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.
