The template groove 5 of the ruler according to the invention is delimited, on the one hand, by an edge 6 at right angles to the bottom of the groove and, on the other hand, by an undercut and bevelled edge 4, adjoining which there is a narrow channel 3 which extends along the bottom of the groove and of which the upper corner at one edge forms a pivot for templates 2 placed in the groove. These templates can thus be tilted up out of the groove, for example for replacement. This design of the template ruler eliminates the need for limit stops 7 fixing the templates and for breaks, since, according to the invention, members are provided for adjustable and/or resilient charging of one edge of the templates against the bevelled edge of the template ruler. <IMAGE> |
