<p>An ejection station in a machine for cutting flat workpieces, comprising gripper bars operating in their upper surface, the station comprising a perforated board which is raised by a first control device in order to bear a flat workpiece held by the grippers, the waste from the workpiece being gripped and then conveyed downwards by upper and lower telescopic needles belonging respectively to an upper ejection tool and a lower ejection tool movable vertically by a second and a third control device, characterised in that only the downstream edge of the perforated board is raised, so as to pivot around its upstream edge. The station characterised in that the downstream edge of the board is raised by angular rotation between 1 and 6 deg., preferably between 2 and 4 deg. The ejection tools are skewed parallel to the raised perforated board, and in that they slide along sloping guides at right angles to the board. <IMAGE></p> |
