Straightening - 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.

When the going gets rough ... The Orthopac CRVMC is especially designed for high mechanical load. Thanks to reinforced components, it is ideal for processing very heavyweight and wide materials. The arc of contact of the straightening rollers thereby depends on the desired straightening effect. With products without skews and bows, the straightening rollers are not enveloped unnecessarily. When the straightening rollers engage with the product, the uniform contact of the straightening rollers with the product is ensured over the entire width. This becomes possible through our innovative and unique roller positioning drive.

Heavy-duty weft straightening The heavy duty version. High demands due to large product widths (e.g. carpet) or dimensionally stable textiles with defined skew settings (e.g. denim) require a more solid configuration. The frame, bearings and rollers are designed for high loads. Available with up to 5400 mm working width.

Fine-tune straightening for heavyweight fabrics The special strength of the Orthopac GMFRC is the extremely high straightening accuracy at relatively small distortions. Thanks to reinforced components, it is ideal for processing really wide, heavyweight materials such as denim. The compact straightening unit is equipped with a skew and bow roller as standard. This arrangement allows for very fine adjustment of the straightening effect while permitting small device dimensions.

Fine-tune straightening of residual distortion This model represents a compact fine-straightening system for the correction of residual distortions. The special strength of the Orthopac MFRC is the extremely high straightening accuracy at relatively small distortions. The compact straightening unit is equipped with a skew and bow roller as standard. This arrangement allows for very fine adjustment of the straightening effect while permitting small device dimensions. Available with hydraulic or electrical straightening roller adjustment.

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.
