro-creeping").

For hard thin sheets such as paper or plastic film In this case, the longitudinal compression process produces almost no visible irregularities in the web as a whole. Crepes (“micro-creeping” of the web) may form; The overall appearance of the surface of the board is consistent without any rough crepes or folds on the surface. It naturally exhibits a smooth state. However, if a coarse crepe is desired, this This can be achieved by appropriately enlarging the treatment holes.

In many cases, some or all of the compressed state along the length of the web is converted into a tensile operation. Therefore, after removal, the web retains the desired quality caused by longitudinal processing. It will be done.

In certain cases, this process can increase the flexibility of the web. , increasing its covering effect and opacity, making the surface condition of the web even more attractive. to provide shrink-proof properties to the web, to provide a decorative effect to the web, or to The composition of the blocks can be more tightly intertwined in an effective manner. Stretching of long paper material It can also improve its breakage resistance.

For many materials, the machines and processes found to be most promising are Negative retarder shown in expired U.S. Patent No. 3,260,778 /A flexible retarder device is used. The web is driven by a stationary surface (“-order” surface) Pressed against the roll to provide a drive area, with a substantial The stationary surface downstream of the drive region (the "potential-negative retarder" surface) is set at an angle of The primary web is warped at a substantial angle from its path on the roll. The web extends downstream from the roll face to the angle of the negative retarder. A thin and highly flexible confluence surface (a ``flexible retarder'') surface) produces surface alignment with the web. Using a single roll form like this This allows for the handling of very thin webs and the application of large pressures over short distances. A very small processing cavity can be secured to allow the addition of

This negative retarder/flexible retarder device seeks to achieve a balance between competing requirements. do. The substantial angle of the negative retarder exerts an effective longitudinal compressive force on the web. Allows you to add On the other hand, flexible retarders also allow the web to When maintaining the required lateral restraint of the web while changing the degree of The web is positioned below the tip of the blade of the negative retarder. It flexes to prevent it from getting caught.

Some commercially available devices constructed according to U.S. Pat. No. 3,260,778 include The angle of tarda is approximately 38 degrees to the tangent to the roll and corresponds to this angle. The flexible retarder is made of a thin sheet of blued Swedish steel (e.g. with a thickness of approx. ．． 05 to 0.15++++s (0,002 to o, oos inches)) Ta.

Using this principle, the web below the blade tip of a negative retarder is A machine that further seeks to prevent snagging is Packard's U.S. Pat. No. 4,090. , No. 385. In the case of this machine, a roll with grooves is provided. , the leading edge of the negative retarder has a spaced apart groove inserted into the lower groove on the entire surface of the roll. An engagement finger is provided. In such a configuration, driving conditions are low. Because the grooved part of the roll is different from the non-grooved part, the processing variation in the width direction of the roll is There is a risk that this may occur.

Longitudinal compression of the web using a negative retarder/flexible retarder device Processing is often slow or limited to a limited range of starting materials and products. and requires considerable operator proficiency in handling changing manufacturing conditions. However, it has been successful in some commercial applications.

Particularly commercial There remain many examples in the thin web area where this has not been done.

can affect the opposing driving and resisting forces of the longitudinal compression process and Examples of variable production conditions that can lead to fixed or continued operational difficulties include: There is a matter mentioned below. For example, due to fatigue or the presence of foreign matter on the drive roll surface. Changes in web gripping characteristics of the drive roll; changes in raw web thickness and drive roll Changes in the acting force that presses the limiting surface and web against the web or the shape of the limiting surface Change in pressure of the web against the drive roll due to changes in condition: untreated web Change in feed tension applied to the web as it enters the processing stage: The hardness or flexibility of the untreated web can be affected by changes in web moisture or temperature. changes in the depth of the resistance path that the web passes; e.g. changes in dimensions or speed. changes in other resistance properties due to changes in the susceptibility of the web to resistance effects, etc.

During manufacturing, it is also necessary to maintain precise alignment of the combined retarder. Ru. Such alignment measures are difficult to maintain, and in some applications even slight inconsistencies may dimensional changes in the processing cavity resulting from undesirable non-uniform product There is a risk. For this reason, rigid angle retarders/flexible retarders are preferred. Although it has been considered necessary to have a difficult and expensive installation, problems may still arise. There is.

Furthermore, during use of the corner retarder/flexible retarder device for production, the flexible retarder It is possible to match the retarder to the combined retarder and apply the appropriate elastic pressure to it. It was important to properly select and maintain a flexible retarder. flexible reta If the pressure applied by the carder is too low (this may occur due to thickness selection) (which may occur due to incorrect setting or fatigue), the required delicate microcrystalline This will prevent you from getting the pinging effect. However, the amount of change in the flexible retarder is small. If not, excessive pressure may be created by pressing the material under the leading edge of the combined retarder. A point is quickly reached where it becomes stuck or breaks. Improper alignment measures are There is a risk that uneven pressure may be applied to the material, resulting in uneven processing. will bring the product. Also, perhaps most undesirably, visible bending of the retarder (e.g., repeated deflection during adjustment or use, or improper Severe bending due to positive adjustment) can permanently deform the visibility retarder and cause permanent “distortion”. causing stress and reducing its pressure and elasticity, skipping or terminating the processing step. may occur at the same time.

Due to changing production conditions during use of the square retarder/flexible retarder device, minor wear and tear may occur. The processing point of the material on the primary surface of the scraping is likely to move back and forth, affecting the quality of processing. shall be. Therefore, it is necessary to make adjustments before and after the negative plane.

The job of the personnel operating the machine is to establish the initial operating coordination of the process and to monitor all production conditions. During operation, changes in conditions should be monitored and compensation adjustments should be made. The aim was to try to match these fluctuations by In fact, one or more changes The production conditions that can be operated may change simultaneously, and the machine operator may not be able to respond. This results in complex behavior that requires

Uniform processing is often important in commercialized microcreeping operations This is a major requirement, and if adjustments are not made at the appropriate time, the product may be damaged. simple As an example, in the manufacture of disposable medical products such as surgical gowns, many A large amount of fabric material is micro-creeped so that small pieces are cut at the same time. Stack them up. If the material is not uniform and therefore does not overlap flatly, the cutting will not be possible. This results in a uniform and undesirable article.

Similarly, kraft vapor, which is used as a partition between stacked steel plates, must be uniform to keep the plate flat on the pallet.

In other cases, the original thickness of the fill is on the order of about 0.025 mm (0,001 inch). In order to soften the filler material, it is necessary to carry out processing at very high speeds. , this is suitable for corner retarder/flexible retarder equipment or for the web being processed. May produce excessive heat that cannot be tolerated.

An important object of the invention is to take advantage of the bladed configuration of a single roll. For longitudinal compression processing of the web that reduces or eliminates various important features of processing. The aim is to provide new methods for Another purpose is to accommodate a wide range of materials and thicknesses. Obtain uniform, high-quality processed web products, especially in very thin webs It is about making things possible. Another purpose is to perform a wide variety of operations even at high speeds. The purpose of this invention is to provide a method that allows the use of relatively heavy and long-life elements that can Ru. Another object is to provide a simple machine of improved construction. Other objects of the invention achieves improvements in manufacturing and energy efficiency, and introduces new technologies for web materials. The goal is to achieve special processing. One particular object of the invention is to use e.g. An object of the present invention is to provide an improved method for shrink-proofing webs, which are thick diagonally woven fabrics such as denim.

(Summary of the invention) The present invention provides microcreepy effects on the running length of the web by applying extrusion resistance force. Single roll machine with blades (and using this machine) method), in which: (a) ° the wood machine has a tangential extrusion action; (b) extrusion; The elastic self-adjusting action of the holes defines one of the web contact surfaces that form the extrusion holes. Therefore, the plate member is elastically pressed against the drive meshing part in the extending direction. This is achieved by using a plate-shaped blade member parallel to the roll.

In a preferred embodiment, the web contacting surface defining the other side of the extrusion hole is - This second web contact surface is a cantilevered integral continuous part of the pressure surface, and this second web contact surface is Under processing conditions for a curved shape in the opposite direction to that of the surface, the radius is about the same as the radius of the roll. It is desirable to be able to limit the deflection to the curvature of the first web contact. The surface is movable while remaining parallel to its original surface in the processing cavity. Gradually changes the form of the The process cavity is changed by rotating the process cavity, and by slightly pivoting in the plane. Slightly changes the alignment of the upstream edge of the surface to the surface to ensure a positive final drive The angle of the axis of the extruded hole with respect to the tangent to the roll at the point is less than 20° The height of the processing cavity is such that both the roll and the polymerizing surface have a gradually expanding curve. The resulting rate increases gradually in the direction of web movement.

The method and machine described above may be used in various ways as described below in the section entitled "Operation". has advantages.

In particular, tangential extrusion as described below is unique to the type of process being converted. Apply compressive force to the web to avoid problems. This tangential extrusion The configuration and force of This actually allows for automatic adjustment of the processing cavity morphology or reduce the risk of improper processing forces or the severity of adjustment of this member. It removes it.

Precisely limiting the extrusion path variation from the exact tangential direction is a reasonable variable. depends on the total combination of factors and desired results. while maintaining the desired results of the invention. In some cases, an angle of 20° is permissible. Approximately 0.25ma+ (0,010i When using primary or hardened members of blued steel, this angle is typically 20 It is desirable not to exceed °.

These and other features and advantages of the invention can be found in the drawings and in the claims. from the following detailed description of preferred embodiments.

(structure) In FIGS. 1 to 3, the roll 10 is rotatably supported and is rotated by a motor. Driven in the direction of arrow A by a standard drive mechanism such as a vane or belt drive. be moved. Immediately above the roll 10 is supported by a vertically movable shoe 16. There is a pressure member 20 extending outwardly from the shoe 16 in a cantilevered manner. This pressure member support Vertical movement of the holding assembly is controlled by a pressure cylinder (not shown).

The pressure member 20 is oriented at the shoe 16 at an angle to the horizontal, so that Edges 18 of the cantilevered portions of member 20 are pressed against the surface of roll 10.

- The mounting member 14 is mounted on a steel plate cantilevered forward from the bracket 22. Neka growls. - the forming member 14 extends over the roll 10 and is attached to the edge 18 of the pressure member 20; The meshing area (between the component 14 and the roll 10) is pressed against the roll by form the nearest area). - the component 14 extends downstream from this mating region; blade 24 (in its plane advanced by an air cylinder as described below); There is a slight overlap on the upstream edge of the Ru. - the component 14 has a slightly limited bending capacity and is Compared to the flexible retarders used in negative retarder type machines such as those mentioned in Sec. It is thick and has high rigidity. The component has a thickness of at least about 0.25 mm. mm (0,010 inch) blue-tinted steel with a smooth surface in the meshing area. desirable.

In the illustrated embodiment, the roll 10 is approximately 12 inches long. It has a diameter.

The extrusion holes located downstream from the interlocking area are located on the upper surface of the web in the primary member 1. The extension of the lower surface 28 of is defined by surface 16 of door member 24 .

As shown in FIGS. 1 and 2, the pressure of the pressure member 20 on the primary member 14 is force, and compression below which fills the processing cavity and exerts an upward pressure The action of the downstream portion of the primary member on the formed web is caused by the action of the downstream portion of the primary member 14. The roll 10 is curved slightly, thereby bending it away from the surface of the roll 10. especially, - this part of the component 14 has a mating area with a radius of the order of the radius of the roll lO; It can have curvature in the area immediately downstream.

As best shown in FIGS. 2 and 3, member 24 has a fastener extending therethrough. It has a front adjustment slot 36 and a rear adjustment slot 38 for receiving the fixed port 41. This is a plate-shaped blade member supported on both sides by vertical plate members 34.

On both sides of the downstream edge of the blade 24 there is a There is a bracket 32 that is coupled together.

By applying air pressure to these air cylinders 30, the blocks inside the holder are The blade 24 is elastically pressed to the left with respect to its support 34 in FIG. . The state of application of elastic pressure in the direction of the plane of the blade is shown in FIG. is schematically indicated by an arrow and a spring S.

The posture of the extrusion hole is determined by the angle of the tip of the upper surface 26 of the plate member 24 (roll I The point that is the final reliable drive application point due to the area of engagement between O and the primary member 14 measured relative to the tangent to the roll at P).

By moving the pivot plate 34 (see Figure 1a) or by moving the blade 24 ( By chamfering the ends of the roll 1 at the face 26 and point P (see FIG. 1b), The angle between the tangent to 0 can be varied. Limiting this angle Therefore, the axis X of the extrusion hole is approximately parallel to the tangent to the roll, and It can be maintained in line with the path of the web that is being fed further forward. Special The angle to be restricted is generally between 0 and 15°, with 20° being a wide range of cases. is the upper limit that can be used to obtain the best results.

The shape of the processing cavity located between the engagement region and the extrusion hole is such that the blade further controlled by an air cylinder 30 which elastically presses the mating area against the mating area. be able to. Therefore, during start-up, a deposit of compacted material is formed. Before, the tip of this blade is driven well below the primary member towards the feed side of its running position. as the process moves and then deposits form and the pressure in the process cavity increases. the thickness and nature of the web and the air pressure applied to the air cylinder 30; automatically until reaching a stable elastically maintained running position determined by respond by moving backwards.

In Figure 1a, temperatures within the range of approximately 150-175°C (below 300-350°C) A very effective shrinkage-permitting form of cotton denim fabric in the dry state at temperature is shown. has been done.

In this case, the compression process is carried out in the process cavity before the tangential extrusion hole TEO. however, this action is reinforced by the additional frictional action created by member 50. be converted into This element, made of spring steel, provides support between the component and the element 15 above it. held. This member has a 300 to 350 rms polymerization rate on the exiting fabric. Polished with tungsten carbide plasma coating in range of roughness. There is a wide portion 50 that provides a rubbing surface.

This component provides a soft "buttery" feel while adding a high level of Helps ensure smooth movement of the fabric through the machine despite the compressive forces of the machine. has the desired effect on the surface of the fabric.

In Figure 1b, the thickness is approximately 0.025+am while maintaining the strength of the material. (0,001 inch) of paper filling in dry state to produce almost foamed elastic material. A configuration is shown that makes it possible to produce materials with high elongation.

In this configuration, the pressure member 14 is approximately 5.1 mm from the pressure line at the corner 18 of the pressure section. mm (0.2 inches), and the angle of the face 26 of the blade 24 is The tip of the blade below the primary member under running conditions, set between I2 and 15° The cutting distance U of the part is about 1.27 ma+ (0.05 inch).

As can be seen from the figure, the axis X of the extruded hole TEO in the tangential direction is in contact with the drive roll. It remains approximately parallel to the line.

Is the rough sanding of the corners caused by pinking, serrations, or thinning of the tips? Various forms of extension of the primary member, such as those resulting from For example, about 5.1 mm (0,020 in f) (r) thick This makes it possible to use even thicker primary members.

(Function of this device) When the web 12 moves with the surface of the roll 10, this web moves with the roll surface and - The engagement established by the edge 18 of the pressure member 20 acting through the forming member 14 Encounter a false area. This area of engagement is the final point at which the web is reliably advanced. a driving action, indicated by an arrow, parallel to the tangent to said roll at point P; Empower. Downstream from this mating area, the web is located at the bottom of the primary member 14. defined by an extension of surface 28 and an initial portion of upper surface 26 of blade member 24 encountering the extrusion hole (the blade member 24 is moved by the air pressure of the air cylinder 30) (elastically pressed into place). In this way, the web is aligned with the axis of the extrusion hole The extrusion indicated by the arrow R, which is approximately directly opposed to the driving force due to the orientation of subject to resistance.

The portion of the primary member 14 shown in FIG. 1 is very short, and the acting force of the pressure member 20 is Effectively, press the cantilevered portion of the member 14 toward the tip of the blade 24. As you can see, Figure 1 has been enlarged. The blade 24 is perpendicular to that surface. Since it is fixed in the direction of an angle, it is possible to obtain the required amount of acting force R. (as adjusted by the level of air pressure applied to the air cylinder 3o) eye). Because of the drag forces encountered by the web, the web will It is extruded at a speed significantly lower than its travel speed. In this way, the material that has received resistance A deposit of material fills the extrusion channel and is placed in front of the material driven forward by the interlocking region. resist progressive movement. If the web in this area is on its side (roll 10 and and primary member 14), this web extends longitudinally immediately after point P. However, the "-linear" elastic action of the blade member ensures uniformity of the action. This guarantees that

Compressing a web according to the illustrated arrangement has many advantages.

First, the overall direction of web movement does not need to be heavily deflected, so shearing The power consumption (which may result in uneven processing due to web thickness) is very low. It's over. The drag action is caused by a resistance to the web, without a sharp deflection in the direction of web movement. given by a symmetrical force of action.

Second, there is no need for large flexible members to restrain the web; Instead, all steel plate members that come into contact with the web in the compression ramp should be made to a considerable thickness. As a result, it can provide stability and long life. (- component member 14 is In conventional micro-creeping equipment, which requires bending at relatively sharp angles, (sufficiently stronger and thicker than in the case of flexible retarders). 14 fatigue is reduced and the equipment is protected from such fatigue or permanent bending results. The need for breakdowns or adjustments is reduced or avoided.

Third, related to the first and second advantages, familiarization during initial setup and operating This process can be carried out with almost no need for the operator's attention; very different characteristics with little or no change in machine adjustment. Changes between sexual webs are possible.

Fourth, because the component 14 is generally flat, the cooling component 14, as shown in FIG. It is practical to provide a cooling liquid on the upper surface of the member I4 and to introduce a cooling liquid to cool the member I4. Therefore, high-speed operation is possible.

Fifth, since the plane of the blade 24 is located approximately parallel to the driving direction, the structure and It has many advantages, such as easier adjustment. Direction perpendicular to the plane of the blade 24 The component of the force acting on the blade at It can move relatively freely in two types of motion within the plane of . one exercise type in which the blade is closer to the meshing area approximately in its own plane. Since the web moves far, the lateral edge of the face 26 of the blade 24 It is possible to maintain a state substantially perpendicular to the direction of movement. Nearby movements are processed Narrows the extrusion passage at a gentle and controllable rate while reducing the overall length of the cavity. Ru. The thinner the web and the finer the crepe required, the smaller the processing cavity. The length must be short and the elastic pressure that must be applied will usually be large. Bu Adjust the air pressure in both cylinders 30 to adjust the position of the blade member. . This type of small amount of motion can be caused by variations in web properties or drive roll speed. In response to changes, attachment of the blade member can occur automatically during operation due to the elasticity of the part. .

This is also a second type of movement by the blade 24 in the plane of the blade 24. includes a slight pivoting or self-aligning movement of the leading edge transverse to the direction of web travel. . Such movements do not require precise adjustment and can be controlled by the web thickness in the web width direction. This is desirable because it takes into account variations in the For example, if one side of the web If an abnormal thickness occurs in the physical cavity, one cylinder 30 and the opposite position The force acting on this side of blade 24 at It will be driven slightly backwards relative to the side. Such movement causes the cylinder 30 This can be achieved automatically as a result of a relatively small load on the cylinder allows it to respond to relatively small forces caused by fluctuations in the web. make it possible.

A relatively small load on the surface 26 in a direction perpendicular to said surface is approximately tangential to it. obtained as a result of the orientation of the

Some advantages of the present invention compared to the best conventional microcreeping devices In summary, the present invention enables the following: In other words, is it a pressure bar? There is no need to adjust the head back and forth to find the optimal amount of overhang of the plate-shaped member at the tip. Become.

A member that is relatively thick and has a relatively long life, that is, it can withstand high-speed operation. It becomes possible to use

the same despite variations in web processing conditions such as temperature, moisture, and plasticity. equipment that has a physical effect, thus reducing the fineness or coarseness of the processing required. These can be done without requiring any mechanical attention other than adjusting the blade position by Allows adjustment and optimization of variable factors.

In Figures 4 and 5, the bottom of the extrusion passage is located at finger 9B (only three are visible). A second aspect of the invention defined by member 124 having an upstream edge formed by An embodiment is shown. This finger defines an extrusion hole from the surface of the roll 10° Fits within the groove 99 on the roll to create a smooth transition to the lower surface 126 It has a size that

Fingers 98 permit pivoting movement of member 124 as described above and are provided on the sides of groove 99. It is narrower than the groove to avoid contact between the finger 98 and the groove. The groove 99 The depth is sufficient to create a gap between the land portion 97 of the groove and the finger 98. child As a result, the fingers are in wear-free engagement with the drive roll, and the fingers are The smooth sides of the web remain smooth, thereby avoiding web snags.

In other respects, the operation and construction of the machine of FIGS. 4-5 is similar to that of FIGS. 1-3. It is the same as that in the figure, and both sets of figures have corresponding reference numbers. Ru.

In the presently preferred embodiment, the surfaces defining the extrusion holes are polished and the operating speed It is effective when the resistance level is high or when the required level of resistance is low.

In other cases, one or both of these surfaces may be specially designed to produce the desired effect. can be processed. For example, where a frictional or fluffing effect is required. In some cases, tungsten steel is applied to metal surfaces to provide a surface with relatively high friction and long life. can be plasma coated with fine particles of carbon carbide.

In other embodiments, the front of each element of the machine including providing slots, wavy edges, etc. Special edge or surface shaping to create brisé stripes or other desired aesthetic and functional effects. can bring about great effects. These are our earlier patents mentioned at the beginning of the text. It is described in detail in .
