A good paper or film roll end is simple to define. The roll has right shape and size. It is not too hard or soft and there are no visual defects. The roll must work well on converter. However, it is often difficult to meet these requirements and avoid problems before sending tons of bad rolls into the broke or having customer claims. Typical problems are poor starts, core offsets, offsets and interweaving, dished and telescoped rolls etc. Good measurements are the key point.
Roll End Measurement
There is a line laser pointed to the end of the roll and camera is used to detect when the vertical line is in the middle of the roll. Based on horizontal shape of the line the shape profile of the roll end is calculated. The Tapio REP roll end profiler measures rolls online when they are moving on conveyor without stopping rolls to a certain measurement position.
