    摘要： A pipe coupling 10 for straddling and securing together facing ends 16a,18a of a pair of pipes 16,18 of substantially cylindrical profile. The coupling has a plurality of segments 12,14 each having a pair of axially-spaced arcuate surfaces 32,34 adapted to interface with the outer surfaces of the pipes, and connection members 24,26 for adjustably drawing together the ends of the segments 12,14. Spacers 230 are positioned between the conjoined ends of the segments to maintain them in a sufficiently spaced apart relation to allow the pipe ends 16a,18a to be inserted therebetween. The spacers 230 collapse on subsequent tightening of the connection members 24,26, to permit the arcuate surfaces 32,34 to engage the outer surfaces 20,22 of the pipes 16,18 inserted between the segments 12,14.

    摘要： A roller set (10) for roll forming pipe elements has an outer roller (14) that engages the pipe element at two points to prevent teetering of the pipe element
    The roller set (10) comprises an inner roller (12) engageable with the inner surface and an outer roller (14) engageable with the outer surface. The outer roller (14) comprises an outer roller body (16) rotatable about a first axis (18). A first raised feature (20), engageable with the pipe element extends circumferentially about the outer roller body (16) and projects radially from the first axis (18). A second raised feature (22), engageable with the pipe element extends circumferentially about the outer roller body (16) and projects radially from the first axis (18), the second raised feature (22) being positioned adjacent to the first raised feature (20). Further, the inner roller (12) comprises an inner roller body (64) rotatable about a second axis (66). A first depression (70) extends circumferentially around the inner roller body (64). A second depression (72) extends circumferentially around the inner roller body (64) and is positioned adjacent to the first depression (70). A projection (84) extends circumferentially around the inner roller body (64) and projects radially from the second axis (66), the projection (84) being positioned between the first and second depressions (70,72) and having a radius greater than the radius of a portion of the inner roller (12) proximate to the second depression (72). The inner and outer rollers (12,14) cooperate to form the region of the pipe element whereby the first and second raised features (20,22) align respectively with the first and second depressions (70,72).

    摘要： A device and a method thereof for forming the ends of a pipe element. The device (74) comprises a first roller (78) and second roller (80) for imparting a shape to a sidewall of a pipe element. The first roller (78) rotates about an axis (82) and comprises a first segment (94) having a first outer diameter (94a); a second segment (96) positioned contiguous with said first segment (94) and having a second outer diameter (96a) smaller than said first outer diameter (94a); a third segment (98) positioned contiguous with said second segment (96) and having a third outer diameter (98a) larger than said second outer diameter (96a).
    The second roller (80) rotates about an axis (88) and comprises a fourth segment (104) having a fourth outer diameter (104a); a fifth segment (106) positioned contiguous with said fourth segment (104) and having a fifth outer diameter (106a) greater than said fourth outer diameter (104a); a sixth segment (108) positioned contiguous with said fifth segment (106) and having an sixth outer diameter (108a) less than said fifth outer diameter (106a); and a seventh segment (110) positioned contiguous with said sixth segment (108) and having a seventh outer diameter (110a) approximately equal to said fifth outer diameter (106a).
