Abstract
An improved cable conveyor system in which buttons provided for pushing the conveyed material are fitted with bearings to relieve the cable of torsional stresses. As a cable is tensioned, torsional stresses are incurred, tending to unwind the braided wire. By providing an opportunity for the cable to unwind, stretching may be carried out without the usual unrelieved torsional stresses.
