Abstract

1527768 Punching apparatus MASCHINENFABRIK GOEBEL GmbH 12 Dec 1975 [14 Dec 1974] 51063/75 Heading B4B A punching device for punching holes in sheet material, e.g. paper, comprises a punching tool 11 having a plurality of punches 10 and a diemember 8 having at least two series of apertures 9 of the same cross-section and spacing as the punches, the punching tool and apertured member 8 being adjustable so that, on relative movement, the punches are co-operable with the holes of a different series to effect punching of the material. As shown the die member 8 is clamped between two plates 2, 3 releasably secured to a shaft 1 by screws 4, 5. The apertures in the die member are spaced apart a distance 12 which is half that of the spacing 60 of the punches thereby producing two series of working apertures. In operation, when one series of apertures is worn, the plates are loosened to allow the die to be rotated to bring the second series into alignment with the punches. Alternatively, the disc 11 can be rotated to align the punches with the second series of apertures. The cross-section of the punches may be circular, square or triangular.
