Note: The filament may be fully closed in plan, or may embrace an arc of less than 360 degrees.

The English term "Cylindrical filament" is usually limited to the case of a closed cylinder.

Otherwise, the English term used is "Bunch filament" (2-3-220).




Please note that this is the term as it stands in the original IALA Dictionary edition (1970-1989)
