Embodiment Construction

[0101] Referring now to the drawings in detail, and in particular first to figure 1 , which shows a device 1 according to the invention with a fiber furnace 2 and a drawing and sizing device 3 . It is assumed that downstream of the drawing and sizing device 3 is an assembly device 4 which assembles or conditions the drawn glass fibers or optical fibers 5 into fiber bundles 6 on a take-up reel 7 without, for example, the drawing and sizing device 3 on any reaction or feedback.

[0102] Assuming that between the fiber furnace 2 and the drawing and sizing equipment 3 is a cooling zone 8 , the glass fibers 5 pass through a funnel 9 . The cooling zone 8 has a flow collar 10 which is arranged directly downstream of the fiber furnace 2 and which serves the purpose of cooling the glass fibers 5 with a predetermined temperature profile.

[0103] Optical fibers or glass fibers 5 are drawn from a preform 11 which is introduced into the fiber furnace 2 by using a follower 12 . To this ...

Abstract

The device and the method of producing the glass fibers from a plurality of the preforms use a fiber furnace having heating bushes and a follow-up device for holding and feeding the preforms. The glass fibers are passed on to a drawing and sizing installation and wound as fiber bundles on take-up spools. A plurality of the heating bushes are disposed in a matrix like configuration to receiving a number of the preforms. The glass fibers are provided as a band such that the glass fibers are disposed next to one another when they are received by the drawing and sizing installation. A plurality of principal matrix axes have a given bias includ angle in relation one another, such that the matrix-like configuration is preferably a rhomboid-shaped configuration. A flow device creates a predetermined air flow in the heating bushes. A temperature and cooling control creates predetermined temperature profiles in the heating bushes.

Description

technical field [0001] The invention relates to a device for producing glass fibers, in particular multi-component glass fibers, from preforms, said device having a fiber furnace with a heating liner, with a follower for holding and feeding the preform into the heating liner equipment, and drawing and sizing equipment used to transfer glass fibers to assembly equipment. The present invention further relates to a method of manufacturing glass fibers from preforms, wherein the preforms are introduced into the heating liner of the fiber furnace by a follower, and the glass fibers drawn from the heating liner are cooled in the downstream cooling zone and passed through The drawing unit is passed to the assembly facility. Background technique [0002] In conventional apparatus and methods for making fiberglass, a preform is introduced into a heating bush and melted. Glass flows continuously from the preform and is pulled from the heating bushing below the fiber furnace. [000...
