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.
Les articles imprimés (33) à presser traversent une formation en écailles (S), dans laquelle les bords repliés (33a) des articles imprimés (33) reposent à l'extrémité supérieure, entre les rouleaux (3, 4, 5, 6) de deux paires de rouleaux de pressage (1, 2) situées l'une derrière l'autre. Les rouleaux supérieurs (3, 5) de chaque paire de rouleaux de pressage (1, 2), qui entrent directement en contact avec les bords repliés (33a), sont montés de manière permanente. Les autres rouleaux (4, 6) de chaque paire de rouleaux de pressage (1, 2) sont montés de chaque côté dans un cadre commun (15) dont les côtés sont montés de manière élastique sur des ressorts pneumatiques (16). Les rouleaux (3, 4, 5, 6) sont entraînés individuellement par des courroies d'entraînement flexibles (17,18, 19, 20). Les articles imprimés (33) peuvent ainsi être pressés de façon satisfaisante et en douceur, même à une vitesse de transport élevée.
