TRIPLANAR BLADE EDGE FOR YARN TEXTURIZING

摘要

The invention is directed to a yarn-texturizing blade having an edge consisting of three intersecting planes. The three intersecting plane edge facilitates fabrication of the blade from very hard materials because of the ease in grinding the planar surfaces and permits ready evaluation of the performance of the blade on the yarn. The blade has the further advantage in that, because of its configuration, it is resistant to chipping and offers processing advantage to the fiber which is passed over the two consecutive edges formed by the three intersecting planes resulting in a better product and allowing a much higher speed for the passage of the yarn over the blade. This triplanar edge also allows use of edges with much smaller radius of curvature without cutting the fiber.
