The present invention relates to a device and a method for manufacturing a pile band (one side mohair) inserted into a window frame edge of a retractable window for the purpose of windproof, soundproof, waterproof, insect repellent, etc. It is about improvement of a method.

In the patent application, the baseband is tightly supplied from the side of the pile yarn wound tightly on the endless steel band, and then subjected to an ultrasonic bonding device so that the side of the pile yarn is welded to the baseband. Many problems are exposed:

◎ Because it is manufactured through the welding process, it is possible to generate harmful gases of molten sand, which hinders the working environment and also causes occupational diseases.

◎ It is hard to be hardened during solidification of welding area, so it is less flexible and easy to break, which lowers the durability of the product.

◎ If the temperature control of the ultrasonic bonding device is not appropriate, the adhesion of the pile is insufficient and it is easily detached or the pile is excessively melted, which leads to a high rate of product defects.

◎ Expensive ultrasonic bonding device is necessary to expose the problem of increased equipment cost.

The present invention has been devised to solve the above problems in the above-mentioned filings, and immediately before the pile yarn is wound, the rod-shaped core material is supplied in close contact with both sides of the endless steel band, and then the pile yarn is simultaneously wrapped around both core materials. At the same time, the pile band is supplied to the outer surface of the two cores in which the pile yarns are wound, and the base band is formed so that the two cores are interposed so that the pile band is physically fitted without the need for a separate ultrasonic bonding device. Referring to the configuration of the present invention and its manufacturing method in detail based on the accompanying drawings to be manufactured as follows.

Rotating cylinder (1) having an inlet (2) and outlet (3) on both sides as a means for winding the pile yarn is rotatably installed in the body (2), the pulley (4) on the inlet side of the rotary cylinder (1) By rotating the rotating cylinder (1) by the motor (M) and the anti-slip uneven portion 6 and the core guide groove (7) is formed at both ends and rotated by a plurality of guide rollers (R) The endless steel band (5) to be penetrated through the inlet and outlet (2) (3) of the rotating cylinder (1) and the pile yarn bobbin shaft (8) is provided inside the rotating cylinder (1) and the outlet of the rotating cylinder (1) On the side of the (3) side of the pile yarns (9) is provided, the inside of the yarns (9) by the guide roller (7 ') so that the core material 10 is in close contact with the core guide groove (7) and the outlet (3) The base band 13, which is provided with a pair of base band guide rollers 11 and 12, is formed at the outside of the guide plate so that the base band 13 having the elastic clamping piece 13 'is integrally fitted to the two cores 10. In the upper and lower front of the guide roller 12, a pile cutter consisting of the rotary blades 14, 14 'and the fixed blades 15, 15' is installed and the inlet side gas 2 of the rotary cylinder 1 is provided. On both sides of the outlet, the upper and lower steel wires 16 and 16 'which raise the pile yarn in the endless steel band 5 are fixedly installed to constitute the apparatus of the present invention.

In the figure, reference numeral 20 denotes a pile bobbin, 21 denotes a pile yarn, and (P) shows a pile band manufactured by the present invention device.

Hereinafter, the operational effects of the pile band manufactured by the apparatus of the present invention and the apparatus will be described.

First, the bobbin 20 of the pile yarn 21 is inserted into the pile yarn bobbin shaft 8 installed inside the rotary cylinder 1, and the pile yarn 21 is piled yarn provided on the outlet side of the rotary cylinder 1. After observing the drawing (9), the motor (M) is driven to rotate the rotating cylinder (1).

In addition, the endless steel band (5) is also rotated by the guide roller (R) and passes through the inside of the rotating cylinder (1) at this time the endless steel band (5) in the core guide groove (7) at both ends and the Similarly, the core material 10 is supplied in close contact with the guide roller 7 '.

At this time, due to the rotation of the rotating cylinder 1, the pile yarn 21 is wound so as to surround both core material 10 and the steel wire 16, 16 'like the virtual line in FIG.

At this time, the pile yarn 21 wound up is spaced apart from the bottom surface of the endless steel band 5 by a predetermined distance by the steel wires 16 and 16 'and the pile yarn 21 is prevented by the non-slip unevenness 6. It is wound up uniformly without being pulled from the core material 10.

In this way, when the two cores 10 on which the pile yarn 21 is wound are forwarded and transferred forward, PP (polypropylene) base band 13 is supplied to the side of the core 10 at both sides as shown in FIG. When the elastic clamping piece 13 'is pushed by the guide roller 11 and opens, the core member 10 is buried and retracted by its elasticity to reach the pile cutter in the coupled state as shown in FIG. 15 ') by the rotary wire (14, 14') while entering the vertical space formed between the pile yarn 21 and the endless steel band (5) by the steel wire (16, 16 '). The yarn 21 is a two-ply pile band (P) is produced by cutting the upper and lower parts.

The pile band P manufactured as described above has a pile band P in a state in which a pile yarn 21 is sandwiched between the core 10 and the elastic clamping piece 13 which bites it as shown in FIG. It is composed.

The present invention by the operation and the manufacturing method of the present invention as described above is to avoid the structural deformation of the molten and to constitute the pile band only in the simple fitting form, so that almost no defect rate of the product and also the durability of the product It can improve and at the same time reduce the equipment cost of the manufacturing equipment, it is very competitive and there is a great effect such as not to emit harmful substances to improve the working environment.
