Is fitted into the fitting hole 31, the locking concave portion 44 of each connecting protrusion 43 is arranged to face the locking protrusion 38 on the piston 37 of each air cylinder 33. In this state, when the air supply from the air supply hole 41 is stopped and the air is discharged, and the air is supplied to the hollow portion 34 through another air supply hole 40, the piston 37 projects. Then, the locking projection 38 is engaged with the locking recess 44. The position of the locking projection 38 at this time is defined as the engagement position. The engagement of the two 38 and 44 reliably prevents the connection projection 43 from being detached. In this embodiment, a spring 39 is provided between the piston 37 and the inner wall of the hollow portion 34 so that the engagement projection 38 is held in the engagement recess 44 by the spring force. Therefore, even if an accident such as a stoppage of air supply into the hollow portion 34 or a pressure fluctuation occurs, the engagement relationship between the engagement protrusion 38 and the locking concave portion 44 is not released. Thereafter, the cloth W and the pocket pieces P are set on the folding machine as described above, and the pocket machine can be automatically sewn by operating the folding machine and the sewing machine. On the other hand, in order to perform a fold forming operation and a sewing operation of the pocket piece P having a shape different from that of the previously sewn pocket piece P, the gauge plate 14, the holding plate 19, the bent piece holding plate 24, and the feeder When replacing the plate 9 with another one,
While stopping the air supply to the hollow portion 34 through the air supply hole 40 and discharging the air in the hollow portion 34,
Air is supplied into the hollow portion 34 through the air supply hole 41. Then, the piston 37 is returned from the engaged position to the solid line position in FIG. 2 (the disengaged position), and the locking projection 38 is disengaged from the locking recess 44 of the connecting projection 43. Therefore, in this state, if the connecting projection 43 is separated from the fitting hole 31, the respective plates 14, 19, 24, 9 can be easily removed from the corresponding support. Further, as described above, in this embodiment, the gauge plate 14, the holding plate 19, and the bent piece holding plate 24 are separated from the holding position on the holding plate mounting surface 4a by the holding plate mounting surface 4a.
a is moved up and down between the
And the fitting hole 31 is firmly connected, so that no play occurs during the operation. The present invention is not limited to the above embodiment. For example, the connecting projection 43 is provided on the support side, and the fitting hole 31 and the connecting air cylinder 33 are provided on each holding plate side. It is also possible to arbitrarily change the configuration of each part without departing from the spirit of the present invention, such as by configuring or embodying a work holder used for sewing a predetermined graphic pattern or sewing an emblem. As described above in detail, according to the present invention, the holding plate can be easily attached and detached, and the holding plate can be firmly fixed to the support.
Therefore, highly accurate processing can be performed on the work cloth.
