ABSTRACT:
Adhesive tapes 10 are automatically attached to closing sides 12 of folding cartons 11 which the cartons are transported. An adhesive tape 10 is pulled off a reel and pressed onto a folding carton under tension by means of pressure rollers. A pressure roller 26 presses an end leg 39 of the adhesive tape 10, which is projecting from the folding carton 11 at a rear side thereof, against a transversely directed side face 40 of the folding carton 11. When an adhesive tape 10 made of unstable carrier material are used, there is a danger of the tape creasing or curling up, especially at end portions thereof. To overcome this problem, a smoothing device in the form of a stationary suction head 41 is provided. The adhesive tape 10 slides along this smoothing device, such that at the final stage, the projecting end leg 39 is temporarily held in smooth and straight position until it is taken over by the pressure roller 26.
