Paper Tube Ply Bond Strength Tester

Peel and internal bond tester measuring the adhesion between spiral wound plies of paper cores and tubes. Used by core manufacturers to verify glue application and tube integrity.

Specification

A tube ply sample is bonded to metal blocks and pulled apart at right angles, and the maximum force per unit area gives the internal bond strength. It reveals under- or over-glued zones. The test is used to troubleshoot delamination in wound tubes.

Features

• Tensile loading at 10 mm/min
• Load capacity 2 kN
• Metal test blocks 25 x 25 mm
• Peak force and bond strength display
• Specimen press with double-sided adhesive
