Equipment for testing the watertightness of variety of manufactured articles, comprises upper and lower rotatable barrels with peripheral interfaces which engage with a testpiece placed between them

摘要

A testpiece (8) is located between a lower drum (2) and an upper drum (3). The lower drum is fixed in height and may be rotated by a motor (11) to bring a variety of interfaces (6,9) adjacent to the testpiece. The upper drum may be raised/lowered by jacks (19) and also rotated by a motor (12) to present various interfaces (10). The lower drum supplies air through an interface and the upper drum measures pressure to check watertightness
