A pressure pad comprises a plenum chamber, adapted to be conneceted to a pressurized-fluid supply means, having a pair of parallel slit nozzles formed in a top wall, and the chamber is arranged underneath a path of a strip. The plenum chamber is provided with holes in the top wall and at least two obstructing means on the top wall. The holes are arranged on imaginary lines that extend between the nozzles on both sides of the top wall and central portions thereof point to adjacent edges of the path. Each of the obstructing means comprises at least one obstructing wall arranged on either side of one of the imaginary lines. The lines may have V-, Arch- or Bracket-shaped configurations. <IMAGE>
