Tool (10) has a shaping or cutting element (12) with raised cutting ribs (32, 34) following the outer and inner edges of a symbol, and transverse ribs (52, 54) that connect the outer and inner ribs to form gaps that produce tongues of the plate or sheet material used for the symbols. Tool (10) has a shaping or cutting element (12) with raised cutting ribs (32, 34) following the outer and inner edges of a symbol, and transverse ribs (52, 54) that connect the outer and inner ribs to form gaps that produce tongues of the plate or sheet material used for the symbols. The tongues are connected to the inner and outer portions of waste material so that they are all removed together. The transverse ribs are in parallel pairs that lie at an acute angle, preferably between 45 and 70 degrees, to the main cutting ribs, and the distance between them is preferably between 0.05 and 0.25 of the space between the main ribs. The cutting element (12) of the tool, made from steel, fits into a plastic sole plate (14) that is attached to a support (24) carrying all the symbols required for a licence plate. |
