Abstract

The generation of tape tension, based on the capacity for elastic flow of elastomeric incompressible layers, in a tape transport apparatus employing at least one capstan in contact with supply and take-up reels of tape is accomplished by producing a higher compressive force at the point of contact between the take-up reel and the resiliently deformable peripheral portion of the capstan than at the point of contact between the supply reel and the capstan. The difference in compressive forces is brought about by an additional force which is produced by means of a drivable rotating body and is transmitted to the tape reel carriers by means of a cable which is guided over this rotating body.
