Abstract
Abstract A magic sound track is transferred onto movie film by a machine which simultaneously feeds film and magnetic tape to a laminating zone where the film passes over a laminating wheel, an open channel curved capillary tube applies a bonding agent to an elongated area, and the magnetic sound track is laminated to the film. The machine is provided with fail-safe mechanisms to shut down the process in case of a break in the film or tape, or the absence of the bonding agent.
