<p>Method for tailoring of the cloth edges of rollable decoration screens such as indoor and outdoor sunscreens. The cloth edges on top and bottom will be subsequently folded back inwardly and then are interconnected to the single base cloth, which side edges are reinforced over their entire length. This is effected by integrating and interconnecting a relatively narrow band or a strip by means of heat welding connected to the cloth edge whereby the total thickness of the edge obtained by such method is equal to or does not exceed the thickness of the single base cloth. The improvement also relates to the apparatus applied for the heat welding as well as to the cloth resulting from said method.</p> |
