Abstract
Abstract A method for producing and concomitantly winding continuous metal filament in which a quenching wheel is used as a quenching element and in which sufficient pressure is exerted on the filament just beyond the point of solidification to counteract the tensional stress exhibited by the winder on the filament.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
78 words
In a method for the production of metal filaments from a molten source using a rotating quenching wheel as a quenching element, the improvement which comprises exerting sufficient nipping pressure on the formed filament at a point on the quenching wheel beyond the point of solificiation of the filament and prior to the point said filament is separated from the quenching wheel by centrifugal action to retain the filament against the quenching wheel and subsequently collecting the filament.
Claim 2
Dependent Claim
78 words
In a method for the production of metal filaments from a molten source using a rotating quenching wheel as a quenching element, the improvement which comprises exerting sufficient nipping pressure on the formed filament at a point on the quenching wheel beyond the point of solificiation of the filament and prior to the point said filament is separated from the quenching wheel by centrifugal action to retain the filament against the quenching wheel and subsequently collecting the filament.
Claim 3
Dependent Claim
55 words
The method of claim 1 wherein the formed filament is directed onto a tension regulated winding device and the nipping pressure exerted is sufficient to counteract the tensional stress exhibited on the filament by the winder and to create a tension free zone in which continuous lengths of filament can be produced and concomitantly wound.
Claim 4
Dependent Claim
63 words
The method of claim 2 wherein the nipping pressure in lbs/inch exerted is at Least as great as that derived from the equation: T/ Mu QR + Mu NR where T is the winding tension in lbs/inch of filament width and Mu QR and Mu NR are coefficients of friction between the filament and quenching wheel and the filament and nip roller respectively.
Claim 5
Dependent Claim
16 words
The method of claim 1 wherein the nipping pressure is exerted by a cold nipping wheel.
