Claims
- 1. A method of producing an essentially catenary-free, untwisted, continuous multifilament glass fiber roving, the method comprising the successive steps of:
- (1) withdrawing individual continuous multifilament glass fiber strands from each of a plurality of creel packages;
- (2) assembling them side-by-side to form a single roving of linear density 300 to 10,000 tex;
- (3) passing said roving at a rate of from 150 to 300 meters/minute without positive overfeed, whereby there is no bulking thereof, through a relatively confined air treatment passageway;
- (4) introducing air into said passageway generally normally with respect to the direction of passage of the roving at 0.5 to 1.5 cubic meters/minute under a pessure of from 400 to 600 KN/meter.sup.2, followed by,
- (5) winding the thus treated roving into a package.
- 2. The method of claim 1 including the steps of:
- passing said roving through an open-end V-shaped trough which is in use closed by a lid to define said relatively confined air treatment passageway; and
- introducing air through an aperture in the base of the V located approximately halfway between the ends of the trough.
- 3. The method of claim 1 including the step of:
- the final package winding step providing all the motive power for the withdrawing, assembly and passing said roving through said air treatment passageway steps.
