ABSTRACT:
An apparatus for the perforation of tracks of goods which are transportable approximately in their plane, particularly of thermoplastic synthetic material foils, with at least one sleeve-shaped punching tool which is moveable back and forth relative to the track of goods perpendicularly to the plane of transportation and parallel to its longitudinal axis, with a coaxially arranged pin which engages in the hollow punching tool for discarding the stamping cuttings, with a carrier of the track of goods arranged on the side of the track of goods which faces away from the pin, the carrier extending crosswise to the direction of transportation, and a carrier of the pin arranged parallel to the carrier of the track of goods and extending over its entire width. The carrier of the pin which serves as the ejector of the stamping cuttings carries the punching tool beyond the pin. The carrier is moveable, parallel to its longitudinal axis in a forward stroke with a velocity exceeding the accelerated rate of gravity, toward the stationary carrier of the track, and the ejector pin is coaxially guided in the punching tool and is freely moveably mounted limited therein with such an axial play that the ejector pin is able to push the stamp cuttings out of the punching tool.
