  • Patent number: 11758913
    Abstract: A method is provided of pressing an irregularly shaped, elongated loaf of an elastic material into a strand with a cross-section which is constant along its longitudinal extension. The method includes disposing the loaf in a form tube of the slicing machine, and determining basic data of the loaf before pressing, the basic data comprising at least physical basic data of the loaf before pressing. The method further includes determining a target length change of the loaf between an unpressed state and a pressed state, determining a target cross-sectional change of the loaf between the unpressed state and the pressed state, and pressing the loaf in the form tube in at least one cross direction to the longitudinal extension by a cross press stamp and in a longitudinal pressing direction of the form tube by a longitudinal press stamp, according to the target length change and the target cross-sectional change.

  • Patent number: 11731302
    Abstract: In order to avoid underweight of slices when slicing a loaf into slices, thickness adjustments specified for slicing are adjusted depending on different pre-known parameters, from loaf to loaf and/or from slice to slice within one and the same loaf, preferably also across the boundary between two loaves optimized as early as possible so that existing weight conditions with regard to actual weight of the slices are maintained, in particular no more underweight slices are produced and/or the minimum average weight of the slices required for the entire batch is maintained.

  • Patent number: 11731304
    Abstract: In order to be able to slice product pieces, whose cross-section varies along their length, into weight-accurate slices, after pressing to a uniform product caliber it is possible to measure these realistically in terms of cross-sectional area and length and not in a pumped up state of the machine. On the one hand, this is promoted by the fact that even before pressing, a cross-press stamp is set to a forming tube cross-section oriented to the unpressed product piece. On the other hand, this is promoted by the fact that after pressing, by lowering pressing force to a substantially lower holding force, it is possible to deform back the deformed, pumped up machine parts before measuring the product caliber.

  • Patent number: 11213037
    Abstract: A method for slicing meat loafs that have a cross section that varies across their longitudinal extension into accurately weighted slices, that includes the steps of bringing the loaf into a defined shape with a uniform cross section across its length inside a forming tube by pressing the loaf before it is sliced. The pressing is performed in a longitudinal direction and a transversal direction relative to the loaf in a predefined order and in particular in multiple pressing steps. The pressing may also comprise pressure relieving strokes for the purpose of reducing the force exertion for pressing, and for keeping the tissue structure of the loaf intact.

  • Patent number: 10492504
    Abstract: A cutting machine for cutting up meat strands whose cross section varies over a longitudinal extension into weight precise slices as fast as possible, and a method for slicing such meat strands. Two or more strands may be received adjacent to each other in a respective form tube and pushed against a separately adjustable stop plate, which is assigned to each form tube, independently from each other by a controlled longitudinal press plunger. The strands may be compressed in the longitudinal direction and a cross section of the form tubes may be reduced in a first transversal direction jointly and in a second transversal direction independently from each other. Thus, the respective meat strand may be transversally compressed to a constant cross section for slicing.
