Needle wheel weft straightener - Import export

Removing irregular distortions Asymmetrical distortions (wavy, S-shaped, etc.) in textiles have always represented a huge challenge in the textile industry. A special straightening approach is needed particularly when the straightening process does not take place in combination with a stenter (e.g. before decatizers, digital printing systems, etc.). To restore the warp and weft threads to their original state, the Orthofact RMB generates a defined lateral tension using freewheeling, inclined pin wheels. This cross-tension stretches the warp threads. The resultant force controls the freewheeling pin wheels, since the weft threads will always seek out the shortest path from selvedge to selvedge. Distortion, no matter whether wavy or S-shaped, will be corrected.

Removing all types of distortions The fusion of pin wheel and roller straightening technology perfectly combines the advantages of both technologies and provides amazing straightening results. It provides reliable, quick distortion correction also for asymmetric web distortion. An infinitely variable unclipping roller minimises residual bow and edge distortions. The intelligent drive station with special voltage control for smallest product distortion activates or deactivates automatically (e.g. in case of blockages). A bypass function is available at the push of a button for products that cannot be straightened with the pin wheel.
