Apparatus for continuously molding cylindrical blocks of foamed polymeric material |
摘要 |
An apparatus for making cylindrical polyurethane foam blocks, including an upstanding trough with a weir structure at the upstream end of a fall plate in a molding apparatus, means for passing a first web of a separation sheet below the trough and between a gap formed between the weir and the fall plate leading edge, means for forming the first web into a U-shaped configuration as it advances with the foaming material, and second means for feeding opposite webs of sheet material immediately upstream of the conveyor through molding means for forming the cylindrical block.
