Definitions
- the subject of this invention is an application machine with magnetically effected squeegee pressure, whereby under the application machine both a printing machine, e.g. a flat or circular stencil printing machine, or also a full area, i.e. machine without any sampling process.
- the substrate on which the application is made is a so-called web, i.e. a flat structure, e.g. made of textile material, paper, plastic or the like; the substrate could e.g. can also be a carpet or other floor covering, wall covering or the like, a sheet metal sheet or a transfer belt.
- the application process takes place in connection with a relative movement between at least one application device built into an application machine according to the invention and the substrate.
- the element causing the application is pressed by means of magnetic force against the substrate or against the stencil and can either be a doctor blade, a doctor blade, a doctor knife or the like. be made of magnetizable material or possibly equipped with components made of magnetizable material.
- the object on which the present invention is based is to bring the material web (the substrate) in the application machine into the optimal flatness required for the application process. This was or is not possible according to the prior art known to date, because the substrate web in the application machine always sags more or less before or after the application device. This sagging of the substrate web affects the quality of the application process; this is particularly true for the application of magnetic doctor application devices in flat stencils. printing machines. In such printing machines, the application process takes place alternately in two opposite directions of movement.
- Magnetic table application devices in application machines are known in numerous design variants, so that their description is omitted here and the subject matter of this invention can be described below.
- the object of this invention is characterized in that in an application machine which is equipped with at least one application or squeegee device acting with magnetic force per se known and possibly also with a conveyor belt, at least one carrier tape or a profile strip is held at the ends or is clamped and equipped with at least one magnetic force generating element Magnetic table or the like interacts that the top of this carrier tape or profile bar clamped in the application machine is arranged in the same plane as the surface of the magnetic table, so that these two structural parts of the application machine (additionally effecting) the support plane for the substrate web or for the possibly existing conveyor belt carrying the substrate web.
- FIGS. 1 to 3. 4 to 6 show different views and variants of a construction example for one of the numerous possible or conceivable embodiments of the inventive concept.
- FIG. 1 shows a section along the line A-B of FIG. 2 through a magnetic table 5 consisting of the table top 1, the magnetic core 2 and the magnetic coil 3.
- FIG. 2 shows a detail from the longitudinal section C-D according to FIG. 1 of the same magnetic table 5, which was shown in cross section in FIG. This section shows four magnetic cores 2 together with magnetic coils 3, only half of the fourth coil being visible.
- FIG. 3 shows a schematic longitudinal section through part of an application machine that is equipped with an endless conveyor belt 4.
- this part of the application machine shown in FIG. 3 - this is a flat stencil printing machine in this exemplary embodiment - three so-called flat printing stencils 8, 9, 10 are shown.
- a magnetic table 5 of the construction according to FIG. 1 is shown, reduced in size according to the FIG. 3 scale.
- the conveyor belt 4 rests in its lower part on three support rollers 6 and in its upper part on these three prescribed magnetic tables 5 in the support areas a.
- the areas of the conveyor belt 4 designated 7 denote the locations of the deepest sag of the conveyor belt 4 in the central area. rich between the three support areas a on the three Magnetti 5's.
- the arrows 11 indicate the direction of movement of the magnetic tables 5 in the next (not shown in the drawing) work cycle of the application machine or flat screen printing machine.
- FIGS. 1, 2 and 3 analog representations, with the difference that in FIGS. 4 to 6 the subject of the invention is also shown.
- FIGS. 4 and 5 also show a cover 16 placed on or attached to the magnetic table 5.
- 4 and 6 show the invention in longitudinal view, in FIG. 5 the subject of the invention is shown three times in a T-shaped cover and in another variant without cover.
- the contact surface of the subject of the invention is arranged plane-parallel with the upper side of the magnetic table top
- the level of the contact or support surface is equal to the surface of the magnetic table cover.
- cutouts 12 are present in the magnetic table 5 between the individual magnetic cores 2, into which inserts 17 and 18 are introduced.
- a cover 16 is also provided, whereas in the case of the insert 18 its upper side lies at the level of the surface of the table top 1.
- the inserts 17, 18 themselves either represent profile strips, but can also be formed by a carrier tape.
- several variants are possible.
- the magnetic table 5 can also consist of a plurality of magnetic table elements spaced apart from one another, in which case these magnetic table elements together on a supporting beam or another Support structure, and the support band or the profile strip 17, 18 are then arranged in the spaces between the individual magnetic table elements, this support structure can also be equipped with a slide or roller guide for the support strip or the profile strips 17, 18 .
- FIG. 6 shows, and the above explanations make it clear that an application machine, in particular a flat screen printing machine built in the design constructed according to the invention, has a completely sag-free application area which extends over the entire length or over the entire slurry without any risk of sagging te of the application machine or the flat stencil printing machine.
- Application or printing machines constructed according to the invention enable the achievement of higher application quality than could be achieved according to the prior art.
- construction variants according to the invention analogous to the longitudinal movement direction shown here, are also possible for transversely moved magnetic tables. Instead of a sliding covering (cover 6), sliding rods are also conceivable.
