Abstract

Das Spiralgliederband besteht aus einer Vielzahl von Kunststoffspiralen (1), wobei die Windungen einer Spirale reissverschlussartig mit den Windungen der benachbarten Spiralen ineinandergreifen. Steckdrähte (2) sind in die Ka­ näle eingeschoben, die durch die ineinandergreifenden Windungen jeweils zweier Spiralen gebildet werden, wobei die Windungen der Spiralen in das Material der Steckdrähte eindringen und die Spiralen ovale Form mit in Längsrich­ tung der Spiralen verbreiterten Köpfen (3) an den Win­ dungsbögen haben. Die Breite der Köpfe (3) der Windungs­ bögen (7) ist etwa das 1,5- bis 2-fache des Durchmessers der Drähte, aus dem die Spiralen (1) gewickelt sind. Die Spiraldrähte können auch einen nieren-, U- oder V-förmi­ gen Querschnitt mit einer konkaven und einer konvexen Seite aufweisen und so gewickelt sein, dass die konkave Seite (6) nach innen oder aussen zeigt. Die Spiralen (1) sind dabei im Bereich der Windungsbögen (7) flachgedrückt. Das Flachdrücken erfolgt während des Thermofixierens. The spiral link belt consists of a variety of Plastic spirals (1), the turns of a spiral zipper-like with the turns of the neighboring ones Intertwine spirals. Plug wires (2) are in the Ka channels inserted through the interlocking Turns of two spirals are formed, whereby the turns of the spirals in the material of the plug wires penetrate and the spirals oval shape with in longitudinal direction device of the spirally widened heads (3) on the win have questionnaires. The width of the heads (3) of the winding bends (7) is about 1.5 to 2 times the diameter the wires from which the spirals (1) are wound. The Spiral wires can also be kidney, U or V-shaped cross section with a concave and a convex Have side and be wound so that the concave Side (6) points inwards or outwards. The spirals (1) are flattened in the area of the winding arches (7). The flattening takes place during the heat setting.
