TEST APPARATUS

摘要

A test apparatus for leak-testing waterproof footwear comprises a support post (40) and an inflatable collar (2, 43) slideably mounted thereon. A foot (48) is attached to the lower end of the post for abutting the inside sole of the footwear and spacing the collar the correct distance therefrom to seal the entrance to the footwear. The collar is inflated to seal the interior of the footwear, which is then pressurised with air. Any air leaks are detected by immersion in water and observation of bubbles, or by using a sonic probe. Almost complete footwear items can be tested, usually before application of the outer sole.
