The invention relates to a device for feeding, with elongate lining material, an installation for lining a tubular member such as a pipe having a diameter of the order of 650 to 1,000 mm, particularly in the nuclear industry. The pipe is placed with its axis horizontal on a support which enables it to be rotated about its axis. The lining installation comprises a vertical welding head which is mounted on the end of a horizontal arm, the position of which is adjustable to introduce the welding head into the pipe. The elongate lining material is supplied to the welding head by a feed device comprising a reel on which the lining material is wound, and which is arranged at the front of the welding head. The reel is mounted so as to rotate on an axle fixed relative to the end of the arm and whose axis forms a small angle with the axis of the arm. The device also comprises adjustable means for guiding the lining material from a low part of the reel to an upper part of the welding head. |
