Abstract
Abstract A permanent elastic net-shaped bandage including a fabric with elastic threads as warps and with non-elastic threads transverse thereto forming wefts. More specifically, the warps are designed as fringe warps of non-elastic threads and are independent of each other while being backed by an elastic synthetic thread. The non-elastic wefts always rest on the same spot of the fringe warp which is engaged by the adjacent weft and between the skips from fringe warp to fringe warp are in an arc-shaped manner lying a plurality of times on the fringe warp.
