Abstract
795,676. Drafting fibres. SKF KUGELLAGERFABRIKEN GES. June 28, 1955 [June 30, 1954], No. 18687/55. Class 120(2) Slivers in which at least half of the fibres are of substantially the same known length are drafted by means of a pair of rollers, one of which has its circumference equal to the fibre length or to a fraction of the fibre length obtained by dividing the length by a whole number. Irregularities in yarn due to periodic displacement of the drafting roller nip caused, e.g. by roller vibration or rollers not being ground true, are said to be prevented by this means. Preferably, one of the top rollers is selected to be of the desired size and the associated bottom roller is of much greater diameter. For worsted yarn fibres; the circumference of the smaller roller will usually be less than 110 m.m. and for staple synthentic fibres or short staple cotton the circumference of the smaller roller will usually be less than 60 m.m. In the embodiment illustrated, a top drafting rolling 35 has its circumference equal to the length or average length of the fibres in the sliver 36. The circumference of the bottom roller 36 is a multiple of the top roller 35 circumference.
