  • Knife pen for program-controlled plotters
    Patent number: 5438896
    Abstract: An apparatus for cutting labels or other material in a program-controlled plotter comprising a blade affixed in a shaft which, in turn, is rotably held in a shell which can be mounted in a plotter. Advantageously, the blade is mounted so that the cutting point is not on axis with the center line, but trails slightly so that when the direction of travel is changed, the blade rotates to adjust to the new cutting direction.
