Differential Speed Measurement System for Flexible Packaging
Beta LaserMike introduces the LaserSpeed Differential Speed Measurement System at the Converting & Package Printing Expo 2012 (booth 644) to help converters of flexible packaging accurately control the web tension of product during production.
The system measures the differential speed of the web at two different locations without making contact with the product. It uses the LaserSpeed Length Differential Indicator (LDI) and two LaserSpeed non-contact laser encoders to monitor the two different line speeds, placed at two critical measurement points on the line. Since the LaserSpeed encoder measures the product itself and not the drive roller, slippage is not a problem. Speed measurements are captured with better than ±0.05 percent accuracy and 0.02 percent repeatability, enabling the converter to precisely monitor and control the required amount of tension on the web.
