Abstract
Thread-crimping machines with enhanced throughput are detailed. One or more drive rolls forming parts of the machines may be grooved to group centrally the entering threads without materially adversely impacting driving and crimping operations of the machines. Thread-focusing components also may be employed upstream of the inlet areas.
