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
72 words
In an apparatus for the production of a solid metal filament from a molten source using a quenching wheel as a quenching element, the improvement which comprises a pressure exerting means for pressing the metal filament against the quenching wheel at a point just beyond the point of solidification of the filament on the quenching wheel, thereby creating a tension-free zone and inhibiting premature detachment of the filament from the quenching wheel.
Claim 2
Dependent Claim
72 words

Claim 3
Dependent Claim
15 words
The apparatus of claim 1 wherein the pressure exerting means is a cold nipping wheel.
Claim 4
Dependent Claim
22 words
The apparatus of claim 2 wherein the nipping wheel rotates on an axis substantially parallel to the axis of the quenching wheel.
Claim 5
Dependent Claim
12 words
The apparatus of claim 1 which includes a tension regulating collecting device.
