ABSTRACT:
In a line printer, form trimming apparatus for automatically separating paper-drive edge perforated tear strips from a continuous paper form comprises a trimmer having hold-down sections which include slots for receiving the sprocket of a paper driver to permit those sections to hold the edge perforated strips against the sprocket to enable the sprocket to draw the form past a print head. A ramp extends at an acute angle from the hold-down sections to ramp the center section of the form upwardly and away from the tear strip. The ramp includes an edge that projects below the level of the hold-down section to facilitate automatic separation of the tear strips from the center section of the form as the form passes through the line printer.
