Abstract
In the thread-guide arm (11), the thread-guide members (15 to 17) arranged above the thread-guide pulley (12) are formed in a thread-guide star (20) which is arranged immediately in front of a thread-restraining plate (21) and is preferably made in one piece with the latter. The thread-restraining plate (21) has a smooth outer edge having no acute angles, and the exposed edges of the thread-guide star (20) are rounded or bevelled, so that no threads can catch on the thread-guide star and the thread-restraining plate.
