Description

The present invention relates to a cut protection tarpaulin for tarpaulin arrangements, in particular of transport vehicles, and a method for producing such a cut protection tarpaulin. The cut protection tarpaulin comprises at least one first cut protection layer with a plurality of intersecting wire elements.

Trucks are often equipped with tarpaulin arrangements that cover their transport area and protect the cargo. However, the tarpaulins used in this case usually offer only very little protection against theft. For example, the tarpaulins are often cut open with a simple knife.

In the prior art, therefore, truck tarpaulins have become known, which are equipped with metal wires or metal fabrics. As a rule, the metal reinforcement is woven directly into the tarpaulin during production. Due to the more complex production such tarpaulins are often very expensive and usually only available as part of a new acquisition.

Solutions have become known in which existing truck tarpaulins are retrofitted with a correspondingly cut-safe additional tarpaulin. However, these additional tarpaulins also often have a very complicated and thus expensive tissue.

It is therefore the object of the present invention to provide an improved cut protection or theft protection for tarpaulin arrangements. The solution should in particular be cost-effectively manufacturable and economical to use and offer a particularly reliable protection.

This object is achieved by a cut protection tarpaulin with the features of claim 1 and a method for producing a cut protection tarpaulin with the features of claim 18.
