Abstract

1,176,800. Tape transport. W. HUNGERBUHLER, [trading as SONDOR WILLY HUNGERBUHLER]. 8 Dec., 1966 [10 Dec., 1965], No. 54932/66. Heading G5R. A transport system for perforated magnetic sound tape 5 which can be operated in synchronism with a cinematograph film comprises sprocket drive wheels 4 driven by a stepping motor, spring loaded filtering rollers 3 and guides 2 which convert the step motion into a smooth motion past the magnetic heads 1 and a source of energizing pulses for the stepping motor. The energizing pulses may be synchronizing pulses from a camera or film projector, may be derived from a pilot tone recorded on a tape to be copied or derived from a television synchronizing signal. In a second ambodiment the tape is driven by a drum having a non-slip surface.
