L&W Compressive Strength Tester STFI code 282 measures the compressive strength of liner and fluting according to the SCT- method. Compressive strength determines the stacking ability of corrugated boxes. The aim is to produce strong boxes, and use a minimum of raw material. Ultra precision clamping unit: Benefits
a) an improved measuring unit designed for higher accuracy and reproducibility between measuring units b) all important tolerances has been tighten so they surpasse the requirement from ISO and Tappi c) the new design leads to less wear of critical parts, longer life time, simplifies maintenance work, and is less sensitive to build up fibres and dust
L&W Micrometer code 251 gives precise and exact thickness measurements corrugated board. Thickness (caliper) is an important characteristic that affects bending stiffness. Controlling thickness uniformity means producing printing paper that performs well in the printing press. The automatic start allows the user to keep both hands on the sample to precisely place the sample in the measurement area. Benefits a) Auto-start, a photocell detects the presence of a sample and automatically initiates a measurement sequence, thus allowing hands-free operation
b) Auto-cycling function that permits the continuous cycling of the upper pressure face to facilitate representative and continuous measurements c) Adaptive lifting height optimizes the height adjustment of the upper pressure face to allow whole series to be measured as quickly as possible d) Consistent result, due to high quality manufacturing standards (hardened and polished stainless steel)
