ABSTRACT:
Apparatus for applying disc-shaped end walls to the end faces of rolls of convoluted paper in a positioning unit wherein the rolls are maintained in horizontal positions has a magazine with two rows of floor-mounted pallets for stacks of superimposed end walls having different diameters. A conveyor which is mounted for travel between the two rows of pallets has lifters which can simultaneously pick up end walls from selected pairs of transversely aligned stacks and delivers the thus lifted end walls to an orientation changing unit which moves the end walls from horizontal into vertical planes and centers the end walls prior to applying them to the respective end faces of the roll in the positioning unit.
