In weaving from creel, the warp threads are fed to the weaving machine via feeding units that are under consistent tension.
The feeding units are integrated in existing and new racks.
The number of feeding units is dependent on the fabric construction.
Each feeding position is separately powered by a gear motor.
In ribbon weaving mills the warp yarns are often stored on several sectional warp beams. For conventional negative electronic let-off devices, the warp thread tension is created by braking the bobbins with belts or cables. These devices are cost-effective and very simple, but a consistent thread tension from a full to empty bobbin is not ensured. They do not provide an optimal solution for high-quality and elastic fabrics.
There are various warp thread feed systems available for improving these negative characteristics.
