The invention relates to a method for the production and forming of food which is wrapped in foils prior to the final preservation as a protection against recontamination. The filled foils or foil bags, respectively, are aligned between plates which are provided with cavities. In order to achieve a uniform distribution of the fill material within the foil bags, the plates are first advanced towards each other. Upon a certain plate distance or internal pressure of the bag, the air between foil and cavity is drawn off through fine holes in the plate cavities. Thereby, the foil is stretched and pressed against the inner wall of the cavities. At the same time, the sausage meat is completely urged into the cavities by the further reduction of the plate distance so that the unformed foils are planely superposing each other. If the finished products are to be withdrawn individually from the packages, it is possible to seal the planely superposing foil areas through a fat and protein film. If packages are desired which enable the simultaneous removal of several products, gates are employed for maintaining the shape during further processing. |
