Abstract
A fiber treatment oven is disclosed in which hot gas is flowed parallel to and between fiber pathways within the oven to reduce deflection and breakage of fibers and to reduce end-to-end temperature variations in the oven. Hot gas is emitted centrally of the oven and flows toward ends of the oven. Preferably, an additional, generally tubular stream of hot gas is emitted centrally of the oven and generally surrounds and envelopes the fiber pathways to reduce side-to-side temperature variations.
