Abstract

Apparatus ( 10 ) for automatically removing an exhausted layer of adhesive material from an adhesive roll ( 12 ), said apparatus comprising an adhesive roll ( 12 ) comprising at least one layer of adhesive material ( 22 ), said at least one adhesive layer having first and second mutually opposing faces, said second face releasably attached to said adhesive roll and having a first adhesion force between said second face and an said adhesive roll; and an adhesive layer removal mechanism ( 14 ) comprising an outer surface arranged to operably engage said at least one layer of adhesive material of said adhesive roll and remove the same from said adhesive roll, said outer surface having a second adhesion force between said outer surface and said at least one layer of adhesive material, wherein said second adhesion force is greater than the first adhesion force.

First claim

1 - 13 . (canceled)

14 . An apparatus for automatically removing an exhausted layer of adhesive material from an adhesive roll, the apparatus comprising:
an adhesive roll comprising at least one layer of adhesive material, the at least one adhesive layer having first and second mutually opposing faces, the second face releasably attached to the adhesive roll and having a first adhesion force between the second face and an the adhesive roll; and an adhesive layer removal mechanism comprising an outer surface arranged to operably engage the at least one layer of adhesive material of the adhesive roll and remove the same from the adhesive roll, the outer surface having a second adhesion force between the outer surface and the at least one layer of adhesive material, wherein the second adhesion force is greater than the first adhesion force.

15 . The apparatus according to claim 14 , wherein the adhesive layer removal mechanism is configured to be moveable between a first configuration, in which the adhesive layer removal mechanism operably engages the adhesive roll, and a second configuration, in which the adhesive layer removal mechanism is disengaged from the adhesive roll.

16 . The apparatus according to claim 14 , wherein the adhesive layer removal mechanism comprises a pick up device.

17 . The apparatus according to claim 16 , wherein the pick up device is a roller.

18 . The apparatus according to claim 14 , further comprising a waste removal mechanism arranged to operably engage the at least one layer of adhesive material on the adhesive layer removal mechanism and remove the same from the adhesive sheet removal mechanism.

19 . The apparatus according to claim 18 , wherein the waste removal mechanism comprises one or more of: a rewind roller and a tangential blade.

20 . The apparatus according to claim 14 , wherein the at least one layer of adhesive material comprises a continuous adhesive sheet.

21 . The apparatus according to claim 14 , wherein the at least one layer of adhesive material comprises a plurality of adhesive sheets operably coupled to one another at adjoining ends thereof.

22 . The apparatus according to claim 14 , wherein the first face of at least one layer of adhesive material of the adhesive roll is configured to contact at least one cleaning roller so as to remove debris from the first face.

23 . A contact cleaning apparatus comprising one or more contact cleaning rollers, one or more adhesive rolls configured and arranged to remove debris from the one or more contact cleaning rollers and the apparatus according to claim 1 for automatically removing an exhausted layer of adhesive material from the adhesive roll(s).

24 . A method for automatically removing an exhausted layer of adhesive material from an adhesive roll, the method comprising:
providing an adhesive roll; providing an adhesive layer removal mechanism; operably engaging the adhesive layer removal mechanism with the at least one layer of adhesive material of the adhesive roll; and removing, by the adhesive layer removal mechanism, the operably engaged at least one layer of adhesive material from the adhesive roll, thereby exposing a clean layer of adhesive material on the adhesive roll.

25 . The method according to claim 24 , wherein the method further comprises the step of providing a waste removal mechanism and the step of removing, by the waste removal mechanism, the operably engaged at least one layer of adhesive material from the adhesive layer removal mechanism.

26 . The method according to claim 24 , wherein the method further comprises:
providing a contact cleaning apparatus comprising one or more contact cleaning rollers; and operably engaging the at least one layer of adhesive material of the adhesive roll with the one or more contact cleaning rollers so as to remove debris therefrom.
