Abstract
Abstract Apparatus for applying a wire coil to a fine wire strand, in which the fine strand to be wound is drawn through the axis of a rotatable hollow shaft which is arranged coaxially with the supply reel for the coiling wire, this supply reel being mounted within an open ended pot receptacle joined to the shaft and rotating therewith, wire guiding and braking means preferably in the form of radially extending disks or rings being inserted in the path of the coiling wire as it is drawn from the supply reel over the guide and brake means to a winding point adjacent the front or exit end of the hollow shaft.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
170 words
Apparatus for applying a wire coil to a fine wire strand which comprises: a rotatable hollow shaft adapted to receive The fine wire strand being wound in combination with means for drawing said strand axially through said shaft; a rotationally symmetrical pot receptacle joined securely to said shaft for rotation therewith and being open toward the wire exit end of said shaft which projects axially outwardly from said pot receptacle; a supply reel for the coiling wire seated in a fixed position on said shaft concentrically within said pot receptacle; and wire guiding and braking means positioned along the axis of said shaft between said supply reel and the axially exposed exit end of said shaft including at least two annular run-over rings together with at least one disk brake means which interacts with the opposing inner peripheral wall surface of said pot receptacle to apply a resilient braking pressure to said coiling wire being drawn from said reel to a winding-on point adjacent the exit end of said shaft.
Claim 2
Dependent Claim
170 words
Apparatus for applying a wire coil to a fine wire strand which comprises: a rotatable hollow shaft adapted to receive The fine wire strand being wound in combination with means for drawing said strand axially through said shaft; a rotationally symmetrical pot receptacle joined securely to said shaft for rotation therewith and being open toward the wire exit end of said shaft which projects axially outwardly from said pot receptacle; a supply reel for the coiling wire seated in a fixed position on said shaft concentrically within said pot receptacle; and wire guiding and braking means positioned along the axis of said shaft between said supply reel and the axially exposed exit end of said shaft including at least two annular run-over rings together with at least one disk brake means which interacts with the opposing inner peripheral wall surface of said pot receptacle to apply a resilient braking pressure to said coiling wire being drawn from said reel to a winding-on point adjacent the exit end of said shaft.
Claim 3
Dependent Claim
41 words
Apparatus as claimed in claim 1 wherein said pot receptacle is substantially cylindrical over its axial length adjacent its closed end corresponding to the enclosed axial length of said supply reel and then widens conically outwardly to its opposite open end.
Claim 4
Dependent Claim
28 words
Apparatus as claimed in claim 2 wherein the total axial length of said pot receptacle is about 1.5 to 2.2 times the axial length of the supply reel.
Claim 5
Dependent Claim
21 words
Apparatus as claimed in claim 2 wherein said braking means are adjustably insertable on said hollow shaft through interchangeable spacing members.
Claim 6
Dependent Claim
30 words
Apparatus as claimed in claim 1 wherein said supply reel is removably insertable over the exit end of the shaft and is fastened within said pot receptacle by clamping means.
Claim 7
Dependent Claim
59 words
Apparatus as claimed in claim 5 wherein said clamping means include a tightening nut threaded onto the exit end of said hollow shaft to engage and clamp said supply reel between said wire guiding and braking means on one side of said reel and the closed base end of said pot receptacle on the other side of said reel.
Claim 8
Dependent Claim
25 words
Apparatus as claimed in claim 6 wherein individual braking disks are clamped between run-over rings arranged on either side thereof along the hollow shaft axis.
Claim 9
Dependent Claim
26 words
Apparatus as claimed in claim 1 wherein a brake disk cooperating with the wall of the pot receptacle is composed of a resilient, wearproof plastic material.
Claim 10
Dependent Claim
17 words
Apparatus as claimed in claim 8 wherein said brake disk is composed of a plasticized polyvinyl chloride.
Claim 11
Dependent Claim
44 words
Apparatus as claimed in claim 1 wherein a brake disk cooperating with the wall of the pot receptacle includes a large number of bristles arranged densely next to one another in a plurality of layers projecting radially from the outer edge of the disk.
Claim 12
Dependent Claim
14 words
Apparatus as claimed in claim 10 wherein said bristles are fibrous, stiff animal bristles.
Claim 13
Dependent Claim
14 words
Apparatus as claimed in claim 10 wherein said bristles are fibrous, stiff polyamide bristles.
Claim 14
Dependent Claim
12 words
Apparatus as claimed in claim 10 wherein said bristles are steel bristles.
Claim 15
Dependent Claim
21 words
Apparatus as claimed in claim 1 wherein said braking means are adjustably insertable on said hollow shaft through interchangeable spacing members.
Claim 16
Dependent Claim
42 words
Apparatus as claimed in claim 1 wherein said hollow shaft is conically narrowed at its exit end where it also contains at least one axial insert narrowing the size of the hollow bore through which the fine wire strand is axially drawn.
Claim 17
Dependent Claim
38 words
Apparatus as claimed in claim 1 wherein coiling wire is wound on the supply reel such that the ratio of the diameter of the full reel to that of the empty reel is not substantially greater than 5:4.
