Abstract

It consists of a device formed by a rectangular rigid frame A to whose ends are secured two reels B and C and over which run two rails D which contain a box with a movable block of chalks or other pigment E. The box is displaced longitudinally along the rails and downwards above the hollow of the frame. The text to be printed is stamped on a strip of flexible plastic material F in one of the two "bobonas" and joined to the other passing behind the frame. When the box is lowered, the pigment enters into contact with the flexible strip located immediately below. In order to print the text, the box is pressed on the strip, displacing it from right to left. Applicable basically to the area of teaching.
