Definitions

• the invention relates to a device on machines for printing, coating, dyeing or the like. of sheet-like material using at least two working parts which exert pressure against one another or onto the material web to be processed, one of these working parts, namely the processing base, being equipped with magnets which are inserted into the surface serving as printing or processing base and this area is covered with a cover.
• the groove should be changeable in its width and depth and should be adaptable to the respective machining requirements. But this is impossible, because the width and depth of such a groove can no longer be changed in an existing machine.
• cover plates are required. The thinner the cover plates, the greater the risk that the cover plates will dent. Who will cause new processing errors; the stronger the cover plates, the more the magnetic contact pressure is weakened, which in turn can lead to malfunction.
• the subject matter of the invention presented herewith is a new type of surface covering with which an elastic underlay is achieved which does not suffer any permanent deformation after a long period of operation and which can be implemented in any thickness and with different groove widths and shapes.
• the cover is a plate made of non-magnetizable material with a groove on the side facing the magnetic bar, which extends approximately over the region 25 of the magnetic poles.
• This new type of cover plate is flat and smooth and the rounded groove, which is open towards the bottom or towards the inside, looks like a vaulted structure in the load situation arising from the machining process, 30 seen in cross section.
• This new form of construction 'of the cover plate three remarkable advantages: optimal variability of the load options with regard to different roller diameters and contact pressures, optimal elasticity effect in that the elasticity extends to the entire range of all occurring load cases and moves in a very small range, which only comprises a few tenths of a millimeter.
• Another advantage is that the covers can be made from material qualities that do not tend to bend or buckle
• FIGS. 1-3 The same partial cross-section of the device is shown in FIGS. 1-3.
• 1 shows a section of the working part designed as a machining plane, in which the magnetic cores designated with 2 are inserted. On the the pole ends of the
• FIG. 1 Magnetic cores facing the inside of the cover plate 3 is shown with the present invention 4 'attached recess (groove) which inFig. 1 is rounded, rectangular in FIG. 2 and polygonal in FIG. 3.
• the sheet-like material web to be processed is denoted by 5 and the second working part, which is designed as a magnetically attracted roll, is denoted by 6.
• a doctor blade can also be used.
• the width of the recesses 4 is shown to be somewhat narrower than the magnetic core diameter but also possible in the same or larger width than the magnetic core diameter.
• the cover plates 3 are fastened on the part 1 so that they cannot move in the machining direction, which is not shown in the drawings.
• the flat or round stencils that may be required for printing on the material are also not shown in FIGS. 1-3, which are limited only to the presentation of the essential facts of the invention.
• Molybdenum bisulfide (Molykotte) mixed high-molecular low-pressure polyethylene is particularly proven.
