Description
7 ~6 This invention relates to a deposition process using intaglio printing plates and of the type in which the material to be applied by deposition is injected through passages passing through the plate to a recessed or intaglio design on the printing surface of the plate.
The general object of this invention is to enable material to be applied on a sheet on both faces simultaneously in a single printing operation.
This is achieved by using intaglio printing plate apparatus in accordance with the invention which comprises in combination two intaglio plates attached to the top and bottom press platens of the apparatus, respectively. One of the plates is formed with passages passing through it for injection of printing material to the recess and the other with air bleed holes leading from the recessed design to atmosphere through appropriate air bleed/restrictor devices. The sheet materlal to which material is to be applied is then formed with holes of appropriate size and position to enable the material to be printed to flow from the recess in one plate through the holes in the sheet to fill the intaglio recess in the other plate. The sheet may thus be printed on both sides simul-taneously in one stroke of the printing press, the applied material filling the feed holes in the sheet.
The recessed design in one plate may be a mirror image of that in the other plate.
The material to be applied may be injected or forced through either the top or bottom printing plate using injector or pump units and if desired a number of differing materials ~S
~ " 1.
I
and colours may be applied simultaneously. As the air in the recessed designs in the top and bottom plates has to be re-moved it is convenient for the plate opposite to that attached to the injector units to be provided with air bleed holes preferably controlled by bleed/restrictor device(s) so that air can bleed out through the plate but cannot be sucked back into the recessed aesign.
The holes in the sheet on which material is to be applied may be positioned as required for effective performance.
These are best located at least at points of change of direction of the design to be applied where there is maximum resistance to flow.
The holes should be big enough to allow flow there-through of the material to be applied when this material is under pressure but small enough to prevent material flowing through the holes under gravity when for example the deposition operation is finished and the sheet material is lifted from the lower plate. As an example the feed holes may be from 10-30 thousands of an inch in diameter.
The bleed/restrictor device may comprise a member to be secured to the "bottom" printing plate and formed with passages to communicate with the air bleed holes in the "bottom"
plate. The holes in the plate are preferably relatively small e.g. from 0.040" to 0.005" in diameter (preferably 0.020") and provide flow restriction and in this case the passages in the member will have a sufficiently large cross-section to allow flow of applied fluid and entrapped air. ~lternatively well-known non-return valve means may be provided for example that described in the specification of our co-pending Canadian application 218,961.
The process in accordance with the invention has been found to be particularly useful for applying sealant material 71~
onto the top and bottom faces of gas}cets. Use of the process for this purpose halves the time and cost of depositing coat-ings on double-sided gaskets and avoids the necessity of having to cure the gasket twice (to set the sealant or coating material).
The invention will now be further described by way of ~xample with reference to the accompanying drawings in which:-Fig. 1 is a schematic view of intaglio printingapparatus adapted for the process of this invention.
Fig. 2 is an exploded cross-sectional view of an intaglio die plate used in the process of the invention.
Fig. 3 is a cross-sectional view of the "bottom"
printing plate used in the process of the invention attached to one embodiment of bleed air flow control device; and Fig. 4 is an exploded perspective view corresponding to Fig. 3.
Referring to Fig. 1, an upper intaglio plate 10 for depositing material in a pattern is supported from an upper support 12 mounted on an upper press platen 13. The press platen 13 cooperates with a lower press platen 14 which in turn supports a lower or bottom intaglio plate 16 and a bleed air flow control device 18. The sheet on which material is to be applied is placed between the plates 10 and 16. In the specification, the material to which material is to be applied will be described as a sheet of paper but it will be understood that the invention is applicable to any material to which a design is to be applied whether or not of paper. For example it may be a sasket to which a sealing compound is to be applied.
In the apparatus of Fig. 1, paint, sealing compound, 3~ or other applied fluid to be printed, is injected through the printing plate 10 by a plurality of injector units 20, three such units being illustrated in the drawings for applying three 7~6 different colours or types of compound if desired, or, alter-nati~ely each may apply a similar compound. Each injector unit supplies fluid to one intaglio recess in the face of the plate.
The injector units 20 are each supplied from a cor-responding fluid reservoir 22. Each injector unit 20 is con-nected to a corresponding one of the reservoirs 22 by a flexible conduit 24 which conducts fluid from the reservoir to the inlet of the injector. I~hile the reservoirs 22 may be under pres-sure, preferably the feed from the reservoirs 22 is a gravity feed.
The injector units may each comprise a piston which works as a pump so that when the platens 13 and 14 are moved together material in the injector is forced against and through the die plate 10.
Referring to Figure 2 the intaglio printing plate 10 is formed with passages 26 (only two of which are shown for clarity) passing through its thickness and communicating with a recessed design 28. The injector or pump units 20 are con-nected to the passages to force the material to be applied through the plate into the recess.
The intaglio printing plate 16 which is similar to the plate 10, is connected to the lower platen 14 of the print-ing press and the recessed design 30 is a mirror image of the design 28 of the upper plate 10, the plates 10 and 14'being aligned.
The sheet material e.g. gasket material, to be printed is illustrated at 32 and is formed with a number of feed holes 34 passing through it.
On operation cf the press sealant material is fed through the holes 26 into the recess 28 of the top plate and sealant material is applied to the top surface of the gasket 32 at those places where an additional height of sealant is B 5 _ .
~, .
required, sealant material then passes throuyh the feed holes 34 and into the recessed design 30 of the lower printing plate 16. Sealant is thus also applied to the bottom surface of the gasket 32 in the same operation.
The air from the recesses in the two plates and in the feed holes 26 and 34 bleeds out through the lower plate 16 through air bleed holes 36.
These bleed holes have a diameter of between 0.040"
and 0.005" preferably 0.020" so as to restrict the air flow whilst providing a reasonable exit passage. The holes com-municate with passages 38 in the bleed air flow control device 18, the passages 38 leading to a main exit passage 40 which is open to atmosphere at each side of the plate (see Figures 3 and 4). This arrangement provides restriction to flow through the holes 36 but the passages 38, 40 are of sufficient size to allow unrestricted flow of excess fluid and entrapped air. The material of the control device 18 should be incompressible, dimensionally stable and resistant to the fluid to be applied. Steel and "Tufnol" (RTM) have been found to be suitable.
The general object of this invention is to enable material to be applied on a sheet on both faces simultaneously in a single printing operation.
This is achieved by using intaglio printing plate apparatus in accordance with the invention which comprises in combination two intaglio plates attached to the top and bottom press platens of the apparatus, respectively.
