A turntable is rotated to wind the tape of a taped program thereon in equal lengths per revolution thereof. Each equal winding forces the preceeding windings inwardly on the turntable to assume progressively curving paths as the respective windings recede from the periphery of the turntable. Pressure pads are equally spaced around the periphery of the turntable and rotate therewith. The pressure pads extend radially, and frictionally engage the top edges of the tape windings which follow increasingly curved paths therebetween as the equal windings are forced inwardly by succeeding equal windings. The ends of the tape are connected leaving a portion of the closed loop formed thereby for engagement by associated apparatus and rendition thereby of the taped program. Since all of the windings on the turntable are of the same length per rotation thereof, tape can be simultaneously wound on and off the turntable as it is rotated with no slippage and friction between windings, and as the beginning and end of the taped program are joined, the program can be repeated for as many performances as desired, with only monitoring for mechanical failures required. |
