Abstract
Abstract A process and apparatus is disclosed for the production of untwisted, continuous lengths of metal filaments from a molten stream by casting the molten stream onto the inside surface of an annular chill roll wherein the inside surface is inclined at an angle of 2*-30* to the axis of rotation of the chill roll, exerting pressure on the quenched molten stream in contact with the inside surface of the chill roll after solidification and collecting the filament thus formed.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
108 words
A process for the production of continuous length untwisted metal filaments from a molten stream comprising the steps of: a. casting the molten stream on the inside surface of a rotating annular chill roll wherein the inside surface is inclined at an angle of 2*-30* to the axis of rotation of the chill roll; b. after solidification of the filament exerting pressure on the quenched molten stream in contact with the inside surface of the chill roll; to increase retention of the filament in contact with the quenching surface by nipping means applied on the inside surface of the chill roll; and c. collecting the filament thus formed.
Claim 2
Dependent Claim
108 words
A process for the production of continuous length untwisted metal filaments from a molten stream comprising the steps of: a. casting the molten stream on the inside surface of a rotating annular chill roll wherein the inside surface is inclined at an angle of 2*-30* to the axis of rotation of the chill roll; b. after solidification of the filament exerting pressure on the quenched molten stream in contact with the inside surface of the chill roll; to increase retention of the filament in contact with the quenching surface by nipping means applied on the inside surface of the chill roll; and c. collecting the filament thus formed.
Claim 3
Dependent Claim
37 words
The method of claim 1 wherein the filament after solidification is oriented to remove twist by guide means whose axis is skewed to the axis of the nipping means and thereby direct the untwisted filament for collection.
