Description
Fremgangsmåte til anbringelse av et plastbelegg på et legeme. Method for placing a plastic coating on a body.
.Foreliggende oppfinnelse angår en .The present invention relates to a
fremgangsmåte til anbringelse av et plastbelegg på et legeme. method for placing a plastic coating on a body.
Det er kjent en slik fremgangsmåte Such a method is known
hvor en plasthylse utvides ved tilførsel av where a plastic sleeve is expanded by the supply of
trykkluft inne i hylsen, i hvilken en list skal compressed air inside the sleeve, in which a strip should
tres inn. Det sier seg selv at det er proble-matisk å skyve listen inn mot trykket i threaded in. It goes without saying that it is problematic to push the list in against the print
hylsen og samtidig motvirke friksjonen i the sleeve and at the same time counteract the friction in
den tetning som er nødvendig mellom hylsen og listen. the seal required between the sleeve and the strip.
Hensikten med oppfinnelsen er å unn-gå denne ulempe og tilveiebringe en fremgangsmåte av ovenfor nevnte art, hvorved The purpose of the invention is to avoid this disadvantage and to provide a method of the above-mentioned type, whereby
plastbelegget kan anbringes på enkel og the plastic coating can be placed on simple and
sikker måte. safe way.
Dette oppnås ifølge oppfinnelsen ved at This is achieved according to the invention by
en plastslange med tilnærmet samme tverrsnittsdimensjoner som legmet gjøres myk a plastic hose with approximately the same cross-sectional dimensions as the body is softened
ved oppvarming og føres inn i et kammer by heating and is fed into a chamber
hvis lengde tilnærmet tilsvarer lengden av whose length approximately corresponds to the length of
legemet og hvis innvendige tverrsnittsdimensjoner er noe større enn plastslangens the body and whose internal cross-sectional dimensions are somewhat larger than those of the plastic hose
ytre tverrsnittsdimensjoner, idet kammerets mot slangen vendende vegg er forsynt outer cross-sectional dimensions, as the wall of the chamber facing the hose is provided
med en mengde små åpninger som står i with a multitude of small openings that stand in
forbindelse med en kilde som leverer undertrykk, slik at den myke plastslange suges connection with a source that delivers negative pressure, so that the soft plastic hose is sucked
inn til kammerets vegger, hvoretter legemet føres inn i den del av plastslangen into the walls of the chamber, after which the body is introduced into that part of the plastic hose
som befinner seg i kammeret, og undertrykket fjernes, hvoretter slangen eventuelt kappes av utenfor kammeret og det which is in the chamber, and the negative pressure is removed, after which the hose is possibly cut off outside the chamber and it
plastbelagte legeme fjernes fra kammeret. plastic coated body is removed from the chamber.
På denne måte vil den utvidede slanges In this way, it will be extended
indre stå til fri rådighet for plassering av interior stand freely available for placement of
legemet uten hinder av noe slag. the body without hindrance of any kind.
Ved at slangen ikke utvides mere enn In that the hose does not expand more than
strengt tatt nødvendig for å føre legemet inn, mister ikke plasten sin avstivende virkning på legemet. strictly necessary to bring the body in, the plastic does not lose its stiffening effect on the body.
Fremgangsmåten er særlig egnet for plastbelegning av skaft og håndtak, f. eks. av tre eller metallrør, og oppvarmingen av plastslangen skjer fortrinnsvis ved at denne føres gjennom et varmt vannbad. Kammeret omgis fortrinnsvis med en kappe som står i forbindelse med en kilde som leverer undertrykk, f. eks. en melkemaskin. The procedure is particularly suitable for plastic coating of shafts and handles, e.g. of wood or metal pipes, and the plastic hose is preferably heated by passing it through a hot water bath. The chamber is preferably surrounded by a jacket which is connected to a source which supplies negative pressure, e.g. a milk machine.
En anordning for utførelse av fremgangsmåten ifølge oppfinnelsen kan f. eks. bestå av et kammer som er dannet av et metallrør hvis mantelflate er perforert med små huller og som er omgitt av en kappe som står i forbindelse med kilden som leverer undertrykket. Etter at den myknede plastslange er anbragt inne i røret, brettes dens av rørets ene ende utragende ende over en fra kappen utragende ende av røret, og holdes i denne stilling ved hjelp av et ringformet legeme. Plastslangen som rager ut av rørets andre ende, klemmes flat mot kanten av rørenden ved hjelp av et elastisk ettergivende legeme, f. eks. plast, som trykkes mot rørenden og lukker denne. Undertrykket i kappen vil gjennom hullene i rørveggen suge slangen inn til rørveggen og dermed kan legemet som skal belegges med plastslangen føres inn i denne. Efter opphevelse av undertrykket i kammeret, vil plastslangen legge seg som et tettslut-tende belegg omkring legemet. A device for carrying out the method according to the invention can e.g. consist of a chamber which is formed by a metal tube whose outer surface is perforated with small holes and which is surrounded by a jacket which is connected to the source which supplies the negative pressure. After the softened plastic hose has been placed inside the pipe, its end protruding from one end of the pipe is folded over an end of the pipe protruding from the jacket, and held in this position by means of an annular body. The plastic hose that protrudes from the other end of the pipe is clamped flat against the edge of the pipe end by means of an elastic yielding body, e.g. plastic, which is pressed against the end of the pipe and closes it. The negative pressure in the jacket will suck the hose into the pipe wall through the holes in the pipe wall and thus the body to be coated with the plastic hose can be fed into it. After lifting the negative pressure in the chamber, the plastic hose will form a tight-fitting covering around the body.
