FIELD: mechanical engineering, in particular, scan application of information with variable width of dash contour. ^ SUBSTANCE: method involves supplying voltage to working members of scanning tool from current source, with selected voltage value being proportional to ratio of desired width of dash on blank to width of dash on scanning tool. Apparatus has scanning grate consisting of isolated current-conductive operating and inoperative members connected to programming device. Apparatus is further equipped with dash contour width sensor connected to analog system for identifying members of signs in scanned area. Outer operating and inoperative members of scanned area are arranged in offset relation, with offset value approaching half the difference between maximum and minimum width of contour of opposite dash of information applied, and section of operating and inoperative members of scanned area being not in the excess of minimum width of dash contour on blank. ^ EFFECT: wider operational capabilities and provision for obtaining of types with variable width of dash contour. ^ 3 cl, 2 dwg |
