This test equipment is intended to assess the strength of the bond between the sole and upper at the toe and heel area of the lasted margin of completed footwear. This non-destructive test is suitable for factory and laboratory use and mainly applicable to stuck-on or moulded-on constructions with an extended sole edge.
This machine is equipped with a 100 kg load cell that acquires the force exerted at the toe or heel, this force is then real time reported to the operator by means of a digital display. An electronic system allows to choose a target load anc once it is reached a buzzer and luminous alarm is activated at the same time to alert the operator.
A thin rectangular steel plate with an arc shaped cut-out is connected to a force measuring system. The steel plate 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. The footwear is then rotated by hand about the fulcrum and the force applied by the steel plate which necessary to separate the upper from the sole is measured. The test may also be non-destructive by applying a set point maximum force and checking for failure of the bond.
