What is a used pyramid, plate or bending rolls?
A roll bender is a mechanical jig having three rollers used to form a metal bar into a circular arc. The rollers freely rotate about three parallel axes, which are arranged with uniform horizontal spacing. The two outer rollers have the same fixed vertical height and make contact with the underside of the bar to be formed. The middle roller has an adjustable height and makes contact with the topside of the bar.
The bar to be shaped is assumed to have a uniform cross-section, but not necessarily rectangular, as long as there are no overhanging contours, i.e. positive draft. Such bars are often formed by extrusion. The bar is suspended between the rollers. The end rollers support the bottomside of the bar and have a matching contour (inverse shape) to it. so to maintain the cross-sectional shape. Likewise, the middle roller is forced against the topside of the bar and has a matching contour to it.
