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.

Method of controlling a cage stranding machine for producing stranded material, having at least one rotatable stranding cage having a plurality of supporting means for holding a plurality of spools for the material being stranded and a removal device for the stranded material as well as a winding device, comprising the steps of:
- measuring the centrifugal force acting on the spool body of at least one spool with a measuring means including a force sensing pickup operatively associated with at least one of said supporting means and directly coupled to said at least one spool, and
- regulating the rotation rate of the stranding cage and the removal rate of the stranded material in dependence on the measured force value and a given constant value for the centrifugal force, with the ratio of cage revolutions to removal rate being kept constant in correspondence with the given length of lay of the stranded material to be produced.
In a stranding machine having at least one rotatable stranding cage configured for accepting a strand core and including a plurality of means for supporting a plurality of material holding spools, wherein said material is wrapped about said strand core to form finish stranded material, and means for removing the stranded material from said cage, the improvement comprising:
- means for measuring the centrifugal force acting on at least one of said material spools, and for producing a signal indicative of said measured value, said measuring means including a force sensing pickup operatively associated with at least one of said supporting means and directly coupled to said at least one of said spools, and
- controlling means for receiving said signal and for controlling the rotation rate of said stranding cage and the removal rate of the stranded material dependent on the measured value of the centrifugal force.
In a stranding machine having at least one rotatable stranding cage configured for accepting a strand core and including a plurality of means for supporting a plurality of material holding spools, wherein said material is wrapped about said strand core to form finish stranded material, and having drive means for rotating said stranding cage and means for removing the stranded material from said cage, the improvement comprising:
- means for independently measuring the centrifugal force acting on each of a plurality of said material spools, including a number of force sensing pickups, each operatively associated with a respective one of said supporting means and directly coupled to a respective one of said spools,
- coordinating means connected to said measuring means for producing a control signal indicative of the greatest measured centrifugal force, and
- controlling means connected to said driving means for receiving said control signal and for controlling the rotation rate of said stranding cage and the removal rate of the stranded material dependent on the measured value of the centrifugal force.
