Fremgangsmåte og anordning ved ekstrudering av kunststoffslanger for senere blåseforming eller vakuumforming. Procedure and device for extruding plastic hoses for subsequent blow molding or vacuum forming.

fremgangsmåte og anordning til bruk ved method and device for use by

tilknytning til blåse- eller vakuumforming. connection to blow or vacuum forming.
Ved blåseforming eller vakuumforming By blow molding or vacuum forming
anvendes det som utgangsmateriale slanger som ekstruderes og ved hjelp av trykk-luft eller vakuum formes i en eller flere hoses are used as starting material which are extruded and formed into one or more using compressed air or vacuum
former. OBlåseformene plasseres umiddel-bart etter ekstruderen, slik at formingen forms. The OBlock forms are placed immediately after the extruder, so that the forming
foregår mens plasten ennå er varm og takes place while the plastic is still warm and

For å råde bot på denne ulempe ville To remedy this inconvenience would
det vært rimelig å tenke på en horisontal it would have been reasonable to think about a horizontal one
ekstrudering av slange for dette formål. extrusion of hose for this purpose.
Horisontal ekstrudering både av slange og Horizontal extrusion of both hose and
andre emner er jo alminnelig kjent, men other subjects are of course generally known, but
man har da en nedkjøling av plasten rett utenfor, ekstruderdysen. Som tidligere nevnt vil man imidlertid beholde plasten i sin varme og formbare tilstand helt til emnet dekker åpningen for formene. Her oppstår det et alvorlig problem. dersom en slange på normal måte blir- ekstrudert i horisontal retning. En relativt tynnvegget slange er nemlig ikke selvbærende i denne tilstand og vil folde seg sammen dersom formen har en viss utstrekning i lengde-retningen. you then have a cooling of the plastic right outside, the extruder nozzle. As previously mentioned, however, the plastic will be kept in its warm and malleable state until the blank covers the opening for the molds. A serious problem arises here. if a hose is normally extruded in a horizontal direction. A relatively thin-walled hose is not self-supporting in this state and will fold up if the shape has a certain extent in the longitudinal direction.
Foreliggende oppfinnelse tar derfor sikte på en fremgangsmåte og anordnin-ger som eliminerer dette problem slik at man med meget enkle foranstaltninger kan ekstrudere slanger selv med meget stor diameter og tynn veggtykkelse uten at det oppstår de tidligere omtalte ulemper. The present invention therefore aims at a method and devices which eliminate this problem so that with very simple measures, hoses can be extruded even with a very large diameter and thin wall thickness without the previously mentioned disadvantages occurring.
Dette oppnås ifølge oppfinnelse ved at slangen som på i og for seg kjent måte ekstruderes i horisontal eller i det vesentlige horisontal retning, føres fra ekstruderen ved hjelp av et bæreorgan som består av en eller flere stenger som eventuelt kan benyttes ved utstrekning av slangen på tvers av dens lengderetning. Den i horisontal retning ekstruderte slange henger i eller over dette organ. Det vil derved skje en uttynning av slangens øvre del, altså den del som ligger i kontakt med bæreorganet. Denne uttynning kan lett kom-penseres ved at slangens gods ved en jus-tering av ringdysen ekstruderes tykkere i dette området. This is achieved according to the invention by the hose, which is extruded in a horizontal or substantially horizontal direction in a manner known per se, being guided from the extruder by means of a carrier which consists of one or more rods which can possibly be used when stretching the hose across of its longitudinal direction. The horizontally extruded hose hangs in or above this body. This will result in a thinning of the upper part of the hose, i.e. the part that is in contact with the carrier. This thinning can easily be compensated by the hose material being extruded thicker in this area by adjusting the ring nozzle.
