1. A bottle centering device for a capping machine for caps made of compressible material, wherein said bottle centering device comprises:
a support structure associated with a compression box of a capping machine at a cap compression seat, and which defines a through opening for passage of a compressed cap and a cap insertion punch of said capping machine, said support structure being mountable on said compression box so that said through opening has a central axis axially centered on said cap compression seat;
bottle centering means associated with said support structure and defining an invitation seat which defines a central through opening, is configured for engagement by a mouth of a bottle to be capped and is shaped to guide said mouth towards said through opening axially aligning said mouth with the central axis of said through opening;
an annular sealing gasket which is placed between the through opening and said invitation seat and is coaxial to the central axis;
wherein said bottle centering means comprise a plurality of pieces which are angularly distributed about the central axis of said through opening and each of the plurality of pieces defines with a respective shaped head a portion of said invitation seat, wherein the pieces of said plurality of pieces are radially movable with respect to the central axis to vary radial dimensions of said invitation seat and of said central through opening.
