Means (34) are provided to define for the web (4), on a first conveyor belt (2) and upstream of a nip line defined by two adjacent rollers (35, 61), a section (22) inclined towards the nip line. The nip roller (35) associated with the first belt (2) causes said belt to make a turn of an angle (B) comprised between 90� and 180�.
