Gripping assembly for capping head for the application of caps on containers or bottles

A gripping assembly (10) of a cap (50) for a capping head (30) for the application of caps on containers or bottles, comprising a hollow body (11) longitudinally extending along a vertical axis (A) and internally defining a receiving and retaining seat (12) for the cap, the receiving and retaining seat (12) being delimited at its lower end by an inlet mouth (13) for the introduction of the cap (50), inside the hollow body (11) there being housed an ejector member (16, 16′) that is free to axially slide, wherein the gripping assembly comprises a suspension member (21) made of magnetic material or magnetizable material, and in that the ejector member (16, 16′) carries at least one first magnetic element (20) suitable to magnetically interact with the suspension member (21) in order to determine a suspension condition of the ejector member (16, 16′), the magnetic interaction between the first magnetic element (20) and the suspension member (21) being such that the suspension condition is determined only when said ejector member (16, 16′) is brought in close proximity of or in contact with the suspension member (21).
