Abstract
Abstract A combination package for use by coil manufacturers required to wind coils of wire at relatively high speed and constant tension. The package comprises a cylindrical container having a spool of wire enclosed therein, the spool adapted to be maintained in a vertical disposition during the dispensing of the wire, the wire adapted to be stripped off of the upper end of the spool through a central passageway in the cover of the container. A wire tensioning device is fixedly connected to the upper end of the spool coaxial therewith, this device comprising a disc having a plurality of radially extending resilient filaments that protrude beyond the periphery of the upper end of the spool. The upper end of the spool is a conventional annular flange. As the wire is stripped off the spool in a rotary movement, it strikes and deflects the filaments while moving around the upper annular flange. The impedance to free stripping produces the tension in the wire, such tension being a factor of the wire gauge, the thickness and density of filaments and to a much lesser degree, the diameter of the discs and the speed of stripping of the wire. The manufacturer of the package furnishes the entire combination with preset tension capability to the coil manufacturer. Various structures of wire tensioning devices are disclosed including axially spaced multiple discs and rings of filaments installed on the interior of the housing overlying the upper flange end of the spool.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
200 words
A package for dispensing wire with preset tension comprising: a. a generally cylindrical housing having an upper wall with a central passageway forming a cover; b. a spool of coiled wire having at least an upper annular flange end, the spool and associated flange end being nonrotatably secured in the housing coaxially therewith and the housing having a wall surrounding the annular flange and spaced therefrom to provide an annular wire confining and unreeling space between the flange and wall; and c. internal wire tensioning means including at least one disc member nonrotatably secured to the upper flange and having a plurality of elongate resilient filaments thereon extending radially across said annular space impeding the normal unwinding of the wire and adapted to be struck and deflected momentarily by the rotary movement of wire being pulled out of said passageway and passing along the periphery of said flange through said annular space while being unreeled to apply a preset tension value to the wire, the density and size of said filaments being so related to the gauge of wire and the geometric characteristics of the package that the tension of the wire during its unreeling will be constant and predetermined.
Claim 2
Dependent Claim
200 words
A package for dispensing wire with preset tension comprising: a. a generally cylindrical housing having an upper wall with a central passageway forming a cover; b. a spool of coiled wire having at least an upper annular flange end, the spool and associated flange end being nonrotatably secured in the housing coaxially therewith and the housing having a wall surrounding the annular flange and spaced therefrom to provide an annular wire confining and unreeling space between the flange and wall; and c. internal wire tensioning means including at least one disc member nonrotatably secured to the upper flange and having a plurality of elongate resilient filaments thereon extending radially across said annular space impeding the normal unwinding of the wire and adapted to be struck and deflected momentarily by the rotary movement of wire being pulled out of said passageway and passing along the periphery of said flange through said annular space while being unreeled to apply a preset tension value to the wire, the density and size of said filaments being so related to the gauge of wire and the geometric characteristics of the package that the tension of the wire during its unreeling will be constant and predetermined.
Claim 3
Dependent Claim
38 words
A package as described in claim 1 in which at least a pair of substantially similar disc members are secured superimposed on the end flange, said elongate resilient filaments being sandwiched between said disc members extending radially therefrom.
Claim 4
Dependent Claim
60 words
A package as described in claim 1 which includes: a spring clip; said spool of coiled wire having a bottom flange with a threaded opening therethrough, said spring clip being engaged in the bottom flange; and a threaded fastener is engaged from exterior of the housing into said threaded opening for keeping the spool stationary during unwinding of the wire.
Claim 5
Dependent Claim
19 words
A package as described in claim 1 in which said disc member is removably secured to the end flange.
Claim 6
Dependent Claim
27 words
The combination as set forth in claim 1 wherein the density of filaments per inch length of the periphery of the flange ranges from 5 to 25.
Claim 7
Dependent Claim
21 words
The combination as set forth in claim 1 wherein the length of the filaments ranges from 1 inch to 3 inches.
Claim 8
Dependent Claim
201 words
A package for dispensing wire with preset tension comprising: a. a generally cylindrical housing having an upper wall with a central passageway forming a cover; b. a spool of coiled wire having at least an upper annular flange end, the spool and associated flange end being nonrotatably secured in the housing coaxially therewith and the housing having a wall surrounding the annular flange and spaced therefrom to provide an annular wire confining and unreeling space between the flange and wall, and c. internal wire tensioning means including a ring member nonrotatably secured to the inner wall of the housing and having a plurality of elongate resilient filaments thereon extending radially across said annular spacing impeding the normal unwinding of the wire and adapted to be struck and deflected momentarily by the rotary movement of wire being pulled out of said passageway and passing along the periphery of said flange through said annular space while being unreeled to apply a preset tension value to the wire, the density and size of said filaments being so related to the gauge of wire and the geometric characteristics of the package that the tension of the wire during its unreeling will be constant and predetermined.
