The SABOT and IRIST projects involve a broad
European consortia of shoemakers, shoe-industry research
associations and other research organisations, including academia
and companies such as AOS, from the UK, Spain, Portugal and Greece.
The overall aim of both projects, which attracted co-funding from
the European Union, was the improvement of the shoe-making process,
by improving quality thereby reducing early failures, customer
dissatisfaction, wastage of materials and cost.
The SABOT project was concerned with the shoe bottoming process, in
which the lasted upper is adhesively-bonded to the sole unit. The
failure of this bond is the single biggest problem in modern
shoemaking and accounts for the vast majority of customer returns.
The performance of this bond is dependent on a large number of
factors, including surface preparation, cement application, cement
temperature at the moment of bonding and the pressure applied to the
surfaces during bond formation.
During the SABOT project, quantitative information on the sole
bonding process and the interrelation of these important factors was
obtained for the first time. As a result, several improvements to
factory processes were made and enhancements to existing shoe-making
machinery were demonstrated. AOS's role in the project was to
develop instrumentation for monitoring the shoe-bottoming process
and to acquire the base dataset and, working with the other research
organisations, to develop and demonstrate process improvements. |
