摘要： Apparatus for cleaning surface lint and debris from a plurality of traveling textile warp yarns includes a slotted reed mounted on a vacuum housing with each reed slot opening into the housing interior. A blower is disposed within the housing to apply suction to the yarns traveling through the reed slots and a filter is interposed between the reed and the blower to separate lint and debris removed from the yarn. A cover is movable into and out of covering relation to the reed to constrain ambient air to be drawn into the housing from the opposite sides of the reed generally in alignment with the direction of yarn travel to prevent the suction force from imposing additional tension on the yarns and to minimize entrance of air borne ambient lint into the vacuum housing.

摘要： A drawing apparatus for a textile draw warping system includes rotatable feed, swing, godet and take-up rolls about which a plurality of synthetic continuous filaments travel in sequential peripheral engagement. The godet and take-up rolls are driven at different relative speeds with the godet roll being heated above the glass transition temperature of the filaments to cause drawing of the filaments between the godet and take-up rolls. A heated contacts the filaments between the godet and take-up rolls to crystalize the drawn filaments. The godet and swing rolls are mounted for movement in respective arcuate paths which are mutually convex to one another for disengaging the filaments from the godet roll upon stoppage of the drawing system while maintaining constant filament tension to prevent overheating and degradation of the filaments. The platen is also movable away from the filament path upon system stoppages in coordinated relation to the decreasing speed of filament travel.
