Abstract
Tows of fibers are wrapped around a mandrel or a central fiber core to form a cylindrical filter. At least one belt is located in position to make essentially linear contact with the cylindrical filter, and the at least one belt is driven so as to draw the tows of fiber onto and wrap the mandrel or the central fiber core and so as to move the cylindrical filter axially relative to the mandrel or with the central fiber core.
