Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) There is a clothing press machine in which a waist interlining belt and a collar interlining are heat-bonded to a surface fabric.

The present invention relates to a pressing method suitable for adhering a composite adhesive interlining in which a stretchable body such as a rubber belt is connected in the middle of the interlining in this type of pressing machine, and an apparatus therefor.

(Prior Art) General clothing press machines are classified into the international patent classification D06F71 / 00, for example, Japanese Utility Model Publication No. 60-12549 and Japanese Utility Model Publication No.
Items related to 0-12550 can be found. There, the dough is sandwiched between a pair of press bodies equipped with heating means, and press processing is performed under heating and pressure. An application of such a press machine to adhesively fix an adhesive interlining is an interlining adhesion press, which is used, for example, to heat and bond an interlining belt for a waist to a surface material.

By the way, an elastic body such as a rubber belt or a belt made of elastic cloth may be connected in the middle of the interlining belt in order to allow the waist size to have a certain margin or to make the waist size free. Regarding the bonding of such a composite interlining material to the surface material, conventionally, either the manual operation using an electric heating iron is used or the interlining material is adhered by an interlining press machine after a preliminary step by manual work. It was according to the method.

When manually adhering, as shown in FIG. 10, mark the front cloth 1 in advance, position the composite adhesive interlining 2 according to the mark, and then use the electric iron F to adhere the adhesive core.

(Processing procedure) In FIG. 6, the initial adjacent distance M between the left and right press bodies 4A and 4C and the lower press body 4B fixed to the center is set. The expansion margin of the elastic body 2B, that is, the interval corresponding to the length of the gathered C portion (see FIG. 5) of the outer cloth 1 attracted by the elastic body 2B at the time of expansion is the initial adjacent interval M, and the adjustment handle 16 is The interval is set by operating and moving the left and right lower press bodies 4A and 4C. At this time, the output rod 24 of the air cylinder 23 is set in the most retracted state.

By fixing the position of the stopper 29 and fixing it, and defining the protrusion stroke of the output rod 24, the left and right lower press bodies 4A
4C and the lower press body 4B in the center are set to the adjacent distance N during processing. This set interval N corresponds to the effective width of the elastic body 2B in the free state. The left and right widths of the lower press body 4B in the center are appropriately changed so that they are the same as the left and right widths of the adhesive interlining 2A corresponding to the central front body of the composite adhesive interlining 2.

After preparing the processing as described above, as shown in FIG. 7, the front cloth 1 is placed on the press surfaces of the lower press bodies 4A, 4B, and 4C for alignment, and fixed by the holding means 35.

Next, the air cylinder 23 is operated to cause the output rod 24 to project, and the left and right lower press bodies 4A and 4C are moved to the central lower press body 4B.
To move to the adjacent space N during processing. As a result, as shown in FIG. 8, the outer cloth 1 is sewn at a position corresponding to the elastic body 2B between the facing surfaces of the left and right lower press bodies 4A and 4C and the central lower press body 4B. Escape in the state, only the fabric part corresponding to the adhesive interlining 2A is the lower press body

To heat. After a certain period of time, the upper and lower press bodies (3 and 4A, 4B, 4CB) are returned to their original positions before being pinched. In this state, the vacuum pressure of the holding means 35 is released, and the surface material 1 to which the composite adhesive interlining 2 is adhesively fixed is removed. The air cylinder 23 is operated to return the left and right lower press bodies 4A and 4C to their original positions to prepare for the next bonding.

After that, the outer cloth 1B and the elastic body 2B are sewn together with the elastic body 2B stretched and deformed to obtain the skirt S having the rubber gathers C on the left and right sides of the waist as shown in FIG.

When forming a rubber gather at one central part of the back (or front) body, remove the lower press body 4B in the center and set the initial adjacent spacing M with the left and right lower press bodies 4A and 4C. Depending on the case, one of the left and right lower press bodies 4A and 4C is brought into contact with the central lower press body 4B, and only the other lower press body is driven to contact and separate to bond the composite adhesive interlining 2. You can also do it.

(Another embodiment example) The drive source for driving the upper and lower press bodies (3 and 4A, 4B, 4C) does not necessarily have to be an air cylinder.

(Effects of the Invention) As described above, according to the method of the present invention, the non-adhesive portion of the table cloth 1 is slackened and allowed to escape, and the composite adhesive interlining 2 in the free state is simply determined as a unit and overlaid. Since the adhesive interlining 2A can be adhered to the outer fabric 1 at once, a series of operations from positioning of the outer fabric 1 and the composite adhesive interlining 2 to adhesive fixing can be performed without any skill difference, and the quality is constant and good. The finished state can be reliably obtained in a short time.

Further, according to the bonding apparatus of the present invention, a series of operations relating to the bonding of the interlining material can be automatically performed, so that the processing time and the number of processing personnel are reduced as compared with the case of the conventional manual bonding work. Therefore, the manufacturing cost can be reduced accordingly. In particular, when the interlining bonding step is interposed in the sewing line, the processing time is short, and thus there is an advantage that the consistency with other sewing steps can be easily achieved.
