Abstract (en)
[origin: WO9937576A2] A rolling installation for making creases in a web of material, such as cardboard, comprising a pair of rotary rollers (1, 2), each of which is mounted at its two ends in bearings and each of which is provided with roll surfaces by means of which the rollers are rollable with respect to one another leaving a gap (7) between the roll surfaces, one of which rollers is provided with at least one ridge and the other of which is provided with at least one groove, and the rollers are synchronised such that at the location of the gap each ridge is opposite a groove. Multiple parallel ridges (11) are provided on the one roller and corresponding multiple parallel grooves (13) are provided on the other roller in order to form multiple parallel creases in the web of material, at the location of which creases a rounded corner can be formed.
