发明名称 Method and apparatus for the cold shaping of metal rods by bending
摘要 In a method for the cold shaping of metal rods by bending, in particular for bannisters, grilles for windows, doors, fences or the like, a plurality of successive bends alternately facing in opposite directions and lying in one plane are formed one after the other. In order to reduce the complexity of production and preclude the misalignment of the bends, the bends are formed continuously by a rolling operation. <IMAGE>
