Apparatus for making and collecting continuous fibers in the form of a rod-shaped batt

摘要

This invention relates to making backwindable rod shaped batts or logs from highly oriented flash-spun continuous fibers. The fibers are conducted from the exit of a spinneret through a tunnel and into a two stage diverging nozzle to slow down the fibers for an organized collection in the collection section. The invention further includes an inflatable bladder in a discharge section for initiating the formation of the log and a mesh screen in the collection section for reducing the occurrence of fiber blow out through the gas discharge ports.
