Abstract
Abstract Wire coming hot from a rolling mill traverses an eccentric duct in a rotating body and emerges therefrom at the periphery of a frustoconical disk which is centered on the axis of rotation and is held stationary by a planetary-gear system. A tapering guide roller, journaled on the body adjacent the outlet of the duct, helps wind the emerging wire about the disk periphery from which the wire loops slide off axially, the roller axis being oriented skew to the axis of rotation to impart an axial component to the motion of the wire exiting from the rotating body.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A wire-looping apparatus comprising: a stationary support; a body journaled on said support for rotation about a central axis, said body being provided with a curved duct having an entrance end on said axis and an axially oriented exit end remote from said axis; an outwardly tapering stationary disk adjacent said body centered on said axis, said disk having a peripheral edge close to the orbit of said exit end about said axis; and an outwardly tapering guide roller mounted on said body adjacent said exit end outside said disk for winding an emerging length of wire, fed into said duct at said eNtrance end, about the periphery of said disk in successive turns sliding axially off said periphery, said exit end opening into a gap between said roller and said disk.
Claim 2
Dependent Claim
132 words
A wire-looping apparatus comprising: a stationary support; a body journaled on said support for rotation about a central axis, said body being provided with a curved duct having an entrance end on said axis and an axially oriented exit end remote from said axis; an outwardly tapering stationary disk adjacent said body centered on said axis, said disk having a peripheral edge close to the orbit of said exit end about said axis; and an outwardly tapering guide roller mounted on said body adjacent said exit end outside said disk for winding an emerging length of wire, fed into said duct at said eNtrance end, about the periphery of said disk in successive turns sliding axially off said periphery, said exit end opening into a gap between said roller and said disk.
Claim 3
Dependent Claim
38 words
An apparatus as defined in claim 1 wherein said roller has an axis lying skew to said central axis at an angle imparting an axial component of motion, away from said body, to the emerging length of wire.
Claim 4
Dependent Claim
19 words
An apparatus as defined in claim 1, further comprising transport means for said length of wire on said disk.
Claim 5
Dependent Claim
34 words
An apparatus as defined in claim 3 wherein said transport means comprises a vibrator, further comprising an energizing circuit for said vibrator including a pair of sliding contacts on said body and said disk.
Claim 6
Dependent Claim
26 words
An apparatus as defined in claim 1, further comprising a planetary-gear train linking said disk with said support through said body for holding said disk stationary.
Claim 7
Dependent Claim
41 words
An apparatus as defined in claim 5 whrein said planetary-gear train comprises a pair of equisized sun gears on said support and said disk and a pair of equisized interconnected planet gears on said body respectively meshing with said sun gears.
Claim 8
Dependent Claim
140 words
A wire-looping apparatus comprising: a stationary support; a body journaled on said support for rotation about a central axis, said body being provided with a curved duct having an entrance end on said axis and an exit end remote from said axis; a stationary disk adjacent said body centered on said axis, said disk having a peripheral edge close to the orbit of said exit end about said axis; a guide member mounted on said body adjacent said exit end outside said disk for winding an emerging length of wire, fed into said duct at said entrance end, about the periphery of said disk in successive turns sliding axially off said periphery; a vibrator for advancing said turns along said periphery; and an energizing circuit for said vibrator including a pair of sliding contacts on said body and said disk.
Claim 9
Dependent Claim
140 words
A wire-looping apparatus comprising: a stationary support; a body journaled on said support for rotation about a central axis, said body being provided with a curved duct having an entrance end on said axis and an exit end remote from said axis; a stationary disk adjacent said body centered on said axis, said disk having a peripheral edge close to the orbit of said exit end about said axis; a guide member mounted on said body adjacent said exit end outside said disk for winding an emerging length of wire, fed into said duct at said entrance end, about the periphery of said disk in successive turns sliding axially off said periphery; a vibrator for advancing said turns along said periphery; and an energizing circuit for said vibrator including a pair of sliding contacts on said body and said disk.
