Abstract

L'invention concerne une machine de montage cinématographique. Selon l'invention elle comprend un arbre mené rotatif 60, un tambour de film 16 coaxial autour de l'arbre, un prisme cylindrique 80 également coaxial sur l'arbre, le prisme ayant un noyau creux et plusieurs facettes sur sa surface interne, chaque facette étant disposée dans un plan perpendiculaire à un rayon provenant de l'axe du prisme, les rayons étant espacés de façon equidistante autour l'axe et se trouvant dans un plan commun, le tambour et le prisme sont axialement interconnectés sur l'arbre pour tourner ensemble; une source lumineuse; un moyen optique pour diriger le premier trajet lumineux vers un second trajet parallèle à l'arbre puis le rediriger vers un troisième trajet parallèle au premier traversant le prisme cylindrique à travers au moins une facette; une premiere lentille de correction, et un moyen pour supporter l'ensemble. L'invention s'applique notamment à l'industrie cinématographiqueThe invention relates to a cinematographic editing machine. According to the invention it comprises a rotary driven shaft 60, a film drum 16 coaxial around the shaft, a cylindrical prism 80 also coaxial on the shaft, the prism having a hollow core and several facets on its internal surface, each facet being disposed in a plane perpendicular to a ray from the axis of the prism, the rays being equidistantly spaced around the axis and lying in a common plane, the drum and the prism are axially interconnected on the shaft to turn together; a light source; optical means for directing the first light path to a second path parallel to the shaft and then redirecting it to a third path parallel to the first one passing through the cylindrical prism through at least one facet; a first correction lens, and a means to support the whole. The invention applies in particular to the film industry
