  • Apparatus for producing a strip of laminated sheet material
    Patent number: 4666550
    Abstract: Apparatus is provided for laminating a strip of foil to each edge of a double-width strip of cigarette tipping paper. A double-width strip of foil having a water-activated adhesive on one side is slit into two strips which are separated to the width of the tipping paper, run over a water-applying drum, and laid down on the tipping paper. The apparatus includes a low friction air bearing strip guiding system and a feedback system for controlling strip tension. The water-applying drum has a textured surface to retain sufficient water to activate the adhesive without overwetting the foil strip.
