Title: Bodo Wehmeyer and His Sewing-Machine Innovations.

Introduction

Bodo Wehmeyer is an inventor associated with Bielefeld, Germany, and with sewing-machine technology developed at Dürkoppwerke GmbH. His work addresses practical challenges in handling tubular fabric and cutting thread chains during sewing operations. He is credited with 2 patents.

Latest Patents

One of Wehmeyer’s patents describes a sewing machine with a tensioning device designed to align tubular workpieces made from medium-heavy to heavy sewing material. The device uses tensioning rollers fitted with alignment members distributed around their circumference. After a sensor scans the workpiece’s opening edge, pressure fluid moves selected members radially and axially so their gripping surfaces can shift the fabric transversely to its direction of rotation.

Another patent concerns a sewing-machine cutting device that severs the thread chain between successive sewn parts. A hook lifts the chain through an opening in a holder, and scissors cut the raised thread. The holder stabilizes the upstream sewn part while allowing the downstream part to move slightly, enabling a single cut near both parts. A sensor detects the trailing edge of a sewn part and triggers a stitch counter, which allows the machine to complete a predetermined number of stitches before stopping for the cut.

Career Highlights

Wehmeyer’s patented work focuses on improving the precision and reliability of automated sewing processes. His inventions address fabric alignment under tension and coordinated thread-chain cutting between sewn parts.

Collaborations

Wehmeyer is associated with Dürkoppwerke GmbH. His listed coworkers include Kurt Biermann and Gerhard Steppat.

Conclusion

Bodo Wehmeyer’s patents reflect a practical contribution to sewing-machine engineering, particularly in workpiece alignment and automated thread-chain cutting.
