A drive system for use in rotating a drive shaft of a component of a binding line can be selectively coupled to a primary motive power source associated with the binding line or to a secondary motive power source operated out of synchronization with binding line. The drive system includes a first drive pulley connected to the primary motive power source, a second drive pulley connected to the secondary motive power source and a double-sided drive belt which engages the drive shaft. A pulley set is coupled to the double-sided drive belt and is rotatable about a pivot point between first and second positions to transfer the double-sided drive belt between the first and second drive pulleys.
