Supporting wedge (1) for preventing rolls of lacerable laminated plastic sheet from rolling on a substantially plane surface and comprising a primary supporting face, which is adapted to engage the cylindrical member and is formed as a section of a circle periphery when seen in a sectional view. The wedge is made in one piece of an expanded polystyrene foam, and the bottom side (3) of said wedge (1) facing the surface is provided with a friction-increasing coating (5) of hot-melt glue sprayed thereon in stripes extending in the longitudinal direction of the wedge (1). As a result, rolls of lacerable laminated plastic sheet are supported in such a manner that the many outer layers of laminated plastic sheet are not damaged because the wedge (1) yields slightly when subjected to the pressures of the roll. |
