Method and apparatus for manufacturing spiral-reinforcements for reinforced concrete
WO 2010044052 A3
Abstract
The method for manufacturing spiral reinforcements provides for feeding a metal wire (2) through a foldingunit (5) provided with a central mandrel (7) and an eccentric folding pin (8), having parallel axis, and for performing successive folds of said metal wire (2) with respect to the longitudinal feed axis (A), to produce a succession of polygonal coils (20) designed to form a spiral-reinforcement (21) constituted by a sequence of perpendicular tracts (22) and of oblique tracts (23) with respect to the longitudinal axis (L) of the spiral. On at least one side of the polygonal coils (20), to form said oblique tracts (23), are made a first fold (23a) on a plane orthogonal to the axis of the mandrel (7) and of the eccentric folding pin (8) and at least a second fold (23b) extended in a third dimension suitably inclined with respect to the aforesaid plane.
