1. A folding device comprising:
a chassis having a feed opening through which a leaf of paper is feed in a feed direction, the leaf of paper having a first end portion and an opposite second end portion;
a first clamp having a pair of first clamping bars, a first pointed jaw is coupled to each of the pair of first clamping bars, the pair of first clamping bars are coupled to the chassis to move the first pointed jaws in a direction perpendicular to the feed direction between a first open position and a first closed position, in the first open position the pair of first pointed jaws are spaced apart to define a first opening that aligns with the feed opening of the chassis to receive the leaf of paper, in the first closed position the first pointed jaws clamp the first end portion of the leaf of paper;
a carrier rotatable coupled to the chassis relative to the first clamp; and
a second clamp having a pair of second clamping bars, a second pointed jaw is coupled to each of the pair of second clamping bars, the pair of second clamping bars are coupled to the carrier to move the second pointed jaws in the direction perpendicular to the feed direction between a second open position and a second closed position, in the second open position the second pointed jaws are spaced apart to define a second opening that aligns with the first opening and the feed opening of the chassis to receive the leaf of paper, in the second closed position the second end portion of the leaf of paper is clamped between the second pointed jaws,
wherein when the first pointed jaws are in the first closed position and the second pointed jaws are in the second closed position, the carrier is rotated in a first direction to rotate the second clamp relative to first clamp to form a first fold in the leaf of paper and the carrier is rotated in a second direction opposite the first direction to rotate the second clamp relative to the first clamp to form a second fold in the leaf of paper, the second fold parallel to the first fold.
