Abstract: A device for testing a connection of a guarantee strip of a security seal of a closure lid having a lid main body, which device comprises a driver element for gripping the guarantee strip and a stop element for the lid main body. The driver element and the stop element are movable relative to each other such that a tear-off force can be exerted on the guarantee strip. The device also comprises a force-measuring device, for measuring the tear-off force during the relative movement of the guarantee strip and the lid main body, and a separating device for severing the guarantee strip after it has been tom off from the lid main body. The device can be operated in a fully automatic manner and can be integrated in a system for producing closure lids having guarantee strips.

Abstract: The invention relates to a device (100) for testing a connection of a guarantee strip (3.1) of a security seal of a closure lid (1.1) having a lid main body (2.1), which device comprises a driver element (180) for gripping the guarantee strip (3.1) and a stop element (780) for the lid main body (2.1). The driver element (180) and the stop element (170) are movable relative to each other such that a tear-off force can be exerted on the guarantee strip (3.1). The device (100) also comprises a force-measuring device (171), for measuring the tear-off force during the relative movement of the guarantee strip (3.1) and the lid main body (2.1), and a separating device (191, 192) for severing the guarantee strip (3.1) after it has been tom off from the lid main body (2.1). This allows the guarantee strip (3.1) to be severed and thereby results in a considerable simplification of the removal of the guarantee strip (3.
