  • Patent number: 5989116
    Abstract: A meat slicing apparatus is disclosed, wherein the apparatus is capable of high-speed slicing of meat having large skeletal bones therein. The apparatus has a blade composed of a steel alloy that is approximately 5 to 10 times greater in compression strength than typical steel. The blade has an involute shape for withstanding the stresses incurred when slicing through bones having compression near that of steel, e.g., pork loin bones. The meat slicer includes a mechanism for securing a position of a meat section to be sliced so that the meat section stays in place during a slicing process, thereby reducing the risk of misalignment of the meat section with the blade. Thus, without such misalignments, there is a reduction in blade failures, shattered bones, bone fragments, and bone dust. Also, the securing mechanism reciprocates between securing the meat section for slicing and releasing it sufficiently for indexing toward the blade between slicing operations.

  • Patent number: 5878640
    Abstract: A pair of numerically controlled feed devices are successively operated, with the second feed device taking over from the first feed device when two or more punching steps have been performed. A trailing row of punching tools performs the first punching step with respect to a fresh plate at the same time when a leading row of tools performs the last punching step with respect to the preceding plate. There are provided sensors to determine plate length and/or angularity of the late edges in order to enable a numerical control to compute correction data for correcting the feeding of the plate whereby punching through the trailing and leading edges of the lates is avoided.

  • Patent number: 5088364
    Abstract: To provide for efficient handling of stock material (40) and cut-off elements (41), which may be workpieces or cut-off wedges, by a cut-off saw, with miter adjustments, a positioning finger (21) is pressed against the stock material to engage the stock material against a guide plate or bar (19) prior to clamping the stock material in position for cut-off. After cutting of the stock material, the clamp (5) is released, and the finger is moved to a position ahead of the cut-off surface, and then longitudinally in feeding direction to a removal conveyor (28) so that the cut-off element is raked away by the positioning finger. After removal, the positioning finger is retracted out of the path of the stock material and, while new stock material is being fed, is longitudinally returned to the starting position to again align new stock material against the guide plate or bar (19).
