    摘要： Device and connector tube for coating a pipe (1) or portion of a pipe, which has an outer surface determined by the outer circumference of the pipe (1) or portion of a pipe. The device comprises a moving device (5), which can rotate around the outer surface of the pipe (1) or portion of a pipe, and a coating nozzle (8), which is connected to a molten- polymer source (15) in order to form a polymer film, which nozzle (8) is attached to the device (5), which can rotate around the pipe. The feed tube (19, 20) forms at least part of the molten polymer's feed route from the source (15) to the coating nozzle, which feed tube comprises at least two rigid tubes (19) and at least one connector (20), which com¬ prises at least two connector parts (21; 24, 27) for connection to the tube (19) and a bearing arrangement (23) fitted between the connector parts, which permits the connector parts (21; 24, 27) to rotate around their common longitudinal axis and keeps the connector parts (21; 24, 27) parallel to each other.

    摘要： A method and apparatus in the manufacture of a spirally wound and welded tube is disclosed. A thermoplastic profile is slid along a path on a slider arranged in an axial direction of the tube and defining a cylindrically shaped winding surface with a diameter corresponding to the inner diameter of the tube to be manufactured. The profile is directed along a spiral path towards a previous turn of said profile by means of radial rollers spaced along said spiral path by adjusting the position of the rollers: Opposite edges of said profile turns are welded together by providing an extruded welding mass between said profile turns. The welded tube is fed from the welding station by means the rollers by sliding it onto a rotating support.
