Abstract
A structure is provided for supporting and spacing rolls of web material. The structure includes an elongated member with first and second opposed surfaces. The first surface has a plurality of spaced, semi-cylindrical indentations therein for receiving the rolls of webbed material. A recess is located in each side portion of each semi-cylindrical indentation so as to form corresponding convex protrusions on the second, opposed surfaces. Bridging is placed along the second surface between the convex protrusion formed by a recess and a first semi-cylindrical indentation and the convex protrusion formed by the recess in a second, adjacent semi-cylindrical indentation.
