Abstract
A process of making an adjustable diameter barrel form includes the steps of providing a sheet formed of metal and folding the sheet along a widthwise bend. Pressure is applied to the sheet along the bend within a rolling device. The sheet is rolled within the rolling device over its length gradually moving the bend from one lengthwise end to the other lengthwise end while applying the pressure. The pressure is removed to release the sheet so that the sheet can roll up in a lengthwise direction into a coil. The rolling device can include a pair of rollers, an arbor, and a mandrel on the arbor. The rolling device can include a base plate, a press plate, and a mandrel between the plates.
