Abstract (en)
A device for feeding/drawing a web material such as webs of paper or the like, comprises at least two parallel contrarotating rollers (1, 2) between which the web (3) is passed. One of the two rollers (1) is provided with at least one, preferably two or more peripheral impression punches (106) axially adjacent to one another and capable of being substituted and/or combined with each other, while the other roller (2) has an opposing surface (202). One of the rollers (1) carries, at an intermediate point, at least two circular or part-circular coaxial rings (6, 6', 6'', 6''', 306) of separate impression punches (106). Said two rings (6, 6', 6'', 6''') of impression punches (106) are freely rotatable about the axis of the roller (1), independently of each other, in order to provide many combinations of axially adjacent impression punches (106), while means (11, 11', 7, 8, 9, 401, 206) are provided for the disengageable rotary coupling of the rings (6, 6', 6'', 6''') with the roller (1). <IMAGE>
