Abstract
A device for folding sheets of a medium is provided. The device has a frame; a cam mechanism attached to the frame; a lever attached to the frame, the lever being actuated by the cam mechanism; a first scissor arm attached to the frame, the first scissor arm being actuated by the lever; a pair of first rolls, one of the first rolls being movable by the first scissor arm; a second scissor arm attached to the frame, the second scissor arm being actuated by the lever; a pair of second rolls, one of the second rolls being movable by the second scissor arm; and a crease blade for contacting the sheets to create a crease in the sheets. Rotation of the cam mechanism through a first period of rotation causes the crease blade to move in a contact direction to create the crease in the sheets by pushing the sheets between the first rolls. Rotation of the cam mechanism through a second period of rotation causes the crease blade to move in a retracting direction away from the sheets and causes the lever to move the first and second scissor arms such that the first pair of rolls is separated and the second pair of rolls is separated.
