WALTER DRAPEI'LOF oHoRLEY, ENGLAND DRAW'ING on DRAFTING ROLLER r03 TEXTILEQSPINNING MACHINERY; k
Application filed August 27, 1829, Serial No. 388,703,.and in Great Britain Februaryfl, 1929. 5
This invention has reference to textile spinning machinery and particularly to machinery used in the spinning oi: fibrous materials, here drawing or drafting takes place,
5 examples of such nachines as used in cot-ton spinning being those knownas derbys, ribbon lap machines, combers, draw, slubbing, intermediate, roving or jack andring frames, and mules.
' The object of drawing or drafting is'to straighten and align the fibresof the material such as cotton sliver or roving, and tocause ij them toslide over one anotheigthuselongat- 'ing and attenuating the ShVGIZ The ultimate mm of all'spinning operations is to produce a yarn Which is strongand un1 for1n. Inthe, course 015- manufacture the sliver-passes through'a number of consecutive processes beforeit becomes the flinished 'yarmand in i i i 1y controlled by both rollers and the front many of these draftingis'a feature, is therefore of'the utmost importance thatdrawa Way as to yield aunii'orm material, Without Weak or thin places an'd'also that'the process employed should be capable of yielding a satisfactory yarn. r 4
I have established that if both top and bottom rollers in the line immediately behind a the delivery or front rollersare made plain and smooth of polished metal and the Weight of the top roller alsohavi-ng these characteristics is proportioned so as to hold the sliver firmly between the two rollers Without any nip, a remarkable improvement takes place in the drafting results when a lines of rollers are fluted.
According to my invention as applied to' a three line system, I use forthe back and front rollers the usual rollers i. e. a fluted- I employ an unfluted bottom roller of smooth and polished metal in conjunction with an unfluted top roller having the same characterand strong the other bottom front or of rollers and B andB and C.
