ABSTRACT:
A method and apparatus for automatic line width adjustment for engraving characters on a piece of sign material utilizes two cutters sliding by each other in face-to-face opposing relationship. Line width is controlled by controlling the spacing between a pair of cutter tips. The two cutters are moved over a portion of a sign blank while being rotated with the selected spacing between the cutter tips to effect a selected cutting width. The cutters are held in holders and are replaceable when worn out. An internal ratchet-and-pawl mechanism provides fifteen different cutter line widths. The cutter head is moved into engagement with an external pawl mechanism to operate the internal ratchet-and-pawl mechanism.
