Abstract
The transfer of a tape or ribbon wound up on a shaft, to a second parallel shaft, requires synchronised rotation. In order to keep the tape under tension, the shaft which receives the tape has to rotate fractionally faster than the shaft from which the tap eunwinds. This speed differential is achieved by having the friction belt driving the two shafts on different diameter sections. The two shaft diameters are linked by a taper so that the drive belt is free to move from the larger to the smaller diameter and vice versa. When the tape transfer is reversed, the drive belt motion is to be reversed. This causes the belt to drive the receiving shaft on the larger diameter and the dispensing shaft on the smaller diameter. In this way the correct speed differential is automatically maintained.
