摘要: Disclosed are a method and apparatus for testing the tightness of foil bags (10). In order to test (10), mechanical members used which act upon bag (10) in region cavity (15) formed above packaged goods. Testing rams (18) pushed against wall (16, 17) with given pressure. The depth impression is indicative airtightness ( 10). size can be reduced by clamping (26) and, as result, residual (25) next (26). Consequently, an increased pressure present within residiual cavity, that say facilitates testing.
