Apparatus for continuously molding cylindrical blocks of foamed polymeric material.

摘要

An apparatus (10) for making cylindrical polyurethane foam blocks, including an upstanding trough (12) with a weir structure (32) at the upstream end of a fall plate (14) in a molding apparatus (10), means for passing a first web (44) of a separation sheet below the trough (12) and between a gap (50) formed between the weir (32) and the fall plate leading edge (43), means (52, 54) for forming the first web (44) into a U-shaped configuration as it advances with the foaming material, and second means (56, 58) for feeding opposite webs of sheet material immediately upstream of the conveyor through molding means (63) forforming the cylindrical block.
