| 摘要 |
The present invention includes a rotatable nozzle arrangement (1) comprising a nozzle (7) and a bearing unit (19) (or a motor unit), whose rotatable axel (19a) is co-ordinated with the nozzle, wherein the nozzle (7) is adapted to sling or distribute out a curable viscous plastic material (E2, E2') when it rotates within a tubular section (22), this material being collected, inter alia, in a magazine (16) in the nozzle (7) and being slung against the inner surface (24) of the tubular section (22) and there create and build-up a viscous coating (10) of given thickness. The plastic material (E1) is fed to the nozzle (7) and its magazine (16) and is concentrated to an inner wall-portion (7c) of the nozzle (7) in the form of a straight truncated cone. The rotational axel of the bearing unit (18') and the rotational axel (7') of the nozzle (7) are eccentrically orientated. |
