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.Field of SearchFEMALE MOLD AND MEANS TO FEED MEASURED CHARGE OF FLUENT MATERIAL THERETOPlural separate and distinct feeders Means to move feed means to female mold Traveling female mold Drawer type feed coacting with mold having movable bottom SETS OF PRESS COUPLES COMPRISING REGISTERING FEMALE MOLD CAVITIES Traveling female mold Including positive means to eject product Means to sequentially move female mold | |
