Description

Description: TECHNICAL FIELD The present invention relates to a method for manufacturing a hot carpet, the object of which is to maintain a raised state of piles, cilia, etc. on the surface of the epidermis, and a heater wire appearing on the epidermis surface. The object of the present invention is to provide a method for manufacturing a hot carpet that makes it possible to process a hot carpet having a good appearance by making the ridges caused by the ridges inconspicuous.

(Prior Art) Conventionally, a hot carpet is laminated by a press machine.

(See FIG. 4 (A)) In this press device (a), the base cloth (b) shown in FIG. 3 is used.
A hot carpet unprocessed product (f) comprising a heater wire (d) and an uncured adhesive layer (e) sandwiched between a skin and a skin (c) is heated and pressed for a certain period of time, and the unprocessed product The adhesive layer (e) of the product (f) is cured to bond the base cloth (b) and the skin (c).

(Problems to be Solved by the Invention) However, in the method using such a pressing device (a), heat transfer from the pressing device (a) to the adhesive layer (e) is caused by the base cloth (b) and the skin (c). Since the adhesive layer (e) is heated in a bad manner because it is performed indirectly through the adhesive, it is necessary to press the adhesive layer at a high temperature for a relatively long time. As shown in FIG. (C) The raised pile (g) such as piles and cilia on the surface is laid down and does not restore to the standing state even after the heat treatment,
There was a problem of impairing the appearance of the hot carpet.

Furthermore, in the method using such a press device (a),
Since the unprocessed product (f) is clamped to a uniform thickness, the sandwiching portion (h) between the base cloth (b) and the skin (c) sandwiching the heater wire (d) between the heater wire (d). ) Is pressed more strongly than the other parts by the amount of the space between them, and completely adheres to the peripheral side surface of the heater wire (d). After processing, it tends to stand out with a large curvature along the peripheral side surface of the heater wire (d). As described above, there is a problem that a local bulge is generated and the appearance of the hot carpet is impaired.

In view of the above circumstances, the industry maintains the raised state of piles, cilia, etc. on the surface of the epidermis, and the protrusion of the heater wire on the surface of the epidermis is less noticeable, and the processing of hot carpet with good appearance is reliable. It was desired to create a hot carpet manufacturing method that can be applied to

As shown in the figure, put the heater wire (d) on the base cloth (b),
An uncured adhesive layer (e) and a skin (c) were sequentially laminated on this to obtain a hot carpet unprocessed product (f).

In the second step of the present invention, the unprocessed hot carpet is clamped and moved by a pair of upper and lower mesh belts that move in the longitudinal direction of the casing in a horizontal type casing formed in a long tubular shape. At the same time as the second step, as a third step, countercurrent warm air circulating in the upper and lower spaces is blown onto the upper and lower mesh belts to cure the adhesive and bond the base cloth and the outer skin. Further, in the invention of claim 2, the skin of the hot carpet is humidified as a fourth step after the third step.

In FIG. 1, (1) is a manufacturing apparatus capable of carrying out the second to fourth steps of the present invention. The unprocessed hot carpet (f) manufactured in the first step is provided with a mesh belt (3),
While being sandwiched between (8), the adhesive layer (e) is cured with warm air to bond the base cloth (b) and the skin (c). Furthermore, the device (19) for humidifying the skin (c) of the hot carpet located at the terminal end humidifies the skin (c), thereby completely restoring the standing state of the skin (c) which has been slightly laid down.

 An example of the second step will be described below.

In FIG. 1, (2) is a casing, which is formed in a long tubular shape and is installed horizontally.

(3) is an endless lower mesh belt, which is formed in a mesh shape with a stainless wire or the like and has a felt (4) on the surface.

(6) is rotatably suspended, and is horizontally guided by the lower roller (7) in the casing (2), and the unprocessed product (f) is placed on the casing (2) in the longitudinal direction. To move.

(8) is an endless upper mesh belt, which is formed of polyester fiber in a mesh shape and whose surface is subjected to Teflon processing, and which has a drum (9) at the beginning of the casing (2) and a middle portion of the casing (2). The drum (10) is rotatably suspended, and is horizontally guided in the casing (2) by the upper roller (11) and is opposed to the lower mesh belt (3) in the casing (2). Belt (3)
The unprocessed product (f) placed on the upper part is pressed from the upper part, and the unprocessed product (f) is clamped between the lower mesh belt (3) and moved along the longitudinal direction of the casing (2).

Reference numeral (11) is an upper roller, and reference numeral (7) is a lower roller, both of which are installed at a fixed interval in the longitudinal direction of the casing (2) and are opposed to each other.
These allow the unprocessed product (f) which is clamped and moved between the lower mesh belt (3) and the upper mesh belt (8) to be passed while being pressed from above and below.

In the case of the above-mentioned constitution, the adhesive layer (e) during curing and curing is formed in each tissue of the base cloth (b) and the epidermis (c) by the sandwiching pressure of the upper and lower rollers (11), (7). It is more preferable because it penetrates to obtain an anchor effect.

In this device, the upper roller (11) is arranged only from the starting end to the middle of the casing (2) on which the upper mesh belt (8) is installed, and is arranged after the middle. It has not been.

The second step in the present invention is carried out, for example, by the apparatus as described above. According to this second step, since the adhesive layer is continuously cured and cured, it is not necessary to press an unprocessed product under a high temperature condition for a long time as in a conventional pressing device, and therefore, a series of operations can be performed in a relatively short time. Since the process is completed, it can be manufactured extremely efficiently.

In the present invention, in the third step, countercurrent warm air that circulates in the upper and lower spaces toward the upper and lower mesh belts is generated to cure the adhesive and bond the base cloth and the outer skin. An example of the third step will be described below.

In FIG. 1, (12) is a plurality of hot air generators,
The casings (2) are arranged at regular intervals in the longitudinal direction.

Countercurrent warm air (18) that circulates in the upper and lower spaces toward the upper mesh belt (8) and the lower mesh belt (3) is generated by the upper and lower warm air generators (12), respectively, and An adhesive layer (of an unprocessed product (f) that is sandwiched between the upper mesh belt (8) and the lower mesh belt (3) and moves in the casing (2) in the longitudinal direction of the casing (2). The e) is cured by the heat of the countercurrent warm air (18) to bond the base cloth (b) and the skin (c) to each other.

The counterflow hot air (18) whose temperature has been lowered by heating the unprocessed product (f) is recovered from the intake port (14) and reheated by the heater (15), and the same hot air discharge port (16) Is released from and repeats this circulation cycle.

Even if the intake port (14) of the manufacturing apparatus (1) is formed above or below the upper and lower mesh belts (8) and (3) as well as the warm air discharge port (16) (Fig. 1 (C)). (Reference) The hot carpet manufacturing method of this invention can be implemented.

Further, the counterflow warm air (18) collected from the intake port (14) is reheated by the heater (15), and the warm air discharge port (16) in the opposite space (from the upper space to the lower space or vice versa) is different. Even if it is emitted from the hot air discharge port (16) in the next step (see FIG. 1 (F)) The hot carpet manufacturing method of the present invention can be carried out.

Since the hot air generator can have a structure that sequentially sucks the hot air in the adjacent rooms, the hot carpet manufacturing apparatus described above is excellent in thermal efficiency.

The third step in the present invention is carried out by the apparatus as described above, for example. According to the second step and the third step of the present invention, the epidermis is pressed against the base cloth and the heater wire supported by the lower mesh belt by the wind pressure of warm air at a uniform pressure,
Since the base cloth sandwiching the heater wire and the sandwiching portion of the outer skin are smoothly bulged with a small curvature, the bulge due to the heater wire is less noticeable and a hot carpet having a good appearance can be processed.

In addition, since the hot air indirectly heats the adhesive layer to cure and cure it, the adhesive layer is in a good heating state, and the unprocessed product is exposed to high temperature for a long time as when using a conventional press machine. There is no need to press under conditions, and piles on the surface of the epidermis, raised hairs such as cilia do not fall over, and in this respect also, the appearance of the hot carpet can be kept good.

In the present invention, the skin of the hot carpet is humidified as the fourth step after the third step. An example of the fourth step will be described below.

In FIG. 1, (19) is a device for humidifying the skin (c). The humidifying device (19) may be provided at the end of the casing (2).

The fourth step of the present invention can be carried out, for example, by the apparatus as described above. By the fourth step, the standing state of the epidermis (c) which is slightly laid down in the second step and the third step can be completely restored.

Next, the operation of the hot carpet manufacturing method according to the embodiment of the present invention will be described.

In this embodiment, the unprocessed hot carpet product (f) with the skin (c) facing upward is sandwiched between the upper mesh belt (8) and the lower mesh belt (3) so that the inside of the casing (2) is closed. While moving, warm air (18) is generated by the warm air generator (12).

According to this method, since the adhesive layer (e) is indirectly heated by the warm air (18) to cure and cure the adhesive layer (e), most of the piles (g) such as piles and cilia on the surface of the epidermis (c) are cured. The warm air (18) hits the skin (c) of the unprocessed product (f) from above without laying down, and the wind pressure causes the skin (c) to be sandwiched by the lower mesh belt (8) ( b) and the heater wire (d) are pressed by a uniform pressure, and as shown in FIG. 2, a sandwiching portion (h) between the base cloth (b) and the outer skin (c) sandwiching the heater wire (d) therebetween. Bends smoothly with a small curvature.

Further, the adhesive layer (e) during curing and hardening enters the tissues of the base cloth (b) and the epidermis (c) by the sandwiching pressure of the upper and lower rollers (11) and (7) to obtain an anchor effect.

In addition, hot air (18) is applied to the unprocessed hot carpet (f).
When the epidermis (c) is humidified after spraying, the standing state of the epidermis (c) which has been slightly laid down can be completely restored.

(Effects of the Invention) The present invention has a first step in which a heater wire is placed on a base cloth, and an uncured adhesive layer and a skin are sequentially laminated on the heater wire to form a hot carpet unprocessed product, and a long tubular shape is formed. A second step of sandwiching and moving the unprocessed hot carpet product between a pair of upper and lower mesh belts that move in the longitudinal direction of the formed horizontal casing, and at the same time as the second step, in the upper and lower spaces, respectively. A method for producing a hot carpet, comprising a third step of curing an adhesive by blowing a circulating countercurrent hot air onto the upper and lower mesh belts to bond and process the base cloth and the outer skin, And a fourth step of humidifying the surface skin of the hot carpet after the third step, in addition to the first to third steps described in claim 1, and a method for manufacturing a hot carpet. It has the following effects.

When a hot carpet is manufactured by the hot carpet manufacturing method of the present invention, the skin is pressed against the base cloth and the heater wire supported by the lower mesh belt with a uniform pressure by the warm air, and the heater wire is sandwiched between them. Since the sandwiching portion between the base cloth and the outer skin is smoothly bulged with a small curvature, the bulge due to the heater wire is inconspicuous and the hot carpet has a good appearance.

In addition, since the hot air indirectly heats the adhesive layer to cure and cure it, the adhesive layer is in a good heating state, and the unprocessed product is subjected to a high temperature condition for a long time like a conventional press machine. Since there is no need to press with, the piles on the surface of the epidermis, raised hairs such as cilia do not fall over, and in this respect also, the appearance of the hot carpet can be kept good.

Further, the unprocessed hot carpet is sandwiched by a pair of upper and lower mesh belts and moved in the longitudinal direction in the casing, whereby the adhesive layer is continuously cured and cured. As described above, it is not necessary to press the uncured product under high temperature conditions for a long time, and therefore a series of steps are completed in a relatively short time, so that the product can be manufactured extremely efficiently.

In addition, when the epidermis is humidified as the fourth step, the raised and slightly raised epidermis of the epidermis is surely obtained, and a hot carpet having a soft and soft texture can be obtained.
