A method of manufacturing an adhesive tape (32, figure 10), comprising a tape slitting operation in which, using a tape slitting head 92, a web 30 having a plurality of transversely spaced adhesive stripes (16, figure 2) is slit into a plurality of adhesive tapeswhich each have an adhesive stripe. The tape slitting is controlled such that the web is slit in register with the adhesive stripes by monitoring the transverse position of at least a part of at least one adhesive stripe and adjusting the relative transverse position between the tape slitting head and the web in response thereto. There is also disclosed apparatus for manufacturing an adhesive tape. Preferably, the adhesive stripes have (UV) photoluminiscent or fluorescent properties, which facilitate the optical monitoring of the position of the stripes. The adhesive stripes may have a central adhesive region disposed between non-adhesive regions. The adhesive stripes may be applied in register with one another using a coating cylinder. The slitting elements blades or knives with fixed spacing. |
