  • Method and apparatus for guiding a moving tape
    Publication number: 20050133660
    Abstract: Method and apparatus for guiding a moving tape having a tape edge parallel to a direction of motion of the tape wherein the tape is received tangentially on a curved surface having an edge. Force applied to the tape is increased as the tape drifts farther away from a nominal position so as to move the tape away from the edge of the surface. Lateral motion of the tape is dampened by breaking up an air-cushion between the tape and the curved surface.

  • Device having tension control means including a coil spring for controlling the tension in an elongate material
    Patent number: 6079658
    Abstract: A device in which an elongate material which can be wound in the form of a roll is driven in a transport direction. The device has tension control means for controlling the tension in the material when the material is driven, which tension control means comprise a flexible braking member which is passed around a braking drum. The braking member is formed by a coil spring which has two spring arms, one of which is movable in order to influence the braking force of the coil spring in dependence on the instantaneous tension in the material.
