Title: Elastic bobbin body
Inventor: MASUDA TAKESHI
IPC: B65H55/04
Filed: 1991-10-29
Abstract: PURPOSE:To provide an elastic bobbin body where neither falling-off of yarn from the outermost layer generated during the handling operation and unwinding operation nor breakage of the yarn may be realized and the handling ability is excellent. CONSTITUTION:An elastic bobbin body consists of a yarn layer (B) where the winding width gradually increases from the outermost layer toward the inner layer, and a yarn layer (A) where the yarn is wound with a constant winding width and a constant winding angle.
