Abstract
An installation for deforming a strip in order to form a hollow body, preferably a tube, consisting of a forming tool to which, at an angle with respect to the main axis of the forming tool, the band is fed by means of rollers, one of which , at least, is a driven roller, and by means of a guide member that prevents bending of the band, and the manufactured hollow body is supported by a support disposed behind the forming tool, the angle between a longitudinal edge being adjustable. of the band and the main axis of the forming tool and welding the band fed with the already curved band in the area of the forming tool, characterized in that a semi-open tool is used as the forming tool and the band is introduced at an angle alpha 'in the useful former that is smaller than the alpha angle that must be adjusted for the production of a hollow body whose outer diameter corresponds to the diameter of an imaginary roller, tangent to the points of contact of the forming tool, and in that the forming tool can be tilted with respect to the members driving the strip 1, during operation and the support supporting the finished hollow body, which bears a bezel, can be tilted with the useful trainer and also with respect to him.
