Method of and apparatus for the winding up of webs, especially synthetic resin foil webs
 Instead of long stroke piston and cylinder arrangements for actuating the counterroller of a foil-winding system, a rotary field servomotor can form a drive unit for the counterroller and can be angularly displaceable with the angular displacement being controlled by a pneumatic piston which exerts the pressure required between the contact roller and the roll.
