PCT No. PCT/DE97/01192 Sec. 371 Date Feb. 13, 1998 Sec. 102(e) Date Feb. 13, 1998 PCT Filed Jun. 12, 1997 PCT Pub. No. WO97/47934 PCT Pub. Date Dec. 18, 1997The position of a printed web passing through an elongated dryer is shifted laterally during passage of the web through the dryer. A component of the resultant of all of the frictional forces acting on the web is caused to point in the lateral direction of the desired web shaft. This resultant of the frictional forces is obtainable by changing the spacing of blower nozzles, or by changing the pressure of discharged drying fluid across the width of the web.
