Abstract: Braided plastic sleeving useful in electronic applications is readily cut by means of a hot wire which is advanced through the sleeving when in flattened form at a controlled rate. It is important that the sleeving be under tension at the location where the cut is to be made. The size of the heated wire and the rate of advance of the heated wire through the flattened braided sleeving relative to the size of the braided sleeving is important to obtaining cutting and sealing of the ends of the braided sleeving without welding the ends shut. Means and method for achieving this is described herein.

Abstract: An apparatus for removing the bead wires from a scrap tire having a pair of overlapping and counterrotating shearing members mounted on a movable carriage. The carriage provides reciprocating motion to the shearing members between two shearing work stations. While shearing action takes place at a first work station a scrap tire is fed into the adjacent work station, whereafter the bead wires of the scrap tire are first elongated and then compressed into overlying adjacent positions. Advancement of the shearing members into the tire produces a first tire shear that is at least closely tangential to the bead wires. When the pinch point of the shearing members is proximate the bead wires forward movement of the carriage is ceased. However, the tire is caused to rotate about its axis by the shearing members to produce a second shear that is substantially concentric with the bead wires, the first and second shears being a single continuous motion.

Abstract: An apparatus for removing the bead wires from a scrap tire having a pair of overlapping and counterrotating shearing members and a movable carriage. The carriage includes a plurality of rolls positioned to fit within the inside diameter of a tire.

The compression force aligns the bead wires with a bead guide roll so that the crowding bar may be pivoted away from the subsequent shearing action, the bead wires then being crowded against the bead guide roll.

The film web is continuously advanced over at least a portion of the circumferential surface of a rotatable anvil roll, and tensioned against the anvil roll surface through the use of suitable tensioning devices, such as tension rollers arranged upstream and downstream of the anvil roll. At least one opening is formed in the circumferential surface of the anvil roll which is smaller than the size of the hole which is desired to be punched into the film web through the use of the inventive rotary tube punching arrangement. An annular groove extends about the hole in the surface of the anvil roll, forming a land between the hole and the groove.

Abstract: A wrapping film severing apparatus is disclosed for use in severing sheets of film from a roll of plastic film. The roll of film is supported so that it may rotate about its axis of rotation while film is being withdrawn from the roll.

Abstract: A cutter assembly (82) for cutting web material such as paper (80) includes a circular cutter (100) having an endless peripheral blade (102) mounted on a frame (92) on which also is mounted a tension roller in the form of a pulley (94). A smaller pulley (98) is mounted on and co-axial with the circular cutter 100, and a belt (96) is trained around the pulleys (94 and 98). The portion of the belt (96) on the tension roller (94) provides an engagement surface adapted to engage the paper (80) so that movement of the cutter assembly (82) causes rotation of the tension roller (94) and thus faster rotation of the circular cutter (100). This results in efficient cutting of the paper (80) and high cut quality because the tension roller (94) prevents bunching of the paper (80) in the vicinity of the endless blade (102).

Abstract: A method and apparatus for producing open-sided V-belts by cutting from a vulcanized, sleeve-shaped roll. The sleeve-shaped roll is disposed over two drivable rollers. A tensioning arrangement which includes one of the rollers has a weight. This weight acts solely on such roller tending to pull this roller away from the other roller. This tensions the roll. When the tensioning force attains a predetermined limit, it is partially counteracted by a force acting in the opposite direction. The counter-acting force is supplied by suitable means. Cutter means are provided for cutting the roll while it is tensioned and the counteracting force is increased by suitable means in dependence upon the number of belts cut from the roll.
