Machine for manufacturing flat bodies in a continuous line

Machine for manufacturing flat bodies in a continuous linear process comprising, a closed circuit static sliding runway having four interconnected rectilinear sections connected together to form a rectlinear closed circuit, each rectilinear section having a head end and a tail end which is opposite from the head end, a plurality of substantially quadrangular moulds each having at least one space for receiving material to form a piece to be molded, each space having a bottom for supporting the material, said moulds having dimensions which comprise a sub-multiple of the length of each rectlinear section with all rectilinear sections being completely filled with moulds except for opposite corners of said runway, each mould having bevelled vertices which, with the bevelled vertices of an adjacent mould in the runway form an angular vertical channel, feelers operatively connected to said runway for engagement in said angular vertical channels to center each mould on at least two of said rectilinear sections at a location corresponding to a press site where material in the space of each mould is to be pressed, a pusher mounted at the head end of each rectilinear section, each pusher having a cylinder with a stroke which is at least equal to a dimension of moulds in the rectangular section serviced by that pusher, for pushing all moulds in the rectangular section serviced by that pusher, for pushing all moulds in that rectangular section in a linear passage along that rectangular section, a buffer mounted at the tail end of each rectangular section and cooperating with the pusher of that rectangular section for receiving moulds pushed by the pusher, each rectangular section having its own pusher plus buffer pair, each buffer having a cylinder for withdrawing the buffer as the cylinder of the pusher extends the pusher for synchronizing movement of the pusher plus buffer pairs for moving the moulds along the rectangular sections in the linear passage, and a microswitch operatively connected to each of the cylinders of the pusher plus buffer pairs for activating a cylinder plus buffer pair which is downstream of a previously activated pusher plus buffer pair after the moulds of the previous pusher plus buffer pair have been moved along their respective rectangular section.
