A method for cutting a ribbon of rubber-coated fabric includes dragging a free end of the ribbon past a working position of a punching device, forming a notch between two adjacent reinforcing cords of the ribbon using the punching device, moving a counter-blade of the punching device away from the working position, inserting at least one cutting blade through the notch, and performing first and second cuts of the ribbon. An associated apparatus includes a punching device and a cutting device. The punching device includes an incision tool, an abutting counter-blade, and control devices for moving the incision tool and the abutting counter-blade toward and away from the ribbon. The cutting device includes at least one cutting blade and a control device for moving the at least one cutting blade toward and away from the ribbon.
