Claims (11)
1. Fremgangsmåde til at danne imitationsgrene (1), hvor en polymermasse omfattende et ekspanderbart plast smeltes under tryk i en første ekstruder for at danne en første blanding, derefter drives igennem et ekstruderingshoved (2) og trækkes fra dette ekstruderingshoved (2) i formen af en plaststreng (3), hvorved fremgangsmåden yderligere omfatter de følgende trin: - blanding af mindst en mængde af partikler omfattende plantefibre med mindst en mængde af polymer i en anden ekstruder for at danne en anden blanding; - i nævnte ekstruderingshoved (2) den simultane ekstrudering af den dannede anden blanding med den første blanding således at polymeren mindst delvist omgiver de nævnte partikler; hvorved, på baggrund af den dannede anden blanding, et første lag (4) dannes på plaststrengen (3), hvilket første lag skal mindst delvist dække yderfladen af denne plaststreng (3).
2. Fremgangsmåde til at danne imitationsgrene (1) ifølge krav 1, kendetegnet ved, at plaststrengen (3) forsynes med mindst det første lag (4), efterfølgende køles og afkortes til den ønskede længde, hvor plaststrengen (3) under køling mindst delvist trækkes igennem et bevægende kølemedium (4), hvorved plaststrengen (3), over mindst en del af sin vej igennem kølemediet (4), fuldkommen nedsænkes i dette kølemedium (4).
3. Fremgangsmåde ifølge krav 2, kendetegnet ved, at, under køling, gasbobler tilvejebringes på mindst en del af yderfladen af plaststrengen (3), hvilke gasbobler ved irregulære placeringer isolerer overfladen af plaststrengen (3) fra kølemediet (4), hvorved plaststrengen (3) på sin yderflade mindst delvist forsynes med ændringer i overfladestrukturen.
4. Fremgangsmåde ifølge krav 2 eller 3, kendetegnet ved, at det nævnte kølemedium er vand og ved, at de nævnte gasbobler er luft- og/eller nitrogenbobler.
5. Fremgangsmåde til at danne imitationsgrene (1) ifølge et af de foregående krav, kendetegnet ved, at de nævnte plantefibre er træfibre.
6. Fremgangsmåde til at danne imitationsgrene (1) ifølge et af de foregående krav, kendetegnet ved, at den dannede plaststreng (3) er af rørformet konstruktion.
7. Fremgangsmåde til at danne imitationsgrene (1) ifølge et af de foregående krav, kendetegnet ved, at fremgangsmåden yderligere omfatter de følgende trin: - blanding af mindst en mængde af polymer med mindst en mængde af additiv for at danne en tredje blanding; - coekstruderingen af den dannede tredje blanding med den anden blanding; hvorved, på baggrund af den dannede tredje blanding, et andet lag tilvejebringes på mindst en del af det første lag (4).
8. Fremgangsmåde til at danne imitationsgrene (1) ifølge et af de foregående krav, kendetegnet ved, at, på niveauet af ekstruderingshovedudløbet, hastigheden ved hvilken polymermassen drives igennem ekstruderingshovedet (2) er gensidigt forskelligt på de forskellige sider af ekstruderingshovedudløbet.
9. Imitationsgren (1), omfattende en plaststreng (3) fremstillet af et ekspanderbart plast, hvor den nævnte plaststreng (3), over mindst en del af sin yderflade, er forsynet med et første lag (4) der er forbundet til plaststrengen (3) ved hjælp af coekstrudering, hvor dette første lag fremstilles af et kompositmateriale bestående af: - en mængde af partikler omfattende plantefibre; - en mængde af polymer, hvor denne polymer mindst delvist omgiver de nævnte partikler.
10. Vægplade omfattende et antal af imitationsgrene (1) ifølge krav 9 eller omfattende et antal af imitationsgrene fremstillet efter en fremgangsmåde beskrevet i et af kravene 1 til 8
11. Vægstruktur omfattende en vægplade ifølge krav 10, hvor den nævnte vægstruktur omfatter en metal- eller træramme mellem hvilken eller mod hvilken væg pladen er monteret.
