Shoe Sole & Upper Shoe Peeling Strength Tester GT-KC41B

Introduction of Peeling Strength Tester

This Shoe Testing Machine To determine the strength of the bond between the sole and upper at the toe and heel area of the lasted margin of completed footwear. The method is mainly applicable to stuck-on or moulded-on constructions with an extended sole edge.

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.
