PAPERmaking! FROM THE PUBLISHERS OF PAPER TECHNOLOGY Volume 3, Number 2, 2017
L&W OptiTopo code 269 is an instrument for measuring surface roughness and predicting printability of paper. It is a faster, better and yet less expensive instrument compared to traditional optical methods for measuring surface roughness. The measurement method is developed by Innventia and has, for over a decade, proven to be an outstanding technique to assess the correlation between paper surface and print defects. Benefits a) Fast optical method – reports in a few seconds b) Comprehensive prediction of printability c) Extensive measuring area d) High-resolution CMOS camera L&W Cobb Sizing Tester code 146 measures the weight increase of a sample, when exposed to water for a given time. L&W Cobb Sizing Tester is also available in a special version with rubber gasket for corrugated board to avoid leakage. Benefits
a) Single handed operation b) Fast locking of the sample c) Couch roll is included
L&W Strip Punch code 108 provides you with precisely cut sample strips, which can be used in tensile strength tests, fracture toughness tests, compression strength tests, bending stiffness tests, or ring crush tests. Benefits a) Precision cutting of samples b) Easy to operate c) Sturdy model d) Feeding table for easy handling
