LCD Rapid Sole Adhesion Tester 100kg Load Range

Product introduction

This testing machine is used to test the peel strength between the sole and the upper of the shoe. The principle is to clamp the finished shoe last on the testing machine, and peel off the sole and upper with a peeling knife. The force of the test peeling off the initial glue is the peeling force, and the peeling strength is calculated based on the width of the peeling knife.

Standards

Comply with GB/T3903.3, BS 1870, BS 4676, SATRA TM404 and other standards.

Technical parameters

Principle

A thin rectangular steel plate with an arc shaped cut-out is connected to a force measuring system. The arc shape is positioned on top of the extended edge of the sole of the test footwear at either the toe or heel. The wearing surface of the sole is brought into contact with a fulcrum which is a fixed distance from the center of the arc. The footwear is then rotated by hand about the fulcrum and the force applied by the steel plate which is necessary to separate the upper from the sole is measured . The test may also be non-destructive by applying a set maximum force and checking for failure of the bond.
