bins andthe like, with means for removing rovings, yarnsand the like, with the twist substantially intact from bobbiiis orother carriers, of means for reworking thefstilltwisted strippiiigs concurrently with such rey moval of the latter; secondly, in the combination with bobbin-stripping means of novel means for reworking the strippings.

In the case of some stripping machines wthe rovings or yarns as removed from the bobbins or other carriers are periiiit-ted or guided to pass from the stripper-element or elements to the oor below the machine, or tol a convenient receiver. are4 provided with means forgconveying such rovings or yarns to aconvenient place ofdeposit lor receiver located elsewhere. lin-all these cases the strippings are received and accumulated in the form of lengths of more or less intact and still-twisted roviiigs or yarns. For the purpose of being reworked, when reworking is desired, the still-twisted roving's or yarns are taken in. hulk from the said accumulation and carried to a reworking' machine, whichv latter is a second machine, employed for reworking purposes. This procedure involves the transferringof the loose roving's or yarns in bulk from the place of accumulation. to the reworking machine, and the performance of the reworking as a separate operation. By reworking is meant the treatment by which the `iibers of the roviiigs, yarns, etc., lare torn apart so as to resolve the roviiigs, yarns7 or 'the like,

from their more or less twisted condition intoy Other stripping' machines Y An illustrative embodiment of` the invention isshown inthe accompanying drawings,

` Havingreference to the drawiiigs,-A

The 4latter show bobbin-stripping means f organized to vunwind residues of rovings, yarn, or the like from bobbins orpthe like carriers, and to deliverthe substantially intact rovings or the like, as unwound, .into a recep'tacle from which the material isv delivered tothe liber-working elements of the rework-v ing means. 4In this instance the said bobbinstripping means embodies theprinciples of the machine of the United States patent to RichardValwoi-th, No. 1,080,794,j granted 'soA December 9,.,1913 forimprovement in bobbinl stripping machines. As illustrated, it comprises two main strippingr'ollers l, l, (shown` somewhat diagrammatically)V instead of the single main roller-shownat a in the said patent. Atz2,2, Fig. 3, arefsliown auxiliary rollers (also shown somewhat vdiagi'aminatically) cooperating, respectively, with the respective main rollers; thatis to say, there is lrj an auxiliary rollerQl cooperatively associated withone of the main rollersl, and a similar auxiliary roller` cooperatively*associated with the other main roller. lThese auxiliary rollers 2, 2, perform the' same bobbin-retammi;l

and guiding functions that are performed by the auxiliary roller b and guide-bar d ofthe patentaforesaid, wliile-in addition they respectively cooperate with the main rollers v with which they are associated in Vperforming` the function of drawing from the bobbins or Y the like the residuesv of rovingthereoii, as in.

the case of tlieauxiliary roller bof the patent.` Rotation of the individual bobbins asa result of Contact with thel surfacesof the rotva-ting rollers l and 2, accompanied by endi wise travel of the bohbinsflengthwise of ,the rollers 1, 1, 2,2, take-place in thecase of the machine illustrated herein, just as `in the' ease of the m iine shown and),A rib'ed "i the @ugh th'utlisateti at the principles. At 3, 3, Fig. 1, are brushes which make contact with the surfaces of the rollers 1, 1, 2, 2, and serve to remove from such sur-- faces rovings clinging thereto.y y

Below the group of rolls 1, 1, 2, 2, I provide a hopper (indicated somewhat diagram.- matieally) formed by inclined sides l, 4, converging downwardly, and at the bot'tomof the hopper I locate the upper run oi an endless card-clothed7 conveyor-apron 5,. Figs. 1

and 2, extending lengthwise et the rollers and Y veyor-apron, also, a second cardlclothed reworl'ring roll 8f, the teeth of which take :trom

The front wall,.1'5, Figs. 1 and 3, of the casing is, oi' may be, formed with openings 16, 16, inwardly through which air may flow as drawn in bythe tan.

The driving arrangement shown ifn the drawings comprises a round. belt 17' passing partly around greoved pulley 18, Fig. 3', on the shaft of one .of the stripper-rolls 1, ,and Vthen around. a like pulley 19 on 'the shaitvot the other ro4ll1,a guide-pulley 20, and pulleys 21, 22, 23, on the shafts of cardclotliedrolls 7 and' 8 and of the supportingroll 6 oit' thev conveyor-apron. The rolls are or may be driven so that rolls 1, 1", will make 360 P. M'., and that the support-ing roll 6 will revoli'vef at 4.40 R.. l?. M., the card'- clothed roll r"'at 660 R. I): M., andi cardclothed roll 8 at 1000 R. P. M.

y In the operation of the illustrated organi- Zation, the revings unwound by the action of rolls 1, i, 2, 2, drop from the latter to the bottom ofthe hopper, where they are received upon the upper rim ot. the conveyorapron 5. By the movement of the latterthe substantially intact rovi'ngs are lcarried to 'card-clothed roll' 7, the teeth o'whi'ch, preterably dolfer fillet, removes the rovings `from theapron, andatthe same timethe said teeth tear the rovings apart to a greater or less extent by 'reason of the fact that roll 7' has a higher surface speedthan the conveyorapi'on. The teeth of the card-clothed roll 7 carry the partially reworked' rovings around to a point where such material comes within the range ot action of the teeth, preferably straight burnisher iillet,` of'V the card-clothedA roll 8. As roll 8 rotates at a higher surface speedk than roll 7, the rovings are. still further disintegrated. As iast as the said teeth et roll 8 removest'h'e material from vthe teeth oit. roll'?, the material flies off vfrom the teeth ot'rollf 8 into the enclosed space surrounding roll 8. .The material thus thrown into the "said space is carried away by the air-movement due to the suction ot' the V'tan and is blown by the 'fan through the outlet 11t and conduit. lf3 to the desired point.
