| 1. An apparatus for preparation of an aqueous emulsion from a curable silicone composition, said apparatus comprising:
a continuous mixer for mixing (A) an organopolysiloxane having at least two silicon-bonded hydroxyl groups in one molecule,
(B) an organohydrogensiloxane having at least two silicon-bonded hydrogen atoms in one molecule, and (C) a curing catalyst;
a distribution device, which is connected to said continuous mixer from below; and comprises an outlet die having orifices
for discharging the liquid mixture of components (A), (B) and (C) from said continuous mixer in the form of threads or tapes
flowing down through said orifices, and a slit for discharging (D) an aqueous solution of a surface-active agent; and
an emulsifier connected from below to said outlet die of said distribution device.
