 For the production of technical supplies needed both by studios and film distributors, "Intreprinderea de Stat Tehnocin" (The Tehnocin State Enterprise) was founded in 1950 and in 1959 merged with "Industria Optică Română" (The Romanian Optics Industry).Movie projectors for 35 mm and 16 mm film were produced, as were sound systems for movie theatres, reflecting lenses, dollies, and artificial studio lights.Likewise, so that there would be technical cadres well-prepared to work in studios and in the operation of movie projectors, professional schools for projectionists were founded at Craiova and Târgu-Mureș, while at Bucharest, a "technical school for technical personnel" was opened, intended to prepare movie theatre operators and studio managers.
