Abstract: A towel dispensing mechanism includes a frame upon which a quantity of paper is stored on a supply reel. An extending portion of paper pulled through an exit slot of the housing rotates a paper feed roller rotatably supported within the frame, causing an attached arm member to engage a knife assembly, and causing a pivoting cutting blade to move into engagement with the paper web after the roller has rotated to a predetermined position. The knife assembly is biased to allow restoration to a precutting position when the arm member no longer engages the knife assembly. According to a preferable arrangement, a vertically disposed intermediately disposed engagement element supported to the frame interconnects the arm member with the knife assembly. Biasing of the arm member causes the feed roller to rotate additionally a predetermined amount after the paper has been cut, thereby metering a predetermined amount of paper from the supply reel through the exit slot.
