A can seal applier has an indexing mechanism carrying endless belt and pulley sets at four stations. The pulley sets include a pair of movable pulleys that close on opposite sides of the can and wrap the belt around the can to hold the can on the indexing mechanism and rotate the can at a seal wrapping station. A continuous length of seal is fed to a vacuum gripper wheel, and a knife cuts off a length of the seal that is wrapped around the can by the gripper wheel as the can rotates. At another station a gripper draws the free ends of the seal together for joining by a fuser, and at another station the movable pulleys are spread apart to release the can and move it off the indexing mechanism.
