  • Patent number: 5144792
    Abstract: A cage-type stranding machine includes a rotatably mounted supporting pipe (6) and radially outwardly oriented longitudinal webs (7) attached to the supporting pipe and distributed uniformly around its circumference, resulting in greater stiffness which permits higher rpm. Spool carriers (9) are rotatably supported by supporting shields (12), which are attached to the longitudinal webs. The supporting shields and the rotation axes (13) of the spool carriers are arranged at an angle to the supporting pipe to reduce the rotation circle diameter, which again permits an increased rpm in operation so that the production output can be increased.

  • Patent number: 4903473
    Abstract: A stranding machine, and a method for controlling same wherein a measurement device is utilized to measure the centrifugal forces of a spool of the stranding machine. The strand spool rotation rate is then regulated dependent upon the measured centrifugal forces. As the material is depleted from the spool, the spool rotation rate is increased while maintaining a centrifugal force reading within given perimeters.
