<p>A system for low-force roll folding effects bending of a two-dimensional sheet material having one or more predetermined fold lines into three-dimensional article. The system may include a sheet material with bend-facilitating structure extending along a length one or more of the predetermined fold lines, a stand of rollers configured to effect bending of the sheet metal along the bend-facilitating structure, and a driver to move the stand of folding rollers relative to the sheet material along the length of one or more of the predetermined fold lines to effect bending of the sheet material along the bend-facilitating structure. A method for low-force roll folding is also disclosed.</p> |
