<p>The assembly is obtained from a continuous strip, the letters forming the separate panels, which are either parted along cut lines or joined along folds for stacking. Glued zones are provided on the front and/or back of the strip, to allow each panel to be held in position after folding. The fold lines form lengthwise or transverse strips, symmetrical in relation to the cut lines and divided into two or three sets of geometrical figures separated by safety margins which are as narrow as possible. The figures in one set are formed on a single panel by the application of self-adhesive glue so as to form a number of adhesive faces, symmetrical in relation to the fold lines on the panel.</p> |
