Licensee sought for technology enabling manufacture of self-supporting lower windings for sewing machines

The offered technology has been developed at the department of the Czech university, which has a long track of record in textile innovations. Self-supporting lower windings are windings especially designed for lock-stitch sewing machine. At present there are neither commercially available any technologies for the manufacture of self-supporting lower windings. There is also a demand from the textile industry for utilizing self-supporting lower windings on older textile machines. In comparison with direct competition, the offered technology of self-supporting lower windings differs by the absence of a supporting flanged tube. For utilizing self-supporting lower windings in sewing machines a new type of looper is available on the market, where the lower windings does not rotate and the thread is unwound from the centre of the package. This eliminates the inertial dynamic effects of the windings during stops and run-ups in the sewing process. This technology has been tested on a newly developed machine, enabling to manufacture up to 10 lower windings simultaneously. The achieved characteristics of the manufactured lower windings considerably increase the quality and productivity of the sewing process. Researchers are looking for partners interested in licensing the invention under a license agreement and start production of the offered technology.
