Abstract
Abstract The winding of a tacky sealant strip by applying a non-sticking liner into contact with one surface of the strip such that the liner provides marginal edges on either side of the sealant strip. The strip and liner are wound progressively into a reel such that the liner maintains a clearance space between adjacent sealant strips while simultaneously providing a non-sticking circumferential surface for a second wound row of sealant strip material. Additional rows of such liner and strip are progressively wound on such reel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
A method of winding a tacky sealant strip that has an upper surface, a lower surface and a pair of side surfaces comprising the steps of feeding said sealant strip; feeding an indeterminate length liner into abutting contact with said lower surface of said strip of tacky sealant to form a tape wherein said liner is of greater width than said strip to extend marginal edge portions of said liner strip on either side of said longitudinally extending strip; feeding said strip and said liner as a tape into contact with the hub of a flanged rotatable reel with said upper tacky surface of said strip fed into abutting contact with said hub; and winding said tape progressively onto said hub to form a single row with said marginal edges of said liner contacting one of said side surfaces of an adjacent sealant strip for spacing said windings of said sealant strip to provide spacing between adjacent side surfaces of said sealant strip.
Claim 2
Independent Claim
163 words
A method of winding a tacky sealant strip that has an upper surface, a lower surface and a pair of side surfaces comprising the steps of feeding said sealant strip; feeding an indeterminate length liner into abutting contact with said lower surface of said strip of tacky sealant to form a tape wherein said liner is of greater width than said strip to extend marginal edge portions of said liner strip on either side of said longitudinally extending strip; feeding said strip and said liner as a tape into contact with the hub of a flanged rotatable reel with said upper tacky surface of said strip fed into abutting contact with said hub; and winding said tape progressively onto said hub to form a single row with said marginal edges of said liner contacting one of said side surfaces of an adjacent sealant strip for spacing said windings of said sealant strip to provide spacing between adjacent side surfaces of said sealant strip.
Claim 3
Dependent Claim
92 words
A method of winding a tacky sealant strip as set forth in claim 1 wherein said sealant strip with said liner is wound circumferentially around said first formed single row with the tacky surface of said strip opposite said liner into abutting contact with the liner of said first formed single row and with said marginal edges of said liner contacting one of said side surfaces of an adjacent sealant strip for spacing the windings of said sealant strip to provide a spacing between adjacent tacky side surfaces of said sealant strip.
Claim 4
Dependent Claim
64 words
A method of winding a tacky sealant strip as set forth in claim 2 wherein said sealant strip with said liner is wound in successive rows onto said reel wherein said liner separates the successive rows of said sealant strip and said marginal edges of said liner contacts adjacent surfaces of sealant strips providing spacing between laterally adjacent side surfaces of said sealant strips.
Claim 5
Dependent Claim
41 words
A method of winding a tacky sealant strip as set forth in claim 3 wherein said marginal edges of said liner overlap each other on said hub to reinforce the support between successive rows of wind up of said sealant strips.
Claim 6
Independent Claim
128 words
A method of winding a tacky sealant strip having a quadrilateral cross-sectional shape onto a reel having a hub with flanged ends thereon comprising the steps of feeding said tacky sealant strip in a first direction; feeding a non-sticking liner into abutting contact with one running surface of said sealant strip with said liner having a width greater than said sealant strip to form marginal edge portions on either side of a pair of side surfaces on said sealant strip, winding said sealant strip with said liner thereon as a single row across and into contact with said hub of said reel with said marginal edge portions of said liner contacting one of said side surfaces of an adjacent sealant strip to provide spacing between adjacent sealant strips.
Claim 7
Independent Claim
128 words
A method of winding a tacky sealant strip having a quadrilateral cross-sectional shape onto a reel having a hub with flanged ends thereon comprising the steps of feeding said tacky sealant strip in a first direction; feeding a non-sticking liner into abutting contact with one running surface of said sealant strip with said liner having a width greater than said sealant strip to form marginal edge portions on either side of a pair of side surfaces on said sealant strip, winding said sealant strip with said liner thereon as a single row across and into contact with said hub of said reel with said marginal edge portions of said liner contacting one of said side surfaces of an adjacent sealant strip to provide spacing between adjacent sealant strips.
