摘要：
A device for texturizing strand material into a wool-type product includes outer and inner nozzle sections. The outer and inner nozzle sections interface and define a passage through which the strand material travels. At least a portion of the passage has a non-uniform diameter that increases in a direction moving away from an input end of the device.
