Abstract: An improved punch and die assembly for use with a closure liner insertion device is disclosed. As contrasted with prior art construction, the assembly is supported upon a pair of vertically oriented posts located adjacent the periphery of a rotating dial, the vertical axis of each post lying in a vertical plane passing through the vertical axis of the punch and corresponding die. This construction permits installation of a standard punch and die unit in conjunction with closure liner insertion machines of varying dimensions, without substantial alteration.

Abstract: A rotary slitter for container closures of varying sizes is disclosed. The embodiments include swivel housings to permit rapid changing of internal tools, and a rectilinear knife blade which eliminates adjustment problems normally occurring with curved knife blades.

Abstract: A continuous motion sealer of a type typically employed for applying metallic foil seals to the mouths of containers for fluid comestibles is disclosed. The device includes means for cutting a flat seal of predetermined profile from a roll-supplied heat activated material, and transport the seal to the containers or other parts following which it is heat sealed. Improved camming means is provided which enables the sealing heater to engage a seal in the absence of other than vertical motion. A punch and die assembly includes a programmable electronic material advance mechanism. Each sealing head assembly includes an electronic band heater and thermocouple, as well as a vacuum pickup for individual seals. The thermocouple communicates with a separate sealing head temperature controller, programmable with regard to temperature setting, and an alarm connected to a system shutdown in the event of failure.
