The Vacuum Seamer is suitable for the double seaming of containers to be vacuum-sealed. The Seamer is placed inside a stainless steel cylindrical chamber.
The machine is constantly and automatically supplied with both the full cans and lids through a process that avoids air filtering inside the chamber. The suction pump, that is outside the chamber, draws almost all the air (90% = 0.9 bar). An automatic system controls and keeps constant the chamber vacuum level. The cans used for this process can be made of cardboard, aluminum, plastic, tinplate, etc. with “Open Top”, “Easy Open” or “Easy Peel” lids. The stacked lids are divided one by one by a screw and are then fed until they reach a raising can that picks them up. During the seaming process the cans are put on specific rotating plates and raised until they reach the lid with which they will be seamed. Specific seaming rolls hermetically seal cans and lids. The seaming process consists of two phases. In the first phase metal sheets are prepared and bended, while in the second phase lids are hermetically sealed with containers.
