a first supply roll rotatably mounted within said frame, said first supply roll carrying a wound up supply of an adhesive carrying substrate that has an adhesive carrying release surface coated with a layer of pressure-sensitive adhesive;
a second supply roll rotatably mounted within said frame, said second supply roll carrying a wound up supply of an adhesive mask substrate;
said adhesive carrying substrate being unwound from said first supply roll with a lead end portion thereof extending outwardly from the discharge side of said frame;
said mask substrate being unwound from said second supply roll with a lead end portion thereof extending outwardly from the discharge side of said frame adjacent the lead end portion of said carrying substrate;
said frame being constructed and arranged to enable the adhesive transfer operation to be initiated by manually grasping said frame with one hand and inserting a leading edge portion of the selected substrate between said adhesive carrying and mask substrates; and
pressure applying structure constructed and arranged such that the adhesive transfer operation can be continued while continuing to manually grasp said frame with one hand by manually grasping the lead end portions of said adhesive carrying and mask substrates at the discharge side of said frame with the other hand and manually pulling said lead end portions so as to advance said mask, adhesive carrying, and selected substrates together outwardly from the discharge side of said frame with said pressure applying structure applying pressure to said substrates being advanced through said device, thereby causing the pressure-sensitive adhesive on said adhesive carrying substrate to bond to the selected substrate.
2. A hand-held actuatorless adhesive transfer device according to claim 1 , wherein said mask substrate has a mask surface that engages the selected substrate and that has a greater affinity for adhesive bonding than the adhesive carrying release surface of said adhesive carrying substrate so that, after said selected substrate has advanced outwardly from the discharge side of said frame, said mask substrate and said carrying substrate can be peeled apart from one another so that any portions of the adhesive bonded to said mask surface remain bonded thereto and are removed from said adhesive carrying substrate, thereby leaving said selected substrate bonded to said carrying substrate with substantially no adhesive exposed around the periphery of said selected substrate so that said selected substrate can be peeled back from said carrying substrate and bonded to a surface as desired.
3. A hand-held actuatorless adhesive transfer device according to claim 1 , wherein said pressure applying structure comprises a first substrate engaging structure provided on said frame and a second substrate engaging structure provided on said frame;
said adhesive carrying substrate being unwound from said first supply roll and advanced between said substrate engaging structures with a surface thereof opposite said adhesive carrying release surface engaging said first substrate engaging structure; said adhesive mask substrate being unwound from said second supply roll and advanced between said substrate engaging structures with a surface thereof opposite said adhesive mask surface engaging said second substrate engaging structure;
said first and second substrate engaging structures being constructed and arranged to apply pressure to said adhesive carrying, adhesive mask, and said selected substrates as they are advanced therebetween to thereby cause the pressure-sensitive adhesive to bond to the selected substrate as aforesaid.
4. A hand-held actuatorless adhesive transfer device according to claim 3 , wherein said first and second substrate engaging structures are spaced apart from one another to define a substrate receiving slot, said substrate receiving slot having a width such that a combined thickness of said carrying, mask, and selected substrates being advanced therethrough causes said substrates to be compressed between said substrate engaging structure, thereby creating the pressure applied by said substrate engaging structures as aforesaid.
5. A hand-held actuatorless adhesive transfer device according to claim 1 , wherein said frame comprises a main frame portion and a cartridge removably mounted to said main frame portion;
said first and second supply rolls being rotatably mounted in said cartridge so that the removable mounting of said cartridge facilitates removal and said replacement of said first and second supply rolls in a single operation.
6. A hand-held actuatorless adhesive transfer device according to claim 4 , wherein said first substrate engaging structure is a plate-like rigid structure fixedly mounted within said cartridge and wherein said second substrate engaging structure is a cylindrical structure fixedly mounted within said cartridge.
7. A hand-held adhesive transfer device according to claim 1 , further comprising a cutting blade mounted at the discharge side of said frame in such a manner that the lead end portions of said substrates extending outwardly from the discharge side of said frame can be moved into engagement with said blade to sever said lead end portions.
8. A hand-held adhesive transfer device according to claim 7 , wherein said blade is serrated.
9. An adhesive transfer device for performing an adhesive transfer operation wherein adhesive is applied to a side edge portion of a selected substrate, said device comprising:
a frame having a feeding side and a discharge side;
a first supply roll rotatably mounted within said frame, said first supply raol carrying a wound up supply of an adhesive carrying substrate that has an adhesive carrying release surface coated with a layer of pressure-sensitive adhesive;
a second supply roll rotatably mounted within said frame, said second supply roll carrying a wound up supply of an adhesive mask substrate;
said frame having a substrate receiving opening extending from the feeding side thereof to the discharge side thereof and opening to an exterior of said frame, said substrate receiving opening being positioned and configured to enable a corner portion of the selected substrate at which a leading edge portion and the side edge portion of said selected substrate intersect to be inserted between said adhesive carrying and mask substrates; and
pressure applying structure constructed and arranged such that, when the corner portion of the selected substrate is inserted between said adhesive carrying and mask substrates as aforesaid, the adhesive transfer operation can be performed by advancing said mask substrate, said adhesive carrying substrate, and the side edge portion of said selected substrate together through said device and outwardly from the discharge side of said frame with said pressure applying structure applying pressure to said substrates being advanced through said device, thereby causing the pressure-sensitive adhesive on said adhesive carrying substrate to bond to the side edge portion of the selected substrate.
10. An adhesive transfer device according to claim 9 , wherein said mask substrate has a mask surface that engages the selected substrate and that has a greater affinity for adhesive bonding than the adhesive carrying release surface of said adhesive carrying substrate so that, after said selected substrate has advanced outwardly from the discharge side of said frame, said mask substrate and said carrying substrate can be peeled apart from one another so that any portions of the adhesive bonded to said mask surface remain bonded thereto and are removed from said adhesive carrying substrate, thereby leaving said side edge portion of said selected substrate bonded to said carrying substrate with substantially no adhesive exposed around the side edge portion of said selected substrate so that said selected substrate can be peeled back from said carrying substrate and bonded to a surface as desired.
11. An adhesive transfer device according to claim 9 , wherein said pressure applying structure comprises a first substrate engaging structure provided on said frame and a second substrate engaging structure provided on said frame;
