<p>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 (91) through a tunnel (92) and into a two stage diverging nozzle (120) to slow down the fibers for an organized collection in the collection section (150). The invention further includes an inflatable bladder (185) in a discharge section (181) for initiating the formation of the log and a mesh screen (155) in the collection section (150) for reducing the occurrence of fiber blow out through the gas discharge ports (152).</p> |
