Claims
- 1. A device substantially enclosed in a portable container for applying a strip of double-sided pressure sensitive tape to a receiving surface, said device including a rotatable supply roll of composite tape consisting of a layer of double-sided pressure sensitive adhesive adhered to a strippable backing layer, a rotatable transfer roller including a cylindrical outer surface having a portion exposed outwardly of said container, said transfer roller receiving said adhesive layer and applying same to a receiving surface, said transfer roller being the sole driving means for movement of said composite tape and said backing layer being freely movable upon its release from said double-sided pressure sensitive tape, said outer surface having poor affinity for adhering to said adhesive tape, a stationary tapering nose having a rounded tip with a return bend surface spaced apart from the surface of said transfer roller generally the thickness of said double-sided pressure sensitive tape, a first channel leading from said supply roll to said tip for said composite tape, a second channel leading from said tip to a disposal site for said backing layer which is freely movable after being released from said double-sided pressure sensitive tape, a brake member normally bearing against said transfer roller for inhibiting rotation thereof except during application of said strip to a receiving surface, and selective means for releasing said brake member.
- 2. The device of claim 1 wherein said second channel terminates in an exit port leading to outside said container.
- 3. The device of claim 1 wherein said second channel leads to an interior space in said container adapted to receive said backing tape.
- 4. The device of claim 1 wherein said selective means for releasing said brake member includes a movable device separate from said container and adapted to selectively bear against said brake member.
- 5. The device of claim 1 wherein said portable container is a replaceable component in an apparatus for spooling continuously travelling webs of paper, intermittently cutting said web with a cutting tape, and transferring said cut web to an empty spool.
- 6. The device of claim 1 wherein said portable container is a cassette with built-in structure for rotatably supporting said supply roll, and for providing a pivot for said brake member.
- 7. The device of claim 1 wherein said brake member includes a pivotable lever arm including a friction face that is pivotable to bear against or be spaced apart from said cylindrical outer surface.
- 8. The device of claim 1 wherein said cylindrical outer surface is a silicone rubber.
- 9. The device of claim 1 which additionally includes a sharp edge positioned transversely to the movement of said double-sided adhesive tape and positioned downstream from said nose tip and very close to the double-sided adhesive temporarily adhering to said transfer roller, said sharp edge being adapted to assure separation of said backing layer from said double-sided adhesive layer.
- 10. A device substantially completely enclosed in a cassette container and adapted to deliver and to apply to a receiving surface a strip of pressure-sensitive adhesive, said device including a freely rotatable roll of a composite tape consisting of a continuous layer of double-sided adhesive adhering to a continuous strip of backing layer readily strippable from said adhesive; a rotatable transfer roll being the sole driving means for movement of said composite tape and adapted to receive said layer of adhesive from said composite tape and apply it to a receiving surface as the transfer roll rotates while releasing said backing layer to free movement, a portion of said transfer roll extending outwardly from said cassette container; a first channel for guiding said composite tape from said supply roll to said transfer roll; a second channel for guiding said backing layer from said transfer roll to disposal zone for said backing layer, a return bend rounded surface joining said first channel to said second channel at a position closely adjacent said transfer roll, and a frictional braking means for preventing rotation of said transfer roll except during application of said strip to a receiving surface.
- 11. The device of claim 10 further comprising a receiving surface, said receiving surface being one surface of an elongated narrow paper cutting tape employed in the paper industry in transferring the wind up of a continuous web of paper from one wind up roll to another.
- 12. The device of claim 10 wherein said braking means includes a spring biased pivotable lever having said frictional face as a component thereof and which includes movable member adapted to overcome said spring bias and move said frictional face away from contact with said transfer roll.
- 13. The device of claim 12 wherein said movable member is a hand controlled pivotable lever.
- 14. The device of claim 12 wherein said movable member is a plunger separate from said cassette container and adapted to automatically apply a force contrary to said spring bias when it is desired to apply said adhesive layer to said receiving surface.
- 15. The device of claim 10 which additionally comprises a doctor knife edge positioned closely adjacent to said return bend surface and positioned to assure stripping of said backing layer from said composite tape temporarily adhered to said transfer roll.
- 16. The device of claim 10 wherein said transfer roll includes a cylindrical surface of material having a positive but poor adherence to said layer of pressure-sensitive adhesive.
- 17. A device substantially enclosed in a portable container for applying a strip of double-sided pressure sensitive adhesive to a receiving surface, said device including a rotatable supply roll of composite tape consisting of a strip of double-sided pressure sensitive adhesive adhered to a strippable backing layer, a rotatable transfer roller having a cylindrical outer surface adapted to receive said double-sided pressure sensitive adhesive strip and apply it to a receiving surface, said outer surface of said transfer roller having poor affinity for adhering to said adhesive of said double-sided strip, a stationary tapering nose having a rounded tip with a return bend surface spaced apart from the surface of said transfer roller substantially the thickness of said double-sided adhesive strip, a first channel leading from said supply roll to said tip and a second channel leading from said tip to a disposal site for said backing layer, a sharp edge positioned transversely to the movement of said double-sided adhesive strip and positioned downstream from said nose tip and juxtaposed to said double-sided adhesive strip temporarily adhering to said transfer roller, said sharp edge assuring separation of said backing layer from said double-sided adhesive strip upstream from said sharp edge, said sharp edge passing said double-sided adhesive strip attached to said transfer roller while preventing said backing layer from passing between said sharp edge and said double sided adhesive strip attached to said transfer roller.
- 18. The device of claim 17 further including brake means for inhibiting movement of said strip of double-sided adhesive, and selective means for releasing said brake means to permit movement of said double-sided strip except during application of said strip to a receiving surface.
- 19. The device of claim 18 wherein said brake means includes a pivotable lever arm having a friction face that is pivotable to selectively bear against and spaced apart from said cylindrical outer surface.
- 20. The device of claim 19 wherein said brake means includes a spring biasing said friction face into engagement with said cylindrical outer surface, said cylindrical outer surface being a silicone rubber.
