Abstract: A rotary moulding machine for biscuit dough of the kind comprising a pair of co-operating rolls defining the bottom of a dough hopper, one roll having an embossed surface for feeding dough downwardly and into contact with the surface of the other or moulding roll which is formed with moulding recesses, and a scraper blade mounted to bear against the surface of the latter roll so as to press dough into the moulding recesses and remove excess dough from the remainder of the surface, includes the improvement that the scraper blade is carried by a pivoted mounting capable of infinitely variable adjustment along a path which guides the mounting in a direction having at least a substantial vertical component and a biasing arrangement is provided which exerts a turning moment on the mounting about the pivotal axis so as to press the scraper blade against the surface of the moulding roll. The machine may include a detector for measuring the average weight of resultant moulded dough pieces either directly or indirectly and a power-operated device responsive to the output of the detector for adjusting the position of the mounting in accordance with variations in the average weight. The power operated device may be a servomotor and the path of adjustment of the mounting may be defined by a slot co-operating with a pin defining the pivotal axis, relative movement between the two being controlled by a rotary cam.
