Abstract: A capping machine for caps made of compressible material includes a compression box and compression units, each being housed in a cavity in the compression box and defining a cap compression seat. A bottle centering device is associated with each compression unit and is mechanically associated with the compression box at a housing seat on a lower face. The capping machine includes a fastener for removably retaining each bottle centering device in its respective housing seat. The fastener includes for each bottle centering device a movable engagement element movably associated with the lower face moveable between: a locking position, wherein the movable engagement element interferes with the respective bottle centering device creating an undercut to retain the bottle centering device inside the housing seat; and an unlocking position, wherein the movable engagement element does not interfere, allowing the bottle centering device to freely engage or disengage the housing seat.

Abstract: A bottle centering device for a capping machine for caps made of compressible material includes a support structure, associated with a compression box at a cap compression seat and defining an opening for passing a compressed cap and a cap insertion punch. The support structure is mountable on the compression box so that the through opening has a central axis axially centered on the cap compression seat. A bottle centerer defining an invitation seat and a central through opening is configured for engagement by a bottle mouth and is shaped to guide the mouth towards the through opening axially aligning with the central axis. The bottle centerer includes pieces angularly distributed about the central axis and each partially defining a portion of the invitation seat. The pieces are radially movable with respect to the central axis to vary radial dimensions of the invitation seat and the central through opening.

Abstract: The present invention concerns a motion transmission group for capping heads for screw caps. This group comprises a device for applying in use a predefined axial load to means of axial engagement of the caps which a capping head associated in use with said group is provided with. The device comprises at least one axially pre-loaded compression spring so as to generate in use this predefined axial load. The device is separable from the main structure of the transmission group as a single body, with the aforesaid at least one spring maintained associated with a support structure of the device in pre-loaded condition by means of two axial positioning portions to allow the replacement of the device with a structurally similar device, but suitable to generate in use a different axial load.

Abstract: The present invention relates to a screw transport apparatus for bottles, comprising: —a support structure, which extends longitudinally between a bottle inlet 1a and a bottle outlet 1b of the apparatus, and—a spiral-shaped helical body, which is associated with the support structure and extends axially parallel to the support structure between two own axial ends. The above spiral-shaped helical body can be rotated on itself about its own longitudinal axis to move bottles in cooperation with the support structure. The spiral-shaped helical body comprises at least two spiral-shaped seats, which extend coaxially between the two axial ends. They are angularly offset from each other and differ from each other by the shape and/or dimensions of the relative bottle housing compartment defined by each of them. The two spiral-shaped seats are intended to be used alternatively to the other for the transport of bottles having different shapes and/or dimensions.
