摘要： PURPOSE:To obtain a titled machine that performs prescribed bending work by bringing a follower roll consisting of many coaxial disks that can rotate independently close to a replaceable tapered driving roll and holding a work to press-contact between them in forming bending work of a conical cylindrical body. CONSTITUTION:A tapered driving roll 1 is placed at the tip 6 of a sliding stand 5. Tilting of a follower roll 2 having outer periphery consisting of many disks 19 made of urethane etc. that can rotate independently and coaxially is made to conform to the taper of the driving roll 1. A rotary actuator 9 is operated to press-contact the rolls 1, 19. A material to be worked is passed between them by the rotation of the driving roll 1 and bending work is performed by deformation resistance of the urethane disk 19. As the disk 19 rotates freely and independently, no excessive force is applied in bending, and accurate bending work can be effected.

摘要： PURPOSE:To reduce cost and labor and to obtain a formed article having a desired diam., by passing a workpiece between two rolls to form it into a circular-arcuate shape, and press-bending the extending the passing workpiece by a press member provided to the outlet side. CONSTITUTION:A pressing roll 22 is vertically moved by operation a hydraulic cylinder to press the roll 22 against a pressed roll 24. When the roll 22 is rotated while pushing the end of a workpiece against the contact point between both rolls 22, 24, the workpiece is drawn in-between both rolls and is discharged from the opposite side of both rolls, while being bent into a circular-arcuate shape with the roll 24 inside. Here, the workpiece is finished into a formed article, while being pressbent and extended in the reverse direction by a press member 26, located between the roll 24 and the workpiece, to wrap the workpiece around the roll 24.
摘要翻译：目的：为了降低成本和劳动力并获得具有期望的直径的成型制品，通过使工件在两个辊之间通过以将其形成为圆弧形状，并且通过提供的冲压构件将弯曲延伸通过的工件到出口侧。构成：通过操作液压缸使压辊22垂直移动，以将辊22压靠在压辊24上。当辊22在将工件的端部压靠在两个辊22,24之间的接触点的同时旋转时，工件被拉伸在两个辊之间，并且从两个辊的相对侧排出，同时将辊24内弯曲成圆弧形。这里，工件被成形为成型制品，同时被压靠并通过位于辊24和工件之间的压力构件26沿相反方向延伸以将工件包围在辊24周围。

摘要： PURPOSE:To constitute a bending roll machine which is easily operatable by extending freely tension-adjustably and cyclically movable forward and backward a belt to plural pieces of rolls and providing an inside bending roll which is freely attachable and detachable to and from the belt to the intermediate of the two rolls. CONSTITUTION:The plural rolls 17, 19, 21 are freely rotatably provided in parallel and the freely tension-adjustable belt 23 with the roll 21 as a tension roll is put thereon. The working roll 25 which is freely attachable and detachable to and from the belt 23 is provided to the intermediate of the two rolls 17, 19 which are invariable in the rotating position. The top end of a piston rod 29 energized downward by a spring 27 is attached to the roll 21. The belt 23 is turned in this state and the bottom surface of a sheet material W is supported over the entire part by the belt 23, thus the material W is formed by the roll 25. The material W is thus easily bent to the desired inside curvature.
摘要翻译：目的：构成一种弯辊机，其可通过自由张力可调并且周期性地将皮带向前和向后移动到多个卷筒上并且提供内侧弯曲辊，其可自由地附接和从皮带分离到中间的两卷。构成：多个辊17,19,21可平行地可自由转动地设置，将作为张力辊的辊21的自由张力调节带23放在其上。可向皮带23自由地安装和拆卸的工作辊25设置在旋转位置上不变的两个辊17,19的中间。由弹簧27向下通过的活塞杆29的顶端安装在辊21上。带23在该状态下转动，片材W的底面通过带23支撑在整个部分上，因此材料W由辊25形成。因此，材料W容易弯曲到期望的内部曲率。
