A press for the continuous production of thin chipboard and fibreboards a heated, rotatable central pressing drum, which is mounted in a support arrangement which includes a plurality of interconnected support members and a plurality of pressure rollers, disposed around a major portion of the periphery of the drum. An endless steel belt is guided around the major portion of the periphery of the drum between the drum and the pressure rollers. The belt carries the material from which the boards are to be produced and can be tensioned. The material, a chip or fibre layer mixed with a binding agent is subjected to a surface pressure between the endless steel belt and the pressing drum, and to a linear pressure in the nips between the pressing drum and the pressure rollers. The axle of the drum is made radially adjustable relative to the axles of the pressure rollers, by so doing, it is possible for the press to be put into operation in its empty state, without causing damage to the drum, to the endless steel belt or to the pressure rollers. This is true even if very thin chipboards or fibreboards are being produced.
