る。2. Description of the Related Art In general, a waist belt (hereinafter referred to as a belt) 2 of jeans is attached to a body 3 as shown in FIGS.
Sewn as shown. First, the belt-shaped cloth constituting the belt 2 is folded in half, and the entire periphery of the waist of the body 3 is inserted between the two-fold while the lower edge is wound inward. Next, the upper portion of the belt 2 and the overlapping portion of the belt 2 and the body 3 are sewn with sewing threads 4 and 5, respectively. In this state, both ends of the belt 2 at the front portion of the jeans 1 are left as unsewn portions 2a as shown in FIG. 7A, and the folded portion 2b extends from the end of the body 3 to which the fastener 6 is attached.
Is projected in an unsewn state, and is sent to the next process in this state.

さだけ飛び出した位置２ｄで切断する。Therefore, conventionally, the belt 2 is continuously supplied from the belt supply device to the sewing position of the sewing machine. After the belt 2 and the body 3 are set at that position, the belt 2 is moved from the waist of the body 3 to a predetermined length. And cut at the position 2c where the protrusion 2c protrudes.
Then, the upper portion of the belt 2 and the overlapping portion of the belt 2 and the body 3 are sewn with sewing threads 4 and 5, respectively. Also,
After the sewing is completed, the belt 2 is similarly cut at a position 2d where the rear end protrudes from the body 3 by a predetermined length.

Is provided with a notch 14c for guiding the upper side of the belt 2 and the folded portion, whereby the belt 2 is reliably pressed without shifting, so that the cut portion is securely parallel to the waist line of the body, And it is cut with high dimensional accuracy. Next, the operation of the presser device thus configured will be described.
When the joint 2e of the belt 2 is detected by a sensor (not shown) disposed in the feed direction of the advance roller 12b, the knee switch (not shown) is operated to operate the cloth presser foot 11.
Then, the advance roller 12b is moved upward (the position where the advance roller is moved is referred to as a retracted position), and the stopper 15 is lowered, the body 3 and the belt 2 are set, and the body 3 is brought into contact with the stopper 15. (See FIG. 4).
At this time, the gripping mechanism 20 is moving to the sewing machine side, and a part of the leading end of the belt 2 is on the lower clamp claw 22.
