Title: The Innovations of Stefan Krawietz
Introduction
Stefan Krawietz is a notable inventor based in Ebersbach/Fils, Germany. He has made significant contributions to the field of textile machinery, holding a total of 7 patents. His work focuses on improving the efficiency and functionality of drafting devices used in spinning machines.
Latest Patents
One of his latest patents is a drawing frame with aprons entwined around twin output top delivery rollers. This invention relates to a drafting device that features twin top front rollers surrounded by aprons. The aprons are guided around deflection members arranged above the area facing away from the clamping surface of the front roller pair. This design aims to achieve low-friction, brake-free, and low-wear running of the aprons by guiding them with only slight tension around the deflection members. The tendency of the aprons to assume a circular form in the circumferential direction is utilized to minimize contact pressure and tractive tension.
Another significant patent is a drafting frame for a spinning machine that includes a roving compactor. This drafting frame is equipped with at least one compaction unit where a perforated belt under suction draws together the fibers of a drafted roving. The belt is positioned next to a stripper that is spaced from the belt to remove fiber accommodations. The gap between the stripper edge and the belt is adjustable, allowing for enhanced functionality.
