Abstract
Abstract Frozen meat slabs or the like are subjected to the constantly rotating action of a blade provided with a single convolution having a helical cutting edge for severing the slab into elongated strips whose widths are essentially the same as the distance which the slab is advanced during each revolution of the blade, and to the action of a gang of constantly rotating, peripherally sharpened discs which slice the strips into polygonal pieces, e.g., cubical, for further processing, as in stew. Each transverse kerf produced by the blade is initially concave and is progressively increased in depth and in length toward both side edges of the slab while the latter is firmly supported therebeneath by an anvil along which the blade helix causes the slab to slide continuously. The final cutting action for producing each strip is in the form of a shear during which the cutting edge of the blade acts in point contact with a concave, terminal shear edge of the anvil, causing the severed strip to fall away from the slab. The descending strips are intercepted and successively forced forwardly into the bank of discs, without interruption, along an arcuate course, in the same general direction as the path of travel of the slab, by a lobed feeder interleaved with the discs and rotating continuously about an axis parallel with the axis of rotation of the discs but in a direction opposite to the direction of disc rotation.
