Plastic Mesh Having Double Chains, and Device for Producing a Plastic Mesh

A plastic mesh, comprising a plurality of chains extending parallel to one another in a longitudinal direction, wherein:

• at least two chains extend at a short distance to one another and form a group of chains;
• at least one additional chain is adjacent to the group of chains;
• the distance between the at least one additional chain and the group of chains is greater than the short distance between the chains within the group of chains;
• a thread runs back and forth between the additional chain and the group of chains and connects the additional chain and the group of chains;
• a plurality of additional groups of chains is adjacent to one another and each formed of at least two chains,
• the plurality of additional groups of chains has a greater distance between one another than the at least two chains within the group of chains;
• a thread runs back and forth between two adjacent ones of the additional groups of chains in each case and connects the additional groups of chains;
• the plastic mesh is completely formed by groups of chains.
