Latest Patents

One of his latest patents is a receiving element for a yarn drawing nozzle of an open-end rotor spinning device. This invention relates to a receiving element designed to receive an interchangeable yarn drawing nozzle that can be magnetically locked. The receiving element is configured as an adapter that can be screwed into a central threaded bore of a thread channel plate in an open-ended rotor spinning device. This device is designed to receive a conventional yarn drawing nozzle equipped with an external thread. The adapter includes centering bores for receiving ferromagnetic centering lugs of a yarn drawing nozzle, along with a continuous bore whose internal diameter is adapted to the external diameter of the shaft of the yarn drawing nozzle. Additionally, the adapter is equipped with permanent magnetic pins that correspond with the ferromagnetic centering lugs of the yarn drawing nozzle.

Another significant patent by Schröder is related to a spinning device. This spinning device comprises a spinning box housing, a spinning rotor with a spinning cup on a rotor shaft, a cover element, and a traveling belt acting tangentially on the rotor shaft. It also features a rotor brake and a pivotable expander roller that can move within a maximum pivot angle via a pressure lever system connected to the brake gear of the rotor brake. This system ensures that the expander roller is automatically lifted off the tangential belt when the spinning box is opened, applying the rotor brake to the rotor shaft.
