  • Patent number: 7788885
    Abstract: A method is provided for loading stacked food product into packages. Open top containers are arranged in rows and movable into a loading station. A shuttle conveyor has a retractable and extendable conveying surface, the conveying surface having an end region extendable to a position arranged above the containers of a row of the containers. A guiding and pushing apparatus is arranged above the row and includes guides that are lowered to capture a row of stacked food products on the conveying surface, and plungers within the guides that lower and press a top of the stacks. When the conveying surface is retracted from beneath the guides and the row of containers, the guides are lowered further, adjacent to the containers, and the plungers are lowered with respect to the guides to push the stacks into the containers.

  • Patent number: 7278344
    Abstract: A slicing machine includes a machine frame having a food loaf delivery path arranged in a longitudinal direction, and a cutting assembly arranged in the delivery path. The cutting assembly has two longitudinally directed reciprocating blades facing upstream in the delivery path. In operation, the loaf is pressed through the cutting assembly which cuts the loaf into quarter sections. A slicing blade is arranged in the delivery path downstream of the cutting assembly, the slicing blade arranged to slice the sectioned food loaf transversely to the longitudinal direction.

  • Patent number: 5026038
    Abstract: Signature loader comprising a telescopically related main floor-mounted frame and a smaller auxiliary frame, first and second horizontal rotatable shafts between the frames spaced apart by a predetermined distance and so positioned that infeed belts thereon converge to define between them a signature infeed throat, one of said shafts being a pivot about which the auxiliary frame may be pivoted so the throat may be selectively positioned in one of two alternate attitudes.

  • Patent number: 4907791
    Abstract: A sheet feeder has a supply station wherein signatures fresh from the printing press are stacked. The stack is supported such that the signatures are in an arched, non-planar configuration. A sheet stripper extracts signatures successively from the stack and feeds them in a constant stream to a transfer conveyor. The stripper grips the sheets with a suction device which applies a constant but locally intermittent vacuum. The transfer conveyor carries the signatures to a delivery station. The delivery station includes fingers which arch the signatures. Arching the signatures in the supply and delivery stations prevents rolling of the signatures.

  • Patent number: 4570535
    Abstract: Stacking and strapping machines for magazines in which the turning axes for the conveyors which move a stack to be strapped are positioned to enable the stack to be boxed in while being strapped, the conveyors having pushers which in part enable this to be done in cooperation with fixed stops at the strapping station.
