ABSTRACT:
Filament processing apparatus embodying the combination of one or more rotatable rollers for conveying a filament or a plurality of filaments axially spaced on said roller(s) and looped at least partially about the respective roller surfaces, and a tubular roller-threading device which is a longitudinally slotted tube having at least a curvate portion adjacent the respective roller(s). The filament, preferably either knotted at its feed end or attached to a plug at its feed end, is drawn through the tubular roller-threading device by a fluid stream applied at a single or axially spaced points into the tube. The longitudinal slot of the tube allows the fluid-conveyed filament to be drawn out of the tube when the filament is placed in tension, e.g., after it has been fed around the respective rollers, and processing thereof is ready to begin.
