End caps are pressed into the opposite ends of cores of wound rolls of paper, such as toilet tissue, paper towels and the like, by transferring end caps in succession from a rotating drum feeder located at each side of the path of movement along which the rolls are moved to end cap holders mounted to move in an endless course at each side of the roll path wherein each holder picks up an end cap from its adjacent feeder and moves it in synchronism with movement of the rolls along the roll path. The endless course of the end cap holders at each side of the roll path has a portion thereof which travels along a line that approaches the center line of the roll path so that the end cap holders each press an end cap into an end of the roll core and release the cap to the roll. A positioning paddle having radial blades is mounted to rotate on an axis below and perpendicular to the center line of the roll path with the blades engaging rolls in succession and moving them along the roll path in synchronism with movement of the holders along the portion of endless course which approaches the roll path center line. |
