Abstract (en)

A description is given of a device for winding on a single axis (A) a plurality of rolls (R) of pre-cut bags fed in parallel strips or tracks (S), comprising, for each strip of bags (S), a contrast roller (51), normally idle and resting on the relative roll (R), means (40) suitable for detecting the tension of said strip of bags (S) and means (M), controlled by the detecting means (40) when a slackening in the strip of bags (S) is detected, for making said roller (51) rotate at a peripheral speed greater than that of the strip of bags (S), making said roll (R) rotate at an angular speed greater than that of the other rolls on the same axis (A).
