  • Patent number: 5271488
    Abstract: A friction material facing (20) and carrier (11) assembly in which the facing (20) is secured to the carrier (11) by a plurality of concentric circular stripes (24A, 24B, 24C) of adhesive (24). Each stripe (24A, 24B, 24C) is interrupted at a single point on the circle to form a gap (25A, 25B, 25C) between the beginning and end of each circle of adhesive. The end of one circle may be joined to the beginning of the adjacent circle so as to form a continuous stripe of adhesive (24) from the inner margin to the outer margin of the facing (20).

  • Patent number: 5199540
    Abstract: A friction material and carrier assembly for a clutch driven plate, the assembly being intended for rotation about an axis and comprising a carrier (4), first and second arrays of friction material (20, 22) disposed on opposite sides of the carrier (4) each array of friction material being disposed about a respective locus substantially centered on the axis. The first and second arrays of friction material are secured to the carrier by means of first and second adhesive bonds, respectively. The second adhesive bond (24) is of elastomeric material providing resilient cushioning relative to the carrier (4) (in an axial direction of the assembly) for the second array of friction material (22), and the first adhesive bond (23) is substantially non resilient providing no or substantially no cushioning relative to the carrier (4) (in an axial direction of the assembly) for the first array of friction material (20) than is provided by the second adhesive bond for the second array of friction material.
