Abstract
A drive control system for a binding line having first and second separate binding-line segments, includes a first motor for driving the first binding-line segment, a second motor independent of the first motor for driving the second binding-line segment, and a controller coupled to the first and second motors. The controller is operable in an independent or asynchronous mode for controlling the first and second motors so that the first and second binding-line segments operate independently, and is also operable in a synchronous mode for controlling the first and second motors so that the first and second binding-line segments operate in synchronism with one another.
