ABSTRACT:
A printer having first and second opposed sprockets positioned on opposed sides of a printer platen for feeding from an upstream to a downstream direction continuous-feed paper sheets having continuous-feed edge strips formed along the opposing sides of the paper sheets. An edge strip trimming apparatus includes first and second edge strip trimmers. Each of the edge strip trimmers have edge strip hold-down devices positioned in closely spaced-apart relation to one of the first and second sprockets for holding the edge strip against the sprocket as the paper is fed through the printer. An inclined paper support bed extends inwardly from the edge strip hold-down device to a point underneath the horizontal plane of the paper sheet for progressively diverging the plane of the edge strip from the plane of the paper sheet as the paper sheets are successively fed through the printer. The support bed defines an edge surface. The edge surface extends downwardly, beneath the hold-down device, to ensure that each paper sheet is properly passed through the edge strip trimmer and separated from its respective edge strip.
