In this video, we delve into the intricacies of making fine guide point adjustments in web guiding systems, particularly during processes like lamination. Traditional methods use a micrometer screw for adjustments, but this video explains how to make precise, real-time guide point changes automatically. Learn how to adjust the guide point by increments of 0.1 millimeters, ensuring optimal alignment without stopping the web movement.

## Transcript

now there are situations where you are guiding the web you got it at the part but you want to make a fine adjustment and with the traditional sensors there might be something like a micrometer and an operator needs to reach in and try to adjust that screw on the micrometer to move it back and forth to do what is called as a fine day point adjustment so think of it like a lamination process you got the wind allign guiding but you want to change that gide point just a little bit you don't want to make too much of an adjustment and you want to do that while the wind is running and that is what we call as a fine G point adjustment how to do the fine gate point adjustment right now the gate Point offset isus 119 mm and if I want to change that just a little bit then I if I want to increase that I can press that increases that the web gate is not going to move until it goes away from B so just to illustrate the SP thing now it reach the limit for the dead man and it's continuing there that's our fing G point adjustment so this allows you to be able to Mike uh make very fine adjustments to the guide point again the plus arrow allows you to increase that g point and minus Arrow allows you you would decrease that g Point that's what is called a fine G point adjustment and this adjustment can be done only when we are in automatic mode and then each press of that will take1 mm I think that's what it looks like1 mimet to move the gate BL
