Hello,
Like everyone has said, the speed should be the same in each direction of travel for the traverse guide pulley. Most spooling technology or concepts are the same regardless of the wire size or type. The only difference is that with the size wire you are drawing and the typical speed that this size wire may be drawn, results in the spool rotating at very high rpm. In some cases the traverse length may be 3-6 inches and the barrel of the spool only about 2 inches in diameter. Obviously at 5,000 feet per minute, the spool rpm would be quite high ( up to about 10,000 to start) Also with a 3-4 inch traverse length the traverse motor would be reversing about 400 times a minute and half this if drawing speed is only 2,500 fpm. This means that the reversing operation has to be nearly instantaneous. Expensive stepper motors work well. The problem that generally occurs is that you cannot begin the reversing operation after the traverse has traveled approximately the width of the spool because it take the wire longer to reverse direction than it take the motor to reverse direction. So unless you have an optically controlled traverse your total traverse travel may be only 3.75 inches or less when the spool traverse length is 4 inches. This prevents excessive build up at the flanges. For a manual control you have to just experiment and keep you eye on it. The optically controlled traverses see the build up and compensate by automatically adjusting the traverse length until the excessive build up has leveled off.
