ABSTRACT:
A method and apparatus for bending tubular bodies, wherein elemental tubular sections are gradually shifted with respect to each other, without rotation, in a V-shaped bend from a central bend section. The apparatus includes two slidingly fitted supports for housing the tubular body to be bent, and a central triangular presser acting between the supports on the central tube section. The supports are gradually moved by the presser in opposite directions to define the tube sections that are actually shifted.
