Rectilinearly Reciprocating Knife Patents (Class 241/199.3)
  • Patent number: 8833684
    Abstract: A cutting unit for comminuting bulky feedstock and a device into which such a cutting unit is integrated. The cutting unit has a cutting chamber, which is arranged along a conveying direction and is formed by paired opposite cross walls and longitudinal walls. A knife for comminuting the feedstock can be moved transverse to the conveying direction across the entire cross section of the cutting chamber from one cross wall to the opposite cross wall. To also assure the complete cutting through of fiber-containing or film-shaped feedstock, a counter knife is arranged in the cross wall opposite to the blade of the knife which is stationary relative to the cutting chamber and which during the cutting process forms a cutting gap with the blade of the knife. The wall segment of the opposite cross wall is placed movable in the advance direction of the knife.

  • Patent number: 8635948
    Abstract: The present disclosure relates to a working unit or a device that includes a working unit of this type for processing foodstuffs. The working unit can be driven and made to rotate by means of a drive unit of said device. The working unit preferably has at least two working elements that are situated on a working axis and that act in the peripheral direction of said working axis. At least one of the working elements can be pivoted about the working axis in relation to at least one additional working element within a restricted pivoting angle. The pivoting mobility of the blades, which are preferably interspaced and positioned axially one above the other, permits said blades to be brought into a common radial resting position in order to fill the container with the product to be cut, in such a way that practically the entire container volume is exposed and can be filled.
