  • Patent number: 4343615
    Abstract: Stacks of individual relatively small rectangular sheets bearing printed characters are formed by first printing the characters in a grid on a substantially larger sheet, then stacking those sheets in registration, wrapping it with a transparent adhesive material, cutting it into strips along the grid line, coating the surfaces exposed in the cut with adhesive material and reconstituting the strips into a tablet or pad. Then cutting the tablet or pad laterally and removing the last layer of adhesive material applied before arranging the stacks into an index selector board for use in composing strips of type.
