It is an object of the present invention to provide a device for automatically transferring the semi-finished product from the semi-finished product manufacturing machine to the gusset stitching machine.

[Effect]

With the above configuration, when the semi-finished product is transferred by holding the central opening of the crotch that receives the work of the gusset stitching machine with the holding device, the legs and body of the semi-finished product are held in place during the removal, transfer and placement. Since each operation can be held so as not to be disturbed during each operation, complete automation can be achieved, which not only reduces actual human intervention as much as possible, but also allows the gusset sewing machine to This has the advantage that the placement of semi-finished products on the machine becomes uniform.

〔Example〕

BRIEF DESCRIPTION OF THE DRAWINGS The features of the invention will be explained in more detail below with reference to the accompanying drawings, which illustrate one embodiment of the invention.

As can be seen from the accompanying drawings, the method of the present invention involves manually separating the two legs of the pantaste tucking semi-finished product in order to facilitate the complete automation of the production of the pantaste tucking. This phase includes the following steps. That is, first of all, in order to be able to access the automatic device to the opening 2 provided for sewing the gusset, the legs 30, 31 of the semi-finished product 1 for pantaste sewing are sewn into two separate vertically aligned Pneumatic suction cylinder 3
At the same time, the body 35 of the semi-finished product 1 is fixed to the semi-finished product manufacturing machine 3 by the suction head device 34, and the remaining legs 3 of the semi-finished product 1 are sucked into the semi-finished product 1.
1 and 32 are separated from the semi-finished product manufacturing machine 3.

The semi-finished product 1 is then captured by a capture device or fork 19 through the opening 2 and the opening 2 is widened. The opening 2 initially has an oval shape, but takes on a circular shape in order to enable elastic capture of the semi-finished product. Such expansion is effected by radial expansion of the forks 19.

Next, when the suction of the suction cylinders 32 and 33 is stopped, the trunk 35 and both legs 30 and 31 are released.

Next, by rotating the semi-finished product 1 hanging down by the fork 19 through the opening 2 by 90 degrees downward, the semi-finished product 1 is transferred to the cylindrical support 4 of the gusset sewing machine.
Move it to a position where it aligns below.

The edge 37 of the semi-finished product with the fork 19 captured thereon is then raised to a position ready for gusseting around the tubular support 4 .

The edge 37 is then placed on the base of the cylindrical support 4.

Then, the fork 19 is lowered and retracted.

Furthermore, as is evident from the accompanying drawings, the machine for carrying out the above method forming part of the invention comprises:
