<p>The subject of the present invention is a sliding tool to be fitted to boxes made from extendable steel known as "[rigoni] for walls". The invention is composed of a flexible angular structure to which are connected two parts designed to receive and lock a string called "Liniola". The tool permits the "Liniola" string to be stretched horizontally, correctly and rapidly, eliminating both problems due to a moving reference and interference with manufacturing defects in its production. The initial tension is maintained with time and it is possible, by making the tool slide along the vertical profile, to set the horizontal reference at various heights. Anchoring of the string is possible in several ways permitting the production of different types of product, both of type and shape. Optionally, a height reference can be provided for the execution of regular superimposed strokes of the parts. <IMAGE></p> |
