Method and apparatus for applying a rotationally driven pressure roller ( 4 ) onto a rotationally driven goods guiding roller ( 3 ), especially in a stretching equipment for thermoplastic films, whereby the pressure roller ( 4 ) is advanced in the direction of the goods guiding roller ( 3 ) by at least one first pressurizable piston-cylinder unit ( 7 ) in such a manner so that after the advancement an axis-parallel remaining stroke exists between the pressure roller ( 4 ) and the goods guiding roller ( 3 ), whereby thereupon at least one second pressurizable piston-cylinder unit ( 8 ) operatively connected with the first piston-cylinder unit ( 7 ) carries out the remaining stroke, while maintaining the axis-parallelism, until a touching contact exists between the pressure roller ( 4 ) and the goods guiding roller ( 3 ), and whereby thereupon the pressure roller ( 4 ) becomes effective with a nominal pressing force onto the goods guiding roller ( 3 ).
