This machine is to seam the food cans. The body of the can and the cap of the can are sent through different entries and then assembled in the vacuum chamber inside the machine. This seamer uses the double fold seal system: the first seal presses the body and the cap together, and the second seal seams the can completely. This machine was made in 1973 and can seam 70 to 80 cans per minute. (Donated by Huizhong Food Co.)
