Abstract
Improved apparatus for continuously treating moving textile material in staple length fiber form by impregnating the moving fibers with a dye or other chemical, compressing and conveying the impregnated fibers in a continuous compacted mass form through an elongate heating tube to fix or react the dye chemical on the fibers, and periodically discharging in compacted mass sections of the fibers onto a conveyor which transports the fibers while they are being washed. The improvement in such apparatus comprises a pair of agitating rollers and a pin conveyor section disposed in the path of movement of the compacted fiber mass sections to break the sections apart and generally uniformly distribute the fibers on the washing conveyor to facilitate removal of excess dye or chemical therefrom.
