Abstract
Abstract Apparatus and method for covering cables with flexible thinwalled tubing for sliding fit, for use in such applications as pre-tensioning or post-tensioning concrete installations. The cable is coated with lubricant, and fed into a length of extended tubing from a nozzle to which the tubing is secured.
