Adhesive roller assembly
View Patent ↗An adhesive roller for detritus removal having a tubular cylindrical adhesive roll formed by a plurality of overlapping spiral wound layers. Each layer has a backing substrate and an adhesive coating on an outwardly facing side of the sheet. A cover is removably disposed around and has an inner side in contact with the outermost layer of the adhesive roll. The cover has an adhesive release coating on its inner side to reduce adhesion between the cover and the outermost layer of the adhesive roll and two longitudinally extending edges positioned closely adjacent each other when the cover is disposed around the roll. The cover is formed by overlapping spiral wound strips. Additionally, a longitudinally extending adhesive retainer strip overlies the edges of the cover to detachably secure the covers together. A pull-tab is adhesively attached to one side of the retainer strip which enables the cover to be repeatedly removed from and reattached to the adhesive roll.
1. An adhesive roller assembly for detritus removal comprising:
a tubular cylindrical adhesive roll having a plurality of overlapping layers, each layer having a backing sheet and an adhesive coating on an outwardly facing side of said backing sheet;
a cover separate from said adhesive roll removably and replaceably disposed around and having one side in contact with an outermost layer of said adhesive roll, said cover being free of adhesive on an outwardly facing side of said cover, said cover having an adhesive release coating on said one side to reduce adhesion between said cover and said outermost layer of said adhesive roll, said cover having two longitudinally extending edges positioned closely adjacent each other when said cover is disposed around said roll;
a longitudinally extending adhesive retainer strip overlying said edges of said cover which detachably secure said cover edges together; and
a pull-tab adhesively attached along one side of said retainer strip.
2. The invention as defined in claim 1 wherein said overlapping layers of said adhesive roll are spiral wound.
3. The invention as defined in claim 1 wherein said cover is generally rectangular in shape.
4. The invention as defined in claim 1 wherein said cover comprises a paper layer and an adhesive tape layer.
5. The invention as defined in claim 4 wherein said paper layer and said tape layer are spiral wound.
6. The invention as defined in claim 5 wherein said tape layer comprises a clear tape layer.
7. A method of manufacturing an adhesive roller for detritus removal comprising the steps of:
spiral winding overlapping adhesive strips around a cylindrical core so that each strip forms a layer about the core, each adhesive strip having a backing layer and an adhesive coating on an outwardly facing surface of said backing layer;
spiral winding a seperate cover assembly free of adhesive on anoutwardly facing side around an outermost layer of said overlapping adhesive strips, said cover assembly having an adhesive release coating on a side of the cover assembly in contact with said adhesive strip;
forming a longitudinal slit through said cover assembly thereby forming abutting edges of said cover assembly; and
applying a longitudinally extending adhesive retainer strip along and overlying said abutting edges of said cover assembly and which detachably secures said cover edges together assembly.
8. The invention as defined in claim 7 and further comprising the step of attaching a pull-tab to one side of said retainer strip.
9. The invention as defined in claim 7 wherein said step of spiral winding said cover assembly further comprises the steps of:
spiral winding a substrate having an outwardly facing side that is free of adhesive around the outermost layer of said overlapping adhesive strips; and
spiral winding an adhesive tape having spaced apart edges around said substrate, said adhesive tape being dimensioned so that said adhesive tape edges are adjacent each other.
