ABSTRACT:
The printing products (33) to be pressed run through in an imbricated formation (S), in which the fold edges (33a) of the printing products (33) lie at the top, between the pressing rollers (3, 4, 5, 6) of two pairs of pressing rollers (1, 2) arranged one behind the other. The upper pressing rollers (3, 5) of each pair of pressing rollers (1, 2), which come directly into contact with the fold edges (33a), are fixedly mounted. On the other hand, the other pressing rollers (4, 6) of each pair of pressing rollers (1, 2) are mounted on each side in a common mounting (15), with the sides being resiliently mounted on pneumatic springs (16). The pressing rollers (3, 4, 5, 6) are driven individually by means of flexible drive belts (17, 18, 19, 20). By this arrangement, the printing products (33) can be pressed satisfactorily and gently even at high conveying speed.
