ABSTRACT:
Continuous filament tow is partially deregistered, preferably by passing over threaded rolls; and, after being partially deregistered, fully bloomed in an air-blooming mechanism. The air-blooming mechanism draws the partially deregistered tow into a turbulent air flow, maximizing bloom; and then carries the tow after blooming directly into a casing for formation of pillows, cushions, or the like articles. The process is simple and economical.
