PCT No. PCT/AU86/00263 Sec. 371 Date May 27, 1987 Sec. 102(e) Date May 27, 1987 PCT Filed Sep. 5, 1986 PCT Pub. No. WO87/01451 PCT Pub. Date Mar. 12, 1987.A flow cell for use in a fibre diameter measurement apparatus to obtain preferential alignment of the fibers in which fibers are caused to flow through a passage (14) the walls (16 and 16a) of which diverge in the direction of flow thereby causing forces to act on the fibres to rotate the ends of the fibres towards the diverging sides of the passage and thus rotate the fibers to a larger angle to the direction of flow.
