The inventive method and the inventive device are designed for unwinding from a roll (1) the scaled formation of printed products wound onto a winding core (11) with the help of a winding tape (12). The braking of the rotation of the roll (1) necessary for maintaining the tension on the winding tape during unwinding, is produced by pressing one face of the roll (1) against an inclined supporting surface (1) by means of a component (N) of the roll weight, such causing friction between the face of the roll and the supporting surface (10) which friction brakes the rotation of the roll.
Méthode et dispositif conçus pour dérouler à partir d'un rouleau (1) des produits imprimés disposés en cascade enroulés sur un mandrin (11) à l'aide d'un ruban d'enroulement (12). Le freinage de la rotation du rouleau (1) nécessaire au maintien de la tension sur le ruban d'enroulement pendant le déroulement est obtenu en comprimant une face du rouleau (1) contre une surface d'appui inclinée (1) au moyen d'une composante (N) du poids du rouleau, ce qui provoque de la friction entre la face du rouleau et la surface d'appui (10) qui freine par friction la rotation du rouleau.
