  • Method of and apparatus for the tape loading and use of a single turntable in the rendition of a taped program
    Patent number: 4448362
    Abstract: 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.
