An apparatus for forming a sheet of material about a pot and applying a band therearound. The apparatus includes a table assembly, a pedestal, a plurality of spreader fingers, a plurality of release wedges and a plurality of linkage assemblies. The table assembly is provided with an opening and the pedestal is mounted for reciprocating movement through the opening. The sheet of material is formed into a cover about the pot by placing the sheet of material and pot on the pedestal and urging the pot through the opening. The spreader fingers are radially movable between a retracted position within the opening and an expanded position wherein the spreader fingers are positioned outside the perimeter of the opening. Each of the release wedges is located on the table assembly at the perimeter of the opening along the line of movement of a corresponding one of the spreader fingers. The linkage assemblies and the shape of the pedestal cooperate to move the spreader fingers in response to movement of the pedestal. With the fingers in the retracted position, a band is placed around the fingers. As the pedestal and pot are urged through the opening, the spreader fingers spread the band such that the band circumscribes the pot and cover. The release wedges then force the band off of the spreader fingers and onto the pot.
