Abstract (en)
[origin: EP2508665A2] The method involves moving a lower thread between a thread outlet opening at a bobbin case and a stitching hole by control edges (17a, 17b). The lower thread is guided into a thread storage of thread catchers (19a-19c). An upper thread is gripped by a hook point, and a needle thread and a material thread are splayed. The lower thread guided into the storage and the upper thread gripped by the hook point are pulled out, and the thread catcher is moved to an initial position, and a detachable end of the upper thread is pulled out from a thread cutting unit by a thread lever. Independent claims are also included for the following: (1) a method for sewing or stitching of upper and lower threads (2) a device for executing a method for cutting upper and lower threads.
