Abstract
A tube mat made of elastomer material in the form of an extrudate includes first and second front faces which are arranged in a vertical or angled manner in relation to the extrusion direction. A plurality of tubes extend in parallel in the extrusion direction between the two front faces. At least a portion of each tube is closed at adjustable distances whereby a closed air column respectively is formed and whereby the tube seal together with the tube mat forms a one-piece elastomer composite. A method for producing the tube mat is also provided in which after the extrusion, the tubes are closed at certain points by means of pressure and a pad roller, whereby beads and closing webs are produced. The pad roller is provided with pins that are distributed over the circumference of the roller. Vulcanization is carried out subsequently.
