A tape transport wherein supply and takeup rolls are engaged by a resilient drive body disposed between the rolls, and urged against the rolls by means independent of the tape. Unidirectional brake means restrain rotation of the supply roll so as to tension a span of tape disposed between the rolls during feeding thereof. In one embodiment, a motor drives the rotating body directly. The brakes, applied at the hub of the supply roll, are individual to that particular supply roll to be carried therewith for use on all machines. In another embodiment, the drive body serves as a transfer roller to transfer forces between the rolls whereby one of two motors respectively connected to supply and takeup rolls drives the takeup roll while the other motor applies a drag to the rotation of the supply roll. In reverse feeding of tape, the functions of the two motors are reversed.
