Apparatus and method are disclosed for spinning filaments from a material such as cellulose acetate dope. The filaments are spun from a spinnerette at the top of a vertically elongated spinning cabinet. Gas is first directed parallel to the filaments as they are spun. A short distance down the cabinet, gas is directed radially inwardly toward the filaments. The two flows of gas merge and flow parallel to the filaments to the bottom of the cabinet, where the gas is withdrawn radially outwardly from the filaments.

Drafting system for textile yarns and including a driven feed roll, a driven output roll, a low friction freely rotatable heated roll located between the driven feed roll and the driven output roll and operating at essentially the same surface speed as the driven feed roll, the freely rotatable heated roll being driven by engagement with the yarn and whereby sufficient yarn tension automatically is transferred upstream of the freely rotatable heated roll to pretension the yarn before it contacts the freely rotatable heated roll with drafting taking place near the location where the yarn leaves the freely rotatable heated roll to pass toward the driven output roll.
