Abstract
A machine which forms openings in can ends and seals the openings with manually removable lengths of tape. The machine comprises a wheel and a plurality of plates having through passageways across which the can ends are supported. The plates are slidably mounted around the periphery of the wheel and are slid relative to the wheel between a first position at which punches carried by the wheel punch openings in the can ends when the wheel moves the plates along a first portion of the path, and a second position at which taping means mounted on a frame of the machine applies lengths of tape over the openings as the wheel moves the plates along a second portion of the path.
