ことを特徴とする造管用成形ロール装置。[Claims for Utility Model Registration] A thin metal tape is curved and deformed by sequentially passing through a plurality of pairs of upper and lower rolls and a plurality of pairs of left and right rolls, and the abutting portions are welded, and a wire such as an optical fiber is inserted inside the tape. In a forming roll device for forming pipes that forms a pipe with a substantially circular cross section through which a strip is inserted, a displacement sensor for detecting the relative position of a pair of rolls is provided on each pair of upper and lower rolls and/or each pair of left and right rolls. In addition, a digital display section for displaying the detected value of the displacement sensor is provided near the operating section for moving the roll axis, and the operating section is configured to be operated in accordance with the detected value of the digital display section. A forming roll device for pipe making characterized by:
