Document Type and Number:
WIPO Patent Application WO2000068478
Kind Code:
A9
Abstract:
The present invention provides an accumulator (36) for feeding yarn in an air jet loom, comprising: a yarn accumulating surface, wherein at least a portion (54) of the surface is inclined inwardly toward an axial centerline of the accumulating surface (56) and has a surface finish that reduces sliding friction between the surface portion and yarn contacting the surface portion; a winder (50) to wind yarn around the accumulating surface; and a device (66) to permit periodic removal of yarn wound around the accumulator surface (56, 60). In one nonlimiting embodiment of the invention, the yarn accumulating surface (56) of the accumulator comprises a plurality of spaced apart fingers (42) positioned and configured to provide discrete yarn contacting surfaces that form the yarn accumulating surface, and the surface finish comprises a textured finish that provides less surface contact between the yarn and surface portion.
