ABSTRACT:
The invention is relating to a press for compressing a powdery material to grains comprising a loosely arranged, rotatable annular, perforated mould supported and guided by a rotatable mould holder and by an axially displaceable supporting member which supports the mould at the end remote from the mould holder, the side face of a mould engaging the mould holder being urged by the supporting member with a given force against the mould holder in the operational position of the press in a manner such that during the operation of the press the mould is caught along by the mould holder owing to the force produced between the mould holder and the mould, whilst a rotatable roller is arranged in the mould whereby an uninterrupted channel is provided at least at the level of the side face of the mould engaging the drivable mould holder.
