Abstract: In a method for manufacturing a camshaft for an internal combustion engine a metal tubular element is expanded within a mold with the aid of a fluid at high pressure fed into the tubular element and with a simultaneous axial compression of the tubular element. The cams of the camshaft are formed in subsequent steps, starting from intermediate cams and ending with end cams. In a first step of the method, the intermediate cams are formed in a first mold. In a subsequent step, the end cams are formed within auxiliary molds which surround, only throughout a predetermined length, end portions of the tubular element which project from the mold which surrounds the already formed intermediate cams. In this subsequent step, the tubular element is compressed axially by axially displacing two clamp members, which grip and surround completely, throughout a predetermined length, the end portions of the tubular element which project outwardly from the auxiliary molds.

Abstract: A lateral pipe lining material having a flange on one end thereof is installed on a head collar which is hermetically mounted on a pressure bag that stores the lateral pipe lining material. The head collar comprises a curved section and a cylindrical section projecting from the curved section. An expandable member is mounted to the outer circumferential surface of the cylindrical section of the head collar, and expanded so that the outer circumferential surface of the expanding member comes into close contact with the inner circumferential surface near the flange, and the inner circumferential surface thereof comes into close contact with the outer circumferential surface of the cylindrical section of the head collar. This allows a hermetical connection between the lateral pipe lining material and the head collar and ensures a reliable eversion and insertion of the lining material into a lateral pipe.

Abstract: In a method and apparatus for manufacturing an optical fiber cable, a metal band is gradually shaped into a lengthwise slotted tube, the optical fibers are introduced into the still open slotted tube, the lengthwise slot of the tube is welded and the outside diameter of the welded tube is reduced. The welded tube with the reduced outside diameter is wound at least once around a take-up reel. A force provided on the reduced outside diameter welded tube as it is wound on the take-up reel causes an elastic strain of 0.1 to 0.6% on the tube. The strain is released on the take-up reel to produce an overlength of the optical fibers relative to the reduced outside diameter welded tube.

In the process of forming the impressions, rolling stands in the rolling apparatus first fashion a longitudinal, generally rectangular channel in the sheet corresponding to each strip as the sheet progresses through the rolling apparatus. At the same time, the strips are shaped into reinforcement elements having an extended, continuous portion and splayed legs extending outwardly from the edges of the continuous portion.

Abstract: An apparatus and method for continuously forming multi-layer metal pipe from at least two elongated sheets of metal. One sheet is impressed with longitudinal corrugations in a rolling device and the second sheet, being uncorrugated, is then positioned contiguously upon the first, forming a multi-layer sheet. One or more removable modules is mounted in the rolling device to accurately align and guide the second sheet into position upon the first. Complementary portions of a single corrugation are then formed in the marginal edges of the multi-layer sheet and the sheet is spiralled into adjacent, helical convolutions in a pipe forming device, with the uncorrugated sheet forming the pipe interior. The adjacent convolutions are joined in a helical seam in the single corrugation by a seaming device located in the pipe forming device. In the primary embodiment of the invention, the seam is formed as a double lock seam along a neutral axis of the single corrugation.
