ABSTRACT:
The tension of tow fed to the nip of a pair of differential stretching rollers is controlled by drag rollers. The inertia of the drag rollers limiting their speed of response to tow density changes is compensated for by maintaining the tension at a constant value during periods of speed up and slow down of the drag rollers by utilization of an inertialess means for applying force to the tow between the drag rollers and the differential stretching rollers.
