20080271631 | Placement and Removal Device of a Doctor Blade in a Printing Screen Cylinder - The invention relates to a placement and removal device of a doctor blade in a screen printing impression cylinder mounted on a printing machine. The device comprises a support fixed to the frame of the machine in the extension of the cylinder on which a slide is mounted in a manner that enables it to pivot about an axis parallel to the axis of said cylinder. The slide is provided for enabling a slider to be displaced only parallel to said axis. The slider is equipped with rapid assembling and disassembling means that interact with mating means on the doctor blade for permitting the doctor blade to be rapidly fixed to or removed from the slider. The slider is designed for enabling it, in a first limit position situated on the outside of the cylinder, to rise in order to remove the doctor blade and, in a second limit position inside the cylinder, to be placed in front of the working position of the doctor blade. In this position, by turning over the slide, the doctor blade is placed in or removed from the working position. | 11-06-2008 |
20080271854 | Stamping Cylinder - A cylinder for stamping planar substrates, such as sheets of paper comprises at least a pit with clamping means for holding a stamping medium on said cylinder, said medium comprising at least a row of stamps distributed along the medium. The medium is formed by a stamping plate or by stamping strips and said cylinder further comprises at least a supporting piece forming a bridge over said pit. | 11-06-2008 |

20100170408 | Cylinder Body for Orienting Magnetic Flakes Contained in an Ink or Varnish Vehicle Applied on a Sheet-Like or Web-Like Substrate - There is described a cylinder body ( | 07-08-2010 |
20100242753 | Screen Printing Press and Method - There is described a sheet-fed or web-fed screen printing press, especially for the production of banknotes and like securities, comprising an impression cylinder, a first screen printing unit cooperating with the impression cylinder for applying a first ink pattern onto successive sheets or web portions, at least a second screen printing unit cooperating with the impression cylinder for applying a second ink pattern onto the successive sheets or web portions, which second screen printing unit is located downstream of the first screen printing unit with respect to a direction of rotation of the impression cylinder, and an intermediate drying unit located between the first and second screen printing units. The intermediate drying unit is adapted to perform superficial drying of the first ink pattern applied by the first screen printing unit before application of the second ink pattern by the second screen printing unit, which superficial drying involves only the drying of an outer superficial portion of the first ink pattern. Preferably, the second screen printing unit is adapted to apply the second ink pattern in close proximity to the first ink pattern or at least in a partially overlapping manner onto the first ink pattern. | 09-30-2010 |
20110017393 | Method and Installation for Applying Foil Material Onto Successive Sheets - There is described a method for applying foil material ( | 01-27-2011 |
20110139362 | Method and Installation for Applying Foil Material Onto Successive Sheets - There is described a method for applying foil material onto successive sheets, especially sheets of securities. In a first step, individual sheets are transported in succession along a sheet transport path. In a second step, at least one continuous band of foil material is applied onto the individual sheets along a direction substantially parallel to a direction of displacement of the individual sheets, thereby forming a continuous flow of sheets linked to one another by the said at least one continuous band of foil material. In a third step, the said at least one continuous band of foil material is cut such that the continuous flow of sheets is again separated into individual sheets with portions of foil material remaining on the sheet. The cutting is performed at positions located on the sheets such that said portions of foil material remaining on the sheets do not extend beyond leading and trailing edges of the sheets. There is also described an installation for carrying out the above method. | 06-16-2011 |
