Abstract
To prevent the formation of remnant thread pieces due to response of a thread cutting apparatus 2, 3, 4 coupled to a thread or yarn cleaning device 36, which erroneously responds with an 'off-size' signal upon a thread break, the cutter blade is guided in front of the thread when tensioned--under ordinary conditions--but loose if the thread should be broken. Under tension, movement of the cutter blade 2, 3 will sever the thread; when the thread is slack, the cutter blade can move into a groove 4, 4' of a counter element or anvil, which groove is deeper than the travel of the cutter blade to accomodate the slack thread. For heavier threads, the forward portion of the cutter element can be movable (FIGS. 4-6) to be pulled against a counter surface 14 by a taut thread, but to engage into the deeper groove 4' by a slack thread not having the pulling action on the blade.
