Cable feeding apparatus and method |
摘要 |
An improved cable feeder uses tractor type drive belts and compressed air to propel cable through a conduit. The axial force applied to the cable is sensed with a strain gauge near the conduit or a pressure detector in a hydraulic system powering the drive belts. If excessive force is applied, hydraulic fluid is diverted from the drive belts. The radial force applied to the cable is limited by a calibrated spring. The feeder can also be arranged in a mid-assist configuration. Conduits and the cable are sealed to maintain air pressure. A by-pass pipe is provided to convey pressurized air from a first conduit to a succeeding conduit.
