Abstract: A system for the handling of cassettes which are nested in a predetermined pattern to individually remove, orient and deliver each cassette to a work station and then nest in another predetermined pattern the cassettes having passed through the work station. The disclosed system includes an input hopper mechanism including a magazine and a gate, a track system for conveying cassettes from the hopper, a system for removing cassettes to a work station and returning the cassettes to a track, and an output hopper mechanism including an output magazine and a gate means for controlling the input and orientation of cassettes into the output hopper.

Abstract: A mechanism for threading cassette leader onto an automatic cassette splicer and loader. The threader with the automatic splicer and loader requires no manual intervention once the cassette is placed thereon and the cycle is initiated. The threader includes a leader pickup mechanism for drawing a loop of leader from a cassette, a leader placement assembly which engages the loop and extends the leader over a vacuum track, and a tape guide assembly including an arm to pivotally move one side of the loop away from the vacuum track of the splicer and loader and a guide plate adjacent the vacuum track to prevent tape from catching on the vacuum track. These various devices are driven pneumatically by means of a cam and pneumatic switch assembly.
