  • Patent number: 5471856
    Abstract: A bending processing apparatus includes upper and lower molds made of a flexible synthetic resin material which are interposed between end surfaces of a plurality of driven cylinders opposing a corresponding plurality of movable cylinders. This arrangement is mounted on a base stand and an article to be subjected to bending processing is supported by pressure between the upper and lower molds. A control unit is provided for controlling a stroke amount, stroke order and speed of the respective cylinders such that pressing force may be uniformly obtained during bending processing, thus wrinkling or finding in the article during processing is prevented.
