ABSTRACT:
A frictional tensioning device for use in dispensing a continuous spool of ribbon or tape material under a uniform tension, regardless of the changing diameter of the spool. The device comprises a mounting pin secured to a fixed structure or base plate, the pin extending upwardly through an intermediate resilient base member having a sheet member of very low friction defining a layer disposed on the outer surface of the resilient base member, on which is positioned a thin flexible plate interposed between the frictional sheet member and the spool of tape material, so as to allow the spool and the flexible plate to rotate together about the pin under a controlled compressionable force provided by a spring-biased hub member mounted to the pin and held in the central core of the spool by a nut and a spring, thus establishing a means to apply the required compression on a given type of tape or ribbon being dispensed therefrom.
