The Zero Twist Feeder is an active controlled system to feed flat tapes and yarns without twist to a weaving loom
The two companies IRO AB and Vintecc bv have jointly developed the Zero Twist Feeder. This is an actively controlled system for the twist-free feeding of flat slivers and yarns to a weaving machine. Weaving machines operate at high speeds and pull on the bobbin at very irregular intervals. A buffer arm was used to compensate between the bobbin and the rapier. The buffer arm delivers exactly the required amount of yarn to the weaving machines at the optimum speed for weft insertion. During production, speeds of up to 850 meters/minute per insertion can be achieved. The AX8000 servo drives and superior EtherCAT communication are the perfect combination for meeting the fast cycle times we require.
