Abstract: The present invention is referred to a method and a machine for decorating bottles or similar articles of the type that includes: a supporting structure; a rotatable shaft (12) coupled in the supporting structure, to rotate over its own axis with an intermittent movement; a plurality of transporting stations (14) connected to the shaft (12) to rotate together with the rotatable shaft (12); supporting members (16 and 18) for each transporting station (14), each supporting member (16, 18) being arranged to transport a bottle from a loading position to an unloading position of the machine; drive means connected to the rotatable shaft (12), the rotatable shaft (12) and the transporting stations (14) being rotated together by means of the drive means; and, a printer screen (PD) for each of the transporting stations (14), the screens (PD) being located toward and coinciding with a surface of the bottles to be decorated, the machine having at least two free transporting stations (14), one for the loading and another

Abstract: Hot molds are internally cooled by providing a plurality of cooling passages having first and second opened ends, in the body of said molds; a plurality of blowing heads, each of which having an inner flow convertor defining an inner anular chamber and a central suctioning passage, and is coupled to the first end of a corresponding cooling passage, in order to provide a tangential flow of cooling air to said cooling passage causing a swirl cooling current therethrough, which is accelerated by an air current that is suctioned through the suctioning passage of the blowing head, and which afterwards is exhausted through the second end of said cooling passage; and cooling air feeding means correspondingly coupled to each of said blowing heads, providing a flow of cooling air to said blowing heads.
