Title:
MACHINE FOR MANUFACTURING CUTTING PIECE FROM CHIP
Document Type and Number:
Japanese Patent JPS55128406
Kind Code:
A
Abstract:
A machine for producing thin shavings from chopped cellulose chips, in which the shavings are cut substantially in the fiber direction and have a large surface area relative to their thickness. The machine comprises a first part provided with at least one knife means and a second part provided with at least one anvil surface for the chips, the first and second parts being arranged for rotation relative to one another. The second part provided with the anvil surface comprises a center member having open, helical conveying channels for conveying the chips axially, while the first part provided with the knife means is in the form of a cylindrical ring which surrounds the center member and which closes said channels over at least a part of their axial length. The depth of the channels varies in the peripheral direction of the member, said channels being deeper at the leading edge thereof than at their trailing edge, as seen in the relative rotational direction of the member relative to the surrounding ring. The depth of the channels also suitably varies in the axial direction, said channels being deeper adjacent the inlet edge of the surrounding ring with respect to the chip flow than at the opposite edge of said ring.
