Abstract
A high-speed printer in which the carriage carrying a print wheel is coupled to a servo controlled driving motor having intermittent motion. The motor drives a helically grooved pulley, which has attached to it left and right cable segments. The other ends of the cable segments are attached to the movable carriage. A cable preload spring and friction pulley snubber combination maintains cable tension relatively constant. The snubber provides a tight cable system during normal carriage acceleration and deceleration. The preload spring allows for tension correction when the cable suffers from long-term stretching due to constructional stretching, that is, the normal tendency of wound cables to stretch due to seating of individual wires in the strand.
