Turning over the edge of a sheet metal disc

A sheet metal disc 20 is rotatably supported at its centre, and is supported separately near its edge by supports 23, 24. The edge portion of the disc 20 beyond the supports extends initially between two tapered rollers 29, 30. The rollers move in the axial direction of the disc 20 while the disc ro...

Zusammenfassung:	A sheet metal disc 20 is rotatably supported at its centre, and is supported separately near its edge by supports 23, 24. The edge portion of the disc 20 beyond the supports extends initially between two tapered rollers 29, 30. The rollers move in the axial direction of the disc 20 while the disc rotates about its axis, so that the edge portion is turned and comes to lie between one of the rollers 30 and the separate support 23. If the rollers and the separate supports are radially (of the disc) movable with respect to the centre support 21, 22, the apparatus can provide a range of diameters for the disc 20 after turning over.
