    • For the production of loop handle shopping bags based on semi-tube sheeting consisting of thermoplastic plastic, an edge strip of the semi-tube sheeting is folded onto itself and reinforcement warps, consisting of a weld-friendly thermoplastic plastic that provides a good weld, are attached on the interior sides of the edge areas by means of glueing or welding at a distance corresponding to the width of the shopping bags to be produced.Subsequently, the edge strip is folded back so that the added reinforcement warps are positioned back-to-back. Double-layer handle strips are positioned in a U-shape and placed between the reinforcement warps with their end areas of the free shanks, and welded together with the edge areas through the reinforcement warps between welding devices. The shopping bags are then separated from the semi-tube sheeting by means of separating weld seams.
    • 为了生产基于由热塑性塑料组成的半管片的环形手柄购物袋,半管片的边缘条折叠到其自身上并加强经线,由可焊接的热塑性塑料组成,提供良好的焊接, 通过胶合或焊接在与要生产的购物袋的宽度相对应的距离处附接在边缘区域的内侧。 随后,边缘条被折回,使得附加的加强件扭曲被背对背地定位。 双层手柄条定位为U形,并放置在加固经纱与其自由柄的端部区域之间,并通过焊接装置之间的加固经线与边缘区域焊接在一起。 然后通过分离焊缝将购物袋与半管板分离。
