Description

The The present invention relates to a coating apparatus for Task of at least one covering material on the top of a carrier material for one Plant for the top and bottom coating of web-like carrier materials with cover masses, like bitumen, in which at least one scoop roller of at least one Pan during the passage of the carrier material at least a first cover mass from below to the carrier material anträgt, and at the same time with two calibration rollers that below and above with Deckmassen covered substrate brings to a defined product thickness.

Web-shaped, coated material is required in various technical fields. For example, describes the JP 09 099 264 A the order of separate media between partitions on top of a web. The DE 1 925 467 U1 describes a casting machine for adhesives with adjustable trained side walls. The use of partitions in coating apparatus is further from the JP 55 116 464 A known. Finally, the reveals DE 697 06 728 T2 a device and a method for applying liquid resin to a moving web, wherein a metering roller is provided at the end of a feed.

Great demand on a web For example, coated material is included. with bituminous mass coated roofing membranes, here used more and more webs which will allow easy laying by that one before Laying activated adhesive layer facilitates the bonding process. In these roofing membranes is also on the upper deck mass layer a layer with a litter material, such as slate granules, arranged, which is to protect the cover bitumen in sunlight, as the plastic carrier and the masses are not UV stable are. In addition to roofing membranes, there are a number of other applications of coated material; esp. Coated mineral and glass wool plates to isolate on the construction; in the vehicle for anti-drone and Vibration Isolation the body; Carpet coatings; etc.

at the production of such webs, it is known, a carrier material in raw or previously impregnated, d. H. with impregnating liquid like low-viscosity bitumen soaked, Condition horizontal - or possibly also vertical - too coat.

Originally was about applicator rolls at the same time from the bottom and top one and the same bitumen blanket - in order Coating also the margins - in excess to the carrier offered as well as over stripped two calibration rollers and brought to the desired product thickness.

Later are Also known devices in which the bitumen mass from above via appropriate Distributor in excess fed and on top of the substrate be abandoned. The surplus runs in a, preferably heated, pan and at substantially horizontal Passage of the carrier material carries a scoop roller the same bitumen from below to the carrier.

Classic built coating systems have in particular to the detriment, that on the top and bottom of the carrier always only bitumen of the same Kind and goodness could be applied - already the top and bottom coat with different on bitumen based material was not possible with classical devices, a fortiori no multiple coating.

This, ie the production of single or multiple under- and / or top coated web-like carrier materials or carrierless webs with or from one or more coverings, such as bitumen, possibly with the application of a scattering material, such as shale granules, quartz sand, talc, etc. , and optional cover with films or the like was first by the in the EP 0 423 774 B1 disclosed coating system allows. This comprises at least one cooling belt and at least one separate coating device for the lower and upper sides of the carrier. The single or multiple coating with different toppings is therefore based on the idea of separation of top and bottom coating, which not only the acquisition of a coating system and thus the possibly premature scrapping of the old plant to the detriment, but due to the much larger footprint higher operating costs had the consequence. However, for the first time ever multiple and / or differently coated tracks were manufacturable.

Of these, The present invention is based on the object, to provide a coating device, with the planned one Upper and lower coating of different masses on a support is possible. In particular, existing systems should be of the classical type upgradeable be.

These The object is achieved by a coating device according to the features of the independent Patent claim 1 solved. Advantageous training and further education, which individually or in combination can be used together are the subject of the dependent Claims.

The coating device according to the invention is based on known coating devices for the task of at least one covering composition on the upper side of a carrier material, characterized in that the coating device for at least partially abandoning at least one covering compound different from the first covering composition on the upper side of the carrier material comprises at least one rear wall, at least one first side wall, at least one first partition and at least one front wall, wherein the front wall is at least is formed in sections by the upper Kalibrierwalze.

Preferably the coating device comprises a further, second side wall, which advantageous bitumen excess, which otherwise laterally over the train would run out confines.

Around To be able to form webs of different width, the side walls are preferred adjustable trained.

to Delimitation of different cover masses or top coating different width of side by side coating compositions, z. B. bitumen plastic modified, bitumen self-adhesive, etc., it is proposed between first partition and first or second Side wall to arrange at least one other partition.

As well like the side walls can also the partitions adjustable to the formation of different width partial webs and / or be used variably inserted between the side walls.

to improved processability of the covering composition (s) is preferably the Rear wall, optionally also the side and / or the partitions, the coating device heated formed.

alternative or - to further improved processability of the cover mass (s) - cumulative For this purpose, it is proposed the back wall with silicone, with teflon and / or another non-stick properties coated material to coat.

Around while the coating of adjacent sub-webs to minimize mixing, have at least the partitions and possibly the side walls to upper calibration to a corresponding to the radius of the roller Contour on.

For the purpose of Training best possible Impacts of neighboring Part-tracks have the partitions in extension to the upper Kalibrierwalze towards at least the end a decreasing wall thickness on.

According to the invention preferred is as possible for training good sliding properties of the cover mass / s the coating device in the direction of passage of the carrier material sloping tapered formed.

In this regard has in particular one in the direction of passage of the carrier material sloping inclined rear wall proven.

alternative or cumulatively, for the purpose of preserving it has improved rejuvenation a back wall proven, which bent at least adjacent to the carrier material in the direction of passage is trained. Leave a radially bent end having back walls also advantageous with a larger angle of inclination α to the substrate Arrange.

According to the invention preferred is one possible steep inclination angle α between Back wall and support material to strive; depending on available Space is the inclination of α at least 15 °, preferably between 25 ° or 30 ° and 45 °, if necessary even 60 °.

Furthermore have rejuvenated proven sloping coating devices, at which not only the - if necessary a round bent end having - rear wall in the pulling direction of the carrier material sloping inclined, but also that of the upper Calibration roll not formed portion of the front wall in the pulling direction of the carrier material sloping inclined, wherein the inclination angle β of the front wall preferably steeper than the angle of inclination α of the rear wall is to be selected, preferably by more as at least 5 °.

According to the invention preferred finally shows a left between the upper calibration and back wall surface for deck mass / n on the top of the substrate one in the direction of passage of the carrier material smaller extent than the radius of the upper Kalibrierwalze, whereby while the coating advantageous voltages are taken from the substrate.

The present invention is suitable for new, but especially for already Existing installations for the top and bottom coating of web-like carrier materials with toppings, such as bitumen, at least one scoop roller from at least one ladle when passing through the carrier material at least one first cover compound from below applied to the carrier material, and at the same time two calibration rollers with - now arbitrarily different - cover masses scheduled coverable support material brings to a defined product thickness.
