  • Patent number: 9962849
    Abstract: An improved food slice stacker is coupled to a meat slicer to automatically stack the slices from the slicer. The stacker includes a frame with a pair of spaced apart parallel supports that support a sprocket roller with axially spaced sets of sprocket teeth and a pulley roller with a plurality of axially spaced pulley members. The pulley members are aligned with the sets of sprocket teeth. A plurality of slice transport chains respectively engage the sets of sprocket teeth and the pulley members. The sprocket roller is motorized to enable the chains to transport food slices. The pulley roller is monolithically formed of a friction-free material to provide smooth surfaces that reduce retention of food particles thereon during washing.

  • Patent number: 9770840
    Abstract: An improved food slice stacker that can be coupled to a meat slicer, to automatically stack the slices on food into stacks, wherein the stacker can be easily washed and sanitized to remove food particles therefrom. The stacker includes a frame with a pair of spaced apart parallel supports that support a transport mechanism. The transport mechanism includes a plurality endless transport chains, an integrally formed sprocket sleeve with sprocket portions that engage and drive the chains and an integrally formed pulley sleeve with a smooth surface an a plurality of pulley members that also engage the transport chains, wherein the sprocket and pulley sleeves are spaced apart from each other, and wherein the pulley sleeve engages the transport member. The pulley sleeve is integrally formed of a friction-free material so as to provide for smooth surfaces that substantially prevent retention of food particles thereon during washing.

  • Publication number: 20090217828
    Abstract: In order to simplify the assembly and to achieve an improved compaction, the unit for compacting hollow bodies, for instance for non-returnable bottles, comprises a roller which can be driven, (1) featuring a plurality of protruding elements and a non-driven counter bearing (9?, 9?, 9?) with at least one recess, and is constructed in such a manner that the protruding elements, upon rotation of the roller, temporarily and at least partly engage with the recess and a deflector (6) which is downstream from the counter bearing in a rotational direction of the operated roller. Said deflector features at least one recess in which the protruding elements of the roller (1) temporarily engage during operation, at least partially.
