Abstract
An automatic sandwich preparation system in which each sandwich is prepared under the control of a computer with condiments as ordered. Meat patties are packaged in spaced positions along a plastic strip and then frozen. The strips are packed in shipping and storing containers that are received by the automatic sandwich preparation equipment. The meat patties are removed from the strip by directing the strip over a small diameter roller that frees the patty. Two face-to-face plastic strips may be heat sealed to form pockets for the meat patties and also for serving portions of other sandwich components such as chopped vegetables, catchup, mustard and the like. The contents are removed by physical separation of the two strips. In another arrangement, ground meat is formed into a log shape that is frozen. While the log remains frozen individual meat patties are sawed from the log.
