2072576 9208830 PCTABS00013 The insertion machine comprises an insertion frame with a tensioned layer of warp threads, a device with separators for dividing the individual warp threads of the layer and a device for presenting the divided warp threads to an insertion member. The latter has an adjustable-travel transport claw (31) for the controlled transport of the separated thread ends to a position where they can be taken over by the insertion member, first means (32) to monitor the thread during the transport process and second means (21) to monitor the thread during insertion. This ensures full control of the thread and largely eliminates breakdowns.
