A dual path planetary transmission includes two planetary gearsets each having a sun gear member, a ring gear member, and a planet carrier assembly member. The pore distribution is monomodal and the porosity of the material is greater than 80%, conferring aerogel properties thereon while the absence of micropores confers a high thermal stability to these materials. This set of equipment for making flocked sole is highly automatic, easy to operate, save the labour and reduce the production cost. A carriage is movable along the longitudinal axis and includes a transverse axis.
