Garn posisjoneringsapparat

摘要

A yarn positioning apparatus for use in an automated seaming machine for forming a woven join between opposite ends of a length of woven fabric, of the type in which an auxiliary strip of threads are supported in parallel relation to the cross machine direction threads in the woven fabric. The opposite ends of the fabric are supported on opposite sides of the auxiliary threads and each end of the woven fabric includes a fringe of machine direction (MD) threads. The MD threads are successively separated from the fringe and interwoven with the auxiliary thread to form the join. The yarn positioning apparatus is comprised of a yarn gripper for gripping a previously woven yarn from a fabric fringe in a first orientation and repositioning it to a second orientation. The yarn is retained in its second orientation as it is translated for further processing.
