Description

An apparatus for fabricating of angular velcro tapes

The present invention relates to an apparatus for manufacturing a folding type velcro tape, and more particularly, to an apparatus for manufacturing a folding type velcro tape provided on the side of the interior pad for coupling between an interior pad and a cover skin constituting a vehicle seat.

In general, a vehicle seat includes a built-in pad filling the inner space, and an outer cover skin surrounding the built-in pad.

In vehicle seats having such a configuration, a velcro tape is often used as a coupling means between the cover skin and the built-in pad in order to prevent wrinkles or bending when the cover skin is pushed to one side.

1 shows an example of a built-in pad and a cover skin. Referring to this, Velcro tapes are provided on the built-in pad side, and counter parts attached to the Velcro tapes are provided on the inner surface of the cover skin. Thus, when assembling the cover skin on the built-in pad, the Velcro tapes and the counter parts are coupled to each other, thereby preventing problems such as wrinkles or bending of the cover skin.

2 shows examples of conventionally used Velcro tapes. As shown here, a straight velcro tape (1) and a curved velcro tape (3) are commonly used. Depending on the sheet design structure, only one type of these tapes 1 and 3 may be used or may be used in combination, but they are often used in combination.

The top surface of the straight velcro tape (1) is provided with a protection tip (2) made of a sponge material along the edge. On the other hand, a protection film (4) covering the entire upper surface of the curved Velcro tape (1) is provided.

3, the built-in pad is formed by inserting the above-described Velcro tapes 1 and 3 into the mold 7, injecting the foaming solution into the mold 7 with the injector 8, and then foaming it. . In this process, the aforementioned protection tip (2) and protection film (4) serves to prevent the foaming liquid from penetrating into the bonding portion (the portion shown in green) of the Velcro tapes (1, 3).

Referring to FIG. 4 , the built-in pad molded in this way has a form in which the Velcro tapes 1 and 3 that were disposed as inserts in the mold 7 are integrally combined. Then, after taking out the built-in pad from the mold 7, with respect to the curved Velcro tape 3, the protection film 4 (refer to FIG. 2) which covered the joint portion (the part shown in green) that was entirely covered by the post-work should be performed.

As such, in the case of the curved velcro tape (3), there is a disadvantage in that a post-operation is required to separate the protection film (4) after molding the built-in pad.

An object of the present invention is to provide an automated device for the production of a velcro tape that does not require a protection film to replace the conventional curved velcro tape.

In order to achieve the above object, the present invention provides a bending type velcro tape manufacturing apparatus 100 for processing a straight velcro tape into a bending type velcro tape, a rotating plate 120; and a plurality of working plates 130 mounted on the rotating plate 120 along its circumferential direction, wherein one fold-type velcro tape is produced for each rotation of the rotating plate 120 . provide the device.
