New insertion rules for a new insertion system

The new insertion device FillMax was developed by Picanol NV, Ieper/Belgium, in cooperation with the Department of Textiles of Ghent University, Ghent/Belgium, in the NIRIS project (IWT project 080642). The FillMax system consists of buffering into a sieve and inserting from a sieve. Careful timing of buffering and insertion by new insertion rules for a new insertion system (NIRIS) enables the use of all parts of the conventional weft insertion system. FillMax allows weaving mills to increase production speed by 10% without a corresponding increase in yarn tension, or allovvs weaving at the same speed with a significantly lowered air pressure at the main nozzles. Speed and peak tension reduction is based upon a frictionless mechanism and applicable to even delicate yarns. Fabric quality remains unaffected.
