Abstract
The grid is provided with resilient and rigid bearing elements. The former consist of corrugated resilient bands which are suspended via lateral faces (b, c) provided on their ends in recesses (5, 6) of the mesh walls (1, 2). By suspending one such spring each from both sides of the mesh wall in the same recesses, their mutual retention or mounting is achieved.
