The solutions they had found were very expensive and did not provide a solution to their problem. They had been manually guiding an expensive specialty material, with a high cost of downtime and wasted materials.. The material had to be guided based on a line that was within other lines. We were contacted by them and during the conversation we understood that there were three main issues: guide a web on a line within other lines, compact design of the web guide, and lead time. ## Our Solution We offered a compact web guide system with contrast sensing for line guiding, with integrated operator interface display and 10 inch rollers for plug and play installation and operation. After installing the first two units, the customer approached us again with an interesting request: they wanted to be able to use the web guide in both directions. Web guiding dynamics does not allow for a web guiding system to guide in both directions. We came up with a simple solution: Install the web guide on a plate that would rotate horizontally 180o to reverse the direction of guiding. This required the addition of a remote operator interface to allow access to the operator upon turning the web guide direction. ![Contrast Sensing Applications](https://r2r.tech/sites/default/files/inline-images/Untitled%20presentation%20%283%29_3.jpg) ## ## Results or Customer Satisfaction At the end, the customer was very happy with the technology and the support provided.
