Description
Oppfinnelsen vedrører en innretning til fremstilling av muffer på viklingsrør med en som viklingsdor tjenende trommel, hvis viklingsdiameter i området ved muffene kan økes ved hjelp av på trommelen anbringbare og med denne bevegbare anlegg, og med en tilføring for tilførsel av et profilbånd av termoplastisk kunststoff på trommelen. The invention relates to a device for producing sleeves on winding pipes with a drum serving as a winding mandrel, the winding diameter of which in the area of the sleeves can be increased by means of devices that can be placed on the drum and which can be moved with it, and with a supply for supplying a profile band of thermoplastic plastic on the drum.
Ved en kjent fremgangsmåte og tilhørende innretning til fremstilling av viklingsrør, ved hvilken kunststoffbånd vikles skruelinjeformet om en stillestående dor, blir det til fremstilling av en dobbeltmuffe under rørfremstillingen skjø-vet en til muffens indre kontur svarende ring over doren. Båndene blir så viklet kontinuerlig videre over ringen, som etter avtrekningen av det ferdige rør fra doren og oppdeling av røret igjen kan fjernes. In a known method and associated device for the production of winding pipes, in which plastic tape is wound helically around a stationary mandrel, a ring corresponding to the inner contour of the sleeve is pushed over the mandrel to produce a double sleeve during the production of the tube. The bands are then wound continuously over the ring, which can be removed after pulling the finished tube from the mandrel and dividing the tube again.
Ufordelaktig ved denne kjente fremgangsmåte for til-forming av muffer under rørfremstillingen er at det må anord-nes forskjellige muffeformringer i samsvar med viklingsdiameteren og muffeutformingen. A disadvantage of this known method for forming sleeves during pipe production is that different sleeve formations must be provided in accordance with the winding diameter and the sleeve design.
Den oppgave som ligger til grunn for oppfinnelsen The task underlying the invention
er å tilveiebringe en innretning til fremstilling av muffer, hvilken innretning lett og med lite arbeide kan tilpasses til de forskjellige rørdimensjoner og viklingsbetingelser. is to provide a device for the production of sleeves, which device can easily and with little work be adapted to the different pipe dimensions and winding conditions.
Ifølge oppfinnelsen blir dette oppnådd ved en innretning av den innledningsvis nevnte type ved at anleggene for økning av viklingsdiameteren for trommelen i området ved muffene består hver gang av et på trommelen påviklbart, ved sine to ender i bredde og tykkelse avsmalnende bånd som sammen med profilbåndet kan tilføres til trommelen på dets mot trommelen vendte side. According to the invention, this is achieved by a device of the type mentioned at the outset in that the facilities for increasing the winding diameter of the drum in the area of the sleeves each time consist of a tape that can be wound on the drum, tapering at its two ends in width and thickness, which together with the profile tape can is supplied to the drum on its side facing the drum.
Innretningen ifølge oppfinnelsen muliggjør fremstill-ingen av kontinuerlige rør med muffer, også dobbeltmuffer, i vilkårlige størrelser ved hjelp av viklingsmetoden. The device according to the invention enables the production of continuous pipes with sleeves, also double sleeves, in arbitrary sizes by means of the winding method.
Innretningen ifølge oppfinnelsen er skjematisk vist The device according to the invention is schematically shown
på tegningen (fig. 1 og 2) i form av et utførelseseksempel og skal i det følgende nærmere forklares ved hjelp av dette. on the drawing (fig. 1 and 2) in the form of an example of execution and shall be further explained with the help of this in the following.
På en roterende trommel 1 påføres et profilbånd 5 A profile band 5 is applied to a rotating drum 1
av termoplastisk kunststoff, f. eks. PVC, hvorved pressruller 4 tilveiebringer det nødvendige forbindelsestrykk på profil-båndkantene. of thermoplastic plastic, e.g. PVC, whereby pressing rollers 4 provide the necessary connection pressure on the profile strip edges.
Pressrullene 4 er anordnet ettergivende, henholdsvis innstillbare i radiell retning, slik at de kan innstilles syn- The press rollers 4 are arranged yielding, respectively adjustable in the radial direction, so that they can be adjusted vis-
kront med forandringen av viklingsdiameteren. Derved er hen-siktsmessig anordnet en tilsvarende styring som sikrer et jevnt presstrykk. crowned with the change of the winding diameter. Thereby, a corresponding control is appropriately arranged which ensures an even pressing pressure.
Sammen med profilbåndet 5 pålegges et ved sin fremre Together with the profile band 5, one is applied at its front
og bakre ende avsmalnende viklingsbånd 6 på trommelen 1, og dette legges mellom trommelen og profilbåndet 5, hvorved viklingsdiameteren etter påleggingen av en avsmalnet viklings-båndsbegynnelse 3 økes tilsvarende, og det tilveiebringes en muffelignende utvidet rørdel 2. På analog måte blir etter gjennomgang av den avsmalnede viklingsbåndende viklingsdiamete- and rear end tapering winding band 6 on the drum 1, and this is placed between the drum and the profile band 5, whereby the winding diameter after the application of a tapered winding band beginning 3 is increased accordingly, and a sleeve-like extended pipe part 2 is provided. In an analogous way, after reviewing the tapered winding banding winding diameters
ren igjen redusert til sin opprinnelige størrelse. clean again reduced to its original size.
Det skal forstås at viklingsbåndet 6 pålegges på trommelen 1 sammen med profilbåndet 5 ved det tidspunkt som muffen skal fremstilles. Lengden til viklingsbåndet 6, som kan være et metallbånd, leddbånd eller fiberbånd, retter seg etter rørdiameteren og den ønskede muffelengde. It should be understood that the winding band 6 is placed on the drum 1 together with the profile band 5 at the time when the sleeve is to be manufactured. The length of the winding band 6, which can be a metal band, joint band or fiber band, depends on the pipe diameter and the desired sleeve length.
Etter oppdelingen av det avkjølte rør som fjernes After the division of the cooled tube that is removed
fra trommelen 1 i midten av muffestykket kan viklingsbåndet 6 from the drum 1 in the middle of the sleeve piece, the winding tape 6
igjen tas av og tilføres til fornyet anvendelse. again removed and added for renewed use.
