Abstract
The applicator roll is provided with two recesses to apply uniform layers of glue to a travelling stream of tipping paper. In addition, the applicator roll has a series of spaced apart grooves in each recess so as to apply additional stripes of glue onto the tipping paper near the edges. The additional stripes of glue provide for a more secure bonding of the tipping paper to the tobacco column of the filter cigarette construction.
