The present invention relates to a device for the continuous manufacture of slabstock polyurethane foam comprising conveyor means (1), a mixing head (51) and means (6) for discharging the reaction mixture from the mixing head (51) onto the conveyor means (1). The device comprises moreover a start board (7)) a stop board, means for moving the start board (7) along the conveyor means at the beginning of a production run in such a manner that it obstructs the moving reaction mixture to thereby increase the height of the first portion of the produced foam, and means for moving the stop board at the end of a production run in such a manner that it pushes the foaming reaction mixture ahead to thereby increase the height of the end portion. In this way, no operator has to enter the foaming machine and the start and end profiles of the foam blocks are optimised.
