Abstract
Abstract A process and apparatus is disclosed for removing adhesive tape such as is used in masking PC boards during plating operations, the apparatus including rollers carrying an adhesive band which is brought into pressure contact with the adhesive tape. The PC board is moved past the rollers to pick up the adhesive tape and strip it by wind-up on the roller periphery. Successive windings of the exposed adhesive undersurface of the tape act to enable successive removal cycles. The leading ends of the tape are easily strippable to facilitate removal, as by the use of a release agent, or by providing a localized area at the leading end of the tape which carries a mildly adherent adhesive.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
114 words
A process for removing lengths of pressure sensitive tape from opposite side surfaces of a body, wherein said tape lengths are joined by a joining portion extending about a leading surface of said body, comprising the steps of: establishing localized leading areas of said tape lengths to be mildly adherent to said body; severing said joining portion; passing said body between a pair of opposing rollers, each carrying an adhesive band about the periphery thereof with said lengths of tape in registry with said adhesive bands while urging said rollers into pressure contact therewith; and, rotating said rollers while in engagement with said surfaces to cause said body to be advanced between said rollers.
Claim 2
Dependent Claim
114 words
A process for removing lengths of pressure sensitive tape from opposite side surfaces of a body, wherein said tape lengths are joined by a joining portion extending about a leading surface of said body, comprising the steps of: establishing localized leading areas of said tape lengths to be mildly adherent to said body; severing said joining portion; passing said body between a pair of opposing rollers, each carrying an adhesive band about the periphery thereof with said lengths of tape in registry with said adhesive bands while urging said rollers into pressure contact therewith; and, rotating said rollers while in engagement with said surfaces to cause said body to be advanced between said rollers.
Claim 3
Dependent Claim
40 words
The process according to claim 1 wherein said step of establishing mildly adherent localized areas of said tape lengths to be mildly adherent to said body comprises the step of treating said body with a release agent at said areas.
Claim 4
Dependent Claim
32 words
The process according to claim 1 wherein said step of establishing mildly adherent localized areas of said tape lengths comprising the step of forming said tape with regions of mildly adherent adhesive.
Claim 5
Dependent Claim
25 words
The process according to claim 1 wherein said rollers are moved from a non-engaging position to a position in pressure contact with said body surfaces.
Claim 6
Dependent Claim
27 words
The process according to claim 4 wherein said rollers are pivoted to swing from a non-engaging position to a position in pressure contact with said body surfaces.
Claim 7
Dependent Claim
73 words
The process according to claim 5 wherein said body is moved to an approach position to approach said rollers, sensing said approach position and causing said rollers to move to pressure contact said body when said body has reached a position whereat the leading edge of said body is able to be contacted by pivoting movement of said rollers, to thereby bring the outer surfaces thereof into pressure contact with said body surfaces.
Claim 8
Dependent Claim
37 words
The process according to claim 4 wherein said rollers are translated from a relatively remote position from each other to more proximate position with respect to each other to establish said pressure contact with said body surfaces.
Claim 9
Dependent Claim
28 words
The process according to claim 1 wherein double-faced adhesive tape is applied to each of said rollers to cause each of said rollers to carry said adhesive band.
Claim 10
Dependent Claim
124 words
A process for applying and removing pressure adhesive masking tape from printed circuit boards from a leading edge and sides adjacent thereof, the process including the steps of: applying a length of tape about said leading edge and along said sides; establishing localized areas of mild adherence of said tape on either side of said printed circuit board adjacent said leading edge; severing said tape at said leading edge; introducing said leading edge of said board between a pair of opposed rollers each carrying a band of adhesive and passing said board therebetween while urging said adhesive bands into pressure contact with said severed tape lengths, whereby said tape lengths are removed by adherence to said adhesive bands and winding up on said rollers.
Claim 11
Dependent Claim
124 words
A process for applying and removing pressure adhesive masking tape from printed circuit boards from a leading edge and sides adjacent thereof, the process including the steps of: applying a length of tape about said leading edge and along said sides; establishing localized areas of mild adherence of said tape on either side of said printed circuit board adjacent said leading edge; severing said tape at said leading edge; introducing said leading edge of said board between a pair of opposed rollers each carrying a band of adhesive and passing said board therebetween while urging said adhesive bands into pressure contact with said severed tape lengths, whereby said tape lengths are removed by adherence to said adhesive bands and winding up on said rollers.
Claim 12
Dependent Claim
24 words
The process according to claim 9 further including the step of rotating each of said rollers to cause said board to be passed therebetween.
Claim 13
Dependent Claim
113 words
A process for applying and removing a length of adhesive tape from the surface of a body comprising the steps of: applying a release compound to a region at one end of the area to which the tape is to be applied; applying said length of tape to said area with one end thereof overlying said region; bringing a roller carrying an adhesive outer band into pressure contact with said end of said tape overlying said regions; and, relatively moving said roller and said body so as to pass said roller along the length of said tape while maintaining said pressure contact, whereby removing said tape by adhesion and wind-up on said roller.
Claim 14
Dependent Claim
113 words
A process for applying and removing a length of adhesive tape from the surface of a body comprising the steps of: applying a release compound to a region at one end of the area to which the tape is to be applied; applying said length of tape to said area with one end thereof overlying said region; bringing a roller carrying an adhesive outer band into pressure contact with said end of said tape overlying said regions; and, relatively moving said roller and said body so as to pass said roller along the length of said tape while maintaining said pressure contact, whereby removing said tape by adhesion and wind-up on said roller.
