摘要：
A method for turning or laterally shifting a web in a printing machine includes guiding the web successively around four rollers. Roller 2 is rotated with respect to roller 1 by about 90°, so that a strand of the web extending between the first and second rollers performs a first twist by about 90°. Rollers 1 and 3 are substantially parallel so that the strand of the web extending between the second and third rollers is straight. Roller 4 is rotated with respect to roller 3 by about 90°, so that a strand of the web extending between rollers 3 and 4 performs a second twist by about 90°.
