Abstract

THE METHOD ACCORDING TO THE INVENTION COMPRISES PREPARING A POLYMERIZABLE REACTION MIXTURE CONTAINING A BLOWING AGENT, APPLYING THE REACTION MIXTURE ONTO MOVING CONVEYOR MEANS (7,10) AND ALLOWING A FREE RISE EXPANSION AND POLYMERIZATION OF THIS REACTION MIXTURE WITHIN A SUBSTANTIALLY HERMETICALLY CLOSED SPACE (17). THE PRESSURE IN THIS SPACE IS MAINTAINED WITHIN A PREDETERMINED PRESSURE RANGE BY CONTINUOUSLY SUPPLYING GAS INTO SAID SPACE, IN ADDITION TO THE BLOWING GAS PRODUCTION, AND BY SIMULTANEOUSLY EXHAUSTING GAS FROM SAID SPACE. IN THIS WAY, PRESSURE FLUCTUATIONS MAY BE REDUCED IN SAID SPACE AND FURTHER PARAMETERS SUCH AS THE TEMPERATURE CAN BE CONTROLLED SO AS TO ENABLE PRODUCE A FOAM WITH CONSTANT PROPERTIES. THE INVENTION ALSO RELATES TO A DEVICE COMPRISING A SUBSTANTIALLY HERMETICALLY ENCLOSED CONTINUOUS POLYURETHANE SLABSTOCK FOAM PRODUCING MACHINE (1) FOR PREFORMING THE METHOD ACCORDING TO THE INVENTION.
