Abstract:
A device for pulling an elongate member includes a rotational motor having an output and a rotating drum connected to the output of said rotational motor. The device further includes a guide mechanism for guiding the resilient elongate element onto, around at least a portion of the circumference of, and off of, the rotating drum. When the rotational motor turns the rotating drum, the rotating drum thereby continuously pulls the resilient elongate element through the device.
