ABSTRACT:
An apparatus is provided for automatically bending tubular materials. The apparatus comprises a bending direction setter which is operative to securely grip a length of tubular material approximately centrally along the length of material. The bending direction setter is operative to rotate the tubular material about its original axis a preselected and carefully controlled amount. The bending apparatus further comprises a pair of automatic benders which are operative to engage the tubing at selected locations on opposed sides of the bending direction setter. The benders are operative to selectively engage the tubing material at a predetermined location therealong and to effect a controlled bend therein. The bending direction setter may rotate the tubular material about its original axis between successive bends carried out by the benders, thereby enabling the tubular material to be bent through three dimensions. The apparatus further comprises a takeout unit for removing the bent tubular product from the bend direction setter.
