Abstract: A can end lining mechanism has been devised for sequentially advancing can ends from a downstacker mechanism into registry with each of a series of can end receiving recesses in a rotary chuck table where as each can is advanced into a recess it is simultaneously lifted, rotated about its own axis, and rotated about the axis of the chuck table while sealant is applied to the peripheral groove of the can end for a predetermined time interval, after which the lined end is released and the centrifugal force of rotation of the table is sufficient to discharge the end. Feed interrupt mechanism is provided throughout in order to interrupt delivery of the ends from the feed area as well as to interrupt the application of sealant when a can lid is not properly in position. Synchronous drive means are provided for coordinating the movement of the can lids from the feed area through the discharge station.

Abstract: Can bodies are held by means, such as a vacuum, magnetic or other means onto rotating, disc-shaped pads which accompany the cans throughout an indexing route. A can centering guide positions each can on the center of one of the pads to insure eventual alignment with spray guns at two spray stations downstream. A spinner-drive belt encircles a turret and forms a substantially continuous rotational drive for spinning the can-bearing pads. When a vacuum means is employed, the vacuum means comprises a vacuum manifold in the rear of the turret and has manifold groove for vacuum communication with the can through the vacuum pad. As the can-bearing vacuum pads pass along the manifold groove, the cans, being securely centered on the vacuum pads, rotate at the same velocity as the belt-drive vacuum pads.

Abstract: The interior of a pipe is coated with a uniform thickness of plastic. A fluidized bed of heat-meltable plastic material in particular form is connected to the inlet end of the pipe, while the opposed end of the pipe is made attachable to a source of reduced pressure. A source of compressible fluid is also connected to the inlet end of the pipe. The pipe is preheated and then rotated axially while the compressible fluid flows therethrough. The compressible fluid flowing to the inlet is suddenly terminated while a flow from the fluidized bed is immediately established so that the vacuum at the outlet end of the pipe causes uninterrupted mass flow and pulls a finite pocket of the finely divided plastic into the pipe. The flow of particular plastic material is terminated, while the flow of compressed gas is immediately re-established, thereby pushing the pocket of plastic material into and through the pipe.
