Abstract

1371740 Coated optical fibre STANDARD TELEPHONES & CABLES Ltd 29 March 1973 15097/73 Headings B5A and B5B An optical communications fibre comprising a glass optical fibre 1 and an axially orientated plastics coating formed by feeding the optical fibre 1 into a plastics tube 5 extruded from a cross-head extruder 4 and drawing down the tube 5 on to the optical fibre 1. The latter may be fed into the cross-head 3 directly from a glass drawing apparatus or from a storage reel 2. The optical fibre 1 may be cooled to ambient temperature before entering the crosshead 3. The plastics tube 5 containing, but not in contact with, the fibre 1 may be passed through a cooling trough 6, a primary capstan 7 to a drawing and sizing die 8, a capstan 9 and a storage reel 10. The drawing down may be assisted by heat. The sizing die 8 may be dispensed with. The plastics material may be polyethylene terephthalate.

Description

(5) СПОСОБ ЗАЩИТЫ ГИБКОГО ЖГУТА (5) METHOD FOR PROTECTING A FLEXIBLE HARNESS

Изобретение относитс  к способам покрыти  оптических стекл нных волокон , используемых- в оптических передающих системах,.The invention relates to methods for coating optical glass fibers used in optical transmission systems.

Известен способ защиты гибкого жгута путем нанесени  оболочки методом экструзии в шприц-прессе С1 There is a known method of protecting a flexible rope by applying a shell by extrusion in a C1 syringe press.

Известный способ не позвол ет изготавливать световоды с высокой механической прочностью.The known method does not allow the manufacture of optical fibers with high mechanical strength.

Цель изобретени  - обеспечение защиты световода.The purpose of the invention is to protect the fiber.

Указанна  цель достигаетс  тем, . что нанесение на жгут оболочки методом экструзии осуществл ют из терефг талата полиэтилена с зазором относительно жгута, после чего охлаждают и обжимают оболочку до плотного прилегани  к жгуту.This goal is achieved by that the extrusion is applied to the tow band by means of polyethylene terefg with a gap relative to the tow, after which it is cooled and the sheath is pressed to fit tightly to the tow.

На чертеже показано устройство дл  нанесени  защитного покрыти  на жгут из стекл нного волокна.The drawing shows a device for applying a protective coating on a glass fiber tow.

Стекл нное волокно 1 с бобины 2 подаетс  через головку 3 экструдера 4 СТЕКЛОВОЛОКНАGlass fiber 1 from bobbin 2 is fed through the head 3 of the extruder 4 GLASS FIBER

с покрытием из терефталата полиэтийена . Оболочку 5 на жгут нанос т с зазором , после чего осуществл ют охлаждение ее в ванне 6 и обжатие до плотного прилегани  оболочки к жгуту прот гиванием через дюзу 7- При прот гивании материал оболочки раст гивает с  в аксиальном направлении и ориентируют молекулы пластмассы вдоль волокна, что повышает прочность покрыти .coated with polyethylene terephthalate. The shell 5 is applied with a gap on the rope, after which it is cooled in bath 6 and crimped until the shell fits snugly to the rope by pulling through nozzle 7. which increases the strength of the coating.

-Прот гивание жгута в оболочке приводитс  валиками 8 и 9. а наматываетIS с  он на бобину 10.- The wrapping of the tow in the sheath is driven by rollers 8 and 9. And it winds on the bobbin 10.
