  • Patent number: 5067217
    Abstract: An open ended, flat spiral belt is joined at its ends on a roll to form an endless cover. A spiral belt is fitted with a zipper assist in the seam area to facilitate the joining of the spiral belt on the roll. One part of the zipper assist is removably attached to one end of the spiral belt with the other part of the zipper assist being removably attached to the other end of the spiral belt. When the two sections of the zipper assist are zipped together, they pull the two ends of the spiral belt together, allowing for interdigitation of the spiral loops of the spiral belt, which then forms a channel for the introduction of a seam wire. Once the spiral belt is seamed on the roll, the zipper assist is removed and the roll is set in slow motion at about ten revolutions per minute. The entire fabric is subjected to application of heat from a hot air gun to set the spiral belt, now in the form of a spiral shrink sleeve.

  • Patent number: 5065511
    Abstract: A sinusoidally extending groove is cut into the jacket of a roller having a smooth surface to extend in circumferential direction thereof. A flat wire is thereafter placed into the groove. Then, a first saw-tooth wire is connected to one side of the flat wire and wound around the roller. The first turn of the first saw-tooth wire is guided by the flat wire and the subsequent turns thereof are guided by the respective preceding turn. After the winding has been completed, the flat wire is removed and a second saw-tooth wire is wound around the opposite located section of the roller. For this winding, the first turn of the first saw-tooth wire is used as guide for the first turn of the second saw-tooth wire. This leads to an optimal distribution of the tips of the clothing on the roller and an improved quality of the handling or treating, respectively, of the fibres. The roller finds use in textile machines, e.g. carding machines, opening machines, scutchers, breaker cards, etc.

  • Patent number: 5063649
    Abstract: A roll assembly for use in calenders has a non-rotatable carrier which is surrounded by a rotatable and radially movable hollow cylindrical shell. At least one end of the shell is driven by a pair of gears one of which is mounted in an annular bearing member surrounding a portion of the carrier and the other of which is connected with the one end of the shell. The bearing member shares the radial movements of the shell relative to the carrier. To this end, the radial position of the shell is monitored by one or two sensors in the form of first cylinder and piston units, and the bearing member is adjustable by two second cylinder and piston units.

  • Patent number: 5060357
    Abstract: A self-loading controlled deflection roll for forming a pressure nip with another roll has at least one support shoe mounted in a stationary support shaft for controlling the deflection of the roll shell in the direction of the nip. At either end of the controlled deflection roll, a pair of opposed guide shoes are slidably mounted on the stationary support shaft to apply pressure against the roll shell to stabilize the position of the roll shell relative to the stationary shaft. At least one guide shoe on either end of the roll is equipped with a compensating piston to permit its face surface to move radially outwardly relative to the guide shoe support on the stationary shaft. The guide shoes slidably reciprocate in planes parallel to the plane of the nip through the longitudinal axis of the roll and provide opposed, equal stabilization forces at substantially right angles to the plane of the nip.
