<p>The label mounting is for a wire-type folder for loose sheets, and is trough-shaped with a flat base and a holder for the label on the outside. At one end in each of the flanges it has a notch, extending in the lengthwise direction (6a,6b), and whose shape and dimensions are such that it can be snapped by force over a taut binder wire (7) and released by a sharp tug. The trough flanges can be of elastic semi-flexible material, each notch width being slightly greater than the wire diamter. Its centre line is at a distance from the trough base equal to that of a binder wire from the paper edge. The side of the notch furthest from the base has a protrusion towards the interir, with a ramp face at the free end and an arc-shaped one at the other, so as to form a circular support for the wire.</p> |
