Claim 0:
1. A capping machine for caps made of compressible material, the capping machine comprising:
a compression box;
one or more compression units, each of the compression units being housed in a cavity made in said compression box and defining a cap compression seat;
a cap insertion punch for each compression unit;
a bottle centering device for each compression unit,
wherein each bottle centering device defines an invitation seat for centering a mouth of a bottle to be capped on a central axis and is mechanically associated with said compression box at a housing seat on a lower face of said compression box and is open on said cavity, said bottle centering device being mounted on said compression box with the central axis of said invitation seat axially centered on the respective cap compression seat;
wherein said capping machine comprises a fastener for removably retaining each bottle centering device in a respective housing seat,
wherein said fastener comprises for each bottle centering device at least one movable engagement element which is movably associated with the lower face of the compression box to move between:
a locking position, wherein said at least one movable engagement element interferes with the respective bottle centering device creating an undercut at said housing seat to retain the bottle centering device inside said housing seat, and
an unlocking position, wherein said movable engagement element is free from interfering with the respective bottle centering device to enable the bottle centering device to freely engage or disengage the housing seat.
