Abstract: A system for producing blocks of open-cell, flexible polyurethane foam material and for conditioning each freshly-manufactured block to impart thereto optimal flexible foam properties. The system includes means to pour the flowable constituent of the foam material to be manufactured into a production station at the inlet of a conveyor, the constituents interacting to create on the conveyor a block of open-cell flexible foam material which is then wrapped in a plastic film casing that exposes the leading and trailing end of the block so that the encased block is open ended. The conveyor transports the wrapped block toward the rear end of a gate in a conditioning station having a port therein whose front end is coupled by an air duct to a suction fan.
