ABSTRACT:
Preferably for use in the production of continuous lengths of rigid foam, a molding machine employs opposed endless conveyor belts having adjacent linear runs forming therebetween a molding zone. Each of the conveyors is supported for movement toward and away from the other conveyor, and one of the conveyor supports is made up of a plurality of sections hingedly connected together to locally yield to a lump or other discontinuity in the product being produced. Double acting expansible chambers are provided to drivingly interconnect the conveyor supports for separating the conveyors, permitting the conveyors to come together, and for clamping the conveyors together under a pressure sufficient to resist the foaming pressure, with a space between the conveyors being maintained during molding by adjustable spacer blocks. Micro-switches sense the minimum spacing to permit the clamping pressure to be applied and to release the clamping pressure when a lump or other discontinuity moves a conveyor section off of its spacer block.
