Web Guiding Fundamentals - Normal Entry Rule

Most web guides work on the fundamental principle of Normal Entry.

This rule states that a web approaching a roller will align itself perpendicular to the axis of rotation of the roller. The Normal Entry principle accounts for one of the most common defects in a converting line, roller misalignment. If your converting line has one roller that is not correctly aligned perpendicularly to the required path of the web, the web will move in order to be perpendicular to the misaligned roller.

Web Guiding Fundamentals - Intermediate Web Guides

Intermediate Web Guides

Used before a critical process in the converting line 

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.

Plant Superintendent uses Web Guide Upgrade Kits on their Converting Lines

A nightmare to any Plant Superintendent or Manager, failing web guides that no longer have spare parts in the industry

Dallas Plastic was dealing with a difficult situation that was starting to affect their productivity.

Imagine having several converting lines with old web guide systems that were starting to fail. Worst of all, the suppliers consulted could not offer them replacement parts since this equipment was no longer manufactured. It seemed like the only option was to buy complete new units.

Web Guiding Fundamentals - Terminal Web Guides

The web at the start and end of your converting line needs to be properly aligned to have a good conversion process and a well wound roll for your customers

It's an advantage to know what you are dealing with when aligning your web as it enters your converting process or is being wound into a processed roll. Here's some information that should be of help to you.

The uncertainty of trade shows in 2021

As you prepared the marketing budget for 2021, trade shows probably put a big question mark on your plan...

We sat late last year discussing this particular item while preparing our 2021 budget.

Trade shows hit a huge speed bump with all the restrictions caused by Covid-19. We just didn't know if people were going to attend or if exhibitors would participate. In talking to partners and customers we found that this was a variable that was up in the air.

Web Guiding Fundamentals - Why We Need Web Guides

A customer once asked us why would you need web guiding on a brand new machine?

Their point of view was that the machine was state of the art, the web guide didn't move at all during operation, and they didn't see any problems with their materials. Well, our answer was that there are four main reasons why any converting line requires web guides.

Web Guiding Upgrade Applications

Web Guiding Upgrade Applications

Imagine running a converting operation that has multiple converting lines. Each of these lines has been in operation for at least 20 years. You have invested in many improvements to the line, but are now faced with aging web guiding systems that are starting to fail.

At first, you manage to work with the deficiencies they have.

Servo Center Servo Installation

The servo centering is a term used to indicate the middle or center position of a web guide mechanism. For an intermediate web guide this would be the position where the web guide mechanism would be aligned with the rest of the machine so that idle roller(s) on the web guide would be parallel to the other fixed idle rollers on the machine. With terminal guides this would usually correspond to the middle of the stroke of the unwind/rewind carriage.
