Package tube for yarn winding - has reflecting layer surrounded by pressure relief tape to control yarn still stored on package

摘要

A package tube for the winding of a yarn incorporates a device for the production of a reflection signal when the winding only consists of few yarn layers. The device is equipped with a reflecting layer, which is located on the tube and surrounded by a pressure relief tape with openings in order to prevent the reflecting layer from being damaged by the tautly wound yarn. ADVANTAGE - The package tube has a reflecting layer that permits a large number of windings, can be installed later and is protected from damage.
