FREMGANGSMÅTE TIL FREMSTILLING AV LAMELLVIRKE ELLERPROCEDURE FOR THE MANUFACTURE OF LAMINATED WIRE OR
LAMELLPROFILER.LAMINAL PROFILES.
Foreliggende oppfinnelse angår en fremgangsmåte til fremstilling av lamellvirke eller lamellprofiler. The present invention relates to a method for producing slatted wood or slatted profiles.
Ved fremstilling av lamellvirke har man tidligere limt sammen to eller flere lag av relativt lange, sagede og høvlede virkestykker. Ved variasjon av dimensjonene har man også fremstilt lamellprofiler. Utgangsmaterialet har imidler-tid vært av jevn god kvalitet. In the production of laminated timber, two or more layers of relatively long, sawn and planed timber pieces have previously been glued together. By varying the dimensions, lamella profiles have also been produced. The starting material has, however, been of consistently good quality.
Ifølge foreliggende oppfinnelse har man nuAccording to the present invention, one now has
funnet at det er mulig også å utnytte virke av meget lav kvalitet for fremstilling av lamellvirke eller lamellprofiler, dersom fremstillingen skjer på en bestemt måte. Denne måte kjennetegnes ifølge oppfinnelsen av at man på en pfimærlist av prima virke pålegger to eller flere sjikt av biter som er utsaget av virke av sekundær kvalitet, idet biter tilhørende et og samme sjikt sammenføyes ved stumpskjøting og de forskjellige sjiktene føyes til grunnlisten resp. inntilliggende sjikt ved langsgående fingerskjøting. found that it is also possible to use timber of very low quality for the production of laminated timber or laminated profiles, if the production takes place in a specific way. According to the invention, this method is characterized by applying two or more layers of pieces of wood of secondary quality to a pfimær strip of prime wood, with pieces belonging to one and the same layer being joined by butt jointing and the different layers being added to the base strip or adjacent layer by longitudinal finger jointing.
Ifølge oppfinnelsen oppbygges således lamellvirket av et første sjikt av virke av høy kvalitet, som dersom det skjøtes Bør fingerskjøtes. På dette sjiktet bygger man opp minst to sjikt av virkestykket av varierende lengde. For disse sjiktene utnytter man virke av meget lav kvalitet og sager bort kvister og andre feil. De godtagbare virkestykkene som da opp-nås har ifølge tidligere teknikk vært for korte til å kunne finne anvendelse. Ved at man legger dem ut etterhverandre i flere sjikt har det vist seg at man gjennom den tilfeldige for-delingen av skjøtene overlappes en skjøt i det nedre sjiktet av biten ovenfor, hvor styrken ble meget god, selvom bitene i de øvre sjiktene stumpskjøtes ende mot ende. According to the invention, the slatted timber is thus built up from a first layer of high-quality timber, which, if joined, should be finger-jointed. At least two layers of the workpiece of varying length are built up on this layer. For these layers, wood of very low quality is used and twigs and other defects are sawed away. According to prior art, the acceptable working pieces that are then achieved have been too short to find application. By laying them out one after the other in several layers, it has been shown that, through the random distribution of the joints, a joint in the lower layer is overlapped by the piece above, where the strength was very good, even though the pieces in the upper layers are butt-jointed end towards end.
Sammenføyningen av sjiktene skjer ved at man først, freser eller høvler ut en tannprofil på de mothverandre beliggende sidene. Øverst på tennene stry.kes et tynt limlag. Bitene legges sammen og lamellvirket kjøres inn i en valsepresse hvorved man samtidig trykker frem de øvressjiktene, The layers are joined together by first milling or planing out a tooth profile on the opposite sides. A thin layer of glue is applied to the top of the teeth. The pieces are put together and the lamella is driven into a roller press, whereby the upper layers are simultaneously pressed forward,
slik at bitene ende mot ende. Pressingen skjer under høyt trykk, men uten varme, noe som muliggjør høy kapasitet. Da det ikke trenges oppvarming er metoden også energisparende. so that the pieces end to end. The pressing takes place under high pressure, but without heat, which enables a high capacity. As no heating is needed, the method is also energy-saving.
Etter pressingen gir sammenholdingen mellom tennene lamellvirket en slik styrke at det kan håndteres og lagres før limet er herdet. After pressing, the cohesion between the teeth gives the lamella structure such strength that it can be handled and stored before the glue has hardened.
Oppfinnelsen skal i det følgende forklaresThe invention will be explained below
nærmere under henvisning til tegningen som viser et eksempel på fremstillingen ifølge oppfinnelsen av sprosser for vinduer. in more detail with reference to the drawing which shows an example of the production according to the invention of bars for windows.
Fig. 1 viser de forskjellige virkesdelene før sammenføyning, Fig. 1 shows the different working parts before joining,
fig. 2 viser virkesdelene etter sammenføyning, pressing og saging i to deler, og fig. 2 shows the working parts after joining, pressing and sawing into two parts, and
fig. 3 viser to ferdige sprosser.fig. 3 shows two finished bars.
For fremstilling av sprosser for vinduer benyttes vanligvis bare prima kvistfritt virke av høyeste kvalitet. Ved fremstillingen ifølge oppfinnelsen utgår man fra et tørket virke av dimensjonene 125 x 25 mm av høyeste kvalitet, som finger-skjøtes, fingerhøvles i sin lengderetning på den ene siden og føres frem til en monteringsstasjon for å tjenestegjøre som primærlist i lamellvirket (virkestykke 1 i fig. 1). Tørket virke av dimensjonen 42 x 19 mm av sjette, kvalitet deles opp på to fingerhøvler, den ene for langsgående fingerhøvling på begge sider og den andre for tilsvarende høvling bare på en side. Etter høvling går virket til en sorteringskapper, der kvister og andre skader sages bort. De godtatte bitene belegges med lim og føres videre til monteringsstasjonen der det på virkestykket 1 bygges opp to strenger som hver består av et lag av på begge sider fingerhøvlede biter 2 nærmest virkets stykke 1, og ovenpå dette et sjikt av på bare den ene siden fingerhøvlede biter 3. Den således oppbyggede lamellprofil føres gjennom en valsepresse der sjiktene presses sammen. Straks etter pressingen sages lamellene opp i to forskjellige deler 4 (fig. 2), som i en pro-filhøvel høvles opp til to sprosser 5 (fig. 3). Disse føres til en kappestasjon der de kappes opp i ønskede lengder. Disse lagres inntil limet er herdet hvoretter de sendes ut til kundene. For the manufacture of window bars, only prime knot-free timber of the highest quality is usually used. In the production according to the invention, one starts from a dried timber of the dimensions 125 x 25 mm of the highest quality, which is finger-jointed, finger planed in its longitudinal direction on one side and brought to an assembly station to serve as the primary strip in the slatted timber (piece of timber 1 in Fig. 1). Dried work of the dimension 42 x 19 mm of sixth, quality is divided into two finger planers, one for longitudinal finger planing on both sides and the other for corresponding planing only on one side. After planing, the wood goes to a sorting machine, where twigs and other damage are sawed away. The accepted pieces are coated with glue and taken further to the assembly station where two strings are built up on the work piece 1, each consisting of a layer of finger-planed pieces 2 on both sides closest to the work piece 1, and on top of this a layer of finger-planed on only one side bits 3. The lamellar profile thus constructed is passed through a roller press where the layers are pressed together. Immediately after pressing, the slats are sawn into two different parts 4 (fig. 2), which are planed in a profile planer into two slats 5 (fig. 3). These are taken to a cutting station where they are cut into desired lengths. These are stored until the glue has hardened, after which they are sent out to customers.
Den frembragte sprossens styrke er meget god og verdien på det i sprossen benyttede virket av kvalitets6 er øket til den 10-dobbelte. The strength of the bars produced is very good and the value of the work of quality 6 used in the bars has been increased to 10-fold.
