which will come down and hold the material firmly during the bend. This clamping action may be manual, automatic or operated using a foot pedal. The front, gate-like, plate of the machine is hinged and may be lifted, forcing the material extended over a straight edge to bend to follow the plate.

A bar folder is a simplified brake, usually much smaller than a cornice or box-and-pan brake. Typically, a single handle both clamps the workpiece and makes the bend, in a single motion. There is a gauge that can be set up to a depth up to one inch for consistent bends.
217:
In a box-and-pan brake (also known as a finger brake), the clamping bar includes several removable blocks, which may be removed and rearranged to permit bending of restricted areas of a piece of sheet metal or of already partially formed pieces.
209:, somewhat more in the case of a bar folder. If the area to be bent is narrow enough, a sharper bend (e.g., for a hem) can be made by inserting the bend under the clamping bar and lowering it.
