.JIhe invention relates to finisher;cards, also called condenser cards, which are followed at their outlet. by a; special apparatus called fweb divider or condenser, the purpose of which is tosplit ,up' the web delivered by. the doffer into arseries of strips or ribbons of equal widths, aid strips-of web thenbeing rounded into the shape of-ropings, condenser yarns or slivers, in order} to make them stronger, by passing them between rubber gears or rubbing aprons, said slivers or ropings being finally cross-wound on spools so as'jto form condenser bobbins or jack spools to facilitate the conveyance thereof to'the spinning frames, w I

-;,;It is known, that these condenser bobbins are driven by friction by operated drawing or at-. tracting roller and that the crossw'inding. of the slivers. isobtained either by imparting to these traction rollers or tractonand to-th'e condenserbobbins, in addition to their rotary-movement, an; axial reciprocating movement, while the I111 Claims. (cue -.153) I v y; are wooden" spools.

sliver- -guides which precede them and which receive the slivers at the outlet of the rubbersremain stationary, or by imparting'to said sliver-' guides a-reciprocating movement, while theftrac tion-rollers and thecondenser-bobbins only, effect alrotary movement. v

It is also known that to each bank, and thereforeto-the outlet of .each pair of rubbers, there corresponds such 'a ,system comprising sliver -guide s -,;ja spool and, a tractor that; draws theropingsin a continuous manner, 'said'system being supported at its ends .betweenthefront, JIDfY rights of; the: lateral names, or i side-plates of the machine, the length of each fsyst corresponding to the width tjfsa I, the vertically combined syste so whc heightthewinding apparatusfl I i, r

This type of winding apparatus has the draw back, in particular, of being unable"tog ive to the cheeses widths and diameters which ar'evar-' iable according vto the, reduirementofithe' spinning frames, the reason being the" necessarily re"-' stricted-length of the spools and also their-spac-j ing-yvhich is also restricted in height on" the front facesof the condenser, thediame'ter of the lack spools being furthermorelimited bythe'requirements of visibility andaccesstofthe tapes and to the, rubbing aprons; v

In view of the fact thatin ordert'o overcome the above explained drawbacks, 'itappearsto be' practically impossible tolmcr'ease the areaof the front face of the dividing'fapparatus' or. 'c n? denser, the invention has foriits objectto .pro-I vide a new type ofwindihg apparfatuslforfcon denser cards, whereby itbecomeshenceforthpos= sibleto obtain interalia andin particular: 5 a

v A largernumber of systems, comprising a sliver-guide, av traction roller and a spool, than the;number ofbanks of the-,condenser, thereby enabling the ropingsof a banktolbe distributed oyer one, twojo'r' a largernumber of systems.

5 b) Lengths of spools which areivariable and greater than the width'of the. front face of the condenser, and also vertical's'pac'ings between'the' systems, which are greater than the yerticalspajcings between thebanks', thereby'making it pos-' sible to give to the cheeses'widths' and diameters which are variable according to. therequirem'ent 0f thespinning frames. I 1

(c) A greater facility for removing the full jack spoolsand also for automatically replacing them llaving explainedthisfthe novel type of wind ing apparatus accordin'g'to the invention is'char acterized, in principle, in'that the system's, comprising a, ropings or slivers-guide, a tractor and a spool, are independent of the dividing, appara-. tus. and 'are located apart in front of the face of said apparatus, and in that, in combination with such systems thus located, means/areprovided fordirectly picking-up .the ropings' as' they come out'of' the rubbing'a'prons'and conveyingthein to the systemsand directly delivering the the tractors"of said'systenis'ff'f', f This novel type of ',1wind'i 'g" apparatusfis fur thermore character ze according ,to' the invention, by" the renewing points, taken, separately or inf anycombinationsif a) ..The systems" are. mounted on stationary or movable racks located in front of thefface and onieither side of the. condenser, it being possible for. the height. and the width of, said-racks: to be greaterj than the height and t e width. or the front face of the, dividing apparatus, and said. fracks lmay ,beari'anged, either parallel'ito the" medial vertical plane of the dividingima-j chine, or angularly with respect tojsaid plane; Kb) 'l'the'numbe'r- LQf. systems mounted on the racks isat least equal to the numbenof banks, their length and their vertical spacing'being at least equal tothe' width and to the height of'the front face of the condenser.

ropingS guides; being effected either by the'usual veying tubes of each bundle to be lengthened or shortened according to requirements, and also for enabling them, at certain points of their path, to be shifted for adjusting their lengths movements of the racks and. also the recipro-gx.

cating movements of the ropings-guides.

In order to enable the invention to be. more clearly understood and also by way of ei'nbodi ments thereof, means are described hereinafter and diagrammatically illustrated in the accompanying drawings,- for enabling a winding apparatus' of the novel type according to-theinvention to be constructed, said winding apparatus being in the present case'- provided with pivotally mounted racks and being adapted to convey the ropings pneumatically.

Onthe samepivot Gare mounted in the vertical direction, for each system, crank-plates 1! pro-- vided with a crank-pin 20 that controls theos cillation of a. cranked lever-21 42 providedwith a slideway, said lever being pivoted at 23, and the arm 22 of which actuates', by means of its slideway; a pini 2K fixed. 'atjthe' end of the bar 8-tliat replacesthe ropings -guide.

Likewise'by means of this arrangement; the reciprocating movementof' the bars 8 takes place regularly, irrespective of the angle 1 of opening of theracks' h J 7 ,In order to'effect'the' conveyance of the ropings, whichare 'fra'gileowing to the fact that they" have only received a slight compression and have not yet beensubjected" to any twisting, the racksand the systems are provided, in combination, with suitable conveying means for picking upth'e' ropings at theactual outlet of the rubbing aprons, conveying them to the racks-and delivering them to the .traction rollers of the respective systems: to which'theypertaim1 In the ,embodimentwhi'ch; it" given by wayof examples, the conveyance of said ropings is'ef-r fected pneumatically; and; the pneumaticdevice provided for thispurposeihas, inter aliaand in particulazithe followingifeaturesr "For each bank; each of the ropi'ngs; at the out-- let of the rubbers, is sucked intoone of the-tubes of one or more bundles of tubes which then con-. vey them by blowing. to the systems whichcorrespond to each of the banks and which are varranged on the racks located on either side in front of the face of the condenser, each .roping which is blown as it comes out of its'tube, feeding the tractor of the system to which .it is intended.

Each tube of the bundles is provided, near its inlet opening .for the ropings, with a sucking and blowing device or head.

Each bundle of tubes ends to its respective creel, opposite the system which it has'to feed.

In order to enable the bundles of tubes to. follow. the movements of the pivoting racks, each tube is articulated at a suitable point of its path, and similarly, in order to permit the variations of lengths due to the angular movement of said racks and in order to permit the variable adjustment of the mutual spacing between the outlet ends of the tubes, according to the width to be given to the cheeses on the spools, each tube, in the portion thereof that pertains to the rack, is provided for this purpose with a sliding section which enables it tobe lengthened or shortened.

' In addition, in order to enable the outlet ends of the tubes, oroutlet tubes, that openonto the tractors, to follow the, reciprocating movement of the bar which supports them and which replaces theropings-guides, each of said outlet tubes is articulated. I

- According to the figures that relate more particularly to the pneumatic conveying device (in particular Fig. 9 that illustrates diagrammatically a bundle of tubessupplying a system), are the tubes whose inlet ends are provided with spouts 26 for sucking the ropings 21 as they issue from the rubbers 2.

28 are joints that enable the tubes to pivot .according tothe positions given to the racks, 29 joints for the sliding of the tube sections so that they can follow the movements of the racks and so that the adjustment of the spacing can be cf,- fected according to the width to be given to the cheeses, and 30 are joints for the articulation of the outlet tubes 25, said joints being provided with a rubber sleeve 3| (Fig. 19) that ensures the fluid-tightness of the joint.

For the suction and the blowing of the ropings 21, each of the inlet ends of thetubes 25 of the bundle of tubes is provided with a sucking and blowing device or head 32 of any type (Fig. 11) connected to a compressed air distributing system33. v

For the reciprocating movement of the outlet tubes 25 which are articulatedat 30, the same rest in supports 34 fixed on the bar 8 that replaces the usual ropings-guides. Said supports 34 can be mounted at will along the bar 8 by engaging them in holes 35, a suitable number of which are provided on said bar, thereby enabling the spacing between said outlet tubes to be adjusted according to the width to be given to the cheeses, said spacing being made possible by the slidable mounting of the tubes 25, the joints 29 of which are fixed on a plate 36 of the racks 4, opposite the tractor 9 of each system.

In order to retain the position of the tubes on the plate 36 after their length has been adjusted, and also to enable this adjustment to be effected, the tubes are held in position by tubefasteners 31 provided with pivotally mounted latches 38 which have a heel 39 adapted, by merely rocking. to engage in or .be disengaged from stop notches 40 Provided at suitable intervals along the upper edge of said Plate 36.

Finally, the feed of the systems with ropings 21 6. is greatly facilitated bythe .cha'nnel shapev 25 given to the ends of the outlet tubes 25 (Fig. 20). When the machine is started, the ends of the ropings 21, which are pneumatically conveyed from the rubbers 2 through the tubes 25 and are blown out of theoutlet tubes 25*, are projected into contact with the traction rollers or tractors 9,: and gripped between said tractors and the spools I0 onto which each of them is wound with a crossed winding, to form a cheese (Fig. 16).

When a jack spool 10 is full. an empty spool 10 is placed so as to rest against the tractor 9, and bear against the channels 25*, so that after the ropings have beenbroken and said jack spool I (I removed, without its being necessary to engage each roping byhand,'said ropings are automatically caught up by blowing and carried between the tractor 9 and said empty spool Ill. which then takes the place of the jack spool III which has been removed (Figs. 17 and 18) thereby making it possible not tohave to stop the dividing machine. It is of course to be understood thatv without exceeding the scope ofthe invention, improvements, modifications or additions can be made, and also the ,use of equivalent means may be contemplated.

Thus ,for example, the suction and blowing head 32 may be replaced by a sucking and blowing device which is located at the inlet of a bundle of tubes and is combined with an additional blowing device which may be made necessary for causing the ropings to pass through the bent parts of the tubes during their conveyance through the tubes of said bundle. 1

According to this modification (Fig. 21), a blower 4i suppliedby, a distribution pipe 42 is provided with a nozzle 43- mounted at the end of an elastic joint .44, which enables the nozzle to be inserted into one of the roping conveying tubes 25,, at, will, in the case in which an additional blowing pressure is necessary, while the P113833 supplies a blowing andsucking device 45 also provided with a nozzle 46 mounted at the tem having rubbing aprons to provide ropings, in
