摘要：
The present invention provides a bending machine for strip, webbing, or rod material comprising: an electronic control means; two cylinders, each acting selectively as a forming mandrel or a forming tool; an angular displacement means, controlling the orbit of the forming mandrel; and a feeding means, controlling the rate of material advancement; wherein a curvilinear profile of varying radii is formed in at least a portion of a material by varying the feed rate and the angular displacement, individually or in conjunction.
