stick temperature are passed over quench roll 2 roll 2 is driven at a given peripheral speed s 1 and maintained at a temperature t r below the average temperature at the center of the filaments the filaments after contacting the surface of roll 2 through a contact angle u03b1 are passed over free rolling roll 3 idler roll then around draw roll 4 and it 39 s associated separator roll 5 with several wraps and finally are packaged by take up device 7 such as by being wound onto a bobbin angle u03b1 must be large enough so that no significant slippage of the filaments occurs on roll 2 conveniently contact angle u03b1 can be changed by moving roll 3 up or down draw roll 4 is driven at a peripheral speed s 2 greater than s 1 and the filaments are drawn as they leave roll 2 the extrusion rate e r distance d temperature t r of roll 2 and s 1 and s 2 and draw ratio dr are correlated to give the desired level of crimp and denier per filament usually roll 2 is maintained at a temperature ranging from 20 u00b0 to about 180 u00b0 c with a range of 30 u00b0 to 100 u00b0 c being particularly useful the roll may be cooled by conventional means such as by cooled air or nitrogen while lower temperatures may be satisfactorily used the cost of refrigeration of the roll renders such temperatures economically unattractive draw ratios usually range from 1 5 1 to 6 1 although not necessary cooling air may be directed if desired onto the filaments between the spinneret.
