What are Pneumo-Hydraulic Web Guides?
Many displacement guides, steering guides, unwind / rewind guides manufactured in the 1960’s, 1970's, 1980’s and 1990's were controlled using both pneumatic and hydraulic control systems which are often referred to as pneumo-hydraulic web guides. These web guide were really common before the mass adoption of the electronic (analog and digital) controllers and electric actuators.
Roll-2-Roll Technologies shows just how easy it to set up its web guiding system. The automatic function does all the work, so you don't have to. Just press the automatic button and let it roll.

As a real plug-and-play system, ARIS adapts to any material, requires no calibration, and very little set-up time. First plug in the sensor to the 12 prong outlet in the back of the machine, using the guide notch that aligns the plug to the outlet. Once the sensor is plugged in, tighten the lock collar to hold the sensor cord in place. Slide the sensor into the sensor guide rail.
Make sure the middle of the sensor is aligned with the material’s edge. Once connected to a 24 volt power supply, the user operator interface featuring language independent icons will come. A green sensor indicator will verify an operable sensor. Above the icons you will see the material edge, position indicator, represented by a green and red bars.
When the material is in correct position, you will see one red bar and one green bar. If it's incorrectly placed, you will either see no green bar or red bars on both sides of the green. Once the sensor has been aligned with web, secure the sensor using the thumb screws. When the screen turns on, the automatic/manual icon will indicating the guides last operating condition.
A green icon indicates the guide is in automatic operation. A red icon indicates the guide is in manual operation. The operator can change the condition by pressing the icon once. ARIS does most of the work through its automatic option, so press the icon to set to green and let it roll.
We are often asked how to calibrate our sensors. This video will show that you don't need to calibrate our sensor.

Hi, this is Pedro Velasco with Roll-2-Roll Technologies We want to answer one of the questions that reader in e-news sent us. His question was literally just how do you calibrate your sensors and one of the things we do with Roll-2-Roll Technologies with what we have developed It's that you have to, you don't need to do any calibration of our sensors. Right here today I'm going to do a very short demo using one of our demo units plus two of our main sensors, the 48 millimeters White light sensor to use for contrast sensing and edge sensing and then our white 221 millimeter sensors infrared which we use for edge detection but also for measuring width and center guiding. So let us show you how.
In this case you notice immediately as soon as I plug it in the sensor came on with no need of any other procedure in just coming you know. Now as you can see right now on the screen the sensor I have to go and tell it find the sensor It's searching and then as soon as I put the material It detects where the sensor is at. As you can see it's actually detecting the material as it goes through Ok so now let's say that I want to change the sensor for some other reason and now all [I] do is just unplug the sensor And as soon as I unplug it the display tells us that there's no sensor there and at the same time I'm going to plug in one of our featured sensors the 221 millimeter sensor which has many capabilities like for example We can do edge detection, it can do width sensing and immediately it detects a sensor there. However I'm going to do a search sensor and the same procedure and as soon as I put material it detects the material.
Now it is only guiding off on the edge of the material on the leading edge. That is how simple it is Change Sensors and as you can see there's no need for calibration We hope that this video has helped you understand a little bit more about our about our technology And we will continue to show more stuff, but especially the features that are sensors have. Thank you.
Web width measurement is a common need in the converting industry. This video shows the web width measurement application with the WPS.

Hi, this is Pedro Velasco with Roll-2-Roll Technologies. Today we talk a little bit as things that we can do with our sensors. Now our web guides are capable of doing edge guiding or center guiding with just a touch of an icon and that is because of our sensor technology. Now our sensors on their own they can actually have many other features that deal with that application.
For example this 221 mm sensor, we can use it to monitor the width of any material that is within the 221 millimeter sensing window. In this case they can measure the width, it can also detect that there are differences in the width and therefore send out a signal to tell you that there's something wrong with it. Now we can also do that, let's say that the sensing the material is wider than the sensing window. Well we can also use two sensors we can use two 221 mm or 2 48 mm and then hook them up to our sensor control unit and keep on doing that same application which is measuring the web width or at the same time controlling or monitoring the web width in case you want to make sure that the material is within specs in width wise.
This can be done with any of our sensors. This can be done with our 221 millimeter sensor the WPS 221 IR or this can be done with our 48. There are 16 mm sensors too and also with our new sensor the 440. Now this is some of the features that we have and we will talk some more about other features in future videos Thank you very much
