Digital Board Stiffness Tester Taber Type

Bench instrument that measures the bending stiffness of folding carton board and paperboard by deflecting a clamped specimen through a set angle. Used by mono carton converters and board mills for incoming board and run-to-run quality checks.

Specification

This Taber-type stiffness tester applies a controlled bending moment to a vertically clamped board strip and reads the resisting moment directly in gf.cm or mN.m. It helps carton plants confirm that board will hold shape on cutting, creasing and automatic packing lines. Results are repeatable between operators because deflection angle and clamp geometry are fixed.

Features

• Direct digital readout in gf.cm and mN.m with peak hold
• Motorised pendulum drive for uniform loading rate
• Interchangeable weights for low and high stiffness boards
• Precision specimen clamp with 0.5 mm spacing guide
• Auto-return and zeroing after each test
