Abstract
Abstract Dispenser for film tapes such as pressure-sensitive adhesive tapes includes a rotatable mounting for a coil of tape so that the tape may be progressively uncoiled upon rotation of the coil and a selective device for dispensing portions of the tape as it is uncoiled. Static electricity on the tape is neutralized during uncoiling by either drawing the tape past a number of electrical conductors, e.g., grounded wires, disposed near the tape or applying to the tape a static neutralizing volatile fluid which is permitted to evaporate before or as the tape is dispensed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
Apparatus for dispensing film tape while neutralizing static electricity thereon, comprising: a. means rotatably mounting a coil of said tape such that said tape may be progressively uncoiled upon rotation of said coil; and b. means for selectively dispensing portions of said tape as said tape is progressively uncoiled from said coil; wherein the improvement comprises: c. a plurality of electrically conductive means disposed adjacent at least one side of said tape transversely thereto between said mounting and dispensing means for neutralizing static electricity on said tape as said tape is uncoiled from said coil, said plurality of conductive means comprising a multiplicity of pointed conductive members extending toward the adjacent side of the tape, said members being electrically connected together and having means for connecting them to ground.
Claim 2
Dependent Claim
129 words
Apparatus for dispensing film tape while neutralizing static electricity thereon, comprising: a. means rotatably mounting a coil of said tape such that said tape may be progressively uncoiled upon rotation of said coil; and b. means for selectively dispensing portions of said tape as said tape is progressively uncoiled from said coil; wherein the improvement comprises: c. a plurality of electrically conductive means disposed adjacent at least one side of said tape transversely thereto between said mounting and dispensing means for neutralizing static electricity on said tape as said tape is uncoiled from said coil, said plurality of conductive means comprising a multiplicity of pointed conductive members extending toward the adjacent side of the tape, said members being electrically connected together and having means for connecting them to ground.
Claim 3
Dependent Claim
26 words
Apparatus according to claim 1, wherein said pointed members are wires grouped in tufts and extending toward but spaced from the adjacent side of said tape.
Claim 4
Dependent Claim
35 words
Apparatus according to claim 1, wherein said pointed members are wires grouped into tufts, each wire of said tuft being of substantially the same length and extending substantially toward the adjacent side of said tape.
Claim 5
Dependent Claim
27 words
Apparatus according to claim 3, further comprising insulating means supporting the tufts of wires, said tufts of wires being arranged about and extending from said insulating means.
Claim 6
Dependent Claim
18 words
Apparatus according to claim 1, wherein said electrically conductive means are disposed adjacent both sides of said tape.
Claim 7
Dependent Claim
42 words
Apparatus according to claim 2, further comprising insulating means affixed to said mounting means near both sides of said tape, said electrically conductive means being arranged with said tufts of wires extending toward both sides of said tape from said insulating means.
Claim 8
Dependent Claim
86 words
Apparatus according to claim 1, which includes insulating means spaced from and extending across the path of the tape and in which said plurality of electrically conductive means comprise a multiplicity of wires carried by said insulating means and extending therefrom substantially toward the adjacent side of the tape at localities distributed across said path and in sufficient proximity to the tape for neutralizing static electricity on said tape as said tape is dispensed from said dispenser and just prior to its application to a substrate.
Claim 9
Independent Claim
118 words
A method of dispensing adhesive tape having pressure-sensitive adhesive on at least one side thereof, comprising the steps of: a. rotatably mounting a coil of said tape such that said tape may be progressively uncoiled upon rotation of said coil; and b. selectively dispensing portion of said tape as said tape is progressively uncoiled from said coil; wherein the improvement comprises the step of: c. neutralizing static electricity on said tape between said mounting and dispensing steps by drawing the tape, as it is dispensed, past a plurality of pointed conductors disposed in spaced relation to the tape path and coacting to effect neutralization of charge from the tape, and conducting excess charge from said conductors to ground.
Claim 10
Independent Claim
118 words
A method of dispensing adhesive tape having pressure-sensitive adhesive on at least one side thereof, comprising the steps of: a. rotatably mounting a coil of said tape such that said tape may be progressively uncoiled upon rotation of said coil; and b. selectively dispensing portion of said tape as said tape is progressively uncoiled from said coil; wherein the improvement comprises the step of: c. neutralizing static electricity on said tape between said mounting and dispensing steps by drawing the tape, as it is dispensed, past a plurality of pointed conductors disposed in spaced relation to the tape path and coacting to effect neutralization of charge from the tape, and conducting excess charge from said conductors to ground.
