<p>This Architectural Drawing is AutoCAD 2d drawing of Details of Bending roll in AutoCAD, dwg file. Roll bending is comparable with bending, because the material is formed by the force applied. <strong>The process is used when a sheet metal panel has to be bent to a larger, smooth, radius</strong>. Radii can also be produced by bending with bump-bending. In this case, the plate metal is bent in small steps to the desired radius.</p>
