Adhesive roller construction

Abstract

An adhesive roller having an elongated strip with a backing layer and an adhesive layer overlying at least a portion of one side of the backing layer. The strip has a first end, a second end, and two spaced apart sides. The strip is wound from its first end and to its second end into a tubular cylindrical roll in which multiple layers of the strip overlap each other. An elongated perforation is formed transversely across the strip at spaced intervals therealong. This perforation, furthermore, includes an outwardly protruding tab at a position intermediate the ends of the perforation. This tab registers with a non-adhesive portion of an immediately inner layer of the strip so that the tab pops out from the roll to facilitate removal of the individual layers of the roller.

         4 . The invention as defined in  claim 3  wherein said non-adhesive portion is positioned at a midpoint between the edges of said strip.  
     
     
         5 . The invention as defined in  claim 1  wherein said preventing means comprises a plurality of non-adhesive patches attached at spaced intervals to said strip so that each said patches registers with said tab on the immediately adjacent outer layer of said strip.  
     
     
         6 . The invention as defined in  claim 5  wherein each patch is constructed of a material which has shape memory.  
     
     
         7 . The invention as defined in  claim 6  wherein said patch has shape memory in a concave direction with respect to an outer surface of the roller construction.  
     
     
         8 . The invention as defined in  claim 1  wherein said preventing means comprises a release agent applied to an inwardly facing surface of each tab.  
     
     
         9 . The invention as defined in  claim 1  wherein said preventing means comprises a plurality of adhesive masked spots at spaced intervals to said strip so that each said masked spot registers with said tab on the immediately adjacent outer layer of said strip.  
     
     
         10 . The invention as defined in  claim 1  wherein said perforation set terminates short of at least one edge of said strip.  
     
     
         11 . The invention as defined in  claim 1  wherein said perforation set terminates short of both edges of said strip.  
     
     
         12 . The invention as defined in  claim 1  and comprising a tubular cylindrical roller support, said strip being wound around said roller support.  
     
     
         13 . The invention as defined in  claim 9  wherein said roller support is constructed of cardboard.  
     
     
         14 . The invention as defined in  claim 9  wherein said roller support is constructed of plastic.  
     
     
         15 . The invention as defined in  claim 1  wherein said perforation set comprises two aligned perforated sections, said tab being positioned between said perforated sections.  
     
     
         16 . The invention as defined in  claim 15  wherein said tab has a curvilinear portion which protrudes outwardly from said aligned sections.  
     
     
         17 . The invention as defined in  claim 1  wherein said perforation set comprises a plurality of perforations, said perforations varying in length from said tab and to the sides of said strip.  
     
     
         18 . The invention as defined in  claim 1  wherein said perforation comprises a continuous slit formed transversely across said strip.  
     
     
         19 . The invention as defined in  claim 6  wherein each spot is masked with ink.  
     
     
         20 . The invention as defined in  claim 6  wherein each spot is masked with a deadening agent containing silicone.  
     
     
         21 . The invention as defined in  claim 1  wherein said tabs on adjacent layers of said roller construction are circumferentially spaced from each other.  
     
     
         22 . The invention as defined in  claim 2  wherein said non-adhesive spots are oblong in shape.  
     
     
         23 . The invention as defined in  claim 1  wherein said tab comprises a patch having a release agent applied to a portion of the patch, said patch being applied to said strip so that said portion of said patch is positioned on one side of said perforation and a remainder of said patch is positioned on the other side of said perforation.  
     
     
         24 . The invention as defined in  claim 1  and comprising graphics applied to said tab.  
     
     
         25 . The invention as defined in  claim 1  wherein said tab has a shape associated with a particular business entity.  
     
     
         26 . The invention as defined in  claim 1  wherein said tab is aligned with an uncut portion of said perforation.  
     
     
         27 . The invention as defined in  claim 26  wherein said perforation set comprises a first cut extending from a point adjacent one edge of the strip to a point aligned with but short of the center of the tab, and a second cut extending from a point adjacent the other edge of the strip to a point aligned with but short of the center of the tab.  
     
     
         28 . The invention as defined in  claim 27  wherein each cut is curvilinear in shape.
