A suchlike apparatus and s suchlike method: have most recently beeardiselosed through foe publication by she apalicsat of Patern App1ic.stfmt;1i$0 20 I 0.Ό54955. Taaends ar id least one end of foe flexible-tube pieces in Dos case are földed through 9(1 degrees. The icsuking fold has is subsequently stamped, idfo: the flexible-tube material by a stamping device, such that the restoring force is /feduceifand the following bottom opeumg and bottom formal ion take piacé en/the whole in a more trouble-free manner and the bcttpum ulfunstsly nho correspond to the desired: shape.
The bags produced in this way meet the aforementioned requirement in full.:. A further problem has emerged;, however, |c the cotpsgof drop (Osts performed da suchlike bag:;, uluch bags·: bad: bees filled :#tbifc^prb.^||C:Np:'^ra:#ftöá to /burst open, preclseiy oh:the fold line. 'Tins gave rise to die object of and tba-methoi:-fe.r;pod.acfog:bap in such a way that the bursting of filled bags is avoided.
The object is aecom:p:!ls.bdd:by so apparatus according to Claim 1: and a method according to Æssim ft, À, foMtofoover deyleo / js: proposed, there fore, by mesas of which regions;«f the. two wails of one cud cap he folded over the imtfonwfoldmg edge by more thanifo degrees. This device is used: to Ibid the end of the flexible-f«be piece back ou itself ewer the folding edge. Once the flexible-tube piece has passed through said: device, a stamping element and a mating element act upon the end of the flestblevtubp piece, wherein botb: of said eforoents ave in contact with the same wall of the flexible-tube piece, Ip this case, however, the fwp elements act npomfoeTwo different sides of the feldlme,In this way, the end» of' the ftexibie--t ube pieces can be folded over is the: regions of the fold lines through 180 degrees and Can be pressed against one another, such that the fold line is of stronger configuration. Folding by tb« :MÂ|?!bvér.db.vfoe::caa be used to fold over theilexihis-tnhe piece end by appfoslmalely ISO: degrees., such/that the tlexible-fobe piece end arrives in the region between the stamping eiemetif and: thematiRg elemem vdtbpefiitfsiESuprlm
The present Invention has been based on the finding that the stamping: element according: to Wfo 3010/054985 damaged the woven: fobrie strongly with its quite sharp edge, such that said woven hibrid; was· no loögei' able to withstand the loads when dropped and: was torn. The stamping device according to the present Invention acts: simply by the application: of a strong pressure to the. ibid: line. To the process, the siamping element: and: the mating element bear against the: flexible-tubs piece with a sipificathly larger surfhoe compared/witlr the/shsfp edge, such thai/dhmags to and: associated weakening of the woven: labrie: are avoided. INo disadvantages have become apparent: in relation to the manufoettpe ma proper fashion o f bags having as fesmíit, tp which :^emtems«i»B*i;'Mà!«g-0vçr device makes a sign! fic&nt comributl os*
In s preferred embodiment of {he invention, the stamping element end {he assessated matitsg eleinenf comprise toilers. The flexible·'· ebe piece e??cl aseesdlnglj' eïà'sves in their roller sip, whereby the ibid line preferably rusts in the centre of the roHen;.
It is expedient to provide the oster surfaces of the stamping elemem and the maiing element with an elastic coating, in order to mM$. ao:y supping or dafing the stamping process.
In one advantageous embodiment, a drtye isassiped to the sfontpbi element aadforthemating element, by means of which dri ve the aforenmntioned elesnem or the two aforetnentioned elements can be driven at a eirenmforenihfi speed which is greater thaP ^e speed at which the ilexihle-tabe pieces are transported. This rather greater speed is designated in this ease as the "lead". The drive In this case can be an autonomoos motor for the stamping elesnem, and/or the mating element, which motor can he synchronised with the main drive of the appraim goth of the elements pan, of coarse, each be driven by its own individual drive. However, the drive can ^ so be provided via the main drive of the tnaehine, which preferably also drives the .ifso,?p©Äg:i$«ip# Tör tbc flexibie''tube pieces, A step-up; drive most then be provided betw-eea the drive and tho atorepieatloned; elements. The lead is used to tension the flexible-tabs piece ttt fhe:«ea«?poÄ| Pd creases occur and these are stamped thin the tnhe materia·, if possible.
It is particularly advantageous if a drive is assigtsed to only oae of the elements., and if the other element can he driven by way of a friction fit. The drive is preferably onto the mating element. The stamping element and tbe mating element can he provided with O-rings m their surfaces tor producing the frictional fit, which O-rings are elevaied in relation to the drcmnieremsal surfaces. in a further advantageous sofoodimem, the stamping element or the mating element can he positioned against the other element by mesms, of a fofee-exephg meehanlsm. of having a force exerted upon It is preferably the stamping elememp The posmouable element is preferably mounted at one end of â sever arra, upon the pite end of which the force-exerting <levice acts. The force-exerting device cart comprise a spring element, a pislots cylinder unit or a simple mass, which, is under the influence of gravity. The appropriate choice of she force enables the fold line to be stamped foiTreleafly strongly, buy wlthuat damage feeiitg Caused^ to the woven fotoie.
In order to determine the; folding edge, before the stamping devme acts «post tbe Adding edge, a folding element is provided, which has an operating edge for determining the folding edge. This operating bige runs parallel to the transporting difoetlotopf Un -addition IP'.the IÄr|g element, a forther guide element is proylded. as a epippoiledtipari # Én folding-over device, by means of which the cud of the flexible·tube piece can be folded over around the operating edge of the folding element, in this way, the end of the flexible-tube piece can already be folded hack on Itself for the most, pari, The folding eiemeot in ibis ease extends in a wedge-shaped manner as far as the folding edge of the flexible- tube pe®e, The guideMad. is disposed in an dncllasd: mahnet is relation to the tmssporttt)g direction of th® flesihle-nuhe pieces, whefoin it overlaps th® folding eiassest daring transport.
