Opfindelsen angår en fremgangsmåde til fremstilling af oppustelige legemer, såsom gummibåde, redningsflåder og lignende hullegemer bestående af vævet materiale, som er belagt med gummi eller gummiagtigt formstof, og ved hvilken fremgangsmåde til skårne dele af 5 det belagte vævede materiale ved klæbning eller svejsning forbindes med hinanden ved kantdele, som overlapper hinanden, og eventuelle udstyrsdele ved klæbning eller svejsning ved forbindelsessteder forbindes med det belagte vævede materiale, og belægningen på i det mindste den ene af kantdele, der skal forbindes med hinanden samt på 10 forbindelsesstederne for udstyrsdelene, inden forbindelsen foreta ges, gives en for forbindelsen fordelagtig overfladeruhed.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method of making inflatable bodies, such as inflatables, life rafts and similar hollow bodies made of woven material coated with rubber or rubbery resin, and to which the method of cutting portions of the coated woven material is joined by adhesive or welding. each other at overlapping edge portions, and any equipment parts by bonding or welding at connection points are joined to the coated woven material, and the coating on at least one of the edge portions to be connected to each other as well as at the connection points of the equipment parts prior to connection. is given a surface roughness advantageous to the compound.
Gummibåde og lignende oppustelige hullegemer opbygges sædvanligvis af færdigbelagte formdele, der er tilskåret efter skabeloner, og ved hjælp af klæbe- eller svejseforbindelser forbin-15 des med hinanden ved kantsømme, der sædvanligvis overlapper hinanden. Også de nødvendige og ekstra udstyrsdele, såsom skurelister, besætninger for gribeliner, bærehåndtag og fastgørelses- eller slæbeøjer, åretolle, sædeholdere, oppustnings- og lenseventiler, mellemvægge mellem flydel egernerne og lignende anbringes ved hjælp af 20 klæbe-eller svejseforbindelser. Forberedelsen og fremstillingen af forbindelsen mellem materialet og af de forskellige dele optager en forholdsvis stor del af hele fremstillingstiden, således at det i praksis længe har været et ønske at kunne formindske arbejds- og navnlig tidsforbruget hertil ved hjælp af forenklede fremgangsmåder.Inflatables and similar inflatable hollow bodies are usually made up of pre-molded molded parts that are cut according to templates, and are bonded to each other by edge or weld joints, which usually overlap. Also necessary and additional equipment parts, such as scouring moldings, gripper lines, carrying handles and fastening or towing eyes, year rollers, seat holders, inflation and bilge valves, partitions between the float squirrels and the like are applied by means of 20 adhesive or welding connections. The preparation and preparation of the connection between the material and the various parts occupies a relatively large part of the entire production time, so that in practice it has long been a desire to be able to reduce the labor and especially the time spent therefor by simplified methods.
25 Da der imidlertid stilles særlige krav netop med hensyn til holdbarheden og pålideligheden af forbindelserne, har disse hidtil stået i vejen for alle rationaliseringsbestræbelser. Således er det af arbejdstekniske grunde nødvendigt først at foretage en opruning af klæbe- eller svejsefladerne, hvilket med den nødvendige omhyggelig-30 hed kun kan foretages manuelt, f.eks. ved hjælp af motordrevne slibeskiver, der drives over bøjelige aksler. At der herunder af sikkerhedsgrunde skal bearbejdes væsentligt større overfladeafsnit end de egentlige klæbeflader er endvidere en ulempe.25 However, since special requirements are made precisely with regard to the durability and reliability of the compounds, so far they have stood in the way of all rationalization efforts. Thus, for technical reasons, it is necessary to first clean the adhesive or welding surfaces, which with the necessary care can only be done manually, e.g. by means of motor-driven grinding wheels driven over flexible shafts. Furthermore, the fact that substantially larger surface sections than the actual adhesive surfaces must be machined for safety reasons is a disadvantage.
Formålet med opfindelsen er at forenkle fremstillingen af 35 klæbeforbindelserne mellem op mod hinanden stødende afsnit tilskårne dele af vand-og lufttæt belagt materiale, uden at deres brudstyrke og holdbarhed forringes, og herunder som en følge deraf at opnå en betydelig reduktion af det til opbygning af oppustelige hullegemer af alle arter nødvendige arbejds- og tidsforbrug under opnåelse af i 2The object of the invention is to simplify the manufacture of the adhesive joints between abutting sections of cut water and airtight coated material without impairing their tensile strength and durability, and consequently to achieve a considerable reduction in the construction of the adhesive. inflatable caverns of all kinds necessary labor and time consumed while obtaining in 2

det mindste samme kvalitet af det færdige produkt.at least the same quality of the finished product.
Denne opgave løses ifølge opfindelsen ved, at et belagt vævet materiale, der over hele dets flade er udformet med overfla-deruheden i belægningen, anvendes uden yderligere opruning.This task is solved according to the invention in that a coated woven material, which is formed over its entire surface with the surface roughness of the coating, is used without further rooting.
5 Ved indførelsen af sådanne i sig selv færdigfremstillede baner af vævet amteriale som nye konstruktionselementer til fremstillingen af oppustelige hul- og flydelegemer, opnås ved hjælp af opfindelsen overraskende fordele, der hverken, hvad angår resultatet eller omfanget kunne forudses. Den allerede ved selve fremstillingen 10 over den fulde flade af belægningen udformede ensartede overfladestrukturering erstatter den ellers nødvendige lokale opruning af klæbestederne. Ved bortfaldet af de til fremstillingen af klæbestederne nødvendige arbejdsprocesser elimineres også den stadige fare for ubemærkede ødelæggelser af det vævede materiale med de deraf 15 forårsagede følgeskader under artiklens senere anvendelse. Da også de med enhver mekanisk bearbejdning uundgåeligee uregelmæssigheder i området ved klæbestederne og navnlig de ved afslibningen af det yderste lagmateriale forårsagede fordybninger i forhold til de omgivende overfladeområder er elimineret, opnås gunstigere betin-20 gelser til opnåelse af betydeligt forbedrede klæbeværdier. Dette gælder i særlig grad de kritiske overgangsområder ved kanterne af de med hinanden forbundne dele.In introducing such self-made webs of woven amterial as new structural elements for the manufacture of inflatable hollow and floating bodies, the invention achieves surprising advantages that neither the result nor the scope could be foreseen. The uniform surface texturing already formed over the full surface 10 of the coating itself replaces the otherwise necessary local rooting of the adhesive. In the absence of the working processes necessary for the fabrication of the adhesive, the constant danger of unnoticed destruction of the woven material with the consequent consequential damage during the subsequent use of the article is also eliminated. Since also the inevitable irregularities in the area of the adhesive with any mechanical machining and in particular the depressions caused by the grinding of the outer layer material with respect to the surrounding surface areas, more favorable conditions are obtained to obtain considerably improved adhesive values. This is especially true of the critical transition areas at the edges of the interconnected parts.
Foruden det reducerede arbejds- og tidsforbrug og den forbedrede holdbarhed af klæbeforbindelserne opnås ved hjælp af 25 opfindelsen som en indirekte følgevirkning også fremstil!ingstek- niske fordele: Da der ikke skal afslibes materiale, kan banerne af vævet materiale forsynes med en belægning med mindre tykkelse, således at både materialeomkostningerne og vægten af den færdige artikel kan reduceres uden forringelse af kvaliteten. Yderligere 30 omkostningsreduktioner opnås som følge af muligheden for med mindst mulige udskæringsspild at kunne udskære de nødvendige formdele af en og samme bane uden hensyn til deres tekniske funktion. Endelig er de færdige artikler fordelagtigere i brug på grund af den i alle områder ensartede overfladeruhed, der f.eks. i tilfælde af gummibåde 35 og andre flydelegemer gør ombordstigning fra vandet væsentligt lettere.In addition to the reduced working and time consumption and the improved durability of the adhesive compounds, the invention provides as an indirect consequence also manufacturing advantages: Since no material has to be sanded, the webs of woven material can be provided with a less thickness coating. so that both the material cost and the weight of the finished article can be reduced without deteriorating quality. Another 30 cost reductions are achieved due to the possibility of cutting the required mold parts of one and the same web with the least possible cutting waste, regardless of their technical function. Finally, the finished articles are more advantageous in use because of the uniform surface roughness in all areas, which e.g. in the case of inflatables 35 and other floating bodies, boarding from the water significantly facilitates.
Til fremstilling af det vævede belagte materiale kan anvendes i og for sig kendte, fortrinsvis kontinuerlige fremgangsmåder, hvor det elastomere belægningsmateriale under tryk- og varmepåvirk- 3For the preparation of the woven coated material can be used per se known, preferably continuous methods, in which the elastomeric coating material under pressure and heat is applied.

Der kan da samtidig med trykpåvirkningen indformes de fordybninger i belægningen, der danner overfladeruheden, og hertil kan anvendes graverede eller med 5 formekapper forsynede valser eller synkront medløbende pålagte væveller foliebaner.bonding with permanent bond to the tissue e.g. is vulcanized or crosslinked between the heated rollers of a calender. At the same time, the depressions in the coating forming the surface roughness can be formed at the same time as engraved or rollers or synchronously applied woven sheets or foil webs can be used for this.
