Abstract
A concentric tape applicator has a support shaft that defines an axis and includes a structure for supporting a tape pad for rotation with the support shaft about the axis. Guide rollers are mounted on the support shaft for rotation concentrically about the axis for guiding tape from the tape pad for application to an elongated member advancing along the axis relative to the support shaft. A drive is directly coupled to the guide elements. A differential clutch is provided that has an input shaft directly coupled to the drive and an output shaft coupled to the support shaft for applying braking forces to the pad. A feedback circuit is provided for sensing the speed of rotation of the pad and applying a feedback signal to the clutch for regulating the excitation of the clutch to maintain a substantial uniform tension on the tape dispensed from the pad so potentially independently of the amount of tape remaining on the pad.
