Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves sequentially cutting a long belt-shaped fabric such as a tape-shaped knitted fabric or a tape-shaped elastic fabric made of a woven fabric such as a rubber strip or a polyurethane elastic yarn to a predetermined size. The present invention relates to a manufacturing device that sews cut fabric into a circular shape.

Conventionally, this type of manufacturing equipment for circular fabrics has been manufactured using the 18th
As shown in the figure, there are configurations that have the gist of the configurations described in the following [I]' and [1m].

(I) A device (B') for supplying long strip-shaped fabric (al to the sewing table ill side) and a device (B') for feeding fabric (supplied fabric ia) to the sewing table ill side, which can freely clamp and release the tip of the fabric (i.e., the supplied fabric ia) from the rotation trap in the pinched state. The apparatus is equipped with an arm (50) for inverting the tip of the sewing machine presser foot (27) and a device (C') for cutting the fabric (81) that has been inverted once into a predetermined size from the tip.

[I[] A member (c) υ that can freely clamp and release the rear end of the cut fabric + 8) and that can move in the distance direction of the sewing table (11) and the sewing table (1) close to the sewing table (1) side. By moving, the rear end of the fabric (B1) clamped and held by the clamping member value υ is folded onto the sewing table (11), and by moving close to the m mating 111 side, the sewing machine presser foot (27
A member (mill) is provided for overlapping the leading end of the fabric (a) located on the sewing table Ill with the other end bent onto the sewing table Ill.

In the case of this conventional device, y types of members with different movements, such as cut fabric members (-), are required, and many actuators must be provided to drive each of these members separately, so the entire manufacturing device is becomes larger,
This has the disadvantage that it is not only complicated, but also tends to be expensive.

The present invention has an object to improve the above-mentioned conventional drawbacks.

The characteristic structure of the annular fabric manufacturing apparatus according to the present invention, which has been made to achieve the above object, includes a device that supplies a long strip of fabric to the sewing table, and a device that cuts the supplied fabric into a predetermined size from the end thereof. and a device that can freely clamp and release both ends of the dough that is cut or cut with this device, and that can cut both ends of the raw fabric by sequentially moving them in the direction of approaching each other in the clamped state. and a pair of arms for polymerizing the above-mentioned M-bonds.

The functions and effects of the above characteristic configuration are as follows.

In other words, by rotating the pair of arms that sandwich both ends of the fabric that has been cut or cut by the cutting device, both ends of the fabric can be superimposed on the sewing table almost simultaneously. Compared to the above, it is possible to reduce the number of movable structural members and actuators used for their skeleton as much as possible, and the entire manufacturing equipment can be made simple, compact, and cost-effective. reached.
