Loop formation of the thread is observed

The chains of small parts formed in this way, which, however, can be whole trouser legs or the like, have so far been cut apart by tape, which is laborious and costly, since in addition to the appropriate cutters are required or the sewing machines have come to a standstill in the meantime. A thread chopper has now become known, which is arranged behind the ifadel.
