Abstract: Apparatus and process for cold drawing a disk into a cap for a paper core. The process comprises cold drawing a disk to form a cylindrical cup having a rim and a socket, removing the central portion of the cup leaving a flange, straightening the flange and trimming the rim. The resultant cap is characterized by having a uniform-sized rim of a width equal to the width of the socket.The apparatus comprises a press having a fixed portion and a movable portion, a cylindrical member mounted on the fixed portion, a ram and a number of opposed cylinders carried by the movable portion, and means for moving the movable portion toward the fixed portion.

Abstract: A tubular paper core, about which a hard surface floor covering is coiled, is provided at its opposite ends with a pair of cap assembages, each of which includes inner and outer clamping disks and a collar, each disk formed with a central opening. The side margins of a web, which is wrapped about the floor covering roll, are crimped and glued to the exterior face of the inner disk and the interior face of the outer disk. The collar, which includes a tubular neck portion and an annular flange portion, is disposed between the disks, the flange portion being captively held between the disks and the neck portion being received within the opening formed in the inner disk and the tubular paper core.
