Patented May 13, 1952 vunlTEiii) FEFICIE MACHINE Animat on MW?! 1946, fieriat' il fifiwifi (Shims. (Clara-e127) Tl-he present 'invention refers to improvements in textile machines of the kind comprising-a succession of combs or quillsprovided with -means for freezing and =movi-ng fibre, such -as textile frame machines, drawingor sliver f-rames, ea-rding machines, combing machines, etc.
The main object of-this invention=is to provide machines, of the kindspecified, with -a series: of rods or similar units conveniently --arranged so as to enter between two'or more-rowsoieuills or combs,.thefunction of said rods-being -to re.- move and to move the :fibrc -contained-in .said combs or quills.
A further object of the present invention is to operate the machines such as, for example, drafting or sliver frames-at speeds =-the maxima of which correspond to the=-speed :that can be reached by thedrafting or feeding devices: which are associated with thedrafting or: sliver frames,
thereby obtaining a-consi'denableincrease in output, more than tenefold tha output-oi thecon-v ventional machines.
In order thatthe invention mawbeemoreclearly understood :and' readily carried :into effect, 113136? f erred embodiments of .same, :explicative rebut in no way to. be considered as? limitations: have, been illustrated .in attached drawings, :wherein:
Figure 1 is va diagrammatic :side view of ;a drawing or sliver ,1 frame :of (=3, :textile zinachi-ne,
placed between the ieeding anddnawine.eylin ders and rovidedwitntne imnrnvementsntthis invention, and
Fi ur 2 .is a modifieation-.;of:-the device.zii nstrated in1Figure ;1.
As is known, textile.machinesiforsdnawing;and parallelizing textile fibers ;.compr-ise a;ma,chine provided with inlet .01 fee ing ylinders and drawin 101' delivery cylinders. :the cylinders 111B: ing spaced apartav distance-termed the :pitch or reach, which is related t Ltheflength of :the fibers. Support means are;previdedrfontheefibers between the feeding cylinders and a-the .jdnawing cylinders.
According to the present: invention, thereupport means consists. :of' t-ransversemowsr-of combs or quills and --a plurality of =-ro'ds -interpositioned between a the rows --of combs -"-for--1 emovin-g sfi-bers from the combs. Fibers are iedfrom theiieed ing cylinders onto the support means between the combs or=quills and are carriedfiby the combs up to the drawingcylinders; itnasmuch as -the drawing cylinders .turnat a speediwhiehiis greater than the motion of the--.combs,rtheefibers are-re moved. from :the 100M105? rapidlyaand Slide ealong. the comics: thus bringingzabdutztbeeombin ana allel-ing and drawing step. At this time, .the direction of movement of the combs is changed so that the combs slide along and over :the rods so thattherods remove the fibers from the combs.
As in sl iown in Fig. l, the :textile machine comprises a drawing or i sliver frame, consisting of a pair of endless parallelchains orbelts :i, which support-the ends of transversely disposed combs or quills 2. The belts are positioned-intermediate -t he feed cylinders or -rolls, to:thevright ofthe' belts in Fig. 1,-andthe drawing. cylinders or rolls,-to the left of the belts in ,Fig. 1. The chains-or belts i-move over. guides or guideesections 3, and are -.,actuated:by. chain wheels oricylinders A, i theshaft of :one. of which is connected to --a motor unit, not shown in the drawings.
"Entering between successive .combs or quills 2, are transverse rods 5, which are mountedon another pair of endless chains or belts .1B,.mov-
ingovenproper. guides Land driven bymeans of chain wheels oncylinderseB ,cthe beltsizfi and guides fl are-mountedstothe outside, .orexteriorly, of-;.the belts .and guides 23, so that :the bolts 1 and associatedi quills22 .-may, pass between the; belts i5 andrgnides' 'l.
:Asshown inzFig; '1, anothergroup of. transverse rods; 91-may:be.arranged above thisassembly. said rods being suppprtedwith ;.their, ends :bya pair of endless .chai-nsor belts 1| 0 ,passingovenfiQII? spending. chain-.wh.ee1s;.orv cylinders H flxhe :IQCIS .59 I enter ibetween the combs pr; quills '2 :on the upper stretch .of the. endless. chain; or belt: l,..and exert pressure on .thBsfiblOllS material fed-jntosthe machine. .sogthatthe. quills or. combs 2 are; forced into :the material.
iWhen the .moving parts of .the :described has.- sembly'. are inimotion; inzthe direction. indicated byiarrows: in Figure. 1,: it.-willv :benoted that,.at..the rearend ofzthe machine the pair of endless chains ori-belts .6 do notdescend =at the same-time with the endless chains or. belts I, but that the-former move: horimntally along agreater stretch: before movin downwardly.
"LI'he oba'ect of .this :is to allow thecombs or rows .of :quiills 2, --to bear i during their downward movement along this differential stretch of theirsjourney, .against: the :rods i5, and= to: slide on same, -.as aiconsequence -.of which' said rods -r-emove I and .transport the fibrous' material situated in said combs or quills-.2.
Fig. 2 illustrates .a modification of i the above describedi-machmeof the. invention.
rIILEig.:2,;tWQ pairs ofiendless chains and combs andi redssof construction .similar to 1 that-shown ijlyhaveg-beensuperposed, analogous parts 3 of the two units being identified with the same reference numbers.
The pairs of endless chains or belts 2| supporting combs or quills 22 are trained over rotatable chain wheels or cylinders 24 and stationary guides 23, the two units being positioned between the feed cylinders, to the right, and the drawing cylinders, to the left. The pairs of endless chains or belts 26 carrying transverse rods are trained over chain wheels or cylinders 28 and stationary guides 21, the arrangement being such that the rods 25 enter into the row of horizontally moving combs 22 of the associated comb assembly. The guides 21 extend a short distance beyond the run off end of the endless chains or belts 2| to properly guide the rods 25 downwardly and out of engagement with the combs 22.
A comparison of the two units'will show that they are identical, the upper unit being inverted and the comb assemblies of the two units combining in the drawing or slivering action. Each unit of the total assembly is very similar to the unit disclosed in Fig. l. The two pairs of end- .less chains or belts 2| in the assembly shown in Fig. 2 are so arranged that the upper and lower horizontal portions which are parallel to each other and move in the same direction are so closely adjacent each other that the combs 22 on the lower belts 2| enter into the spaces formed between the comb 22 on the upper belts 2|.
The improvement disclosed by this invention can be adapted by a great number of textile machines; therefore, that which has been illustrated and described should only be taken as an example, which is capable of being modified in construction and detail without departing from the scope of the invention and the appended claims.
