Definitions
- the invention relates to a method according to the preamble of claim 1 and a system according to the preamble of claim 2
- Heating in an evaporation section requires considerable structural and energy expenditure
- an artificially produced plate is wetted with an aqueous liquid and then at a high pressure of at least 70.3 kg / cm 2 and at a high temperature within the range from 204 to 288 C ° shaped
- the invention has for its object to be able to provide a chipboard or a similar board material with reduced effort with a surface pressure treatment such as embossing, without affecting the inner areas of the board in their mechanical values
- the actual plate press for the production of the plate material which will generally be a continuous double belt press, but can also be a stack press, is assigned a post-treatment section which comprises a double belt press, which can itself be the device for pressure treatment or one such a device is connected before reaching the double belt press, which is only used for aftertreatment, the plate material should be "at least partially" cooled.
- the plate material should have assumed a significantly lower temperature than the press heat, which is not exactly the ambient temperature of about 25 ° C must be, but should allow, for example, the division of the plate strand with the transverse saw, so that the aftertreatment takes place in the downstream smaller double belt press on the individual plates, which can then have a temperature, for example, in the range from 30 ° C.
- e plates should therefore be "finished", ie essentially fully developed in their mechanical properties, and the "residual temperature” that may be present should not be so high that the interior of the plates is permanently significantly deformed when the pressure is exerted Downstream double belt press only serves the purpose of effective superficial reheating of the chipboard or similar board materials Only on the
- the surface should have an influence of the subsequent pressure treatment.
- the length of the press section of the short double belt press used for reheating can be approximately two to ten meters, while the double belt presses used for the production of chipboard and similar board materials
- the heating can be operated in the double belt press to such an extent that the temperature on the surface of the chipboard to be processed is approximately 180 ° C.
- At least the devices for reheating and for carrying out a superficial pressure treatment can be set up for continuous passage of a sheet of sheet material.
- Double belt press and the embossing device should work inline. These units are separated from the double belt press for the production of the sheet material and work from a stack or a similar device for storing the cooled sheets separated from the sheet material.
- the device for exerting a superficial pressure treatment can act on the surface with a smooth counter surface and compress it only superficially, for example to increase the smoothness or the tensile strength of the surface layers.
- the device for carrying out a superficial pressure treatment is an embossing device (claim 7), which the surface of the plate material is not left flat, but gives it a desired relief, in particular a relatively shallow book depth, in the manner of a roughening
- the embossing device can in particular be a stamping calender downstream of the double belt press
- the embossing device can be provided by designing the forming belts in the double belt press itself (claim 9), for example by the forming belts bearing an embossed relief on the side facing the plate material (claim 10)
- the reheating double belt press can be arranged upstream or downstream of a device for spraying on liquid or steam according to claim 13, wherein according to claim 14 a sprayed liquid or such steam can be provided with chemical additives such as release agents, glues, plasticizers or the like to demand and improve the training of the Prague club
- chemical additives such as release agents, glues, plasticizers or the like to demand and improve the training of the Prague club
- 1 and 2 show vertical longitudinal sections through double belt presses
- FIG. 3 shows sections of the bands that can be used in the double belt press according to FIG. 2
- the illustrated exemplary embodiments deal with the surface practice of finished chipboard.
- the double belt press for the continuous production of the chipboard is not shown and is located outside the left margin of the drawing.
- the chipboard produced is cooled after leaving the double belt press, not shown, and for a while outsourced They are stored, for example, in a stack 2 or in a shelf-like storage facility. The cooling does not have to be carried out to such an extent that the temperature actually reaches the ambient temperature.
- a chipboard 1 ' is removed from the stack 2 by a device (not shown) and, as shown in FIG. 1, is inserted into a double belt press designated as a whole as 10 in the direction of arrow 3
- Double belt press 10 chipboard V located extends from the body 1 'to the point 1 "*
- the chipboard V closes at the point 1'" to a forward-running clamping plate 4 to the double band press 10 is relatively short that is, the length of the pressing section 5, in which the chipboard 1 'is pressed between heated support structures 6, 7, is approximately three meters in the exemplary embodiment.
- the support structures 6, 7 are pressed together by three force elements 8.
- the chipboard 1 ' is guided in the pressing section 5 between shaped strips 9, 11 made of sheet steel, which run endlessly over horizontal deflection drums 13, 14 and 15, 16 and over Roller chain fields, not shown, are supported on the support structures 6, 7 in a rolling manner and transmit pressure and heat to the chipboard 1 '.
- the pressure in the pressing section 5 should not lead to a thorough deformation of the chipboard 1 ', but should only be so high that a tight fit of the shaped tapes 9, 11 on the flat sides of the chipboard 1' and the corresponding heat transfer are ensured.
- the chipboard 1 'or the chipboard 4 which precedes it comes into an embossing calender 20 with cooperating rollers 17, 18, at least one of which is an embossing roller.
- the distance in the running direction 3 of the chipboard 1 ', 4 from the outlet of the double belt press 10 should be as short as possible so that the superficial reheating achieved in the double belt press 10 is not lost and the heat transferred to the surfaces has no opportunity, far into that Diffuse inside the chipboard 1 ', 4 before the embossing calender 20 attacks.
- devices 19, 21 can be provided if necessary, by means of which a liquid, for example water or steam, is blown or sprayed against the surface of the chipboard 1 ', which promotes the formation of the surface embossing May contain additives such as release agents, glues, plasticizers or the like.
- the devices 19, 21 are only optional and are therefore drawn in dashed lines. They are used when the type of Chipboard 1 ', the working speed and / or the pattern to be applied in the stamping calender 20 require it
- Sampling can be done for decorative purposes, but usually has a technical objective in the form of roughening the surface of the panel for the purpose of gluing or for the purpose of increasing tint resistance.
- OSB panels Opened Structured
- ral board with an even relief, which are used especially in the USA for roofing purposes and should prevent slipping on flat roofs when walking on the roofs
- Press section 5 not only carried out a superficial reheating of the chipboard 1 ', but at the same time the surface reef yeast 11' was imprinted
- the forming belts 9 ', 11' are additionally heated before re-entering the pressing section 5, for example with the aid of a heated roller pair 23, 24 for the upper forming belt 9 'and 25.26 for the lower forming belt 11 'it is sufficient if only the rollers 24, 25 are heated.
- the other rollers 23, 26 can be provided with a plastic coating. These rollers only have the task of promoting a heat transfer system on the rollers 24, 25. If both rolls of a pair of rolls 23, 24 or 25, 26 were heated, the relief created on the forming belts 9 ', 11' could be endangered in the long run.
- FIGS. 2 and 3 below a variant is shown in which the shaped strips 9 ', 11' do not themselves carry a relief, but are smooth and the relief is formed by moving grating strips 12, which are likewise formed by additional heating rollers 22 can be heated.
- the actual forming tapes correspond to the forming tapes 9, 11 in FIG. 1.
