ABSTRACT:
Apparatus for punching regularly-spaced apertures in film or tape includes a rotary ring carrying a plurality of radially-extending punches, a further rotary ring carrying a plurality of dies and a drive ring outwardly of the punch-carrying ring which is mounted eccentrically of the punch-carrying ring and serves to force the punches at a punching zone into corresponding dies and thereby punches the required apertures in the film or tape.
To avoid damage to the surfaces of the film or tape infeed and outfeed guides are provided for directing the film along an in-feed path initially parallel to the axis of rotation of the punch ring and turning the film or tape about one of the guides rotatable about an axis approximately 17.degree. to the horizontal and in a plane at right angles to the axis of rotation of the punch ring. The out-feed guide is rotatable about a similarly inclined axis.
