An apparatus for inspecting the integrity of a seal of a package that includes a container and a seal membrane carried by the container. The apparatus comprises a conveyor configured to move the sealed package along a path and including a vacuum plenum section configured to create a sub-atmospheric pressure that is applied to the seal membrane of the sealed package as the package moves through the vacuum plenum section. The apparatus further comprises an imaging sensor configured to generate one or more images of the seal membrane following the application of a sub-atmospheric pressure thereto at the vacuum plenum section. The apparatus still further comprises an electronic processing device configured to process the one or more images of the seal membrane generated by the imaging sensor, and to evaluate the integrity of the seal of the package based on the one or more images.

Method and machine for generating packages from a continuous film. In the method, the quality of the seals formed when generating packages on the film is furthermore verified, and to that end, a chamber is closed around an area of a film tube comprising an actuation area, a transverse cut and a transverse seal on each side of the transverse cut being generated in the actuation area. For the verification, pressure in the chamber is reduced, a property of the fluid present in the chamber or in the part of the tube present in the chamber is detected, and the quality of at least one of the seals present in the chamber is determined depending on the detection.

A device, system, and method for detecting a leak (and determining the leak rate of the leak) for equipment, particularly generators, the device including a main body connected to the tested equipment and to an air supply source, wherein the main body includes a number of stages each having a valve and orifice such that flow of air through the independent stages is selectively controllable, where a change in the differential pressure recorded during flow of the air through a particular stage indicates a leak, and wherein the differential pressure recorded can be used to calculate the rate of leak in the equipment.

A seal testing apparatus for testing the integrity of a seal in the packaging of vacuum packed product and a method of testing seal integrity. The apparatus includes a mechanical gripper that grips a portion of the packaging and is urged away from the packaging. A sensor monitors the movement of the gripper relative to the vacuum packed product and an evaluator compares the sensed movement of the gripper with an acceptable profile and accepts or rejects the product based on the comparison.

A method and kit for detecting leaks in an aircraft wing (5) including: providing an aircraft wing structure having at an outboard end a wing tip (11) and at an inboard end a wing root (9) and at least one rib disposed between the wing root (9) and the wing tip (11), there being in a first rib section (13) of the wing (5) a first rib (19) closest to the wing root (9); placing a gas-impermeable bladder (43) over the wing root (9); forming a gas-tight circumferential seal between the bladder (43) and an outer surface of the wing (5) in the first rib section (13); introducing a gas into the aircraft wing (5); and sensing for leaks in the aircraft wing (5).
