Title: Innovations of Josef Raschle in Yarn Texturing Technology
Introduction
Josef Raschle is a notable inventor based in Butschwil, Switzerland. He has made significant contributions to the field of yarn texturing technology, holding a total of 8 patents. His innovative designs focus on improving the efficiency and effectiveness of yarn processing.
Latest Patents
Raschle's latest patents include devices for texturing yarns by imparting false twist through friction. This friction false twist device features three parallel shafts arranged in an equilateral triangle, each carrying rotationally symmetric friction elements. The design allows for at least one shaft to be shifted relative to the others, facilitating easy threading. Additionally, the device incorporates a fourth shaft that, when connected by a line, aligns the centers of all four shafts in a kite-shaped quadrilateral. This configuration minimizes modifications to the belt length during operation, enabling the use of belts with minimal elasticity.
Another of his recent patents involves devices for determining the helix angle of twisted threads during false-twist texturing. These devices utilize a two-armed lever pivoted between its arms, with the thread passing over a convex spherical surface. Magnetic means bias the lever to a zero position, allowing for precise measurement of the helix angle. The design includes variations that enhance sensitivity and maintain twist density during processing.
