Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 149 words
Apparatus to heat shrink a film of heat shrinkable film around a roll of coins comprising: a conveyor, said conveyor having a guide platform with a convex upper surface, said conveyor including a plurality of freely supported rollers in contact with said convex surface, means supporting adjacent rollers from one another a distance substantially greater than the diameter of said rolls of coins to provide a space between adjacent rollers a shrink oven operably associated with said conveyor, means to supply film wrapped coin rolls into the spaces between adjacent rollers and means to interconnect said rollers into an endless belt and means to drive said endless belt of rollers to transport coins from the supply means to said shrink oven and cause said rollers to be rotated by said convex surface to rotate rolls of coins in said space between adjacent rollers to evenly shrink the film therearound.
