ABSTRACT:
A universal plying iron is described, consisting of a base plate with a mold support positioned on bracket supports in such a way as to match the contour and mold level of the section to be bent on the base plate, the section to be bent, in the form of a bending template, being bent by means of mold rollers around a section support projecting from the mold support. For the universal application of the plying iron, without the need for involved modification of the bending molds, the bracket supports are positioned in adjustable fashion on the base plate and tension elements are provided on the bracket supports, which tension elements stress the mold support and simultaneously carry the section support, and can be adjusted to the desired height.
