  • Patent number: 6116132
    Abstract: A cutter for cutting a laminated sheet such as tapes or the like or for shaping or chamfering tape end into various rounded configurations, a method of making such a cutter and an apparatus for shaping and cutting tape end. A sheet metal is worked to form integrally stationary and movable cutting blades which are connected to each other through a pair of connectors. A gap is formed between a stationary cutting edge of the stationary cutting blade and a movable cutting edge of the movable cutting blade. When a resistance force is exerted between the stationary and movable cutting blades on cutting self-adhesive tape with release paper, the resisting force is counteracted by a tensile strength in the connectors and a buckling strength in flexible portions such that the proper gap between the stationary and movable cutting edges will not be changed by the resisting force.

  • Patent number: 6112631
    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.

  • Patent number: 6030135
    Abstract: In a tape cutting mechanism, when a tape is cut manually, a rack 58 which is lowered by pushing a push button 14 down meshes with a gear 48 by guidance of a guide groove 59 to thereby cause a scissors cam 46 to make a single complete rotation along with a pin 46b around a cam shaft 47. The pin 46b half rotates to raise a turnable arm 52b up so that a turnable blade 52a is turned toward a fixed blade 55 to cut a printed tape portion. By the remaining half rotation, the turnable arm 52b is returned to its reference position. When the rack 58 rises with the resiliency of a compression spring 57 due to release of the push button 14 from its pushed state, the rack 58 is disengaged from the gear 48 with the guide of the guide groove 59.
