[origin: DE4431648C1] The single (13) or several (14) gas-filled cells are positioned between the feed roll suspension tube (2) and the elastic, hollow-cylindrical pressure surface (9) extending coaxial with the suspension tube. The radially outer surfaces of the cells form part of the elastic pressure surface. The closed and interconnected cells are arranged over the length of the suspension tube and are positioned on flexible support material lying in several layers on the suspension tube.
