Abstract

The invention provides tubular core assemblies for winding or unwinding of sheet material, such as newsprint, wherein the opposed ends of an elongate cylindrical core are provided with core insert members securely attached by adhesive bonding to the inside and surfaces of the cylindrical core for reducing the inside diameter of the ends of the cylindrical core. The annular core insert members each include a substantially frustoconical exterior surface for joining to the inside periphery of the ends of the cylindrical core and the opposed ends of the cylindrical core have substantially frustoconical interior surfaces which match the substantially frustoconical exterior surfaces of the annular core insert members. The annular core insert members can readily be bonded to the ends of the main core body by axial insertion into the core because surface-to-surface contact of the bonding surfaces is improved and because adhesive bonding material is not scraped off during the insertion process. In addition, the core insert members have improved axial load capabilities.
