Description

Предложение относитс  к известным уже устройствам дл  обрезки кромок шва с применением ножа, работающего от главного вала машины. Насто щее изобретение ставит своей целью упрощение конструкции путем непосредственного сцеплени  .кулачкового механизма ,-€ ножедержателем.The proposal relates to devices already known for trimming the edges of a seam using a knife operated from the main shaft of the machine. The present invention aims to simplify the design by directly coupling the cam mechanism, the knob holder.

На прилагаемом чертеже изображен -общий вид приспособлени .The attached drawing shows a general view of the fixture.

Приспособление состоит из изогнутого по форме головки машины рычага 4, несущего на одном конце нож 8, а другим поворотно укрепленного на двух конусных винтах на доске машины, и из кулачной муфты /, монтированной на главном валу машины. Дл  приведени  ножа в действие на рычаге 4 укреплено включающее и выключающее приспо :обление , которое состоит из детали 6, несущей стержень 3, на котором насажен ролик 2 сцепл ющийс  через прорез в рукаве машины с муфтой /, и из стопорного винта 5.The device consists of a lever 4 bent in shape of the machine head, carrying knife 8 at one end, and the other pivotally fastened with two conical screws on the machine board, and from a fist coupling / mounted on the main shaft of the machine. To actuate the knife on the lever 4, a switching device is turned on and off, which consists of part 6, a carrier rod 3 on which roller 2 engages through the slot in the sleeve of the machine with the coupling and the locking screw 5.

Дл  выключени  ножа достаточно освободить стопорный винт 5, и тогда стержень 3 опуститс , освободив ролик 2 от соприкосновени  с муфтой 7.To turn off the knife, it is enough to release the locking screw 5, and then the rod 3 will lower, releasing the roller 2 from contact with the sleeve 7.

Предмет изобретени .The subject matter of the invention.
