Abstract:
A process for the continuous production of polyurethane slabstock foam comprising the step of applying a polyurethane reactive mixture in the form of a liquid foam from a substantially rotationally symmetrical source onto the conveyor belt of a slabstock foam plant and distributing the liquid foam transversely across the width of the conveyor belt by a distribution device arranged above the conveyor belt, thereby forming a distribution slot, wherein said distribution device is in the form of a plate, the surface of said plate comprising a material which has self-releasing properties towards the polyurethane reactive mixture, wherein said plate is arranged obliquely at an angle of 20 to 60.degree. relative to the conveyor belt center line, wherein the portion of said plate upstream of said conveyor belt is further away from said conveyor belt and the portion of said plate downstream of said conveyor belt is closer to said conveyor belt.
