TAKE-UP TUBE OF WOUND YARN PACKAGE AND DEVICE FOR MANAGING WOUND YARN PACKAGE

摘要

In an arrangement for sticking a bar code to a paper tube or printing the date directly on the paper tube, the bar code may be stripped or the print may become blurred when a package is delivered. On the other hand, when a means for storing identification information such as a bar code is provided in a tray independent of the package, management of package is complicated. A bobbin (10) becoming the core tube of a wound yarn package (8) is a paper tube formed by winding paper into a tubular laminate of paper where a thin leaflike (label) storage medium (13) is buried between an intermediate layer (10b) and an outer layer (10c).
