This machine is designed to apply foil or plastic membranes to composite/plastic canisters, tubs and containers. Containers are timed into captivator-blocks by mean of a timing-screw. The blocks and screw index the containers to a sealing station where the container is grasped and supported by a heavy duty clamping mechanism. A rotary die-cutter completely cuts the membrane patch from the web and the patch is transferred independently by a vacuum transfer system and attached to the conduction sealing heads by vacuum. This method of cutting and transferring the membrane patch ensures a very accurate membrane placement and reduces film waste to an absolute minimum. Heavy-duty air cylinders apply the pressure necessary for a hermetic seal.
