Abstract
A method and apparatus for bending an elongated piece, wherein the piece is fed to and held by feeding rolls and bending rolls which are spaced from each other, the piece is bent by displacing the bending rolls in directions perpendicular to the longitudinal axis of the piece and is twisted by rotating the bending rolls about the longitudinal axis of the piece.
Claims5
An apparatus for bending an elongated piece which is conveyed in the longitudinal direction thereof, comprising a feeding unit having a pair of feeding rolls for feeding an elongated piece having a longitudinal axis along a path into a bending unit having a pair of bending rolls located downstream from said feeding unit, said feeding rolls and said bending rolls being arranged along said path and separated by a predetermined distance, said bending unit comprising means for displacing the bending rolls in directions perpendicular to the path to bend the elongated piece in the directions perpendicular to the longitudinal axis of the elongated piece and for rotating the bending rolls about the axis of the path extending through the nip of the bending rolls and the longitudinal axis of the elongated piece to simultaneously twist and bend the elongated piece said bending rolls serving to movably support said elongated piece so that said piece can be fed through said bending rolls for said bending and twisting operations and means to simultaneously rotate and perpendicularly move said bending rolls.
