US 4,066,221 A · Method of and apparatus for the tape loading and use of a single turntable in the rendition of a taped program

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. 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.

Dependent claims

Method of tape loading and using a turntable in the rendition of a taped program comprising the steps of:

a. defining a peripheral flange and tape entrance therethrough around a rotating turntable:
b. winding tape on said rotating turntable through said tape entrance and against said peripheral flange, the winding being of equal length per revolution of said turntable, each said winding being displaced radially inwardly by each successive winding and following inwardly curving paths of progressively greater curvature as the number of said windings increase;
c. biasing radially said windings adjacent said flange at a plurality of spaced points therearound for inhibiting said windings from curving inwardly at said bias points and to maximize curving therebetween and equal distribution therearound;
d. connecting the inboard and outboard tape ends of the loaded tape to form a closed loop with an off-turntable bight adapted to engage in and with cooperating apparatus for rendition of taped program;
e. continuously rotating the loaded turntable and simutaneously energizing said cooperating apparatus to draw tape from the inner winding and load tape at the outer winding in equal amounts per revolution of said turntable in continuous renditions of the taped program and the elimination of friction and slippage between windings.

Apparatus for the tape loading and use of a single turntable in the rendition of a taped program comprising:

a. means for peripherally flanging said turntable and rotating it on a hollow stationary shaft;
b. means for winding equal lengths of tape of a taped program on said flanged turntable at the periphery per revolution thereof for progressively displacing preceeding windings inwardly by succeeding windings;
c. means for leading a wound end of said tape off said turntable through associated rendition apparatus for the rendition of the taped program thereof;
and
d. means for connecting ends of said tape for peripheral re-winding on said turntable as said tape is wound off for the continuous rendition of the taped program.
