Abstract
PURPOSE:To mold a flexible pipe easily and efficiently, by superposing a right screw of band steel to be wound at first, on a right screw of a core shaft, and after that, rotating the pipe to the left, which is opposite when seeing from the rear of the core shaft, also stopping the rotation of the pipe in its front, and feeding out the pipe which has been wound around the core shaft and molded. CONSTITUTION:A rotary frame 2 is rotated by a gear 4, simultaneously a rotary shaft 15 is also rotated, also rollers 6, 6' are rotated, and metallic thin band steel B wound around a bobbin 8 is drawn out. Subsequently, when the band steel B is being drawn out, it is bend-shaped in each opposite direction in the waveform or width direction, is fed to a circular arc-like induction plate 7, and the band steel B is formed like a circular arc while it is passing through this induction plate 7. In this case, one side of the circular arc-like band steel B is compressed, the other side is expanded, is led so as to be vertical to a core shaft 22, and is superposed by making it out-of-phase. Subsequently, the compressed inside part and the outside are wound so as to be an inside layer and an outside layer, respectively, and when the frame 2 is rotated to the left and the superposed part of the band steel B is on the right screw, the core shaft 22 on which the right screw 21 has been spirally provided is rotated to the opposite left, a wound pipe A is advanced, rotation of the pipe A is stopped at a position of a chuck 25 provided in its front, and it is fed out by the core shaft 22 provided with the right screw 21.
