ABSTRACT:
A novel spinneret orifice defines in the plane of a spinneret face an elongated slot formed by a series of repeating parallelograms connected in end-to-end relation together and alternating in off-set relation along the major axis of the elongated slot, each parallelogram having a pair of opposite side walls "a" substantially parallel to the minor axis of the elongated slot and a pair of opposite side walls "b" substantially parallel to the major axis, and wherein a side wall "a" of one parallelogram and the side wall "a" of the adjacent off-set parallelogram lie on a common line and define the angle of the minor axis relative to the major axis of the elongated slot.
