ABSTRACT:
A method and apparatus for loading a lengthy tape on a pair of turntables from a plurality of reels. The two turntables are appropriately supported adjacent to each other. The bottom of each turntable supports a large cam having a plurality of indentations defining a multi-lobed path over which a cam follower moves when the turntable is rotated. The cam follower is mounted on one arm of a bell crank of which the other arm supports a pusher member which applies an undulating force to the tape as it is being wound on the turntable. A sensing device is rotatably mounted in the center of each turntable and defines a take-off area for the tape being unwound from the center of the tape supported on the turntable. The sensing device controls a servo-motor which can rotate a half a turn in either direction to control an arm of a second bell crank which has the other arm supporting the first bell crank to shift the position of the first bell crank to thereby adjust the position of the pusher member with respect to the turntable. The surface of each turntable is provided with a plurality of radially extending friction strips and with film stripper rails which radiate outwardly and angularly. A synchronizer device equalizes the rate of the tape unwinding on one of the reels and the rate of the tape being unwound on the other reel. A shut-down control shuts down the operation of the apparatus whenever a break occurs in the tape along the path of its movement in either turntable area.
