摘要： A looper is brought into an advance state at the end of sewing, and a looper thread hanging hook arranged on the right rear side of a needle drop position is forced to advance and retreat to catch a looper thread running to the rear side of the looper and hold it on the rear side of the needle drop position. After performing sewing for one stitch in this state, the thread cutting hook arranged on the right side of the needle drop position is forced to advance and retreat to catch the looper thread running to the rear side of the looper with a first hold section and catch needle threads and the looper thread held by the looper thread hanging hook with a second hook section, and then these threads are collectively cut by bringing them into slide-contact with a thread cutting knife.
摘要翻译：在缝合结束时将弯针器置于提前状态，并且设置在针落位置的右后侧的弯针螺纹钩钩被迫前进和后退以捕捉运行到弯针后侧的弯针线并将其保持在针落位置的后侧。在该状态下进行一针缝合后，设置在针落位置右侧的线切割钩被迫前进和后退以用第一保持部分捕捉到弯针后侧的弯针线，并且抓住针线和由弯针线钩挂钩的弯针线与第二钩部分接合，然后通过使其与切线刀滑动接触而将这些线共同切割。
