<p>In a pushing type pipe-manufacturing-apparatus in which a tubular body, which is formed by spirally winding a strip-like member is fed out by said strip- like member continuously supplied to the rear of said formed tubular body, its mechanism can be simplified, a diameter of the tubular body can be made constant, and a weight of the machine frame is reduced. A tubular body R is molded by arranging a joining roller part 4 made of an outer roller 2 and an inner roller 3 at a closed portion of a strip-like member 100, and an outer peripheral regulating frame 6 fixed at a machine frame 1 holding the joining roller part 4 across the outer roller 2, spirally winding once along the continuously supplied strip-like member 100 to a first closed portion H and regulating an outer peripheral length of the tubular body R is arranged.</p> |
