ABSTRACT OF THE DISCLOSURE The disclosure relates to a core for holding web material. The core includes a first cylinder having an axis of rotation and an axially extending slot for receiving the web material, a second cylinder within the first cylinder and substantially concentric with the first cylinder about the axis to form an annular channel therebetween and an annular channel floor between the first and second cylinders to main- tain the cylinders in fixed substantially concentric relation. The core also includes a post within the annular channel and angularly spaced from the axial slot beyond the point of tangency between the outer peripheral surface of the second cylinder and the axial slot. With an end of the web doubled over and threaded through the slot into the channel and looped around the post, the conjoint effect of the restraining action of the post on the web and the frictional contact between the resulting two layers of the web about the second cylinder holds the web securely to the core.
