Woven ribbon for sewing onto the upper part of shoes.

The innovation concerns a woven band with a width of 6-30 mm, which is sewn onto the underside of the shaft (2) of any type of shoe with waterproof, breathable films in order to prevent moisture from penetrating between the shaft lining (5) with applied water-repellent, breathable film (4), the shoe upper material (3) and the injected polyurethane sole (8).

The woven mesh tape (8) is made from monofilament or multifilament yarn made from polyamide 6 or 6.6, polyester, polyacrylic, polypropylene or polyethylene. It has a coarse-mesh and inflexible structure. On one side, it is placed lengthways around the edge of the shaft underside (2) and sewn to the shoe upper material (3). On the other side, the shoe inner lining (5) covered with the waterproof, breathable film (4) and the insole (7) are sewn on. When the polyurethane sole (9) is injected, the polyurethane material penetrates through the open, coarse-mesh structure of the woven mesh tape (8) and bonds firmly to the waterproof, breathable film (4). In this way, moisture that runs down the inside of the shoe upper material (3) cannot penetrate into the shoe through the insole (6).

Until now, the problem of sewing on this woven mesh tape (8) has been due to its inflexible application behavior in the area of the shaft curve at the tip of the shoe and in the heel area. Folds and creases form, which lead to leaks and deformations when the polyurethane sole (9) is injected, thus impairing the comfort of wearing the shoe.

The invention mentioned in the protection claim is based on the problem of creating a band that can be sewn to the extreme curvatures of the shaft corners without folds and creases.

This problem is solved with the feature of woven, controlled conicity listed in the protection claim.

The invention ensures that the conical woven mesh band (10) can take on the shape of the shaft curve at the tip of the shoe and in the heel area. The precise shape prevents the formation of folds and creases when sewing and applying the inflexible band in curves. The conical band therefore leads to more efficient processing in shoe production. The penetration of moisture is thus excluded, which also leads to an improvement in the quality of the finished shoe.

An exemplary embodiment is explained using Figures 1 to 3.

In Fig. 1, the complete shaft (1) without the injected polyurethane sole is shown in a view from below, so that the shaft underside (2) with the problem areas of the toe and heel can be seen

Fig. 2 shows the complete shaft (1) with the injected polyurethane sole (9). The woven mesh band (8) is sewn to the shoe upper material (3) on one side. On the other side, the woven mesh band (8) is sewn to the shaft lining (5) covered with the waterproof, breathable film (4) and to the insole (7).

In practice, the conventional woven mesh belt (8) is to be replaced by the conical woven mesh belt (10).

The conical woven mesh belt (10) is shown in Fig.3.
