Abstract: A device for the cooling and extraction of preforms for the manufacture of plastic containers, including at least one grip assembly which forms a number of receptacles for respective preforms and a component for transferring the preforms that are still warm from an injection molding device to the grip assembly, and a cooling and extraction assembly which includes a cooling plate supporting a number of cooling channels. The cooling and extraction assembly includes an unloading plate which is arranged on the opposite side of the grip assembly with respect to the cooling plate, and supporting grip bodies which can be moved on command in order to pass through the cooling plate so as to engage selectively, with the cooling plate in the closer position, with a respective preform in order to allow its extraction from the respective receptacle.

Abstract: A device for printing a closure device for containers includes a first body and a second body each of which has a respective relative positioning element configured at least in a step of use of the closure device, to be arranged and/or oriented with respect to each other in a predetermined position. The printing device includes a supporting device for at least one of the bodies, a device for detecting the position or orientation of the relative positioning element of the body supported by the support device, and a device for digital printing of at least one portion of the body supported by the supporting device in order to perform a printing operation in a predetermined position and/or with a predetermined orientation with respect to the position and/or orientation of the respective relative positioning element.
