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 (34) and take-up rolls (36,38,40) 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 platen (62) contacts the filaments between the godet and take-up rolls to crystalize the drawn filaments. The godet (32) and swing rolls (30) 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.
