Abstract

The tightness of the sealed package is monitored by a process strategy and a finishing system, which makes use of and incorporates a first system section incorporating at least one vessel and a pressure cell. The second system incorporates a closed measuring chamber and a strategy for adjusting the pressure of the system section via the first system section. The first system is pressurized first to obtain a preset pressure, which may be either above or below atmospheric pressure. Then the first and second system sections are then introduced into contact to establish a second pressure for the first and second system sections. Staple in sealed package The lack of sample in the measuring chamber and the leakage in the measuring chamber can be detected with the help of the pressure cell. For the detection of anything other than the primary leakage, the first and second systems are separated, and the differential pressure cells detect the pressure of the first and second system segments with sufficient timing for Detects differences between the first and second system segments to detect whether the woven package is leaking or not.
