Det finnes olika konstruktioner av denna typ alltifran det nat av rektanglar eller kvadrater, som erhalles med hjalp av uppskurna och sammansatta lameller eller band, till olika geometriska former astadkomna med hjdlp av limmade band. Bland dessa sistnamnda former erhalles en del med hialp av band, som i forvag aro formade till bildning av caller med lamplig form och successiva band, som aro hoplimmade i kontaktzonerna. Andra eel]ikarnor astadkommas med Nall) av band, som Oro hoplimmade i platt tillstand med forskjutna limzoner, varefter det limmade materialet expanderas, sh att cellerna utveeklas mellan limfogarna. There are various constructions of this type, ranging from those of rectangles or squares obtained by means of cut and assembled slats or strips, to various geometric shapes created by means of glued strips. Among these latter forms some are obtained with the aid of bands, which are predominantly formed to form callers with a suitable shape and successive bands, which are glued together in the contact zones. Other eel] ikarna are made with Nall) of strips, which Oro glued together in a flat state with staggered glue zones, after which the glued material is expanded, sh that the cells are developed between the glue joints.

Varje typ av cellkarna med hoplimrnade band liar sina fordelar och sina nackdelar. Each type of cell band with glued bands has its advantages and disadvantages.

Med en formning i forvag kan man bibringa cellerna olika geometriska former, medan tillverkningen blir invecklad och besvarlig, varfor denna typ har fatt obetydlig anvandning. Ur ekonomisk synpunkt foredrar man material, som erhalles genom hoplimning i platt till-stand och efterfoljande expandering. Med detta forfarande begransas .emellertid cellformen i praktiken till sexkantiga caller eller bikakemonster. Expanderingen minskar vidare bred-den i forhallande till blockets ursprungliga bredd fore expansionen. Expan.sionen .a.ger vi dare icke rum regelbundet utan blir starkare vid andarna an i mitten, sa att cellkarnan latt far konkav profil vid de langsghende kanterna. With a pre-formulation, the cells can be given different geometric shapes, while the production becomes complicated and cumbersome, for which reason this type has received insignificant use. From an economic point of view, materials are obtained which are obtained by gluing together in a flat state and subsequent expansion. In this method, however, the cell shape is in practice limited to hexagonal callers or honeycomb samples. The expansion further reduces the width in relation to the original width of the block before the expansion. The expansion does not take place regularly, but becomes stronger at the spirits than in the middle, so that the nucleus has a concave profile at the longitudinal edges.

Foreliggande uppfinning hfinfOr sig till ett material bestaende av hoplimmade band eller banor avsett for expandering, med vilket man icke endast undviker dessa olagenheter under bibehallande av enkel och billig tillverkning utan aven efter expansion erhaller plattor med en bredd, som atminstone dr d:ubbelit sd stor soni det ursprungliga blockets. The present invention relates to a material consisting of glued-together strips or webs intended for expansion, with which not only these imperfections are avoided while maintaining simple and inexpensive manufacture, but also after expansion obtaining plates with a width which is at least three times as large. soni the original block.

Detta material kannetecknas av att det bildas av band, som aro dubbelveckade i D form och hoplimmade med varandra langs veckens undersida och oversida. This material can be characterized by the fact that it is formed by bands, which are double-folded in D shape and glued together along the underside and upper side of the folds.

Med dubbelveck avses veck av den typ, som allmant henamnes bdtveck, vid vilka bandet omvaxlande är vikt i en riktning och i motsatt riktning. Enligt en utforingsform är detta dubbelveek utfort sa, att tva lika breda stycken av bandet aro forbundna medelst ett hogst half-ten sh brett stycke. De successiva banden aro lagda pa varandra med en forstallning, som svarar mot denna halva bredd. By double folds is meant folds of the type commonly referred to as folds, in which the band is alternately folded in one direction and in the opposite direction. According to one embodiment, this double fold is designed so that two equally wide pieces of the band are connected by means of a maximum half-ten sh wide piece. The successive bands are laid on top of each other with a stature corresponding to this half width.

Man limmar ihop tvh pa varandra lagda banor, som i praktiken med en farstallning med denna halva bredd av ett band i forhallande till angransande band eller genom frammatning frail tva olika vikningsanordningar. Two webs are laid together on top of each other, as in practice with a parking space with this half width of a strip in relation to adjacent strips or by feeding from two different folding devices.

Det salunda sammansatta materialet expanderas genom dragning langs tva motstheade kanter. Maximal expansion i en riktning ger ett material med rektarigulara eller kvadratiska cellar, vid vilka sidorna aro forstallda Iran den ena raden till den andra. Vid expansion av detta material Okas bade langden och bredden. The thus assembled material is expanded by drawing along two opposite edges. Maximum expansion in one direction gives a material with rectarigular or square cells, at the sides of which are represented Iran one row to the other. When expanding this material, Okas has both length and width.

Detta material framstalles genom limning i plant tillstand. Det kan framstallas med hjalp av band eller banor, varvid banden eller banorna arc veckade sanat sedan hoplimmade fOr att slutligen expanderas. Dã man anyander ha-nor, kan materialet skaras till remsor fore expansionen. This material is produced by gluing in a flat state. It can be made with the aid of ribbons or webs, the ribbons or webs being folded and then glued together to finally expand. If any other ha-nor, the material can be cut into strips for expansion.

Denna tillverkning kan genomf8ras kontinuerligt. For veckningen kan man anyanda vanliga maskiner for veckning ay material. Limningen och den eventuella skarningen genomfores med vanliga medel. This production can be carried out continuously. For folding, one can use anyanda ordinary machines for folding ay material. The gluing and any cutting is carried out with ordinary means.

Uppfinningen kommer i det Raj ande att beskrivas narnaare med hanvisning till bifogade ruining, vilken som exempel visar nagra utforingsformer. Fig. 1 är en perspektivvy av materialet fore expansionen. Fig. 2 visar det nor- 2— — malt expao derade materialet. Fig. 3 visar ett annat expansionssatt. Fig. 4 visar denna utf5- ringsform i schematiska snitt. Fig. 5 visar schematiskt tillverkningen av materialet. The invention will be described in more detail below with reference to the accompanying ruin, which shows by way of example some embodiments. Fig. 1 is a perspective view of the material before the expansion. Fig. 2 shows the normally exposed material. Fig. 3 shows another expansion set. Fig. 4 shows this embodiment in schematic sections. Fig. 5 schematically shows the manufacture of the material.

Materialet enligt uppfinningen at sammansatt av flera hoplimmade band. Varje band dr dubbelvikt, dvs. omfattar en del 10 med bred-den a, tva delar 11, som aro mycket kortare och vikta 5ver delen 10 samt fasta i en del 12 med bredden a, som spiv är forbunden med efterfoljande del 10 genom en mellandel 11. De salunda veckade banden laggas p varandra, so_ att delen 10 i ett hand fastlimmas pa delen 12 i foregfiende band. The material according to the invention is composed of several glued tapes. Each band dr double weight, ie. comprises a part 10 with width a, two parts 11, which are much shorter and folded over part 10 and fixed in a part 12 with width a, which spig is connected to subsequent part 10 by an intermediate part 11. The salunda pleated bands laid on top of each other, so that the part 10 in one hand is glued to the part 12 in the preceding band.

Det av hoplimmade band bestaende materialet omfattar salunda begynnelsen till celler i form av oregelbundna, konvexa sexhorningar, i vilka de breda, motstaende sidorna bildas av delarna 10 och 12 samt de smalare sidorna av delarna 11. The material consisting of glued strips thus comprises the beginning of cells in the form of irregular, convex hexagons, in which the wide, opposite sides are formed by the parts 10 and 12 and the narrower sides of the parts 11.

Delarna 11 kunna vara met eller mindre utpraglade. Den slutliga expansionen av materialet beror namligen pa deras bredd. The parts 11 can be matt or less pronounced. The final expansion of the material depends on their width.

Del arna 11 utforas lampligen med en bredd, som dr i huvudsak lika med halften av delarnas 10 och 12 bredd a. The parts 11 are suitably made with a width which is substantially equal to half of the width a of the parts 10 and 12 a.

Da man dram nt materialet i riktningen for pilarna A vinkelratt mot banden, antar det formen enligt fig. 2 och bildar pa sin hojd ett cal av rektangulara eller kvadratiska celler 13 vilkas sidor med bredden a bildas av delarna 10 och 12 och de bagge ovriga motstaende sidor av dubbla bredden pa delarna 11, dvs. ocksd lika med a, om delarnas 11 bredd är a/2. Dessa celler aro uppradade i angransande rader. Varje rad Or forstalld i forhallande till angransande rad ett stycke, som svarar mot bredden pa. en smal sida 11. Varje cells sidor bildas av dels de hoplimmade delarna 10 och 12 av tva angransande band dels av delar 11 bildade genom utratning av vecken till rat Onkel. When the material is rotated in the direction of the arrows A perpendicular to the bands, it assumes the shape according to Fig. 2 and forms at most a cal of rectangular or square cells 13 whose sides with the width a are formed by the parts 10 and 12 and the other ram opposites sides of double the width of the parts 11, i.e. also equal to a, if the width of the parts 11 is a / 2. These cells are lined up in adjacent rows. Each row Or is formed in relation to the adjacent row a piece, which corresponds to the width of. a narrow side 11. The sides of each cell are formed by the glued-together parts 10 and 12 of two adjacent bands and partly by parts 11 formed by eradicating the folds to rat Uncle.

Om man utgaende fran fig. 2 drar ut cellkarnan parallellt med banden i riktningen_ for pilarna B, erhaller man sa.som visas 1 fig. 3 hexagonala celler 14 bildade av oregelbundna sexhorningar, eftersom sidorna 11 aro smalare an de m.otstaende sidorna 10 och 12. Starting from Fig. 2, if the cell nucleus is pulled out parallel to the bands in the direction of the arrows B, hexagonal cells 14 formed by irregular hexagons as shown in Fig. 3 are obtained, since the sides 11 are narrower than the opposite sides 10 and 12.

Den ovan beskrivna cellkarnan kan fram- stallasvarje lampligt material, sasom kar- tong, impregnerat eller oimpregnerat papper, metall eller plast. Limningen kan genomforas med nagot lampligt, vanligt Um eller genom varmning av termoplastiskt material. Om det anvanda materialet bestar av en metall kan sammanfogningen fistadkommas genom 15dning eller svetsning. The cell nucleus described above can be made of any suitable material, such as cardboard, impregnated or unimpregnated paper, metal or plastic. The gluing can be done with something suitable, ordinary Um or by heating thermoplastic material. If the material used consists of a metal, the joining can be accomplished by welding or welding.

Det expanderade materialet kan anvandas fOr onskad inkladning. Det kan forses med tackskivor av nagot lampligt material, sfisom kryssfaner, metal', gips, gipsplattor och ashestcement, sa att det bildas platter, mellanvaggar eller annat byggnadsmaterial. The expanded material can be used for unwanted loading. It can be provided with roofing sheets of some suitable material, such as plywood, metal, plaster, plasterboard and ash cement, so that slabs, partitions or other building material are formed.

Ett sadant material har utomordentlig hall fasthet on framfor alit regelbunden hallfasthet i alla punkter pa grand av de regelbundna raderna av kvadratiska celler, som korsa varandra. Such a material has excellent hall strength over rather than regular hall strength in all points on the grand of the regular rows of square cells, which cross each other.

FOr framstallning av detta material utgar man fran band 20, se fig. 4, i vilka man genom vikning formar veck 21 och 22 med motsatt riktning. For the production of this material, one starts from strip 20, see Fig. 4, in which folds 21 and 22 are formed in the opposite direction by folding.

Delarna 11 utfOras lampligen med en bredd, som är halften av delamas 10 och 12. Pa grund harav kunna tva delar 11 fallas ned pa delen 12 och fullstandigt tacka denna. The parts 11 are suitably made with a width which is half of the parts 10 and 12. Due to this, two parts 11 can be dropped onto the part 12 and completely thank it.

Pd det salunda veekade bandet anbringas ett limskikt 23, varefter man placerar ett identiskt likt, andra band pa limskiktet. Detta andra. band 20 dr emellertid fOrskjutet eller vant i forhallande till det fOregaende bandet, si att delarna 10 limmas fast i delarna 12 i det foregaende bandet 20. An adhesive layer 23 is applied to the thus softened tape, after which an identical, second tape is placed on the adhesive layer. This second. belt 20, however, is offset or used in relation to the preceding belt, in that the parts 10 are glued to the parts 12 of the preceding belt 20.

Bandet 20' overdras sedan med lirn vid 23' f5r fastlimning asv ett andra band 20" osv. The band 20 'is then coated with lirn at 23' for gluing etc. a second band 20 "etc.

I stallet f8r att utga fran band kan man vanligen med fordel utga frail banor 24, se fig. 5, som rullas av fran en rulle 25 och styras av valsar 26 och 27. Instead of starting from belts, it is usually advantageous to start from free webs 24, see Fig. 5, which are rolled off from a roll 25 and guided by rollers 26 and 27.

Banan 21 passerar mellan linjalerna 28 och 29, som aro anordnade pa lampligt inbordes avstand och bibringas lampliga rorelser for att astadkomma de vid 30 visade dubbelvecken. The web 21 passes between the rulers 28 and 29, which are arranged at a lamp-shaped distance and are subjected to lamp-like movements in order to achieve the double folds shown at 30.

Pa den salunda veckade hanan 30 anbringas ett limskikt med en vals 31. Banan kapas sedan transversellt till element riled lamplig langd, vilka falla ned i en central kanal, i vii-ken. de staplas pa varandra med lOmplig for-&Wining och limmas fast vid varandra vid 32. An adhesive layer with a roller 31 is applied to the thus folded tap 30. The web is then cut transversely into elements of suitable length, which fall down into a central channel, in the fold. they are stacked on top of each other with suitable for- & Wining and glued to each other at 32.

Den salunda bildade stapeln skares sedan bangs linjerna 33 med ett inbordes avstand, som svarar mot tjockleken pa de cellkarnor, vilka skola framstallas. Man erhaller pa detta salt block, vilka sedan expanderas pa det ovan beskrivna och i fig. 2 och 3 visade sattet. The stack thus formed is then cut along the lines 33 by an inboard distance corresponding to the thickness of the nuclei to be produced. This salt block is obtained, which is then expanded in the manner described above and shown in Figs. 2 and 3.

Den ovan beskrivna utforingsformen utgor endast ett belysande exempel, och kan modifieras, utan att man darfor overskrider uppfinningens ram. The embodiment described above is only an illustrative example, and can be modified without exceeding the scope of the invention.
