ABSTRACT:
An apparatus for the bending of large area construction units, particularly of tightly welded tube walls for boiler construction, with a supporting table for that part of the construction unit which is not to be deformed, which is held down at least in the vicinity of the bending zone by means of a moveable press. A pivot table is provided for bending the remaining part of the construction unit, which pivot table is equipped with a slide plate abutting the construction part to be bent. The slide plate is guided freely displaceable relative to the pivot table in the longitudinal direction of the same.
