This is a Showmark UniSpooler, specially configured for wire cleaning process where we've got the pay loss section and the take up section built on two separate frames, and they could be separated as far as required by the process to feed the wire through a cleaning tank. Tt can also be an annealing furnace, or any other process where you need to put something in between the payoff and the take up. And these two sections can be separated as far as needed. This particular machine has a few interesting features on it. One of them is our tail stocks, which here I'll stop at momentarily.
Tail stocks are used whenever you have a spool that might be heavier than one can be supported by just a plain cantilever shaft. These are 15 millimeter shafts on this machine, which we normally spec for about a 15 pound load, maybe 20 pounds if it's a narrow spool that can be mounted close to the bearing. But with the tailstock, you can put about a 50 pound spool on there. So we've got that on both the tail off and that take up sides of the machine. We also have closed loop electronic brake on here, where we're monitoring the diameter change of the pay off spool with an ultrasonic sensor below it that constantly monitors the diameter change. And as that spool gets smaller, that will lower the amount of current going to the brake to reduce the amount of, of torque generated by the brake. With the goal of maintaining constant tension, it does a pretty good job of that.
Moving over, we've got five inch diameter guide wheels on here. And this assembly here is a combination length tracker, where we've got a high resolution encoder on the backside of it, measuring the material that's wound. And also built into is a an optical wire brake sensor. So if the material either runs out or breaks, the machine will sense that it automatically stopped. And we have a switch on the side of our control box to turn that function off or on sometimes at the beginning of a run, you want to turn it off until things get tightened up enough. Or even something once in a while you have a fiber or wire that's so fine, that the sensor might have trouble picking it up, in which case you might want to bypass its function to eliminate false stops. So the the wire path is around here. And right now we have bare fiber optic wire on here. So it's very fine. That might be hard to see. But it's running around that guide wheel under here and, you know, presumably through the cleaning tank in this section, round up over torture version unit, where we've got the ability to adjust for the spacing of the wire on the take up spool with with this dial here with this ratchet. And then here you adjust the turnaround points of the traverse to match the spool flanges. And again, just like on the other side, we have our tail stocks.
So the other unique function of this machine is that normally a standard Winder or unit spooler turns the take up motor at a constant RPM. So as that spool builds up, the linear rate of the wire running through it will increase proportionally. This machine uses a closed loop speed controller that's reading the speed directly off of our our high resolution length tracker, it's converting it into a speed and here we're able to set a desired linear speed that's right now set for 20 feet per minute. And if I turn it on it'll be a slight delay but it'll start running and that's the actual speed there right now. The other thing right now to is we have a length tracker on here as well. It was set to stop automatically at 10 feet which it reached. That's why it stopped and reset that and it will start up again momentarily. Here it goes and go down to a much slower crawl. In this machine, this customer wanted a very slow machine. So right now it's controlling at 15 feet per minute. You see it's a very smooth, gradual wind, I can increase scope the 40 feet per minute, you see it speed up and this one is set to a maximum of 50. It can be much faster if that's the requirement. But here we're, I think I said before it's set for 10 feet except for 100 feet. And when we reach 100 feet, you'll see it stop these two controls here or the indicator for the brake on the payoff and here I can raise or lower that that brake setting here about the head 100 feet and you'll see it stop. So that's it. Thank you very much.
