In 2020 we hosted a webinar on web guiding applications and advanced web guiding concepts as a continuation of the educational series web guiding fundamentals. This webinar was the follow up on our seminar on Web Guiding Fundamentals, presented earlier that year, and commented in a series of blog posts in 2021. We would like to share some comments on the points presented in this webinar in the form of a series of blogs.
The line has to be of the same width and color in order for the sensor to track it. Any variation and the sensor will not recognize it. The same thing happens when using the negative space as guiding feature.
The customer was in the process of building a new converting machine but wanted to source the web guiding systems from a new supplier. They were facing three main issues that led them to seek a new supplier: a need for integration, ease of use and lead time. After searching online and reviewing the current manufacturer of their web guide and other competitors, he came across our web site.
So far we have discussed the different types of web guiding systems for converting applications. You now should know the different types of web guiding systems, and their design and installation recommendations. Also, you should have an idea of why web guiding is needed and where they should be installed in converting operations. In this blog post we will address a component of a web guiding system, the web guide actuators.
End and center pivot guides do not displace the web, they only have the angle of rotation to reposition the web. This makes them very slow in term of response, and therefore, are not an ideal choice in web guiding options.
However, even though we mention four main components, the web has to be considered a component of the web guiding system.
In our previous post on web guiding fundamentals, we mentioned the terminal web guides. These are web guides that are found at the start or the end of the process. Their location is usually on an unwind or a rewind stand. As we discussed, their installation depends on whether the guiding system is used for unwinding a roll of web or rewind a processed web into a roll.
