Wooden roofing folder with a piece of tin inserted ready to fold
The folder is shown in [Fig. 53]. Both of these views are sectional to show the working of the folder. The actual construction may be easily understood by looking at the actual folder. The gauge B, [Fig. 52], is adjusted by first loosening up the five screws E with a screw driver and then pulling in or pushing out the gauge B to the desired width of the fold to be made. The screws E are then tightened up with the screw driver and the tin inserted between the pieces A A. The folder is then closed by grasping the handle D and closing the two sides of the folder together. When the folder is opened, the tin will be found to be folded over.
