The Zero Twist Feeder delivers a tape yarn or fibre tow to the weaving machine without any twist. It keeps the yarn constantly stretched to avoid the risk of any snarls or twisting of the tape.
The ZTF is designed for use with rapier machines. It can be installed on new CAN communication machines, or retrofit to older non-CAN communication machines using a specially designed conversion kit.
The ZTF is supplied as either a single channel unit, or as a weft mixing version.
How it works
The bobbin is rotated by a motor, allowing delivery of the yarn without twist at an average speed of the weaving machine.
A buffer arm, synchronised with the rapier movement, buffers the yarn being rolled off the bobbin at a continuous speed and delivers the exact amount to the weaving machine at the correct speed needed for the weft insertion.
A tension and sensor arm ensures that constant yarn tension is kept during the whole insertion cycle.
