  • Patent number: 6284074
    Abstract: A method of manufacturing a bonded friction product, such as an automobile brake shoe, and apparatus therefor, includes forming a plastic inner lining element of uncured or green thermosetting resin binder containing friction modifiers and reinforcements and bonding the element to a shoe platform by way of an adhesive resin in a heat and pressure regime which cures the resin binder and adhesive. The need for a closed mold and/or venting stops is avoided by a stabilizing press (50) which includes a heated bed (53) between guide plates (56, 57) that has a recess (52) of less thickness than the lining element (16) to receive such lining element in its green state. The guide plates are spaced slightly further apart than the width of a shoe platform which is, having been preheated, brought down onto the lining element and pressed by a pneumatic ram (70), the loosely sliding shoe body (11) comprising a non-sealing closure member of the press.
