There is disclosed a method of manufacturing an adhesive tape (32), comprising: printing a print pattern (14) including at least one printed datum (15) onto a web; applying onto the web a plurality of transversely spaced adhesive stripes (16) using an adhesive stripe applicator; and controlling adhesive stripe application such that the adhesive stripes (16) are applied in register with the print pattern (14) by monitoring the transverse position of at least a part of at least one printed datum (15) and adjusting the relative transverse position between the adhesive stripe applicator and the web in response thereto. The method also comprises a tape slitting operation in which, using a tape slitting head (92), the web is slit into a plurality of adhesive tapes (32) which each have an adhesive stripe (16); and controlling the tape slitting such that the web is slit in register with the print pattern (14) by monitoring the transverse position of at least a part of at least one printed datum (15) and adjusting the relative transverse position between the tape slitting head (92) and the web in response thereto.
A method of manufacturing an adhesive tape, comprising:
A method according to any preceding claim, wherein the or each printed datum extends in the web direction.
A method according to any preceding claim, wherein the print pattern is printed using one or more print cylinders.
A method according to any preceding claim, wherein the print pattern is printed using a gravure printing process.
A method according to any preceding claim, wherein the adhesive stripes are applied in register with one another.
A method according to any preceding claim, wherein the adhesive stripe applicator comprises a coating cylinder.
A method according to any preceding claim, wherein the adhesive stripes are applied using a gravure coating process.
A method according to any preceding claim, wherein controlling the adhesive stripe application comprises optically monitoring the transverse position of at least a part of at least one printed datum.
A method according to any preceding claim, wherein adjusting the relative transverse position between the adhesive stripe applicator and the web comprises transversely moving the web.
A method according to any preceding claim, wherein controlling the tape slitting comprises optically monitoring the transverse position of at least a part of at least one printed datum.
A method according to any preceding claim, wherein adjusting the relative transverse position between the tape slitting head and the web comprises transversely moving the tape slitting head.
A method according to any preceding claim, wherein the web is slit at positions in between adjacent adhesive stripes such that each adhesive tape comprises a central adhesive region disposed between non-adhesive edge regions.
A method according to any preceding claim, wherein the tape slitting head comprises a plurality of transversely spaced slitting elements.
A method according to any preceding claim, further comprising rewinding each adhesive tape onto a reel.
A method according to any preceding claim, further comprising applying a release coating onto the opposite side of the web to the side to which the adhesive stripes are applied.
A method according to any preceding claim, wherein the web subject to the tape slitting operation is a narrower web of the web to which the print pattern and/or adhesive stripes are applied to.
A method according to any preceding claim, further comprising a primary slitting operation, which is carried out prior to the tape slitting operation, in which, using a primary slitting head, the web is slit into a plurality of narrower webs which each have a plurality of transversely spaced adhesive stripes, wherein each narrower web is subsequently subject to the tape slitting operation.
An apparatus for manufacturing an adhesive tape, the apparatus comprising:
A method of manufacturing an adhesive tape or an apparatus for manufacturing an adhesive tape substantially as described herein with reference to the accompanying drawings.
