  • Patent number: 5493940
    Abstract: A cutter has a roller body which is made from a hollow profile-like inner part and a tubular profile-like outer part having an irregular cross-sectional shape. The outer part and inner part are such that the working flight circle of a tool on the body is approximately as near to an axis of rotation as the maximum outer circumference of the body. Apart from forming a mold core for the outer part, the inner part also forms a clamping body, and includes a supporting body and a balancing counterweight for the tool unit, thereby providing a very high cutter block strength, and at the same time, a low mass moment of inertia.

  • Patent number: 5433363
    Abstract: A plastic bag dispenser holds a continuous roll of bags, connected by perforated separation lines. The dispenser is provided with a tongue, which the bags are dispensed over, that engages the separation line between the bag at the end of the roll and the next bag. This begins the separation of the separation line, as well as holds the next bag behind the tongue. A finger is provided on the upstream side of the tongue, with a gap between the finger and tongue. As a bag is separated, a portion of the front edge of the next bag is held in the gap, holding the bag in position for the next user. The roll of bags rests in angled grooves in the dispenser that cause the roll to abut and frictionally engage an interior surface of the dispenser, preventing free-wheeling of the roll.

  • Patent number: 5400493
    Abstract: A bale debanding method and apparatus comprising a band breaking blade, a band winding mandrel and a mandrel cleaning plate are mounted to a frame. A support table is attached to the frame for receiving a waste paper bale that is held together by banding material. As the bale is moved past the band breaking blade, a band retention notch engages a band and by stretching it breaks the band. Once a band is broken, an extensible band catch extending out of the mandrel contacts the band and facilitates the band in being wound around the mandrel. Once all of the bands have been removed from the bale, the band catch is retracted to a position within the mandrel and a cleaning plate is moved axially along the mandrel sweeping the bands off a free end of the mandrel. This process is repeated to remove bands from other surfaces of the bale, thereby releasing the waste paper in preparation of processing.

  • Patent number: 5395025
    Abstract: A method and apparatus for imparting an angle cleave to a plurality of optical fibers. The cleaving device comprises a base having a support surface, the support surface having two lower pads which are aligned with two upper pads on a hinged cover, so that the fibers may be clamped between the respective pairs of lower and upper pads. One of the upper pads is designed to shift with respect to its corresponding lower pad; when a fiber is clamped between these pads and the upper pad moves, the fibers twist as a result of the induced torsional load. When the fibers are scored and cleaved while in the twisted state, the resulting end faces are at an oblique angle with respect to the fiber axes, which is beneficial since this reduces signal reflections at the fiber-to-fiber interfaces.
