ABSTRACT:
A low-cost flexible, initially flat, relatively thin, nonmetallic core for supporting a web of material wound therearound and which is adapted to be positioned about a cylindrical winding mandrel in a smooth, closely fitting, circumscribing fashion without an attentant core slippage problem as has occurred with past devices for this purpose. A tongue forming a part of the core blank is provided for insertion within an axial slot in the winding mandrel, thereby positively preventing relative movement between the core member and the mandrel. In a preferred form, the core is fabricated from paper stock or yieldable synthetic resinous materials with the tongue thereon which is bendable for insertion in the mandrel slot being either removable or shiftable to recessed position after use thereof for maintaining a smooth, continuous, uninterrupted inner surface on the web core. By virtue of the thin, flat, nonmetallic nature of the core, fabrication, shipping and storage costs are drastically reduced and installation thereof is quickly and easily accomplished without resort to complicated apparatus for insuring a secure, nonslip fit on the winding mandrel. Means are also provided for facilitating proper positioning of the cores on the winding mandrel.
