Abstract
An expanding device for expanding strand material into a wool-type product includes outer and internal nozzle sections. The outer nozzle section has an entrance portion, an intermediate portion and an exit portion. At least a portion of the internal nozzle section is adapted to be received in the outer nozzle section. It includes a main body portion and a needle portion extending from the main body portion. The main body and needle portions include a first inner passage through which strand material passes to be expanded into a wool-type product. The needle and main body portions define with inner surfaces of the entrance and intermediate portions of the outer nozzle section an inner chamber. 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. The gas also effects expansion of the strand material into a wool-type product.
