Abstract

After button-seaming step is completed, and/or a knot-yarn-winding step is completed, a moveable cutting blade swings from the lateral side position of the pin plate toward the lower position of the pin plate, it can go across the button-seaming thread and/or the location between knot-yarn-winding thread and looper. In the portion of two pin threads laterally hung in an approximately triangular coil shape, only the pin thread portion connected to the button-seaming thread and/or the lateral side of the end part of the knot-yarn-winding thread oppositely pulls up the guide, so as to cut the pin thread portion of the guide by the sliding-connection function of the moveable cutting blade and the fixing cutting blade formed in the pin plate. As a result, the damage of blades and decrease of sharpness can be inhibited, so that the replacing period is extended to reduce the troublesome procedures and the operation costs. Also, only the preset pin thread portion is substantially cut with the length and shape of the residual thread in good condition.
