摘要

The invention relates to an arrangement and method for gripping the mouth (5) of a hollow object on the inside of the mouth, and for sealing the mouth for seal testing. The arrangement comprises at least one gripping device, which includes a body part (1, 2) to which is connected a moving means (7) arranged to move with respect to the body part, around which moving means is arranged an intermediate piece to be inserted through the mouth of the hollow object, which comprises at least two gripping means (4). At the end of the moving means (7) is a spreading means (8) for spreading the gripping means (4) outwards, to provide a grip on the inside of the mouth of the hollow object. On the surface of the body part facing the mouth of the hollow object is a sealing means (9), in which is formed an aperture (10), through which the moving means (7) and intermediate piece extend, which gripping device can be brought close to the mouth (5) of the hollow object in such a way that the moving means (7) and the intermediate piece will extend inside the mouth (5). The outwards spreading movement of the gripping means (4) is arranged to take place by means of the spreading means (8) through the outward movement of the moving means 7 from the mouth and the bringing of the face of the mouth (5) of the hollow object into a tight attachment against the sealing means (9) is arranged to take place by continuing the said outward movement of the moving means (7) once the gripping means (4) have gripped against the inside of the mouth.
