ABSTRACT:
The invention relates to a machine for manufacturing flat bodies in a continuous linear process. This is attained by the intermittent forward movement of the moulds on a closed circuit static runway, passing through the various operative steps for forming the pieces. The runway defines a rectangular trajectory and the moulds are square with bevelled vertices forming vertical channels for the actuation of centering elements. The moulds cover the totality of the circuit with the exception of two spaces at the diagonally opposed angles. Each straight section is provided with a pusher facing a buffer for the simultaneous and combined action until each mould reaches the end of the circuit. At a point of the circuit there is a fixed hopper beneath which there reciprocally moves a carriage bearing a metering hopper. Once the pieces have been formed they are removed by a pneumatic extractor having a multiple suction head.
