The system is an improvement in an apparatus for transferring cable between a driven rotatable spool and a fixed spool where the rotatable spool is mounted on a stub shaft and the fixed spool is coaxially mounted with respect to the rotatable spool along a common axis. The improved combination comprises an arm which is secured to an axle which, in turn, in the absence of other constraints, would be freely rotatably mounted on the stub shaft. The arm extends in a direction substantially perpendicular to the common axis. A planetary pulley is mounted for rotation at the outer end of the arm, the radial plane of the planetary pulley being substantially parallel to the common axis, the planetary pulley being mounted so as to accommodate cable as it is being transferred between the rotatable spool and the fixed spool. Positive driving structure for the arm is provided which include an element which is secured to one face of the axle, and is adapted to be in driving contact with an actuatable, cooperative member which is operatively associated with the driven rotatable spool. Finally, positive braking structure for the arm are provided which includes an element which is secured to the other face of the axle, and which is adapted to be in driving contact with an actuatable cooperative member which is operatively associated with said fixed spool.
