An apparatus for the automatic feeding of a carrier to a laminating station. The apparatus has a gripper device which is fastened to two guide rods and which is movable t o anf fro horizontally. Each of the guide rods is guided in a linear guide and is mounted in supports which are connected to one another by means of an angular cross-strut. A pneumatic cylinder is articulated centrally to the angular cross-strut by a lengthened piston rod. The gripper device grips the carrier at a predetermined distance (Xmin) from the front edge, to transport it in the direction of a laminating station. A sensor for detecting the front edge of the carrier which is transported into the gripper device is located on a holding bracket fastened to a displaceable holding block. The upper and lower gripper strips each have a perforation in the center of their bevelled strip part. As soon as the front edge of the carrier interrupts the vertical beam path, the sensor generates a control pulse which closes the gripper device and which retains the carrier for the transport to the laminating station. |
