Det særegne ved denne anordning be-står i at det rundt hver muffe over den The peculiarity of this device is that around each sleeve above it
ytre tekstilkappe er lagt et visst antall a certain number of outer textile sheaths are laid
tråder som har meget mindre friksjonskoeffisient enn tekstilmaterialet threads that have a much lower coefficient of friction than the textile material
Oppfinnelsen skal beskrives nærmere The invention shall be described in more detail
under henvisning, som eksempel, til en te-lekommunikasjons-sjøkabel som er forsynt referring, as an example, to a telecommunications submarine cable provided
med forsterkere innesluttet i myke muffer. with amplifiers enclosed in soft sleeves.
Oppfinnelsen lar seg imidlertid også like However, the invention can also be liked

Diameteren for de muffer som inne-holdes i kablene har hittil vært begrenset The diameter of the sleeves contained in the cables has so far been limited

var det således nødvendig å legge kablen it was thus necessary to lay the cable

re strekk som utøves på kabelkjernen når den går ned i sjøen. Når det dreier seg om forsterkere med stor diameter kan klebingen mot tromlen, når kablen ligger i flere vindinger om denne, bli slik at den kraft som er nødvendig for å trekke av muffen og føre den ned i sjøen går opp i flere tonn, slik at de suksessive vindinger på muffen står i fare for å bli deformert på tromlen idet de opptar kraften fra fø-ringskniven i utleggingsmaskinen. re tension exerted on the cable core when it goes down into the sea. When it comes to amplifiers with a large diameter, the adhesion to the drum, when the cable is wound around it in several turns, can be such that the force required to pull off the sleeve and lead it into the sea amounts to several tonnes, so that the successive turns of the sleeve are in danger of being deformed on the drum as they absorb the force of the guide knife in the laying machine.
Selv om det ville være ønskelig ikke å overdrive den ytre diameter av muffen, spesielt når det gjelder arbeide på stort dyp, vil den begrensning av muffediame-teren som følger herav være temmelig sjenerende på grunn av sammentrengtheten av det utstyr som det er nødvendig å an-bringe i muffen eller på grunn av den betydning det i visse tilfeller kan ha å kon-sentrere utstyret på en kort lengde for å unngå sjenerende innbyrdes påvirkning. Dette er f. eks. tilfellet ved toveis sjøkabel-forsterkere for bærefrekvenser hvor det kan være av betydning å kunne ha en ytre diameter på ca. 200 mm. Although it would be desirable not to exaggerate the outer diameter of the sleeve, especially when working at great depth, the resulting limitation of the sleeve diameter would be rather troublesome due to the narrowness of the equipment that it is necessary to -bring in the sleeve or because of the importance it may have in certain cases to concentrate the equipment on a short length to avoid embarrassing mutual influence. This is e.g. the case with two-way submarine cable amplifiers for carrier frequencies where it can be important to be able to have an outer diameter of approx. 200 mm.
For å løse denne oppgave har det gan-ske visst vært foreslått å benytte en ma-skin med to tromler, men foruten at det da er nødvendig helt å endre de nåværende maskiner, bevirker forskjellene mellom kablens og muffens diameter variasjoner i avrullingshastigheten. Disse variasjoner kan selv ikke oppdelingen på to . tromler i elementer med uavhengige hjul lagt ved siden av hverandre på samme aksel ta hensyn til på en tilfredsstillende måte. To solve this task, it has certainly been proposed to use a machine with two drums, but apart from the fact that it is then necessary to completely change the current machines, the differences between the diameter of the cable and the sleeve cause variations in the unwinding speed. These variations cannot even be divided into two. drums in elements with independent wheels laid next to each other on the same axle take into account satisfactorily.
Anordningen i henhold til oppfinnelsen gjør det mulig, takket være anordningen av glide-tråder rundt muffene, å overvinne disse vanskeligheter, og å føre muffer med stor diameter over utleggingsmaskinen, hvor de er viklet opp i flere vindinger uten at det er nødvendig å endre den vanlige trommel for utleggingsmaskinene i kabel-skip. The device according to the invention makes it possible, thanks to the arrangement of sliding wires around the sleeves, to overcome these difficulties, and to pass sleeves of large diameter over the laying machine, where they are wound up in several turns without it being necessary to change it ordinary drum for the laying machines in cable ships.
Glidetrådene nedsetter friksjonen av kabelen ved muffene både ved berøring med føringskniven og ved berøringen med utleggingstromlen. Ved at retningene for disse friksjonskrefter er loddrette på hverandre, har det vist seg å være å foretrekke at vinkelen for glidetrådene med apparat-aksen er ca. 45°. Det har også vist seg at diameteren av glidetrådene fortrinnsvis bør være lik eller større enn 3 mm. Det er imidlertid klart at hverken den slagnings-vinklen eller den tråddiameter som er angitt er absolutt, og enhver annen vinkel eller diameter kan velges hvis det måtte passe. The sliding wires reduce the friction of the cable at the sleeves both when it comes into contact with the guide knife and when it comes into contact with the laying drum. As the directions of these frictional forces are perpendicular to each other, it has been shown to be preferable that the angle of the sliding wires with the device axis is approx. 45°. It has also been shown that the diameter of the sliding wires should preferably be equal to or greater than 3 mm. It is clear, however, that neither the pitch angle nor the wire diameter indicated is absolute, and any other angle or diameter may be chosen if appropriate.
På tegningen er det som eksempel vist mulige utførelsesformer for innretningen i henhold til oppfinnelsen. Fig. 1 viser et lengderiss av en muffe utført i henhold til oppfinnelsen. Fig. 2 og 3 viser snitt etter linjen A—B i fig. 1. The drawing shows, as an example, possible embodiments of the device according to the invention. Fig. 1 shows a longitudinal view of a sleeve made according to the invention. Fig. 2 and 3 show sections along the line A—B in fig. 1.
På tegningen betegner 1 en kabel med armering og ytre tekstilkappe, 2 betegner en del av kabelen som omfatter en muffe, og 3 betegner glidetråder som omslutter denne del og er pålagt under en vinkel a med muffeaksen. In the drawing, 1 denotes a cable with reinforcement and outer textile sheath, 2 denotes a part of the cable which comprises a sleeve, and 3 denotes sliding wires which enclose this part and are applied at an angle a with the sleeve axis.
Trådene 3 har i fig. 2 sirkelformet tverrsnitt, men av forskjellige grunner, spesielt av hensyn til klebingen mot over-flaten av muffen og også for å nedsette den samlede ytre diameter av denne, kan det være av betydning å gi trådene 3 halv-sirkelformet tverrsnitt, slik som vist i fig. 3. Det er imidlertid også mulig å bruke et vilkårlig annet tverrsnitt for glidetrådene. The threads 3 have in fig. 2 circular cross-section, but for various reasons, in particular with regard to the adhesion to the surface of the sleeve and also to reduce the overall outer diameter thereof, it may be important to give the threads 3 a semi-circular cross-section, as shown in fig. 3. However, it is also possible to use any other cross-section for the sliding wires.
Trådene som er slått skrueformet kan erstattes med en fletning eller av tråder som danner en rekke konsentriske ringer. The threads that are twisted helically can be replaced by a braid or by threads that form a series of concentric rings.
Glidetrådene kan være av stål, eller bronse eller vilkårlig annet metall. De kan også være av et ikke-metallisk material, f. eks. polystyrol, nylon osv. forutsatt at dets friksjonskoeffisient mot metallet i tromlen er liten. The sliding wires can be made of steel, or bronze or any other metal. They can also be of a non-metallic material, e.g. polystyrene, nylon, etc. provided that its coefficient of friction against the metal in the drum is small.
