ABSTRACT:
A synthetic granulate is fed into an extruder through an inclined upper part transiting into a short vertical lower part communicating with an inlet in the extruder. A down shaft of smaller diameter for feeding a stream of a dye stuff projects through the inclined part and terminates about midway in the vertical lower part. The stream of synthetic granulate forms below the outlet of the filling channel a funnel-shaped cavity onto which a stream of dosed dye stuff continuously falls. The interface of the cavity with the synthetic granules is continuously renewed and thus a uniform stream of the dye stuff is admixed to the granules.
