In this video, we explore the two main reasons for using center guiding in web handling systems, focusing on the advantages it brings when dealing with varying web widths and poor edge quality. The SCU6x Controller's advanced sensor technology allows seamless adjustments without the need to move sensors, accommodating significant width changes efficiently. This ensures high response times and minimizes wear on actuators. Additionally, for materials with irregular edges, center guiding helps average the measurements from both sides, leading to smoother edge profiles and improved roll quality. Learn how the SCU6x Controller can enhance your web handling process.

there are two main reasons why somebody would use Center guiding one is if you're changing web widths and you want to align the material to the center of the machine then Center guiding is the best option where you would place two sensors on either side and this those Those sensors are equidistance from the center line of the machine so when the web width changes you don't ever have to move the sensors and it automatically adust adjust itself because it's going to look at the left portion of the web seen by the left sensor and the right portion seen by the right sensor this is one of the common features that we have or common value proposition from our products is that our sensors can go anywhere from 48 mm up to 960 mm that means you can have a WID change of about 996 mm up to about 1920 mm without needing to move move the sensor this provides a lot of range and flexibility to be able to have a system that can adapt to Wick changes on the flight the older generation systems might have some actuators that move the sensors based on the wick change and more often than not what happens is that those actuators have their own control Loop that needs to be tuned the actuators can wear these are the actuators for the sensors that could wear over time and that creates an issue and then the response time especially when you do a WID change on the fly with those kind of systems is going to be much lower than compared to a system with a sensor that is wide enough to cover all the WID changes so that's one of the main reasons for using Center guiding is that you can do different widths without moving the sensors whenever the WID changes the second main reason why you would use Center guiding is that let's say say you have an edge especially some kind of an extruded Edge and the edge quality might not be great so before it goes into a slitter you you have an edge and the edge is not that great instead of aligning to one edge of the web in that case if you use two sensors and then use the center line position it takes the average of the left Edge and the right Edge and does the measurement that is going to be the center line measurement and it's going to guide the web to the center this is one of the biggest Advantage for using two sensors in doing this inter guiding and especially when you have irregular edges those edges variations are not going to be identical on both sides this Smooths out your edge profile and allows you to guide the web in the middle of the machine and that significantly improves the wound roll quality especially if you don't have a pretty good slit Edge so the advantage is that you are averaging based on two Edge measurements and this helps in smoothing out the edge position those are the two main reasons why you would use Center guide
