SW Spiral Winders

The winding head of the SW Spiral Winders has both winding capstans driven The winding table moves along the bed of the machine so that the winding belt can move clear of the last ply as more plies are added One capstan is tensioned via air cylinders in order to provide constant winding belt tension. This also offers a safety-release should the operator’s hand go too near a probe switch located in the nip of the winding belt The winding belt is completely enclosed and interlocked. A safety switch is mounted in the nip of the plies and another safety switch lies across the wet plies The main drive is via an infinitely variable speed ac motor with controls which are mounted on a convenient pendant
