Arrangement for coating optical fibres
First Claim
1. An arrangement for coating a fiber comprising:
- (a) a housing provided with a sidewall portion, a bottom wall portion essentially transverse to said sidewall portion, and including a pressure chamber for providing liquid coating under pressure on a fiber passing through said pressure chamber;
(b) a closure member transverse to, and cooperating with, the sidewall portion of said housing for closing the upper side of said pressure chamber and comprising a guide duct with an inlet opening for the supply and guidance of a fiber to be coated by liquid coating in said pressure chamber;
(c) a supply opening situated in a wall of said housing for supplying said liquid coating to said pressure chamber;
(d) an overflow opening for said liquid coating material situated in the sidewall portion of said housing, and(e) a nozzle situated in the bottom wall portion of said housing and provided with an opening, coaxial with said guide duct and in communication with said pressure chamber,characterized in that said guide duct is provided in a tubular guide member secured in said closure member and having a free end adjustable in the radial direction.

Abstract
An arrangement for coating a fibre, more particularly an optical fibre, comprising a housing (31) with a pressure chamber (61) which is in communication with a connection (63) for the supply of liquid coating material. A fibre to be coated is supplied via a guide duct (59) in a tubular guide member (55), traverses the pressure chamber (61) and leaves the device (11) via an outlet opening (41) in a nozzle (40). The tubular guide member (55) is made of an elastically deformable material. By means of two spindles (79), the end of the tubular guide member (55) can be adjusted so that the coating is centered with respect to the fibre and a coaxial location of fibre and coating is obtained.
