Roll Alignment Best Practice
Hi All,
New member here to the forums and look forward to joining in on topics and learning from all of you. But to start off I do have a question regarding roll alignment best practices for film machines and tolerances recommended for roller error. We are currently using VFFS baggers that seem to have quite a bit of error which we think is leading to film tracking issues. We just recently purchased a roll alignment laser and started getting a few readings and for rolls that are about 2-3 feet away from each other seem to have about a 0.25" offset error. I can't imagine this is conducive for film tracking so we are looking to try and re-align rollers to get them to a parallel state. I just wanted to gauge what a reasonable tolerance error is for a setup like this or if the current error we are seeing is even relevant on such a small scale as this (compared to most larger film machines). Feel free to ask any questions if what I presented wasn't quite clear.
Thanks
