Controlled tow stretching process |
摘要 |
This is an improved apparatus and process for stretching a tow of filaments by the tension caused by driven rolls dragging the tow across drag rolls. The improvement comprises continuously controlling at least one undriven or drag roll proportional to the sensed variation in a ratio of speed between at least one driven roll and at least one drag roll.
