Abstract
Apparatus and method for inserting a plastic cap into the open end of a roll. Spaced rolls are moved downstream along a continuously moving conveyor and are lifted from the conveyor for capping. A cap gravity falls down a chute to a loading position where it is picked up by a plunger and seated in the end of the lifted, aligned roll. The capped roll is then returned to the conveyor.
