Abstract: A method and relative apparatus for testing the tightness of a container closed by a membrane are described. The method includes steps of: submitting the container to a deforming action to increase the pressure inside the container; submitting the membrane to an abutting action to counteract the deformation of the membrane caused by the deforming action; maintaining the action of abutting the membrane at the same time as the action of deforming the container for a set period of time; interrupting the action of abutting the membrane at the end of the period of time; detecting at least one parameter related to a membrane profile when the abutting action has ceased; and comparing the at least one parameter related to the membrane profile with a predefined threshold to verify whether the tightness of the container is to be classified as defective.

Abstract: A support for transporting containers in a microwave inspection device, including a supporting body which can be moved along a feed path and at least two receiving seats connected to the top of the supporting body to be moved along said feed path, wherein said supporting body has two or more supporting portions (S1, S2) which are at least partly separated from each other by one or more openings and each carrying at least one respective receiving seat, said supporting portions (S1, S2) being connected or integral with each other in a lower region of the supporting body.

Abstract: A method for performing operations on items (A) transported along a manufacturing line including feeding a sequence of items (A) with respective resting portions along a first feed path onto a first transport surface, arranging a gripping assembly having a first gripping head and a second gripping head, picking up a first item (A) from the first feed path using the first gripping head, rotating the first item (A) around a first rotation axis (R1), performing at least one operation on the item (A) during the rotation thereof around the first rotation axis (R1), swapping the positions of the first gripping head and the second gripping head, resting the first item (A) on a second transport surface and releasing the first item (A), and picking up a further item (A) from the first feed path using the second gripping head.
