摘要

The lower end of a tubular bundle 14 min of fibres is impregnated with a potting compound by a centrifugal technique in which the bundle 14 has its bottom end supported in a mould 12 which is rotated by a motor 22 through a belt drive 26, 28, 16. While the mould 12 and the bundle 14 are being rotated, potting compound is supplied from a reservoir 36 through a hose 38 and a duct 40 to the bottom of the bore of the bundle 14 within the mould 12. Centrifugal force causes the potting compound to flow outwards through the bundle until it fills the mould 12. The centrifugal force displaces air bubbles held between the fibres and ensures complete encapsulation of the fibres. When the mould 12 is full, spinning and the supply of potting compound is stopped and the end of the bundle 14 is left in the mould 12 until the potting compound has reached a desired state of cure.
