Apparatus for the manufacture of pipes and tubular bodies from roving strands soaked with synthetic resin
Abstract
Abstract AN APPARATUS FOR MANUFACTURING PIPES OR TUBULAR BODIES FROM ROVING STRANDS SOAKED WITH SYNTHETIC RESIN WHICH COMPRISES A WINDING CYLINDER DRUM ROTATABLY MOUNTED IN THE APPARATUS ON WHICH ROVING STRANDS IMPREGNATED WITH LIQUID SYNTHETIC RESIN ARE WOUND. THE ROVING STRANDS ARE SUPPORTED ON A CARRIAGE WHICH IS RECIPROCALLY DRIVEN BY A SCREW SPINDLE ALONG A PATH PARALLEL TO THE LONGITUDINAL AXIS OF THE WINDING CYLINDER DRUM. THE CARRIAGE HAS AN IMPREGNATING BATH AND THREAD GUIDING MEANS, BOTH OF WHICH ARE PIVOTALLY MOVABLE MOUNTED ON THE CARRIAGE AND MOVE IN ACCORDANCE WITH THE FEEDING DIRECTION OF THE ROVING STRANDS FROM THE CARRIAGE TO THE WINDING CYLINDER DRUM. THE IMPROVEMENT COMPRISES MEANS FOR COORDINATING THE TRANSLATIONAL MOVEMENT OF THE CARRIAGE AND THE ANGULAR POSITION OF THE PIVOTALLY MOUNTED IMPREGNATING BATH AND THREAD GUIDING MEANS WITH THE ROTATIONAL MOVEMENT OF THE WINDING CYLINDER DRUM.
