  • Patent number: 9943938
    Abstract: A method for making a friction plate that includes a core plate and a friction facing is disclosed. The method includes cutting a pattern of friction material segments into a friction material sheet such that each friction material segment remains integrally connected to the friction material sheet, locating a predetermined number of the friction material segments adjacent to a surface of a core plate to which a bonding material is present, separating the friction material segments from the friction material sheet, and placing the friction material segments onto the surface of the core plate over the bonding material. An apparatus for practicing this method is also disclosed.
    Type: Grant

  • Patent number: 6790308
    Abstract: A method and apparatus for making a friction clutch plate includes cutting a supply of friction material into a plurality of individual shaped segments. The cut segments are moved in a first horizontal linear direction to a position adjacent a shuttle assembly. At least a first cut segment is engaged by the shuttle assembly which transfers the first cut segment in a second horizontal linear direction which is substantially perpendicular to the first horizontal linear direction. The first cut segment is deposited in a first indexing fixture. The remaining cut segments are sequentially moved in the first horizontal linear direction to the position adjacent the shuttle assembly. At least a second cut segment is engaged by the shuttle assembly and is transferred in a third horizontal linear direction which substantially perpendicular to the first horizontal linear direction.

  • Patent number: 6668891
    Abstract: A friction material has a plurality of connected sections defined by a plurality of notches therebetween. Each notch has an apex which compensates for tear and compression of the friction material when the friction material is circumferentially placed on a flat surface of an annular core plate. In certain embodiments, a multiple linked loading device places the notched friction material adjacent a core plate to form a clutch plate.
