Test Method: SATRA TM404

Rapid sole adhesion test - for complete footwear

January 2020

SCOPE

This method is intended 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. The test is suited to quality checking at the end of the factory production line, between sole bonding and last slipping.

PRINCIPLE

A thin rectangular steel plate with an arc shaped cut-out is connected to a force measuring system. The arc shape cut out is positioned on top of the extended edge of the sole of the test footwear, containing a last, at either the toe or the heel. The wearing surface of the sole is brought into contact with a fulcrum which is a fixed distance from the centre of the arc. The lasted footwear is then rotated by hand about the fulcrum and the resulting leverage force (applied by the steel plate) required to separate the sole from the upper is measured.

The toe-test may also be performed non-destructively (e.g. on a factory production line) by applying a set maximum force and checking for failure of the bond.
