DEVICE AND PROCESS FOR EXPANDING STRAND MATERIAL

摘要

An expanding device is provided for expanding strand material into a wool-ty pe product. At least a portion of an internal nozzle section is adapted to be received in an outer nozzle section. A main body portion and a needle portion include a first inn er passage through which strand material passes to be expanded into a wool-type product . The main body portion has at least two bores extending through the main body portion which receive gas supplied by a gas stream source. The at least two bores communicate with the inner chamber and define a path for gas to travel to the inner chamber. The gas passes into the inner chamber and causes the strand material to move through the first passage.
