    Abstract: Opposed straightening rolls are mounted within a U-shaped frame, their axes being parallel and at an angle relative to the longitudinal axis of the object to be straightened. One of the rolls is segmented into three separate rollers with the axes of the outer rollers eccentric to the axis of the center roller and adjustable along an arc. The points of contact between the rollers and workpiece are arranged to define a plane containing the longitudinal axis of the workpiece.

    Abstract: Tubular members, such as sections of tubing for use in millimeter waveguide systems, are straightened through the use of roller or rotary straightener apparatus. The previously common creation of helical indentations along the inner walls of the tubular members, which has been found to result from a discontinuous surface contact at discrete points between the tubular members and conventional straightening rollers, is avoided by the use of special-purpose rollers. The specialpurpose rollers are shaped such that the tubular members undergoing straightening maintain intimate surface contact with the rollers throughout a continuous contact path extending along a substantial length of the surface of each roller. Each special-purpose roller may be formed by positioning a cylindrical cutting tool, of a diameter equal to that of a tubular member to be roller straightened, at a selected acute angle to the axis of a roller blank and in contact with the roller blank, and then rotating both the cutting tool and the roller blank. Subsequent roller straightening will take place with each tubular member oriented at the selected acute angle to the finished roller. Alternatively, a mathematical analysis may be employed to characterize the required roller shape. Numerically controlled machining techniques may then be utilized to form the specialpurpose rollers in accordance with the determined shape.

    Abstract: A straightening machine for tubular or rod-like workpieces has concave straightening rolls which treat successive workpieces while such workpieces move lengthwise and rotate about their own axes. The feeding unit which advances workpieces into the range of the straightening rolls employs a pair of driven concave advancing rollers whose axes are inclined with reference to the axis of a workpiece between their concave surfaces. The advancing rollers can move successive workpieces at a higher speed so that the leading end of the workpiece between the advancing rollers catches up with the trailing end of the preceding workpiece which is being treated by the straightening rolls, and thereupon at a lower speed which corresponds to the speed of lengthwise transport of the workpiece at the straightening station. The speed of workpieces which are being transported by the advancing rollers can be varied by changing the inclination of the axes of rollers with reference to the axis of the advanced workpiece or by changing the operating speeds of series-connected hydraulic motors which rotate the advancing rollers.

    Abstract: An apparatus for laying a pipeline from a barge-mounted reel including compound-bending means, tensioning means and vertical support means. Each means preferably has an endless chain composed of blocks linked together by connecting pins. The pins also support high-load carrying rollers. The rollers ride both on relatively stiff tracks and on relatively flexible tracks which are supported by hydraulically-controlled rods operable to cause the flexible tracks to assume a desired curvature for imparting to the pipe. In the tensioning means, two such moving chains are oppositely positioned to directly engage opposite sides of a generally rectilinear portion of said pipe, thereby exerting a series of longitudinally-spaced, continuously-effective tensioning forces in the pipe. The apparatus further includes hydraulically-operated stanchions for selectively and adjustably supporting said pipeline in a vertical plane to allow the pipe to enter a body of water at a desired vertical inclination.
