Definitions

• the present invention relates to an apparatus for applying an adhesive layer to an adhesive roll in a contact cleaning device, in particular, but not exclusively, to an apparatus including an applicator or an apparatus including a cartridge with an applicator.
• the present invention also relates to apparatus for contact cleaning a substrate surface including a contact cleaning roller, an adhesive roll and an applicator.
• Contact cleaning is used to clean substrate surfaces. Once cleaned, the substrate surface may be used in a variety of sophisticated processes such as in the manufacturing of electronics, photovoltaics and flat panel displays. Usually, a rubber or elastomeric cleaning roller is used to remove contaminating particles from a substrate surface and an adhesive roll can then be used to remove the contaminating particles or debris from the cleaning roller. This allows the cleaning roller to maximise its efficiency in removing contaminating particles from the substrate surface.
• an adhesive roll typically comprises a wound length, or sheeted lengths, of substrate material wrapped around a core.
• the substrate material includes an adhesive side which can be used to remove or collect the debris from the surface of the cleaning roller.
• the adhesive roller removes debris, the outermost length of the adhesive material will lose effectiveness until performance falls below a required threshold. When the performance falls below the required threshold the adhesive material is spent and must be removed. This may be done by a user cutting away the outer circumference of the used portion of a continuous length of adhesive material, leaving behind a new portion of continuous adhesive material for use. [0006] Alternatively, the adhesive material is sheeted and, when the outermost sheet of the adhesive material is spent it is removed by simply tearing away the contaminated sheet to reveal a fresh, uncontaminated sheet of adhesive material. [0007] A further known alternative is disclosed in W02006133024, which employs a length of adhesive tape running between two spindles.
• the adhesive tape is continually applied to and then removed from the surface of cleaning roller in order to clean debris from it.
• the adhesive tape is used to engage an intermediary sheeted tape roll which cleans the cleaning roller. Engagement of the adhesive tape with the intermediary sheeted tape roll transfers accumulated particles as well as a spent sheet from the sheeted tape roll in order to renew the sheeted tape roll.
• a contact cleaning apparatus may require minimal or no user intervention or involvement.
• a contact cleaning apparatus may be fully automated, in particularly when the outer surface of an adhesive roll requires restoring.
