A first flange is detachably connected to the first end of the wind-:feg cote, a second fiange Is rightly fisod: to fee second md offen wording care. The fefeasabie connection between the first flange and fee first end of the winding cote is realised In this winding spool by segment letches provided on the fess fiange, tfeieh enpp fe Ootrespondfeg lateh openings trrovided os fee first end offen winding core. In addition, at fee fist end of fee winding core a so called ail around latch directed inwardly towards the rods: of roMron is provided which is mfeasably m engagement wife an oppositely directed aft sfeond hitch on fee flange. With: fee afl-arotmd latch, a locking system is implemented, which is: similar in its ikncdoning to fee well-known clostites fer pshft backets. The whaling spool realised la ft-is fertn-fittfeg cooaeetion between the winding core and removable flange is here1 coaflgared allogefeer to such a way that both, assesnbly and disassembly of fee ithlgs by hasd, Is possible.

This object Is achieved by the spool and fee spool component system, respectively, according to fee independent claims.

According to the invention,: several second latch portions are provided on fee: first end of fen spool bore and several second latch elements are provided at fee first fiangei wherein the second latch portions fee arranged: on: fee spool: core in sock a manner and fee second: latch elfenontS: are arranged on thelÄbftspge and/or designed lb such a manner shat the attentai latching elOOrants of fee fifesge engage with fee eorrespbhding second latch fpo lions of fee spool core, when: first hitch elements provided m the first flange engage wife eotrosponrifeg: first latch podfens provided on fee first end of fee spool core, whereby a fenn-ilttiug connection between the first flange: and the spoof core Is pfedaced.

For fixing fee first fiangs: at fee first eori: of the spool core, the same is mounted on fee first esd Of tbs-spool coffe aod - if ibe angular position ρί fee first and second latch elements is not the same with respect: to fee angular position Of fee respective: first; and second latch portions - Is rotated relative to the spool core ontil fee angular position coincides, the angular psifioa feghÉhi*. fife first liUching elements of Ée f&st ffege esti engage wife the ceriespoading iírSt latch péti fees of life: Spool fess,; fele!« its second latehmg: «fetaeats of feg first íasttge can be brought: shnölíanoppsty Safe engagement i«Ä fee seeondiafeh prions. of the: spool core, by pressing the first flange in fee axial direction, preteMy manually, ostfe the spool cere, Hereby, relatively «»ail inees are sfelejent.

However, as engagement of fee -fest and feeond latch portions and lattá sfetpeots does not necessarily require a mntaai rotation of fee spool core sód the Hamely, if the first flange; Is applied in feo rigbt position in fee drcumferenial direction, Le, angular position the first and second latch feehfehts of the first fiange can en-gage simply by axial sliding of the first flange on fee conical spool core in fee respective first and second latch portions on fee spool core.

By the Invention, It is achieved: feat in addition to fixing fee first flange at fee first end of fee spool com by means of a plurality of coaplcs of first latch element-latch porion, an additional fixing by means of aplurality of second couples of latch element-Mch pcriifih which are different hoot fire fs£t Spngfe b? felfe ÄansNateh portion occurs.

By fee second couples of latch eiemestdafeh portion provided by fee present fevefeipn, fee first Äftgft feby be seepred to fee spool cote in a simple manner In addition againk twisting. Thereby,, a more feiiable fixtfetfe of fee fiahp at fee spool core is reached with a femplffed design.

In a first variant* fee spool is a eost-eifieient, disposable and smgle-use spool, Le, designed fer a untqae winding with winding material add its unique withdrawal. For reasons: of eost-effecriveacss, fee »all thickness of the spool core in this ease is relatively fein nod typically | fe | pm, preferably feront 1,5 msn

Wife these dfesensitms, 11 may hé nééçréfey feat fee Ägferese »pool ip!f IbS fe be carried during the wfedhtg process fey an appropriately difeansioned, la pfeticular also conleai riapdard spool, since this is fee only manner feat fee single-use spool is able to lake fee Winding ferees and that fife tepque ofthe propukion of fire: winder «an be transmitted via the standard single spool to the aiaglemse spoof Tb« toppe is thereby transodfeed through factionandfer Ifenn-fit from the standard spool to the single-ose sprefi.

The first and second latch elements and latch portions can, in this case, 1¾ ada^fegebosîy pfeifiptred so feat a disengagement of fee first flange from the spool com is no longer possible without an additional device or a suitable special tool, so that, after use, the spool cannot he readily disassembled, such as by manual operation of a pull tab as tbc winding spool known from WO 20fi5/0?(iS02 AÎ. The latch elements or latch pottions can be deliberately desigaed in a way to prevent any misuse oftfife spool of fife invmaiba preferably designed m a single-use spool as separable and possibly reusable spool, fe this way, a simple, especially manual, disassembling fifths spool for a spp-saymg: return transport of fife tpfei after refeoyafbfi fife wfedfei fe a new winding with winding material can be prevented. fe a second variant, the spool is designed as a reusable spool which is, after a winding sod removal of winding material, available fer at feast another winding and retaotfel of winding; material. Mere, in strife fe easnfe a suffe efentiy high mechanical stability and wear resistance of the spool, the spohf core has a wall thickness of typically 2 fe 5 nuts, its particular about 3 mm. Alternatively or in addition, by selecting a suitable material with a higher strength - as ifetbpared with fife material used ihr the spool core of a disposable spool - a hiper mechanical: stability of foe spoof core can bo achieved, A. söpört of foe reusable spool; fey a Anther spool, as may fee; provided at; a; single-use spoof, is hereby usmdly sot: necessary?, feat In principle possible when, fee example parttelarfy high winding force» ocenr or pntfenlarfy fdgfe torpue fern foe winder of the winding device hove to be transferred to tbs rensshle spool,

Is this variant of the sped,· It is advantageous when, after the removal: of the winding material* foe first flange is removed from tbs first end: rtf the spool core. Conical spool cores, which have only a second Hange at a second end with a larger diameter* cm be poshed Into each Other and stacked in a space-saving manner. With slaefeed spool cores, first flanges which are preferably also designed stackable can he transported separately to a winding station whore the first flanges are then fixed, preferably just before the winding process, again at the first end of the spool core, in this variant, foe; fpt and second iafoh elements; and latch portions .may advantageously be designed so that a simple manual and ?foo#í$döetiw dloasseofoly of foe first flange feom the spool core without -art additional, device or a sainfoin special fool is possible,

In order to release à first flange of fog Spool; core of foe spOdf according to the invention, a tool Is preferably IhfiOfoteed info îlîfc Interior of foe spool eofo,: which st least partly disengages first and second latch elefossfe hr engagement wlfofirst and/or second latch: portions, respectively, A tool ; for secure and oonfoesf rocti ve disassembly ofthv sir w flange Ann* the spool: eons has irt example a eoni-cal stamp whose outer surfocohas an inclination to Sise aws of rotation which snfesianfisffy corresponds to the inclination of foe inner snrtace of the spool core. A ;rod is provided on fire stamp, by means of which foe latter is inserted into Ora interior and is poshed,: in partidufar pressed, towards foe first end of the spoof cord. Form and; «stent: of the; die are chosen sneh that this stamp can he poshed Into the am a of the Érsí latch portions and may abêtit there at the teer shelf sorthee of fop; spool : core, When foe: first latch, efernsois; of the lest flange engage: ltom the ostsids hr foe first latch portions : of foe spoof core, these are; pressed radially to the outside. by foe: extent portion of tire; eopleal stamp ahnttfog orr foe inside in tiro area of the first latch portions arid are dfsertgagod W # feast: loosened tom: the form-filling engagOOtest that; foe first fiange can be removed frost» the first e# pf foe sponleore, fetincipalfy, however, el other sorts: of special: tools are advantageously. For example, it is possible: to design: a topi In pefe a way shat ft «an fee inserted from the first end of foe spool core in its: timer, where Itigan^forpam-pi« with the support of a suitable mechanism -sports the : first fatefe elements pressing to thednÄ and engaging: with foe firstlatehportions radially to fog ontsidet ífofoértasóóf-tet press 1mm foe inner agafost foe first latch portions and engage with: foe snore, foe fool cam fee example, have foe forts of a belt with loops which is put in the area of the first latch portions sfofotd foe outer shell of foe spool core and ears fee tightened with a smtafele meehamsm, whereby foe first latch elements are pressed to the inside and in fois; way are disengaged with foe first foloh portions.

According fo the fovenffon, the first latch priions provided at foe find: end: of foe spoof 0« have difierehfe angular txrtiiions with respect to foe rotational: axis: of the spoof coil«:.: For example, foe first latch portions m plaeod by an mtgle of afeont dS A respectively, he. with respect to a first latch portion, foe next first iofdi portion is arranged with g misalignment of d5e and the following first latch portfon is arranged with a nfisaltgnment of 90* fending; os the twmtoee mâ distension of the :ßm Méh portos* these eas also fee displaced fey smaller or larger angles. Is principle, the angles can also save festerem dimensions. In total, this measure allows on the ose hand s favorable dklrifention of forces over the sorfsee over foo: fet flange sad therefore Its reliable axial fixation and, on foe other hand, a good seeUriasfioh agshlstiwistmgsso he reached.

It k pivfectedfoaf foe second latch portions sitnsted at foe first end of foe spool core have different angular posh lions with respect to dm rotational axis of the spool mm.ÁlsO: in this embodiment, foe second latch portions can fee displaced with respect to each other, for example by an angle: of about dS®, respectively - according to die number and foe dnnensfen of foe second latch -portions, however also: fey smaller or bigger or angles of dififerent sfeg: -, In fois embodiment of the second latch portions, & particularly reliable fixation of die ilfot riapges at the spool core against twist e&a fee reached. ;l%:Sef3hiÿj at least ope of foe second lafoh poriidP has ah angular position: which Coincides with foe angular pfeifioh of Ode of the fitst latch priions. This means fost at least a first and second latch portion have foe .same ringnia* position. Ilerebyj i ipshfielbariy secure pdsitiomsg on the one hand and: a reliable fixation of foe first flange on foe other hand is reached.

Preferably, thfoilrsf latch eleforiits arianged at foe fidrtgc have dififeeut .angular posMriti®;Wi#-ïè§Pï* Wliê rotational avis: of fos fitst flange; firdfershly, the: fitst laich elements are each wifo an nagln of about 45c' to each other. Depending an the nnatfeer andi foe dimension, of fos first latch nldments, these cad also fee distant foods each other by smaller or larger iSUgels:, Brfocipalyt foe angles can also have diflerent dimensions, hierefev, a cost-effective, particularly «yea distribution of forces over the. »fite« of the tlrst fisngos and, therefore, its reliable axial fixation and, op fos other tod, a good möástó0e:,í^sto:-^^»g-<m.ihe.ítofe8á.

Alternatively or additionally, foe second latsh elements have dirisrsnt angular positions according fe the rota:-tfooal axis of foe first flanges, lip paritcular, foe first fefofe elements are misaligned by an angle of about 45* to each other, respectively, Hid #to^.leP;Of:#a Igecfod fetch elements, these can also fee displaced by smaller or feiger angles or also by angles of different dimensions. Hereby, a reliable axial fixation of foe flanges with a reliable securixation against twisting at foe same time can be reached. it is particularly peletred that at feast one of foe second fetch elements has an angular position which ephteidcs with the angular position of one of the first fetch elements, Hereby, at least one first and one second latch element has the same angular poshion. In this eafoobmwaf,, a particularly secure positioning on foe one hand and, op foe other hand, a reidbfe fixation of foe first flange is enabled. in a further advsfoageous: cmfeodtmerfo foe second latch portions are formed as protrusions nnd/of recesses at foe first end of foe spool core, This represents a possibitify heing particularly easy to reallfo: two laleh: portions at foe spool core. At foe same time, a particnlarly good. scePrifoidn pgaiasi t wisring can be reached by foe protrusions and the recesses, respectively. ip particular, the gfofeusions: and recesses have an orientation parallel to the: rotational axis of fog spool core, respectively; The protrusions bed recesses are hereby preferably arranged la foe arcs of foe fece side of tile fitst: end of foe ; spool core and constitute hereby toothed ót easfelfefed extettsions and dents, respectively, at the shell of the spool core.

Alfanatively, fa profeisioss fad mcesses cas:, however,; also bave, m orientation parallel In the surfae of the shaft of fa spool core, respectively, Ifa professions, arranged ptefeélf írt the area of the lace side of the first end of fa spool core, sod recesses are, for example, formed as toothed or castellated extensions and dents, respectively. which preferably align with fa preforfaly tapered shell of fa spool core.

Provision cart bo made for the second latch elements being formed as recesses anchor professions at fa flange, In this way. the second latch elements can he rea&amp;ed at the first flange as well as a particularly good xeeafaatlon against twisting can be easily realized.

Preferably, fa fat latch elements and/or the second laieh dements are formed in one part with fa first flange. The first flange comprising latch elements can: hereby be prodneed in only one process step, for example as a die east component, which Is particularly savorfais: became of fee eost advantages with respect to fa advantageous «sage of the spool as gmgie-ose spool. tn a further advantageous embodiment, interspaces· are provided between fa first latch dements provided ai fa tlrsl flange, 'which are adapted to She particularly tapered: form of the spool yore that; the interspaces: In fa area of She first end abut when fa first latch elements of the first flanges engage wiith the dfaspondlng first; latch portions of the spool estre. Hereby, a favorable distribution ©f fabig; at fa: first flange: et the spool cptp if reached. In addition, a manual iopsefilng of the first flange fipfe; fa spool pore can he father hindered. forsforably, the interspaces have an inner portiba, viewed hr radial direction, whisk is inclined with an angle: between about 3·° and if5, ih particular about fe, with respect to fa rotational axis of fa flange. Hereby, a reliable abat of fa interspaces at the spool core can be realized in a simple manner.

In a further advantageous embodiment, provision is made for fa first latch elements being formed as axial protrusions at the first flange and the professions having a latch nose, respectively, which can engage with fa corresponding latch portions at the first end of the spool; core. Hereby, fa; axM protfalops run essentially parallel to the rotational axis of the first flanges. The respective latch noses pefaably pfefefa finm one end of the axial profession in direction fe the rotational axis, this means that these are orientated essfatfoliy In radia! direction to fa inside. Hereby, a secure fading of fa first ifaltfafanis of the first llahges m fa fifa latch podions at fa spooi core can he realized in fa easy manner, fafafely, the iatching nose has a in particular flat slant which, viewed hi radial direction, lies inside and inclined by m. aogle between sbont 2d® stud #* axis öf fa flange, in partieuiar about 20°. An opposite area of the fach nose to fa slant mas preferably normal to the rotational axis of the first flange, Thereby, the first latch elements are realized in a sort of barbed hooks, by which fa first flange is displaced easily fit a first axial dlreetfou oh; fisa first and of fa spool cofa in contrast thereto, after the latching of foe first: latch eiaipeuts: in the correspooding: first fach portions at foe spool com, cannot he removed noil* destructively inm foe spool: core: wifooutan:: additional special tool. In this way, m fa one band, an easy installation's wetas aseepre fixation of fa first flange is reached and, on fa other ifad, a simplemaaual dissnount-ing, which Is not desired, can be prevented.

According to foe invention, foe first latch elements, viewed in radial direction, engage írem foe outside in the first latfa portions at. the first end of fa spool core, fafcrakly, the first latch elements are hereby formed such that these eso be pressed during a winding of the spool core by ke wirfeipg material in direction of the latch portions:, fi ufeicntarly redudly to the Inside,: The fet latch efemeats- of die first flange latch hereby Horn the out-sida in the first Imeh portion» of the spool core. Thereby 1. IS: ensured: that, during; a winding: of fee spool whir winding material the pan?« can conte io rest no the first latch elements. The occurring forces: directed radially to the Inside :¾ to fik rotational axis offen flasge arid the spool core, respectively, contribute: to pressing the first l^eh cletbests to feu kslde <ps the i?M latch portmnSj whkh are therefore held particularly seem® m their posh don, i.e. engaged with these.

Preferably, the latch dements formed as protrusions with latch noses:are hereby dimensioned andikr shaped that a great share as possible of -he forces exerted by the winding imriSiM arc Iraossnitfed in radial direction on the first latch eletncnts. This ss preferably remized in that the protrttslotts of the first latch efeinents run essentially parallel to the rotational axis of the first flange drib the surface of the shell of the Spool core,

Additionally, it is advantageous if kb protrusions of the first latch elements arc so high wife respect to 'the base of the first flange facing the spool core that possibly several,, preferably ä rmfelfede of windings of the winding material eaa come to test np on these. Pre ferably, the height of the preiresioos is between 5 and 20 mm, particularly between 0 and 1:2 mm. With thèse vaines, on the one hand, high refeal feiges In a Woobd-up spool and, <p the other hand, also high, fences in an empty spool are ensured such tktfi te befit cases, a prtfeuipriy secure fix-, teg &amp; attained. T|e method: fer winding m Inventive spool with winding material has ihe fellowing steps: Setting, np the spool Oh: a Carrier spool which has o ptpforaifiy conical carrier spool core and »1 least: refiairge arranged at an end of the ctaricr sptxti cot® end starring to rotate the carrier spool, wi?erein dte spool ptd ot? tlm earner spool also starts to rotate k?d, ts thereby wöimd ftp with fed winding tnatcrial. This method: is charaeferiaed is? that the flange of the carrier spfîdl Is çoi^ied ternî^ilttifîgiy with the stsporlpf at least one actuator provided at the flange of tits carrier spoof with a fiangc of the spool. By thé: tetn?»fittipgly coupling, a pafilcolarly reliable transmission of torque &amp;om: file rotating carrier spool to ihe spool ip be: wound: tip with wlitditrg ssraferiai Is ertssned, in particular, ferais particularly advantageous at aeceicratkhidr feefeihg actions where higher torques: occur as?d can effect feat fee spool cannot or m longer reliably be drived % the rofetteg carrier: Spool and pat Into reiklom Thereby, a pari ticuhirly reliable winding of the invent ive spool with winding material is attained.

Preferably, fi?e spool is a single-use spool and the carrier spoof Is a ssmdard ot reusable spool, by which the spool Is feppisrted during fee winding. With respect to ihe preferred wall thickness of ihe spool core and the carrier spool core, respectively, the above explanations with respect: to ä: sipgfe-nse spool and ä reusable spool, respectively, apply accordingly, ihefefehly, ke inside of fite spool core of the spool cokes to rest at least: partly on the outside of fim spool core of fee carrier spool by the putting of the spool ore dm carrier spool and is firerehy frictionally coupled wife the same, This additional feiefiondi coupling suroîts fite transmission of torques of fee carrier spool on fife spool, which males fee winding of fee spoof even snore reliable, la addition, it: is preferred feat: the at least one, actuator provided at : the flange of fee carrier spool: engages at fee ffletiokd coupling In at feast one interspace hetween single ssrestkms formed at fife: iange of fed spool The formed aeristions primarily provided for a ifieehgnical sfrengfifehitsg of the flange serve at the same time m order &amp;í feafelMt the fern felpg, suefe Ibét «0 fefer provisions are necessary at the flange of the spool. lise inventive spool has tigere lore a simple buildup, the shove described method % winding s appor te a preferably conical carrier spool core and at least one Hange arranged at one end of the casrier spool core and is characterized is that Iha fenge of too carrier: spool Is pmvsfed with at least one carrier by which fe flange of the carrier spool css he femrishihgly coupled with s feige of a spool pot on the carrier spool.

As according Hange for such a carrier spool for ose in the above described method for winding a spool has a flat base and Is characterize# in that at least one actuator is provided at the hase by which the Hange of the eerier spool can be conpled fezn-Httingiy with a flange of a spool put ott the carrier spool.
