Roll design can help with eliminating web handling wrinkles
Wrinkles have been a major issue in web handling applications since the beginning of converting technology. While the root cause can vary, one solution for eliminating web handling wrinkles may be as simple as installing either of two specific types of rolls designed to address this challenge.
No two webs or web lines are exactly the same, which often makes identifying the root cause a process of elimination. MECA helps minimize the list of possible causes with two roll designs that focus on eliminating web handling wrinkles.
Our reverse taper roll, also referred to as a reverse crown roll, features a concave surface that has a larger diameter at the ends than in the middle. This design encourages the web to climb up to the high side of the roll, gently stretching out the web and thus eliminating wrinkles.
Use this checklist for eliminating web handling wrinkles
Identifying the root cause of web wrinkles often comes down to a relatively small number of variables that exist outside the influence of roll design.
When ordering, make sure to share details with your supplier such as the amount of web wrap, web tension (PLI), web width, maximum line speed, and any nip load (PLI). The MECA team can guide you through these questions.
