摘要： PURPOSE:To manufacture the threadless coupling having resistance against the penetration of concrete, etc., by forming the tongue and corresponding groove in the opposite two sides of the rectangular blank material, by boring the setscrew holes near the another couple of opposite sides, and by bending this blank material into a tubular shape by fitting the tongue into the groove. CONSTITUTION:The tongue 4 is formed in one of a couple of opposite sides of the rectangular blank material 6 and the groove 5 fittable to this tongue 4 is formed in another side; the setscrew hole 2 engageable with the setscrew 11 is tapped near the another couple of opposite sides; additionally, the cantilever type spring pieces 1, 1 are formed. This blank material 6 is bent into a tubular shape by fitting the tongue 4 into the groove 5, and the coupling 9 is obtained. The pipes 10, 10 to be jointed, are inserted into open mouths on both sides of this coupling, and the setscrew 11 is screwed into the setscrew hole 2 so as to press with its tip the free end of the spring pieces 1, 1; hereby the pipes 10, 10 are tightened and jointed. Hereupon, the gap between the pipe 10 and the coupling 9 is covered by the spring piece 1, so that the penetration of the concrete mortar is prevented.

摘要： PURPOSE:To prevent the biting of cut end faces each other by retreating a hoop material after obtaining a product, pressing the cut end of the product with the leading end face of the hoop material thereby progressively feeding these. CONSTITUTION:When a connecting fulcrum shaft 6 is in the position (a) of the figure, the root of a rod 10 for controlling clamping abuts on the raised part 9a of a cam disc 9, and projects a clamp projection 11, thereby clamping a hoop material X. As the clamp discs 5 rotated, hoop material feed pieces 8 move in the feed direction, thereby feeding the hoop material X. When the connecting fulcrum shaft 6 positions to (d) of the figure, the root of the rod 10 abuts on the small raised part 9c of the cam disc 9, and the clamp projection 11 abuts on the hoop material X, thereby retreating the hoop material X by a slight extent (width of projection 13). Hence, the product 4 is smoothly pulled back by the retreat of the hoop material X making the hoop feeding possible.
