In terms of protecting the integrity of the products you offer, investing in a quality seamer is a critical step. However, while an important step, operating the seamer properly is equally important. A seamer that isn't functioning correctly can lead to issues with the integrity of the seal, which can cause several different problems. This is particularly the case when it comes to an issue with the rollers. Being able to recognize a problem can help.
A common problem that can arise with seamers is missed, or incorrect, roll placement. The issue arises when one of the rolls is not properly aligned with the chuck. When this issue occurs, this causes wrinkling around the seam line which can lead to leaking and also allows air to get inside the container, which can affect the quality of the product.
This problem typically occurs when the operator overly tightens the roller during operation. Provided you catch the problem fast enough, you can reposition the roller without causing any major problems.
Poor Roll Design
Another common problem is a poor roll design. This problem will generally surface beginning the very first time you use the seamer, quickly alerting you of a problem. It often produces a problem in the form of misshaped seams. In terms of a tight seam, a poor roll design can still produce this benefit.
However, in terms of quality and appearance, it does leave much to be desired and will likely fail much faster than a seam rolled on a proper design. Since this is typically related to a design flaw with the machine, it often rarely occurs, but it is still something to look for.
A damaged roll is also a problem to look out for as it can negatively affect the quality of seams you are able to produce. With regular wear and tear, or because of prolonged misplacement, the rolls can start to show signs of wear.
While you can't always see this wear from the outside, it does surface in the form of seam lines that are rigid and abrasive and somewhat appear like they've been through a grinder. Seams in this condition are more likely to crack and fail. Replacing the rolls is often the best solution.
If you suspect a problem with the rolls on your machine, make sure you are reaching out to a service technician for a repair or replacement. The faster you have your machine looked at, the better.
