Paper Internal Bonding Strength

Designed for determining the Internal Bonding Strength of Paper, Paperboard and Laminates, by measuring the average energy, in thousands of foot pound required to delaminate the specimen in two piles, as described reference standard TAPPI T-569.

Dual capacity pendulum of 0 - 0.25 FT/LB and 0.1 - 0.5 FT/LB Readings directly on calibrated scale, The five number specimen preparation unit, which will allow for variations of specimen thicknesses, with different clamping pressures on the specimen from 50 to 200 PSI.

Standard calibration sliding weight with sample holder
Double side adhesive tape width 1a
Made of Heavy cast iron base with built-in leveling device pressure Adhesive tape dispenser integral with base and L shape sample holder

A Stationary Anvil and separable platen which the pendulum strikes at the same point for each test

Sample Size 1a x 1a
Measuring range 0-0.25 Ft/lb, 0-1.05 Ft/lb, Clamping pressure 50 to 200 PSI

A pendulum of dual capacity and free to swing on ball bearing in dust proof bearing assembly, The range changing weights are available to select the pendulum capacity.

A mechanism for holding the pendulum in raised position with a provision instantaneous release. A plexiglass peak pointer to register the maximum arc, enough which the pendulum swings when release
The scale is calibrated in thousands of a foot pound in both ranges, with a reference point for calibrating the pointer in free swing to compensate for friction during swi
