Definitions
- the invention relates to a method for closing and / or sealing openings, cavities or gaps, such as result from the application of printing plates to forme cylinders, in particular in the region of the end or edge sections of the printing plates, by means of a sealing or sealing compound.
- the method according to the invention is particularly suitable for closing and / or sealing such openings, cavities or gaps in intaglio printing plates applied to forme cylinders.
- rotary printing formes For the production of rotary printing formes, it is known to wrap form cylinders with flat printing plates and to fasten them to the form cylinders in a suitable manner, for example by gluing magnetically or mechanically by means of suitable holding and clamping elements.
- a suitable manner for example by gluing magnetically or mechanically by means of suitable holding and clamping elements.
- only one printing plate or several printing plates can be applied one behind the other and / or next to one another on the surface of a forme cylinder.
- This method for producing rotary printing forms is becoming increasingly important, especially in rotogravure printing, because of the simple and cost-saving production and handling of gravure winding plates.
- the partial pressure winding plates are preferably applied to the form cylinder by folding one or both of their end sections and hooking these non-edged areas into a groove of the forme cylinder provided for this purpose while simultaneously tensioning the gravure winding plate.
- Such openings or gaps which form when applying printing plates to forme cylinders have to be closed in a suitable manner in order to prevent penetration of printing ink, which may result, for example, in detaching the adhesive of the printing plate on the forme cylinder or, in particular in gravure printing, injecting the printing ink and unwanted impression of the column can lead, and also to ensure a smooth squeegee run and thereby prevent damage to the squeegee and printing form surface.
- Also on the forme cylinder end faces can between the forme cylinder surface and the side areas of the applied printing plate or between the printing form surface and the printing cylinder provided laterally, limiting the printing surface metal rings, as is usually the case in rotogravure printing. Openings and gaps are created that must be sealed to prevent printing problems from penetrating ink or for other reasons.

Sealing and / or sealing quickly and effectively with little effort, while avoiding the disadvantages known from the prior art, so that an all-round uninterrupted printing form surface is obtained which corresponds to the mechanical and withstands chemical stresses.
- the invention accordingly relates to a method for closing and / or sealing openings, cavities or gaps which are formed when printing plates are applied to forme cylinders, by means of a sealing or sealing compound, which is characterized in that it is used as a sealing or sealing compound a viscous, pasty mass at room temperature based on a dispersion of a solid, powdery, highly fluorinated olefin polymer in an inert, low-volatility, organic liquid is used.
- the method according to the invention can be used with printing plates of all types applied to forme cylinders, for example high-pressure and flexographic printing plates, it has proven to be particularly favorable and advantageous for gravure printing plates applied to forme cylinders.
- the sealing or sealing compounds to be used according to the invention the printing plates can not only be held and fixed on the forme cylinders in any desired position, it also prevents the penetration of even thin-bodied printing ink into the openings, cavities or gaps mentioned the resulting disadvantages prevented.
- the method according to the invention is suitable for closing and / or sealing any kind of openings, cavities or gaps in the case of printing plates mounted on forme cylinders, it is particularly suitable and can be used without problems and advantageously when closing and / or sealing small or narrow gaps, joints, other openings, spaces and the like.
- the sealing or sealing compounds to be used according to the invention are viscous, rigid, pasty dispersions of solid, powdery, highly fluorinated, preferably perfluorinated, olefin polymers in inert, low-volatility, organic liquids at room temperature.
- Highly fluorinated olefin polymers are both highly fluorinated homopolymers and highly fluorinated copolymers of olefins, in particular of ethylene and propylene, and also highly fluorinated olefin polymers which contain ether groups in the main polymer chain.
- the dispersions to be used according to the invention contain solid, powdery homopolymers or copolymers of highly fluorinated, in particular perfluorinated, ethylene or highly fluorinated, in particular perfluorinated, propylene. These include in particular the polytetrafluorethylene, polyhexafluoropropylene and tetrafluoroethylene-hexafluoropropylene copolymers.
- the solid, powdery, highly fluorinated olefin polymers contained in the dispersions to be used according to the invention are finely divided and, in addition to fluorine, may also contain to a lesser extent other halogen atoms, in particular chlorine atoms.
- the solid, powdery, highly fluorinated olefin polymers are preferably perhalogenated, in particular perfluorinated.
- the viscous, pasty dispersions to be used as sealing or sealing compound according to the invention contain, as a further component, one or more inert, low-volatility organic liquids which act as dispersants for the solid, powdery, highly fluorinated Olefin polymers act.
- inert, low-volatility, organic dispersing liquids are, for example, high-boiling fluorocarbon oils, fluorinated polyether oils, silicone oils or fats or fluorosilicone oils.
- the inert, organic dispersing liquids are generally low-volatility oils, but they can also be greases.
- the inert, low-volatility, organic dispersing liquids are: the corresponding, known fluorinated hydrocarbon oils; highly fluorinated, preferably perfluorinated, polyalkylene ether oils, preferably those polyether oils which are composed of recurring oxyperfluoroalkylene units of the formulas -CF2-O-, -C2F4-O- and / or -C3F6-O-, as described, for example, in DE-A-2 633 736 or are commercially available under the brand name FOMBLIN; Silicone oils or fats, for example of the type of polysiloxanes, such as polyphenylmethylsiloxane, or of the type of reticulated silicone polymers, for example methyl silicone polymers of oily or fatty consistency; as well
- the dispersions to be used according to the invention can be prepared in a conventional manner known per se by intimate mixing, for example stirring or kneading, of the individual components.
- the solid, powdery, highly fluorinated olefin polymers and the inert, low-volatility, organic dispersing liquids are selected according to type and amount and coordinated with one another such that a stable dispersion of the solid, powdery, highly fluorinated olefin polymers in the inert, low-volatility, organic dispersing liquid is produced and this dispersion has a stiff, paste-like consistency at room temperature and is viscoplastic so that it can be deformed under the influence of pressure and shear force, but is not self-flowing.
- the dispersions to be used according to the invention are usually solvent-free and the weight ratio of powdery, highly fluorinated olefin polymer to the inert, low-volatility, organic dispersion liquid is in the range from about 3: 7 to 6: 4.
- dispersions which are particularly suitable as sealants or sealing compounds in the process according to the invention are paste-like, rigid, viscous-plastic dispersions of powdered polytetrafluoro ethylene in perfluoropolyalkylene ether oils of the type mentioned above in a polymer: oil weight ratio of about 35:65 and paste-like, stiff, viscous dispersions of powdery polytetrafluoroethylene in silicone oil, for example polyphenylmethylsiloxane, in a polymer: oil weight ratio of about 1: 1.
- the viscous, pasty sealing or sealing compounds to be used according to the invention adhere well to metallic and plastic surfaces, so that when they are used according to the invention when closing and / or sealing openings, cavities or gaps in the case of printing plates mounted on forme cylinders, a stable connection in the closed or sealed areas.
