CLASS INTERNATIONAL SWEDISH B 31 b54 b: 3 / PATENT. AND REGISTRATION REGISTRATION Ans. 4318/1958 was received on 5/5 1958 taken on 16/12 1963 YM ROLAND, CATTENIERES, FRANCE Cutting device for machines for the production of self-tapping passes, so-called square passes Priority requested Iran 16 December 1957 (France) The present invention relates to such a device with machines for the manufacture of self-opening packing passes, so-called square passes, that it becomes possible to easily manufacture such a pass provided with a perfectly sealed bottom, which can be used as packaging for goods of any kind, solid in solid form such as powder form, liquid form or even gaseous form.

Dylika phsar karakteriseras av att de ha fyra sidor, varav tva flata och tva invikta. Den storsta olagenheten med sadana pasar bestar, cla det galler forpackning av vissa varor (exempelvis livsmedel), i att deras botten i allmanhet icke ãr tillrackligt tat, varfor varan icke blir tillrackligt Unbar vid lagring. Such phsar are characterized by having four sides, of which two are flat and two are folded. The greatest inconvenience with such fits consists, as far as the packaging of certain goods (for example food) is concerned, in that their bottom is generally not sufficiently tight, so that the goods do not become sufficiently unbar during storage.

FOreliggande uppfinning har till syfte att undanroj a denna olagenhet och avser en sh'- dan anordning vid for framstallning av fyrkantpasar avsedda maskirter, att dessa bathe an hittills lampa sig for tillverkning av fullkomligt tatbottnade pasar av alla de storkkar, som kunna tillverkas med en viss ma-skin, och anordningen enligt uppfinningen bestar i, att maskinen ãr forsedd med en extra, reglerbar knivsats. The present invention has for its object to obviate this inadequacy and relates to a similar device in the manufacture of squares intended for the production of square passes, that these baths have hitherto been suitable for the manufacture of perfectly ground passes of all the storks which can be manufactured with a certain machine, and the device according to the invention consists in that the machine is provided with an extra, adjustable knife set.

Uppfinningen avser att mojliggora framstallning av pasar, vilkas botten ãr vikt och klistrad eller svetsad i enlighet med forut kin& metoder samt uppvisar tillslutningstungor av bestamda dimensioner, vilka mojliggora dels en fullkomligt Mande tillslutning av pasbottnen, dels en bekvam och obehindrad utformning av densamma genom hopvikning av dess olika delar. The invention is intended to enable the production of passes, the bottom of which is folded and glued or welded in accordance with prior art and methods, and has closing tongues of certain dimensions, which enable a completely smooth closure of the pass bottom, as well as a comfortable and unobstructed design thereof. its different parts.

Figs. 13 and 14, finally, show a cross-cutting apparatus, which according to the invention is provided with an additional, adjustable set of knives, by means of which the shortened bottom closing flaps, which constitute the main pitcher of the invention, are obtained.

Ordningsfoljden mellan operationerna hos maskinen är foljande: Operationer av forut kand typ: I en pasmaskin f8r tillverkning av pasar enligt foreliggande uppfinning (fig. 12) lOper den enkla eller samma:nsatta (fodrade) pappersbanan 1 Iran en forradsrulle a och passerar darefter genom en apparat b, vilken monstret C i fig. 6 anbringar ett bindemedel (varmlim eller annat lampligt bindemedel) ph de delar av banan 1, som skola bilda pasarnas botten. Det salunda piforda bindemedlet avkyles pa en kylvals d. Fig. 5 visar komponenterna a, b och d i stone skala. The order between the operations of the machine is as follows: Operations of the prior art type: In a pass machine for the manufacture of passes according to the present invention (Fig. 12), the simple or the same: inserted (lined) paper web 1 Iran a supply roll a and then passes through a apparatus b, in which the sample C in Fig. 6 applies a binder (hot glue or other suitable adhesive) to the parts of the web 1 which are to form the bottom of the passes. The thus applied binder is cooled on a cooling roller d. Fig. 5 shows the components a, b and d on a stone scale.

I fortsattningen av pappersbanans Iopp lag-gas forst p vanligt satt snitt i densamma pa de stallen, dar pasbottnarna skola hildas, sasom visas vid e, f, g och h i fig. 8, dvs. i form av fyra parallella, i frammatningsriktningen lopande snitt. In the continuation of the paper web Iopp lag-gas first in the usual way cut in the same in the stables, where the passport bottoms are to be hilled, as shown at e, f, g and h in Fig. 8, ie. in the form of four parallel, running sections running in the feed direction.

Den for uppfinningen sarskilt utmarkanoperationen: Pappersbanan 1 passerar darefter till en andra, reglerbar knivsats, vilken är Urineteeknande for den modifikation, som enligt foreliggande uppfirming Eiretagits vid de Rant kande maskinerna: for framstallning ay fyrkantpasar; denna reglerbara knivsats (fig. 13 -och 14) utfor i banan 1 tva nya snitt, betecknad med i och j, vilka lopa vinkelratt mot snitten e, f, g, h pa onskat avstand fran det avsedda pasamnets underkant, sft att det i papperet 1 bildas tva sammansatta snitt, vart- d:era med samma form som bokstaven H. Maskinen enligt fig. 12 Or sá anordnad, att dessa H-formiga snitt utfOras i de delar 2 och 3 av pasamnet (fig. 1), vilka skola bilda de bottenpartier, vilka ligga i forlangningen av pasens hada motstaende flatsidor 4 och 5, mellan vilka de hada &riga sidorna Aro invikta. The field operation in particular for the invention: The paper web 1 then passes to a second, adjustable set of knives, which is Urinary for the modification which, according to the present invention, has been performed on the cutting machines: for production in square passes; this adjustable set of knives (Figs. 13 and 14) makes two new cuts in the web 1, denoted by i and j, which run perpendicular to the cuts e, f, g, h at the desired distance from the lower edge of the intended pass blank, so that in the paper 1 forms two composite sections, each of which has the same shape as the letter H. The machine according to Fig. 12 is arranged so that these H-shaped cuts are made in the parts 2 and 3 of the fitting blank (Fig. 1) shall form the bottom portions, which lie in the demand of the pasen hada opposite flat sides 4 and 5, between which the hada & riga sides Aro fold.

Under den fortsatta frammatningen av pappersbanan 1 i maskinen enligt fig. 12 omfor- mas banan till en s. k. hylsa A med invikta sidor (fig. 2). Da denna hylsas frammatning fortsatter, kapas den pa kant salt till for de avsedda pasarna lampliga, forutbestamda langder. Genom detta tvargaende kapsnitt, som avgransar pasens nedre kant, frigoras tvâ rektangulara lappar eller blad, vilka bildas av nedre delen ay vardera av de genom H-snitten tillskurna tungorna. Dessa lappar eller bind falla bort, &A att det av de genom H-snitten utskurna tungorna endast aterstar tva kantpartier 6 och 7 (fig. 1), som utgora de for uppfinningen utmarkande tillslutningstungorna. During the continued feeding of the paper web 1 in the machine according to Fig. 12, the web is transformed into a so-called sleeve A with folded sides (Fig. 2). As the advancement of this sleeve continues, it is cut on the edge of salt to suitable, predetermined lengths for the intended fit. Through this transverse cutting section, which delimits the lower edge of the pass, two rectangular patches or leaves are released, which are formed by the lower part of each of the tongues cut through the H-sections. These patches or napkins fall off, and that of the tongues cut out by the H-cuts only two edge portions 6 and 7 remain (Fig. 1), which constitute the closing tongues marking the invention.

Vikningen: Vikningsoperationerna for pasbottnens bildande genomforas pa forut kant satt, och un- der vikningsforloppet erhalIes automatiskt vid 10 langs en remsa av c:a 1 cm bredd Overlappning mellan de hada lodrata halfterna 8 och 9 am pasens botten (B, fig. 2). De hada kantpartierna eller tillslutningstungorna 6, 7 med vidsittande trapetsformiga bottenflikar vikas darefter pa kant salt ned mot den innanforvarande rektangulara delen av pasbottnen (fig. 3 och 4). The folding: The folding operations for the formation of the passport bottom are carried out on the front edge set, and during the folding process is obtained automatically at 10 along a strip of about 1 cm width. . The had edge portions or closing tongues 6, 7 with wide trapezoidal bottom flaps are then folded on edge salt down towards the inner rectangular part of the fitting bottom (Figs. 3 and 4).

Fore utmatningen passerar den salunda fardigformade pasen genom en anordning (fig. 10, 11), vilken uppvisar ett segmentformigt uppvarmningsorgan, som anlagges mot pasens botten och trycker denna mot ett underlag, sâ att man genom varmehehandling astadkommer hopklistring av alla de mellanliggande partier av pasbottnen, vilka tidigare paforts klister eller Ern, sa att pasbottnen Mir fullstandigt tat. Before discharging, the thus-finished pass passes through a device (Figs. 10, 11), which has a segment-shaped heating means, which is applied to the bottom of the pass and presses it against a substrate, so that all the intermediate parts of the pass bottom are glued together by heat treatment. , which previously paforts klister or Ern, said that pasbottnen Mir completely tat.

Uppfinningens nyhet ligger i det forhallandet, att tillslutningstungorna: 6 och 7 icke nA anda nal till underkanten pa pasamnet, utan tvartom alltid aro avkortade. De f5r uppfinningen sarskilt utmarkande tvargdende snit- ten i och j utforas namligen alltid pa ett bestamt, storre eller mindre avstand fran pasamnets underkant, varvid detta avstand for en pase av given storlek är sá malt, att de av- kortade tillslutningstungorna aro tillrackligt stora for att sakerstalla en effektivt tatande tillslutning ay pashottnen och samtidigt sa sma, att den inre av desamma icke pa nagot satt verkar hindrande eller kan skrynklas i saraband med hopvikningen ay bottnen (fig. 3 och 4) och den yttre av tungorna darvid icke kommer att utskjuta utanfor den fardiga pasbottnens narbelagna hornkant. The novelty of the invention lies in the fact that the closing tongues: 6 and 7 do not reach the bottom of the pass blank, but on the contrary are always shortened. The transverse cuts in and j which are particularly distinctive for the invention are always made at a certain, greater or lesser distance from the lower edge of the fitting, the distance for a step of a given size being so large that the shortened closing tongues are sufficiently large for to ensure an effective sealing closure on the bottom and at the same time so small that the inside of them does not in any way prevent or can be wrinkled in conjunction with the folding of the bottom (Figs. 3 and 4) and the outside of the tongues will not protrude. outside the near-angled corner of the finished pass base.

Som bekant kan en och samma pasmaskin — — anvandas for tillverkning av pasar av ett antal olika storlekar. Uppfinningens mest vasentliga fordel ligger dari, att man alltefter den for tillverkning valda passtorleken kan reglera den extra knivsatsens lage pa sa.- dant satt, att man. erhaller avkortade tillslutningstungor av den storlek, som lampar sig bast for vikningsoperationens genomforande. Eller, med andra ord: genom att pa helt enkelt satt reglera den extra knivsatsens lage, kan man med en och samma pasmaskin framstalla pasar av alla mom maskinens kapacitet fOrekommande storlekar, vilkas botten alltid uppvisar de ovan angivna fordelarna med avseende pa saval tathet som lattvikbarhet, medan man med de konventionella maskinerna uta.n extra, reglerbar knivsats endast kan tillverka ett enda pasformat, vid vilket pasbottnen har exakt de ovan angivna fordelarna. As is well known, one and the same fitting machine - - can be used for the manufacture of fittings of a number of different sizes. The most essential advantage of the invention lies in the fact that, depending on the fit size chosen for manufacture, the position of the extra knife set can be regulated in such a way that one. receives shortened closing tongues of the size which are best suited for carrying out the folding operation. Or, in other words: by simply regulating the position of the extra knife set, one can with one and the same fitting machine produce fittings of all sizes of the machine's available sizes, the bottom of which always has the above-mentioned advantages in terms of both tightness and foldability. , while with the conventional machines uta.n extra, adjustable knife set can only produce a single fitting format, in which the fitting base has exactly the above stated advantages.

Uppfinningen ar givetvis icke begransad till den har beskrivna utforingsformen, utan olika modifikationer aro mojliga Mom uppfinningstankens ram. The invention is of course not limited to the embodiment described, but various modifications are possible within the scope of the inventive concept.

Det ar tydligt, att den tatbottnade pasen enligt uppfinningen kan tillverkas saval av vanligt papper som av fodrat eller skiktat papper, hopklistrat med lim, klister, vaxbindemedel, lack eller plastmaterial, och uppfinningens karnpunkt ligger dels i den speciella tillskar- ningen av de avkortade tillslutningstungorna pa sadant satt, att man erhaller en pase med fullkomligt tat och bekvamt och slatt hop- vikbar botten, dels i den komplettering av den forut kanda maskinen for tillverknin:g av fyrkantpasar med en extra, reglerbar, tvarskarande knivsats, som mojliggor tillskarningen av namnda: avkortade tillslutningstungor. It is clear that the tat-bottomed pass according to the invention can be made from plain paper as well as from lined or layered paper, glued together with glue, glue, wax binder, varnish or plastic material, and the core of the invention lies partly in the special cutting of the shortened closing tongues in such a way as to obtain a pass with a perfectly tight and comfortable and smoothly foldable bottom, partly in the addition of the prior art machine for the manufacture of square passes with an extra, adjustable, transverse knife set, which enables the cutting of the said : shortened closing tongues.
