Claims
- 1. A machine for decorating containers or similar articles comprising:
- a supporting structure;
- a rotatable shaft coupled in the supporting structure, to rotate over its own axis with an intermittent movement;
- a first plurality of transporting stations and a second plurality of transporting stations, said stations being arranged in coincidence one in front to the other and having a predetermined distance therebetween, said first and second transporting stations being connected to said shaft to rotate together with said rotatable shaft;
- driving means connected to the rotatable shaft, said rotatable shaft and said first and second transporting stations being rotated together by means of the driving means; and,
- screen printers respectively located for defining at least two printing stop stations located in the same plane as the surface of the container to be decorated, each printer screen being located between each first plurality of transporting stations and each second plurality of transporting stations, each screen printer being adapted to be alternately positioned so that it decorates the surface of the container to be decorated or so that it does not decorate the surface of the container to be decorated, the improvements characterized by comprising:
- at least two first holding means for each one of the first plurality of transporting stations, for holding the bottom of at least two containers; and,
- at least two second holding means for each one of the second plurality of transporting stations, for holding the neck of at least two containers, said first and second holding means being arranged symmetrically in a position one in front of the other, said first and second holding means being adapted to receive, support and release the container from a loading position to an unloading position of the machine;
- said screen printers including structure to allow printing on one or more of said at least two containers, said printing comprising at least two decorating impressions within less than one complete revolution of the first and second plurality of transporting stations, each of said at least two decorating impressions being received at a different one, of said at least two printing stop stations than the remainder of said at least two decorating impressions, the screen printers being adapted to allow at least two containers selected from said at least two containers to each receive a decorating impression simultaneously at one or more of said at least two printing stop stations, the screen printers being further adapted to allow one container selected from said at least two containers to receive a decorating impression at one or more of said at least two printing stop stations, the screen printers being further adapted to allow one or more containers selected from said at least two containers to receive a decorating impression at one or more of said at least two printing stop stations.
- 2. A method for decorating containers comprising the steps of:
- a) feeding a plurality of containers to be decorated from a conveyor toward transporting stations of a decorating machine;
- loading simultaneously at least two containers between a first plurality of transporting stations and a second plurality of transporting stations, said stations having a predetermined distance therebetween, each first plurality of transporting stations including at least two first holding means for each one of the first plurality of transporting stations, for holding the bottom of at least two containers, and each one of the second plurality of transporting stations including at least two second holding means for each one of the second supporting members, for holding the neck of at least said two containers, said first and second holding means being arranged symmetrically in order that at least two containers be simultaneously printed with a single printer screen;
- c) rotating the transporting stations with an intermittent movement, making the containers to coincide with a screen printer provided for each of at least two printing stop stations of the decorating machine, each screen printer being adapted to be alternately positioned so that it decorates the surface of a container to be decorated or so that it does not decorate the surface of a container to be decorated;
- d) decorating one or more of said at least two containers with a printer screen for each transporting station, each printer screen being adjusted in accordance with the surface of the containers to be printed, each container being rotated over its own axis in order to be decorated by each printer screen, each container receiving at least two decorating impressions from at least two of said screen printer, each of said at least two decorating impressions being received at a different one of said at least two printing stop stations than the remainder of said at least two decorating impressions, the screen printers being adapted to allow at least two containers selected from said at least two containers to each receive a decorating impression simultaneously at one or more of said at least two printing stop stations; and,
- e) unloading said at least two containers recently decorated from the transporting stations to said conveyor after less than one full rotation of the transporting stations between said loading and said unloading of said at least two containers.
