Definitions

  • the invention relates to a method and an apparatus for the production of paper webs to be longitudinally divided into several strips for gluing the edges of boards made of wood, in particular furniture, in which an optionally colored paper web is printed with a wood color and wood structure, impregnated with an aminoplast, in particular melamine resin, lacquered and is shaped. Then the track is divided lengthways.
  • the known method is carried out in such a way that the optionally colored paper web on a roll is unwound and printed and rewound in a printing machine, which usually consists of several printing units, with the wood color and the wood structure pattern.
  • a printing machine usually consists of several printing units, with the wood color and the wood structure pattern.
  • the impregnation of the paper webs with melamine resin, the painting and the embossing are separate work processes for the implementation of which the web is in turn wound up and unwound.
  • the narrow strips are then produced by slitting the webs lengthways.
  • This method is obviously uneconomical due to the numerous handling processes and it would be desirable if all processing processes could be carried out in one pass.
  • the throughput speed in all processing operations would have to depend on the throughput speed of the processing operation that requires the lowest throughput speed, and in this case this is the impregnation of the webs with melamine resin.
  • throughput speeds of 20 to a maximum of 40 meters per minute can be used, while printing, on the other hand, speeds of 80 to 200 meters per minute. Under these circumstances, performing all machining operations in one pass would result in an even less economical result.
  • the object of the invention is to be able to produce the paper webs which are then to be cut only by slitting into narrow strips from a preliminary product in only one pass, even in small quantities.
  • the invention relates to a method for producing paper webs to be longitudinally divided into several strips for gluing the edges of boards made from wood, in particular furniture, in which an optionally colored paper web is printed with a wood color and a wood structure, impregnated with an aminoplast, in particular melamine resin , lacquered and embossed and which is characterized in that the paper used is first impregnated under stiffening and then has a weight per unit area of about 250 g / m 2 , whereby a preliminary product is obtained, which is processed in a further operation to the finished paper web is printed by using the indirect gravure printing process, then varnished and finally embossed.
  • the throughput speed in the method according to the invention is high, since it is no longer limited by the low throughput speed required for soaking with melamine resin. Since the end product can be produced quickly and economically in almost any small batch sizes, storage of the end product can be almost completely eliminated and storage can be limited to the preliminary product.
  • the paper web is several successive Subjected to printing and dried by warm air after each printing. This enables a high throughput speed and at the same time a small overall length of the device used to carry out the method.
  • the paper web can be subjected to several successive painting processes and the paint is cured by infrared rays after each painting process, the heat applied to the paper web increasing with increasing distance from the point at which the paint is applied.
  • the paint is cured quickly and gently, damage to the paper is avoided, and high throughput speeds and a short overall length of the device are made possible.
  • Another object of the invention is a device used to carry out the method characterized above, which in turn is characterized by an unwinder, one or more indirect gravure printing units, one or more coating units, an embossing unit and a winding device.
  • the device according to the invention allows the primary product printed with a base color and soaked in melamine resin to be processed in one pass to the finished paper web, which then only has to be divided lengthways.
  • the unwinding device is followed by a clamping device for the paper web.
  • This clamping device serves to hold the end of the previous paper web when changing the roll so that it can be glued to the beginning of the following paper web, so that the device is traversed by an endless paper web.
  • a brushing device provided with rotating brushes in front of the first printing unit, by means of which dust that may be on the surfaces of the paper web is removed and thus a clean print is ensured.
  • a Shore hardness A of about 50 is expediently chosen for the rubber coating of the transfer roller and a Shore hardness A of about 85 for the rubber coating of the backing roller.
  • doctor blade in the printing units in such a way that they can be pivoted about their longitudinal axes by more than 90 °. This facilitates the often required removal of the ink roller.
  • the inking units of the printing units can have ink troughs that are provided with an ink supply connected to an ink pump and a color return that determines a level. As a result, the color level in the color troughs is kept constant in a very simple manner.
  • the coating units are expediently designed such that they have coating pick-up rollers arranged in coating trays, which are provided with a rough, in particular rastered surface and which interact with coating transfer rollers arranged above them, while counter-pressure rollers are arranged above the coating transfer rollers and above the paper web. This results in an extremely uniform application of lacquer to the paper, the thickness of which can be influenced by the surface shape of the lacquer pick-up roller.
  • the paint troughs arranged in the coating units have paint inlets arranged at a level-determining height, which are connected via lacquer feed lines provided with shut-off devices to airtightly closable paint containers arranged above the paint troughs.
  • the paint level in the paint troughs can be determined in the simplest way and the contact of the paint with the air is limited to a minimum.
  • the embossing unit has an engraved embossing roller and a counterpressure roller which is made of non-resilient material and has a flat surface.
  • a cylinder is used, which consists of a multiplicity of pressed paper disks which, however, wears out very quickly and also gives an imprecise embossed image.
  • the unwinding device shown in FIG. 1 and designated in its entirety by 1 consists of a base frame 2 on which two levers 3 of equal arm running parallel to one another are arranged so as to be pivotable about a pivot point 4.
  • the levers 3 have tensioning devices 5, 6 at their ends for receiving paper rolls 7.
  • the paper is paper soaked with an aminoplast, in particular with melamine resin and possibly colored. The coloring of the paper is necessary if the paper is printed with a relatively dark wood color. Otherwise the cut edges of the paper would appear light colored.
  • the tensioning device 6 picks up a further paper roll, the beginning of which is laid ready and connected at the appropriate time to the end of the paper web of the roll 7. This requires a brief interruption in the unwinding process.
  • the roller on the tensioning device 6 then takes the place of the previous roller 7.
  • the tensioning devices 5 and 6 are actuated pneumatically, which cannot be seen in the drawing.
  • Magnetic powder brakes also not shown in the drawing, which are controlled by the scanned diameter of the paper roll, ensure a constant tension of the paper webs.
  • devices for the lateral positioning of the paper webs are also not shown in the drawing.
  • the first printing unit shown in FIG. 2, designated in its entirety by 8, has on its paper inlet side first behind guide rollers 9 a fixed clamping bar 11 arranged below the paper web 10, which is opposite a movable clamping bar 12 above the paper web 10, which with the help of one or more Compressed air cylinder 13 can be pressed against the fixed clamping bar 11, whereby the paper web 10 is held.
  • a fixed clamping bar 11 arranged below the paper web 10
  • a movable clamping bar 12 above the paper web 10 which with the help of one or more Compressed air cylinder 13 can be pressed against the fixed clamping bar 11, whereby the paper web 10 is held.
  • the clamping device 11, 12, 13 is followed in the running direction of the paper web 10 by a pair of rotating brushes 14 and 15, between which the paper web 10 runs and which can be pressed against one another by a pneumatic adjusting device 16.
  • the brushes are used to remove dust and foreign bodies from the surfaces of the paper web, as these can impair the printed image and lead to malfunctions.
  • a suction device not shown in the drawing, for the resulting dust is arranged.
  • the actual printing unit consists of the gravure engraving roller 17, the transfer roller 18 arranged above it and the counter-pressure roller or impression roller 19 arranged above it.
  • the transfer roller 18 and the counter-pressure roller 19 have rubber coatings.
  • the rubber coating of the transfer roller has a Shore hardness A of approximately 50
  • the rubber coating of the counterpressure roller has a Shore hardness A of approximately 85.
  • the ink fountain designated 20 can be lowered from its operating position shown in the drawing and the one not shown in the drawing with the gravure engraving roller 17 cooperating doctor blade is pivotable from its operating position about its longitudinal axis, which runs parallel to the roller 17, by at least 90 °. In this way, the roller 17 can be easily and freely removed for the purpose of changing.
  • the gravure engraving roller 17 picks up ink from the ink trough 20 in its depressions, the excess located on the roller is stripped off by the doctor blade, not shown in the drawing.
  • the ink located in its depressions gives off the roller 17 to the rubber coating of the transfer roller 18 and from there the ink reaches the underside of the paper web 10, which is pressed against the transfer roller 18 by the counter-pressure roller 19.
  • an excellent wood structure print can be produced on the paper web 10, which is stiff due to the melamine resin impregnation and otherwise difficult to print on.
  • the still wet paper web 10 is deflected around two further guide and deflecting rollers 21, 22 and reaches an air box 23 in which the ink is dried by blowing with warm air.
  • the ink supply to the ink pan 20 is shown in detail.
  • 24 denotes an approximately bucket-shaped paint reservoir into which an immersion pump 25 is inserted.
  • the submersible pump 25 feeds paint into the paint pan 20 via a line 26.
  • a return line 27 is also arranged on the paint pan 20, through which excess paint runs back into the paint container 24.
  • the point of confluence of the return line 27 into the paint pan 20 determines the color level prevailing in the paint pan.
  • At the bottom of the ink pan 20 there is a further return line 28 which opens into the first return line 27, but which can be shut off by a valve 29.
  • This second return line 28 serves to completely empty the ink pan 20 when the valve 29 is opened.
  • the delivery rate of the submersible pump 25 is adjusted so that more ink is always delivered than is consumed, so that a constant backflow through the backflow line 27 takes place.
  • the second printing unit shown in FIG. 3, designated in its entirety by 30, is basically of the same construction as the printing unit 8 and therefore need not be described in more detail. However, he lacks the clamping device 10, 11, 12, 13 and the rotating brushes 14, 15 with adjusting device 16. As a rule, three or more printing units of the type described above will be located in a device according to the invention. In the first of the printing units mentioned above, an engraving roller which has a wooden structure will generally not be present, since there the paper is printed all over with a wooden color or basic color.
  • the coating unit shown in FIG. 4 is designated in its entirety by 31.
  • the coating unit 31 has a coating pan 32 into which a coating roller 33 is immersed.
  • the lacquer roller 33 has a rough, preferably engraved or rastered surface, the roughness of which is dimensioned such that it takes the desired quantity of lacquer from the lacquer pan 32.
  • the paint is delivered from the coating roller 33 to a transfer roller 34 and from this to the underside of the paper web 10.
  • a counter pressure roller 35 presses the paper web 10 against the transfer roller 34.
  • the rollers 34 and 35 are covered with rubber and correspond to the rollers 18 and 19 of the printing units.
  • a water-dilutable acid-curing lacquer is used.
  • Infrared heaters are used to dry the paint. These radiators, denoted individually by 39, are combined to radiator sets 36, 37, 38.
  • the emitter set 36 which is first reached by the lacquered paper web 10, contains relatively few emitters 39, so that the heat applied to the paper web is comparatively low.
  • more heaters 39 are arranged, so that the heat load on the paper web is greater in these areas.
  • the thermal load on the paper web can also be influenced by its distance from the paper web. The emitters emit a short-wave infrared light.
  • the paint supply to the paint tray 32 is shown in detail in Figure 8.
  • a paint reservoir is designated, which can be closed airtight with the help of a lid 41.
  • a line 42 leads from the lacquer storage vessel 40 to the lacquer pan 32.
  • the line 42 can be shut off with a shut-off valve 43.
  • the shutoff valve 43 is closed and the paint reservoir 40 is filled.
  • the shut-off valve 43 is opened and so much lacquer closes in the lacquer pan 32 until the lacquer level 45 has reached the upper edge 44 of the junction of the line 42 into the lacquer pan 32. If paint is removed from the paint tub 32 by the roller 33, a corresponding amount of paint flows into the tub 32 through the line 42.
  • this arrangement has the advantage that the paint comes into contact with air as little as possible.
  • the method is carried out in such a way that, using the first coating unit, only a relatively thin layer of lacquer is first applied to the paper web 10 and cured thereon. This thin layer of lacquer closes the surface pores of the paper.
  • a thicker layer of lacquer is applied to the paper web treated in this way, which, however, cannot now penetrate the paper, but is cured on the first lacquer layer.
  • the stamping unit 46 shown in FIG. 5 is designated 46 in its entirety. It contains an engraved embossing roller 47 made of steel and a counter-pressure roller 48 also made of steel with a smooth surface.
  • the rolls are pressed against each other by a pneumatic cylinder 50 and the height of the roll gap remaining between them is set by a stop 49.
  • the paper In the roll gap passing through the paper web 10, the paper is compressed at those points at which the engraved embossing roller has 47 elevations.
  • two rubber-coated rollers 51 and 52 are provided, which can also be pressed against one another by a pneumatic cylinder 53. These rollers serve to pull the paper web 10 through the device when the rollers 47 and 48 have moved so far apart that they do not grip the paper web. In this case, the rollers 51 and 52 are driven. In embossing operation, the rollers 51 and 52 are without drive and the rollers 47 and 48 are driven.
  • the winding station shown in FIG. 6, designated 51 in its entirety, corresponds essentially to the unwinding device 1 shown in FIG. 1, but with the difference that its tensioning devices 53 and 54 are driven to wind the paper web 10.
