Abstract

A pipe-forming machine for forming helical pipes by winding strips (40) into a helical shape, comprises a plurality of following rollers (21a) which are rotatable and arranged at a fixed helical angle on the circular area of a virtual cylinder at least one of first and second pairs of driving rollers (16a, 21b) which hold and convey the strips therebetween in such a manner that the following rollers rotate while being kept in contact with the inner surfaces of the strips and a pair of tension rollers (18b, 18c) which hold the strips therebetween so that the strips can be conveyed to the following rollers and which cooperate with the driving rollers to keep the strips in tension in such a manner that the following rollers rotate while being kept in contact with the inner surfaces of the strips.
