    摘要: According to the present invention, there is provided a method and an apparatus for ejecting a helically wound pipe section from a mandrel (5), wherein the mandrel (5) has a longitudinal axis around which it is rotated and a cylindrical outer surface around which the profile forming the pipe section is wound. The method comprises steps of cutting the profile that is wound on the mandrel (5) to form an end of the pipe section, pushing at least one ejector element against the end of the pipe section, holding the at least one ejector element stationary in the direction of the longitudinal axis of the mandrel (5) and rotating the mandrel (5) and pipe section in the same direction as the profile is wound on the mandrel.

    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.
