A device for cutting of one or more sewing threads in a sewing machine, which operates with one under thread (15) and at least one upper thread (17), including a thread fetcher (18) which is displaceable to catch and bring with at least one of the threads to a cutting position, and a knife (26), which cooperates with the thread fetcher (18) to cut the thread or the threads. The thread fetcher is movable between the cutting position and at least one thread catching position to selectively catch the upper and/or the under thread. The device cooperates with the knot forming mechanism of the sewing device, whose gripper (12) brings the upper thread (17) in catching position.The device also enables the pulling down of the free end of the upper thread under the fabric before the sewing starts. |
