Explore Tapio articles on practical insights for paper, board, and plastic film production. In these articles, we cover common quality issues — like thickness variation and roll defects—and show how our measurement tools can make them visible. You’ll also find updates on the latest features and technologies from Tapio.
Reducing plastic film roll rejections with roll hardness profiling The Tapio RQP Live produces an instant high-resolution hardness profile. Alert limits for out-of-spec rolls allow for immediate flagging of problematic
How Tapio Analysis Helps Solve Barring Problems In paper and board production, calender roll barring is a significant problem which can lead to unscheduled maintenance breaks and visible defects in
How Product Variations can Cause Winder Vibration A winder–cutter is not an easy system to optimize. Changing web tensions, roll diameters, masses and rotational frequencies all interact, and the behaviour
Roll Hardness Profiles – What Can the Statistics Tell Us? Quality of rolls is not about appearance – it depends both on the rolled material and on how the roll
Optimizing paper and board machine CD profiles with Tapio Analysis In modern paper production, achieving an efficient and accurate cross-direction (CD) profile is critical for product quality and production cost
Locate problematic machine elements using Tapio MD Analysis In paper, board, and other continuous production processes where the product is formed by rolling or pressing, every rotation of any mechanical
Hidden defects in rolls: a closer look with Tapio RQP Live A paper, board or plastic roll may appear perfectly fine on the outside. The surface layers may seem to
Every mill knows the frustration of a “bad” roll — unscheduled downtime, customer complaints, wasted materials, and production delays. But what if you could detect roll defects before they cause expensive problems? The good news: you can. And it starts with understanding roll hardness profiles.
