Abstract
This invention relates to a sensor device able to provide, without contact, an exact indication of the tension in the free portion of each individual thread which leaves the rotating head of a stranding machine in order to contribute to the formation of a rope.
Claims8
A device for sensing the tension of threads in a rotating head of a stranding machine of the type in which thread is fed from a plurality of reels provided with tension regulating means and having a free portion for the thread on the rotating head, said device comprising a sensor for sensing spacial deflection of said free portion at a predetermined angular position of the rotating head, a means for activating said sensor when a thread is in a position corresponding to said angular position of the rotating head, and a control means capable of responding to a signal produced by the sensor corresponding to said spacial deflection.
A device for sensing the tension of moving threads in a rotating head of a stranding machine, the stranding machine being of the type in which thread is fed from a plurality of reels provided with tension regulating means and the threads having a free portion which deflects radially outward under centrifugal forces by the rotating head, the device comprising a sensor for producing a signal corresponding to radial deflection of the free portion of a thread at a predetermined angular position of the rotating head, a means for activating the sensor at said predetermined angular position, and a control means capable of responding to said signal.
