Pohištvo z nosilnimi telesi iz kartonskega laminata; postopek in priprava za izdelavoFurniture with supporting bodies made of cardboard laminate; process and preparation for manufacture
Izum zadeva postopek za izdelavo pohištva in delov zanj, pri katerem se s prešanjem poveže in utrdi z lepilom za lepljenje v hladnem oslojen in v plasteh, naloženih druga na drugo, v laminatno oblikovno telo zložen karton ali vlakninska snov kartonske vrste.The invention relates to a process for the manufacture of furniture and parts thereof, in which it is bonded and cured by molding to cold-coated adhesive and layers of cardboard or fibrous material of cardboard type in a laminate body.
Iz spisa uporabnega vzorca DE-U1-82 09 206 je znano, da se sedežni deli stolov, hrbtni nasloni ali sedežne lupine delajo iz lepenke ali laminiranega kartona, pri čemer se iz lepenke ali kartona izštancani oblikovani deli, ki so oslojeni z lepilom za lepljenje v hladnem, vložijo v prešo in se tam stisnejo, tako da tvorijo obliki prirejeno lupino sedežnega dela ali naslona, brž ko je lepilo strjeno in je temu sledilo razformanje laminata.It is known from the application specimen DE-U1-82 09 206 that the seats of the chairs, the backrests or the seat shells are made of cardboard or laminated cardboard, whereby the cardboard or cardboard is made of molded parts which are free from adhesive for bonding in the cold, they are pressed and pressed there to form a custom shell of the seat or backrest, as soon as the adhesive has hardened and the laminate has disintegrated.
Ta postopek ima to pomanjkljivost, da se da po njem narediti le zmerno ukrivljene oblikovne dele in da je čas držanja obdelovanca v orodju do strditve lepila sorazmerno dolg, tako da sta preša in orodje dolgo zasedena. Razen tega nastaja mnogo odpadka pri štancanju.This process has the disadvantage that only moderately curved molded parts can be made afterwards and that the workpiece holding time in the tool until the adhesive has hardened is relatively long, so that the press and tool are long occupied. In addition, there is a great deal of waste in stamping.
Naloga izuma je, razkriti nov postopek, s katerim se dajo v kratkih časih oblikovanja izdelati pohištva in pohištveni deli tudi z ostrimi ukrivljenji, kot tudi ustvariti po njem izdelane nove pohištvene dele in pohištvo ter pripravo za izvedbo postopka.It is an object of the invention to disclose a new process by which furniture and furniture components can be produced in short design times with sharp curvatures, as well as to create new furniture parts and furniture made therefrom and to prepare for carrying out the process.
Rešitev je v tem, da karton kot kartonsko progo po nanosu lepila vijemo v votel navitek in ga zatem v operaciji prešanja oblikovno prešamo med notranjim in zunanjim telesom kalupa, čemur sledi razformanje z odstranitvijo jedra s temu sledečo strditvijo.The solution is to roll the cardboard as a cardboard line after applying the adhesive into a hollow reel and then in the pressing operation it is formally pressed between the inner and outer body of the mold, followed by disintegration by removing the core with this subsequent curing.
Prednostne izvedbene značilnosti so predstavljene v podzahtevkih. Pohištva in pohištveni deli nove vrste kot tudi priprava za izvedbo postopka so podani v vzporednih zahtevkih.Preferred performance characteristics are presented in the sub-claims. Furniture and furniture components of a new type as well as preparation for the process are given in parallel claims.
Postopek nove vrste temelji na tvorbi navitka materiala kartona ali vlakninske snovi, ki ga je treba laminirati. Lepilo za lepljenje v hladnem, ki se še ni vezalo, omogoča z notranjim in zunanjim pritisnim orodjem doseči dokončno obliko surovca iz navitka, pri čemer sledi utrjevanje in zgoščanje (kompaktnost) laminatnih plasti, kar pomeni povečano sprijemljivost lepila. Surovec je tako oblikovno stabilen, da ga lahko takoj vzamemo iz preše, čemur sledi dokončna strditev lepila v vmesnem skladišču. Že pred strditvijo je možna tudi nadaljnja predelava, kot vnos opor in nalepljenje končnih zapor (zapiral), tako da ne pride do nikakršnega seštevanja več strjevalnih časov.The process of the new type is based on the formation of a reel of cardboard or fibrous material to be laminated. Cold bonding adhesive, which has not yet been bonded, allows the internal and external pressing tools to achieve the final shape of the workpiece from the coil, followed by the hardening and compacting (compactness) of the laminate layers, which means increased adhesion of the adhesive. The blank is so formally stable that it can be immediately removed from the press, followed by final curing of the adhesive in the intermediate storage. Prior to curing, further processing is also possible, such as insertion of supports and gluing of end closures (closures), so that no more curing times are added.
Pri preoblikovanju in prešanju lahko v istem orodju s pomočjo pnevmatsko ali hidravlično krmiljenih pehal vgradimo vijačne vložke, preboje ipd., če že ne moramo pehala in vstavljalnike razporediti neposredno v čeljusti preše.When forming and pressing, the same tools can be fitted with pneumatically or hydraulically controlled pegs in the same tool if screws, punctures, etc. are to be fitted, unless the pegs and the inserts are arranged directly in the jaws of the press.
Surovce se da - glede na potrebe - z rezi, narejenimi z žaganjem, deliti ali členiti, pri čemer izoblikujemo npr. letvasto podzgradbo sedežnega dela ali naslonske ploskve.Raw materials can be split or split, as required, with saw blades, for example. slatted sub-structure of the seat or backrest.
Povezave z zgradbami sedežnega dela ali zapor (zapiral) kot tudi med več laminatnimi deli gre racionalno izdelati s pomočjo skobnih zvez, ki se v laminatu izvrstno držijo ne glede na smer, iz katere so skobe nastreljane.Connections to the buildings of the seat or locks (closures), as well as between several laminate parts, should be rationally made with the help of staple joints, which adhere perfectly in the laminate regardless of the direction from which the staples are fired.
Laminat se vije v navitek smotrno iz surovega reciklirnega kartona vrste embalažni papir, sestoječega iz starega papirja in/ali temljne snovi iz stare lepenke. Uporabimo lahko tudi svežo (novo) lepenko ali svež papir. Kot vezno sredstvo uporabimo lepilo za lepljenje v hladnem ali toplem ali druga lepila. Kot lepilo za lepljenje v hladnem je dobro primerno knjigoveško lepilo, ki je brez škodljivih snovi, npr. PVA, t.j. polivinilalkohol. Za nosilno ploščno ali stensko zgradbo ležalnega ali sedežnega pohištva zadoščata 2 do 25 plasti navitka kartona 25 do 1200 g/m2.The laminate is rolled up conveniently from raw recycled cardboard of a type of packaging paper consisting of old paper and / or dark cardboard. Fresh (new) cardboard or fresh paper can also be used. We use adhesive for cold or hot bonding or other adhesives as bonding agent. Binding adhesive, which is free from harmful substances, such as e.g. PVA, ie polyvinyl alcohol. 2 to 25 layers of cardboard winding 25 to 1200 g / m 2 are sufficient for the load-bearing panel or wall structure of reclining or seating furniture.
Priprave za izvedbo postopka vitja in prešanja so smotrno več metrov široke, tako da se da na eno operacijo vitja izdelati najmanj eno telo ležalnega pohištva ali več delov za izdelavo naslonov za roke. Navijalno jedro prednostno sestoji iz osnovnega telesa, ki lahko ekspandira in na katero v odvisnosti od modela, ki ga želimo proizvesti, namestimo njemu prirejene nastavke. Navijalno jedro je zamenljivo držano v stojalu, ki vsebuje navijalni pogon. Smotrno lahko uporabimo izmenično dve navijalni jedri, pri čemer vsakokrat eno spravimo v prešo, čemur sledi razformanje, medtem ko drugo ovijamo. Tudi lahko navitek snamemo z navijalnega jedra in ga nataknemo na posebno jedro za prešanje, tako da navijalna priprava obratuje domala brez prekinitve.The arrangements for carrying out the stitching and pressing process are expediently several meters wide, so that at least one body of the furniture or several parts for the manufacture of armrests can be produced per one stool operation. Preferably, the winding core consists of a base body which can expand and to which, depending on the model we wish to manufacture, we attach fittings adapted thereto. The winding core is interchangeably held in a stand containing the winding drive. It is advisable to use two winding cores alternately, each one being pressed, followed by disintegration, while the other is wrapped. We can also remove the winding from the winding core and place it on a special core for pressing, so that the winding device operates almost without interruption.
Kartonska proga poteka od zalogovnega navitka preko zalogovne zanke k valju za nanos lepila in od ondod k navijalniku. Da preprečimo razmočenje (zmehčanje) proge med zamenjavo navijalnega jedra ali zaustavitvijo navijalnika iz drugih razlogov, je na lepilnem valju razporejena priprava za snetje proge s tega valja. Razen tega se proga z držalnima kovinskima letvama pred lepilno pripravo in za njo pridrži, ko menjamo navijalno jedro.The cardboard line runs from the stock winding through the stock loop to the adhesive roller and from there to the winder. To prevent wetting (softening) of the line while replacing the winding core or stopping the winder for other reasons, a device for removing the line from this roller is arranged on the adhesive roller. In addition, the line with the metal mounting brackets is held in place before the adhesive preparation and held behind when changing the winding core.
Po potrebi lahko porazdeljene po širini proge razporedimo zarezovalne priprave (izdelava plitvih vrezov), če gre za to, da je treba vzporedno izdelovati več objektov, npr. delov za izdelavo naslonov za roke. Nož za prečni odrez navitka loči progo vsakokrat po vnaprej danem številu ovojev.If necessary, notching devices (making shallow cuts) can be arranged along the width of the line if it is necessary to produce several objects in parallel, e.g. parts for making armrests. The cross-sectional cutter of the coil separates the line each time after a pre-determined number of wrappers.
Če je ovito jedro navitka spravljeno v prešo, kar se lahko opravi z dvižnimi in prečnotransportnimi sanmi, ga nato priključimo na napeljavo stisnjenega zraka, tako da jedro ekspandira vse do končnih naslonov v dokončno notranjo obliko. Hkrati pritisna pehala, ki so opremljena s primerno oblikovanimi oblikovnimi deli, z več strani pritiskajo na navitek. Po nekaj sekundah je operacija prešanja končana, oblikovna pehala se krmiljeno vrnejo in navijalno jedro se skrči. Nato se navijalno jedro izvleče in premakne v čakalni položaj do snetja naslednjega navitka, nakar se vpne v navijalno pripravo.If the wrapped core of the winding is pressed, which can be done by lifting and transporting sleighs, then it is connected to the compressed air line so that the core expands all the way to the final backrests in the final internal shape. At the same time, the pressure cups, which are provided with appropriately shaped molded parts, press the reel from several sides. After a few seconds, the quilting operation is complete, the formwork flaps return in a controlled manner and the winding core shrinks. Then, the winding core is pulled out and moved to the waiting position until the next winding is removed, and then clamped into the winding device.
Na navijalnem jedru so predvideni krmilni palci, ki signalizirajo določene kote zavrtitve, da si dovod začetka proge, položaj odrezanega konca proge kot tudi začetek in konec nanašanja lepila in odprtje ležajev za odvzem navitka stalno sledijo v vnaprej danem kotnem položaju. V območju delilnega reza se smotrno ne nanese nikakršno lepilo, da se oblikovni deli ne zlepijo. Začetek proge vsakokrat zgrabimo na navijalnem jedru s prižemalno kovinsko letvijo, ki je krmiljena pnevmatsko s senzorjem.Control rods are provided on the winding core to signal certain angles of rotation that the feed of the beginning of the line, the position of the cut end of the line as well as the beginning and end of the adhesive application and the opening of the bearings for the removal of the coil are constantly followed in a predetermined angular position. It is advisable not to apply any adhesive in the area of the dividing cut to prevent the molded parts from sticking. The start of the track is always grabbed on a winding core with a pneumatic rail, which is pneumatically controlled by a sensor.
Za izdelavo konveksno oblikovanih navitkov je vsakokrat potrebna opremljenost navijalnega jedra z ustrezno oblikovanimi oblikovnimi deli in predvideti je treba opremljenost s komplementarnimi deli zunanjih čeljusti preše. S tovrstno opremo se da narediti podzgradbe za naslone za roke pri oblazinjenih pohištvih, spodnje dele hrbtnih naslonov, spodnje dele sedežev in ležalnikov enostavne zasnove. Na te spodnje dele se da po potrebi namestiti dekorativne in oblikovne kose, npr. v območju naleganja rok prinaslomh za roke, iz penaste snovi.In order to produce convex shaped windings, the winding core must always be equipped with properly shaped molded parts and provision should be made for the complementary parts of the outer jaws of the press. With this kind of equipment, it is possible to make sub-structures for armrests for upholstered furniture, the lower parts of the backrests, the lower parts of the seats and lounges of a simple design. These lower parts can be fitted with decorative and shaped pieces as needed, e.g. foam material in the area of contact with the hands.
Iz podolgem deljenega našitka primerne oblike se da oblikovati naprimer dve lupini za hrbtna naslona, v kateri vložimo blazinski material. Prav tako lahko iz v bistvu pravokotnega navitka oblikujemo dva U kotnika, ki služita vsakokrat kot sedež.It is possible to form, for example, two shells for the backrests in which a cushion material is inserted from an elongated split strip of a suitable shape. It is also possible to form two U angles from a substantially rectangular winding, each serving as a seat.
Udobje sedenja se da povečati, če je sedežna površina luknjana ali opremljena z režami po načinu rešetke iz letev. Luknjanje (prebijanje) se prednostno opravi v nestrjenem stanju, tako da nastane žmulast rob, ki prispeva k togosti.Seating comfort can be increased if the seating surface is punched or fitted with slots according to the lattice grating. The puncturing is preferably done in an uncured state so as to give a bulbous edge which contributes to rigidity.
Ves, iz posameznih delov s skobami spet temeljni okvir (ogrodje) prednostno prevlečemo z blazinsko prevleko, ki je znotraj obšita z blazinskim materialom. Na ta način pridemo s sorazmerno malo vloženega dela do oblikovno lepega, udobnega in stabilnega oblazinjenega pohištva, ki je narejeno iz za okolje sprejemljivega gradiva, ki je v pretežni meri dobljeno z recikliranjem in se ga da spet v celoti reciklirati.In particular, the base frame (frame) is preferably re-coated with the cushion cover, which is inside the cushioned material, from the individual parts with the brackets. In this way, relatively little work is done to create beautifully designed, comfortable and stable upholstered furniture made from environmentally friendly material, which is largely recycled and fully recyclable.
Nadaljnjo prednostno izvedbo pohištvenih surovih delov dosežemo s tem, da ima navijalno jedro ali ločeno pritisno jedro enega ali več izrezov, h katerim je preša komplementarno kosovno opremljena s pritisnimi čeljustmi. Izrez(-a, -i) navijalnega jedra je (sta, so) vsakokrat opremljen(-a, -i) s krmiljeno namestljivo in uvlačljivo oporo, nad katero naredimo navitek.A further preferred embodiment of the crude furniture parts is achieved by having a winding core or a separate pressure core of one or more notches, to which the press is complementary piecewise equipped with pressure jaws. The recess (s) of the winding core (s) are each provided with a controllable adjustable and retractable support over which the winding is made.
Ta opora je lahko naprimer napihljiva gibka cev, ki jo med operacijo prešanja spraznimo. Opora je vsakokrat toliko izpostavljena, da se nad njo napeto območje navitka prilega izrezu, ko preša pritiska v to območje. Na ta način nastanejo konkavne forme, npr. notranja partija sedeža z naslonom oblazinjenega pohištva. Forma v enem kosu pomeni prihranek na delovni operaciji povezovanja, ojačitvenem materialu in s tem tudi na teži.This support may be, for example, an inflatable hose that can be emptied during the pressing operation. The support is always so exposed that the tensioned area of the coil fits above the cutout when the press is pressed into the area. In this way concave forms are formed, e.g. internal seat lot with upholstered furniture. A one-piece form means saving on working bonding operations, reinforcing material and therefore weight.
Če jedro izvlečemo iz navitka neposredno zatem, ko je navitek narejen, in v slednjega vtaknemo primerno zasnovano pritisno jedro, lahko iz navitka, ki se ga še da oblikovati, prešamo kompleksne, konkavne in konveksne forme. Če je pritisno jedro izvedeno krajše od navijalnega jedra, lahko na čelnih straneh navitka posnamemo robove, v kotnih območjih pa namestimo s spodvihanjem (kot pri všitkih pri oblekah) narejene gube. To privede do zelo togih lupin.If the core is removed from the coil immediately after the coil is made and a suitably designed pressure core is inserted into the latter, complex, concave and convex forms can be pressed from the coil which can be formed. If the pressure core is shorter than the winding core, the edges of the winding can be taken off the edges, and wrinkles made in the corner areas can be fitted by underscoring (as in the case of dressing seams). This leads to very rigid shells.
V nadaljnjem se da izdelati dekorativne forme npr. hrbtnih naslonov, ko ozka topa pritisna pehala vtisnejo gube v ozke režaste poglobitve. S tem se da narediti npr. bočne vgreznitve zgornjega roba hrbtnega naslona enako kot preoblikovati gube v tretji dimenziji, pri čemer to preoblikovanje sega čez omejeno preoblikovanje s prešanjem.In the following it is possible to make decorative forms, e.g. backrests when narrow cannon presses inflate folds into narrow slit recesses. This can be done eg. lateral recesses of the upper edge of the backrest in the same way as a wrinkle reshaping in the third dimension, with this reshaping extending beyond a limited recessing.
Nova tehnika izuma je ustvarila visokozgoščen vlakninski laminat (HDF).A new technique of the invention has created a high-density fiber laminate (HDF).
Nadaljnjo nalogo izuma vidimo v ustvaritvi sedežnega in/ali ležalnega elementa, ki bo v zvezi z vitim laminatnim oblikovnim telesom s posebno ureditvijo in zasnovo vzmetnih pramenov in blazinske podlage dosegel optimalno vzmetno in blažilno lastnost in za uporabnika visoko udobje pri sedenju in ležanju, pri čemer ti sestavni deli sami zase kot tudi v medsebojni zvezi omogočajo optimalno recikliranje.It is a further object of the invention to provide a seat and / or bearing element which, in connection with a slender laminate body with a special arrangement and design of the suspension strands and cushion, will achieve optimum spring and soothing properties and provide the user with high comfort in sitting and lying, these components allow for optimum recycling by themselves as well as in interconnection.
Naloga je po izumu rešena z izumiteljskimi značilnostmi iz patentnih zahtevkov 35 do 44.The invention is solved by the inventive features of claims 35 to 44.
Ta sedežni in/ali ležalni element ima kot nosilni del (spodnji okvir/ogrodje) iz zlepljenih plasti iz kartona, papirja, vlakninskih snovi ali podobnega narejeno in oblikovano laminatno oblikovno telo, ki ima samo po sebi visoko stabilnost, pa kljub temu določeno vzmetno lastnost. Na to laminatno oblikovno telo so posredno preko pramenov vezanega penastega gradiva razporejene peresne lesene letve in kovinsko vzmetno jedro in/ali blazinska podlaga iz penastega gradiva, in vsi sestavni deli elementa so povezani z lepljenjem.This seat and / or bearing member has, as a supporting member (lower frame / frame), of glued layers of cardboard, paper, fibrous matter or the like, a laminated laminate body which has inherently high stability, yet has a certain spring-like property. . To this laminate body, plywood foam laths and a metal spring core and / or foam pad are indirectly spread over the strands of the foam-bound material, and all the components of the element are bonded.
Vzmetno jedro s peresnimi lesenimi letvami in posredno preko pramenov vezanega gradiva privede po eni strani do zelo dobre vzmetne in blažilne lastnosti, čez laminatno oblikovno telo čelno in hrbtno štrleča blazinska podlaga iz penaste snovi pa za sedežno in/ali ležalno površino pred vzmetnim jedrom in za njim oz. peresnimi lesenimi letvami privede do mehkejših blazinskih območij, tako da ta tri vzmetna območja za uporabnika nudijo zelo visoko udobje pri sedenju in ležanju in sedežna ter ležalna površina se ugodno prilagodi vsakokratnemu položaju uporabnika.A spring core with feather wooden slats and indirectly through strands of bound material results in very good spring and shock absorbing properties, and a foam material front and back protruding foam material over the laminate body behind the seat and / or bearing surface in front of the spring core and behind him or. the wooden planks lead to softer cushioning areas, so that these three spring zones provide the user with very high comfort when sitting and lying down, and the seating and lying surface adapts favorably to the individual position of the user.
Zaradi izbora gradiv za sestavne dele in lepilno zvezo je sedežni in/ali ležalni element kot celota vse do kovinskega vzmetnega jedra primeren za recikliranje. Razen tega lahko podlago iz penaste snovi naredimo eno- ali večplastno v raznih trdotah, kar še dodatno vpliva na vzmetenje in blažitev sedežne in/ali ležalne površine.Due to the selection of materials for components and adhesive bonding, the seat and / or bearing element as a whole down to the metal spring core is suitable for recycling. In addition, the foam base can be made single or multi-layered in various hardnesses, which further affects the suspension and damping of the seat and / or bearing surface.
Tovrstne elemente se da na enostaven način sestavljati v daljša ali tudi čez kot razporejena sedežna in/ali ležalna pohištva.Such elements can be easily assembled into longer or longer than seated and / or recumbent furniture.
Nadaljnja prednost sedežnega in/ali ležalnega elementa je na osnovi laminatnega oblikovnega telesa in posameznih elementov za blazino in vzmetenje v majhni teži, pa vendarle veliki stabilnosti.A further advantage of the seat and / or bearing element is that it is based on the laminate body and individual cushion and suspension elements in light weight, yet high stability.

Sl. 1 kaže potek postopka za izdelavo sestavnih delov pohištva. Ta v svojih osrednjih korakih sestoji iz nanašanja lepila (LA) lepila (LE) na karton (K), navijanja (WI) kartonske proge (KB), prešanja (PR) navitka (W), odstranitve jedra (EK) iz le-tega kot tudi razformanja in strditve (AH) le-tega. Poleg tega v danem primeru nastopa pri prešanju (PR) še perforiranje (PF) in/ali kosovno opremljanje (BS) navitka (W) s sidri, zatiči, vijačnimi vložki (SE) ipd. Nadalje lahko že pred strjevanjem (AH) sledi vlaganje (ES) in vključevanje prečk (ST) kot tudi zlepljanje (LV) in priključevanje krovnih plošč (DP) na navitek (W).FIG. 1 shows the process for the manufacture of furniture components. In its central steps, it consists of applying glue (LA) glue (LE) to cardboard (K), winding (WI) cardboard line (KB), pressing (PR) winding (W), removing the core (EC) from it as well as the decomposition and solidification (AH) thereof. In addition, perforation (PF) and / or piecewise fitting (BS) of the winding (W) with anchors, pins, screw inserts (SE) and the like occurs in a given case in the case in question. Furthermore, pre-curing (AH) may be preceded by insertion (ES) and inclusion of cross bars (ST) as well as adhesion (LV) and connection of decking boards (DP) to the coil (W).
Navitek (W) smotrno po strditvi (AH) razdelimo v delilni operaciji (TS) v danem primeru na več delov (Wl, W2). Nadalje lahko sledi vrezovanje (85) z izžagovanjem narejenih režnih vrezov ipd. Navitek (W) lahko alternativno v prvi operaciji snemanja jedra (EK1) snamemo in nataknemo na ločeno jedro za prešanje.The coil (W) is expediently divided after the hardening (AH) in the dividing operation (TS) into a given case into several parts (Wl, W2). Further, the incision (85) may be followed by the burning of the incised slots, etc. Alternatively, in the first core recording operation (EK1), the coil (W) can be removed and loaded onto a separate quilting core.
Sl. 2 kaže shematizirano navijalno pripravo v prerezu. Karton (K) odvijamo kot kartonsko progo (KB) z zalogovnega navitka (R) in ga vodimo preko napenjevalnika (1) proge, ki slednji stalno podeljuje prednapetje preko cilindra (10) na stisnjen zrak, pri mirovanju navijalnika pa tvori zalogovno zanko, dokler zalogovni navitek (R), krmiljen od nastajanja zanke, ne obmiruje. Tudi zaradi v splošnem neokroglega obrisa navitka (W) nastajajo pri konstantni vrtilni hitrosti nihanja v dolžini proste kartonske proge (KB), ki jih pobere napenjalnik (1) proge, ne da bi morali zalogovni navitek (R) pospeševati in zavirati. Dodatno je navijalnik (4) držan na nihalnih rokah (93), katerih nihalni pogon (94) ima dolžinsko izravnavo.FIG. 2 shows a schematic cross-sectional view of the winding device. The cardboard (K) is unwound as a cardboard line (KB) from the stock winder (R) and is guided through the tensioner (1) of the line, which continuously distributes the prestressing through the cylinder (10) to compressed air and forms a stock loop when the winder is stationary. the stock reel (R) controlled from loop formation does not rest. Also, due to the generally non-circular contour of the coil (W), it produces at constant rotational speeds oscillations in the length of the free cardboard line (KB) picked up by the line tensioner (1) without having to accelerate and decelerate the stock coil (R). Additionally, the retractor (4) is held on the swing arms (93), whose swing drive (94) has a length offset.
Kartonska proga (KB) je vodena preko več preusmernih valjev (11 do 15), od katerih prvi in zadnji sodelujeta z držalnima letvama (21, 25), ki se ju da krmiliti in ki kartonsko progo (KB) zgrabita, ko navijalnega jedra (4) ne vrtimo. Med dvema od preusmernih valjev (14, 15) je razporejen valj (3) za nanos lepila, ki se spodaj potaplja v lepilno kopel (30) in mimo katerega - ob tem, ko se on vrti - drsi rakel (strgalo) (31), nakar valj (3) zgoraj oblepi (opremi z lepilom) kartonsko progo (KB).The cardboard line (KB) is guided by several rollers (11 to 15), the first and the last of which interact with the controllable holders (21, 25) and which grab the cardboard line (KB) when the winding core ( 4) we don’t spin. Between the two rollers (14, 15) is arranged a roller (3) for applying adhesive, which is immersed below into the adhesive bath (30) and past which, while rotating, slides the rake (scraper) (31). , then roll (3) the cardboard line (KB) above (attach with glue).
Smer in hitrost vrtenja valja (3) za nanašanje lepila v bistvu ustreza onima od kartonske proge (KB). V ta namen je na valj (3) priključen pogon (32) valja, ki se ga da preko postavljalnega prenosnika krmiliti in ki svoj hotenostni signal (signal naj) dobi od na dotočni strani ležečega preusmernega valja (14). Alternativno je predviden počasen pogon s prostim tekom, ki omogoča sotek s progo. Oba na dotočni strani valja (3) za nanašanje lepila ležeča preusmerna valja (13, 14) sta povezana z dvižno pripravo (33), ki pri mirujoči kartonski progi (KB) le-to dvigne od valja (3). Pri tem pogon (32) valja še naprej deluje s prejšnjo vrtilno hitrostjo, kar preprečuje prisušitev lepila na prosti površini.The direction and speed of rotation of the adhesive roller (3) essentially corresponds to that of the cardboard line (KB). For this purpose, a cylinder drive (32) is connected to the cylinder (3), which can be controlled via a set-up laptop and which receives its desired signal (signal) from the downstream side of the diversion cylinder (14). Alternatively, a slow idle drive is provided to allow for collision with the line. Both on the inlet side of the adhesive roller (3), the roller rollers (13, 14) are connected to a lifting device (33) which, when the cardboard line (KB) is stationary, lifts it away from the roller (3). The cylinder drive (32) continues to operate at the previous rotational speed, which prevents the adhesive from drying on the free surface.
Lepilno kopel (30) držimo - krmiljeno z merilnikom (36) gladine in merilnikom (37) viskoznosti - stalno pri stanju gladine na vnaprej dani višini s pomočjo krmiljenega dolivanja, viskoznost pa stalno preizkušamo in jo z dodajanjem porabljene tekočine stabiliziramo. Vsebnik (34) lepilne kopeli je razporejen na dvižni pripravi (35), tako da ga za potrebe čiščenja lahko spustimo niže.The adhesive bath (30) is kept - controlled by the level gauge (36) and the viscosity gauge (37) - constantly at the level at a predetermined height by means of controlled topping, and the viscosity is constantly tested and stabilized by adding the consumed liquid. The container (34) of the adhesive bath is arranged on the lifting device (35) so that it can be lowered for cleaning purposes.
Pripravi za oblepljanje sledi navijalno jedro (4) s pogonom (42) navijalnega jedra.

Oba jedrna kosa (40, 41) sta preko pnevmatsko vodenega ekscentra (43) pritiskana narazen in sta z vzmetema vlečena skupaj. Oba osna ležaja (44) navijalnega jedra (4) sta deljena in se ju odpira pnevmatsko krmiljeno, tako daje navitek (W) z jedrom navitka snemljiv in se ga transportira v prešo. Pogon (42) jedra navitka se nahaja med dvojnim ležajem (92), ki omogoča prosto nošenje jedra (4) z navtkom (W), tako da se da po odvihtitvi ležaja (1) na drugem koncu jedra navitka tam navitek (W) sneti, čemur služi priprava (90) za snemanje navitka. Ležaja (91, 92) jedra navitka sta zavihtljiva okoli skupne osi (95), tako da nihalni pogon (96) kartonske proge (KB) pri konstantni kotni hitrosti izvaja konstanten vlek in z enakim pomikom.The bonding device is followed by a winding core (4) with a drive (42) of the winding core. The winding core (4) consists of two mutually held core pieces (40, 41) provided with interchangeable molded parts (Fl to F4), the outside of which rests on the inner surface of the winding (W). Both core pieces (40, 41) are pressed apart via a pneumatically driven eccentric (43) and are pulled together by springs. Both axle bearings (44) of the winding core (4) are split and are opened pneumatically controlled so that the winding (W) with the winding core is detachable and transported to the press. The drive (42) of the winding core is located between a double bearing (92) which allows the core (4) to be carried freely with the winding nut (W) so that, after swiveling the bearing (1) at the other end of the winding core, the winding (W) can be removed there. , which is used by the device (90) for recording the winding. The bearings (91, 92) of the winding core are rotatable about a common axis (95) such that the pendulum drive (96) of the cardboard track (KB) performs a constant pull and with equal displacement at constant angular speed.
Pred jedrom (4) navitka je razporejen prečni rezalnik (45), na katerega nosilcu tekoče proge je kartonska proga (KB) s sesalnimi posodicami (46) držana od zgoraj, medtem ko gotovi navitek (W) odstranjujemo, vse do namestitve svežega navijalnega jedra (4). Razen tega so na nosilcu rezalnega sklopa bočno premično in pritrdljivo nataknjeni zarezovalni noži (47), ki jih je moč krmiliti in ki služijo vzdolžnemu paranju kartonske proge (KB), ko vzporedno izdelujemo več delov. Do krmiljenja prečnega rezalnika (45), držalnih letev (21, 25), sesalnih posodic (46) in dvigalne priprave (33) pride preko nastavljivih krmilnih palcev (42) na osi jedra navitka v povezavi s števcem (49) ovojev.In front of the core (4) of the winding is arranged a cross cutter (45), on which the carrier of the liquid line is a cardboard line (KB) with suction cups (46) held from above, while the finished winding (W) is removed until the fresh winding core is installed (4). In addition, there are laterally movable and lockable, adjustable-cut cutting blades (47) on the cutting unit bracket that serve to longitudinally tear the cardboard line (KB) when several parts are being made in parallel. The control of the cross cutter (45), the holding strips (21, 25), the suction cups (46) and the lifting device (33) is via adjustable control thumbs (42) on the axis of the core of the coil in conjunction with the counter (49) of the wrappers.
