Rollers, also called slip rollers, are tools that use adjustable hardened-steel rollers to make an even cylindrical bend in sheet, plate, tube, or solid stock. Rollers can be either manual or electric powered and come in a variety of widths so as to be able to roll Richard Serra–sized work all the way down to compact jewelry work. Rollers consist of one or two drive rollers that force the material through an adjustable gap in a trailing roller to give it its bend, as seen in Figure 8.1. The closer the adjustable roller is to the guide rollers, the tighter is the bend. Thicker-walled tubing may be able to be rolled on a regular slip roller, but thinner-walled tubing usually will be crushed without the extra side support ...
