  • Patent number: 11833706
    Abstract: A bread slicer includes an infeed side and a hollow infeed assembly positioned in the infeed side, the infeed assembly having an open end and a closed end defining a chamber for receiving bread to be sliced. The bread slicer further includes a pusher for pushing the bread to be sliced along the infeed assembly, and a linkage connected to the pusher, the linkage adapted to move the infeed assembly from a bread receiving position to a predetermined position of a bread path, the linkage adapted to then move the pusher and the bread to be sliced along the bread path from the predetermined position to a delivery area. The bread slicer further includes slicing blades having sharp edges to slice bread moving along the bread path.

  • Publication number: 20230271342
    Abstract: A cartridge adapted to secure reciprocating bread slicer blades including a rectangular frame having a planar surface, the frame having a plurality of pairs of opposed holders, each pair of the opposed holders adapted to releasably secure opposed ends of a corresponding bread slicer blade. The frame is adapted to secure a plurality of aligned bread slicer blades defining a plane offset from the frame planar surface. The frame is adapted to selectively maintain each of the plurality of aligned bread slicer blades in tension.

  • Publication number: 20150202831
    Abstract: A packaging machine for a food product includes a folding arrangement that reconfigures a first sheet of packaging material from a planar configuration to a non-planar configuration, a supply arrangement supplying a second sheet of packaging material in a planar configuration, a first heat sealing arrangement that heat seals side edges of the first sheet to side edges of the second sheet, a cutting arrangement that cuts the first and second sheets into preselected lengths, thereby providing the sheets with first and second ends, and a second heat sealing arrangement that heats corresponding ends of the sheets with one another, such that the second sheet of material is in the substantially planar configuration when heat sealed to the first sheet of packaging material by the second heat sealing arrangement.
