Abstract (en)

Tipping papers (3) used to join filter plugs and cigarette sticks (7) are obtained from a continuous strip (4) caused to advance by pinch rolls (17) along a feed path (P) in a given direction (D), and conveyed at a first tension (Tnl) through a cutting station (5) at which the individual papers (3) are separated by cuts made at a predetermined frequency and synchronously with the operation of a diverter element (24) located between the pinch rolls (17) and the cutting station (5). The diverter element serves to bring about a cyclical variation in the first tension of the strip (4) and is embodied as a cam (25) with a profile (27) having two distinct lobes (28, 29), made to oscillate between two limit positions (PA1, PA2) in which the lobes (28, 29) interact alternately with the strip, diverting it and causing it to assume the first tension (Tn1), and passing through an intermediate position (PAO) in which the strip is allowed to assume a second tension (Tn2) slacker than the first; the cam (25) completes each full cycle between the two limit positions (PA1, PA2) at a frequency equivalent to half the frequency with which the papers are cut. <IMAGE>
