Abstract

단추구멍 재봉틀은 실 절단 및 조임 장치(27)를 구비하며, 이 장치(27)의 한편으로는 재봉품 와이어 프레임(1)의 진행방향(V)으로 횡단하여 연장되는 측면의 운동과 다른 한편으로는 이 장치(27)의 개방 동작이 캠기구(18)에 의해서 제어된다. 캠기구(18)는 각각의 이들 두 기능을 위해서 고유의 캠(13, 15)을 포함한다. 종운동을 위한 캠(13)은 개방동작을 위한 캠(15)에 대해서 부분적으로 조정 가능하고, 이에 의해 꿰메애 할 실단부의 제1단추구멍 술장식의 구성의 경우엥서의 위치가 얻어진다.The buttonhole sewing machine is provided with a thread cutting and tightening device 27, on the one hand of which the movement of the lateral side extending transversely in the direction of travel V of the sewing wire frame 1 The opening operation of the device 27 is controlled by the cam mechanism 18. Cam mechanism 18 includes unique cams 13 and 15 for each of these two functions. The cam 13 for the longitudinal motion is partially adjustable with respect to the cam 15 for the opening operation, whereby the position of the servo is obtained in the case of the configuration of the first buttonhole swag of the thread end to be sewn.
