A method and an apparatus are for forming open-edge V-shaped notches (32) in a binding margin (42) of large-format sheets (11) such as shop drawings or construction plans for example, so that after the sheets have been folded the notches (32) are aligned in registration with binding holes (46) also provided in the binding margin. A cutting and crosswise folding table (20) is provided at the top of a folding machine, and stamping tools (22) are provided at an edge of the table. The large-format sheets are continuously, sequentially output from a device such as a plotter, and fed to the folding machine, where the sheets are folded lengthwise and transported onto the table (20). There, the notches are cut in the binding margin by the stamping tools. The binding holes may be simultaneously formed. Thereafter, a crosswise folding beam (65) folds the sheet in a crosswise direction. The sheets that have been provided with notches and holes, and have been folded in this manner, may be bound in a ring binder in such a manner that the sheet can be completely unfolded without being removed from the binder.
