SPECIFICATION
An installation and method for the coating and preparation of flat material webs
The invention relates to an installation for the coating and preparation of flat material webs as well asa method for the coating and preparation offlat material webs using this installation.
With known installations thermoplastic powder is transferred by means of an engraving roller onto the flat material webs. In the engraving roller recesses are arranged uniformly over the periphery, which recesses serve for receiving the deposit material provided for the transferring to the material web.
With the use of at least one heated pressing-on roller the thermoplastic powder is transferred to the flat material web at a high temperature of about 200 300"C, with linear pressure between the engraving roller and the pressing-on roller. By this means the powder transfer is limited to the short linear contact in the gap between the pressing-on roller and the engraving roller. The powder, after the transferring, is slightly baked together on the flat material web and is sintered by further temperature action.
These installations are suitable exclusively for one-sided coating of flat material webs with thermoplastic powder (powder point method), whereby the material webs must be correspondingly temperature resistant. Thereby however, from the outset the range of application is substantially limited. A flat material web must not exceed a certain volume as otherwise the powder transferring temperature is not sufficient and therefore a faulty, or no, coating results. Alternatively the material web can burn or, in the case of synthetic webs, harden and are thus unusable. The trickle capacity of the powder must be given as otherwise due to the small powder entry zone in the powderfunnel a regularfilling of the engraving recesses is not possible.The granulation of the powder must be such that the particles are substantially round. The sizes of particles play a decisive role and must not exceed 250 microns, otherwise regular coating is not achieved. By means ofthe so-called powder point method in particular textile webs are coated whereby the coated textile material is used essentially in the clothing industry, particularly for ready made clothing, for example for shirt-collars, linings in suits etc.
The engraving roller is extremely sensitive; the manufacture of the engraving of the roller is costly.
At the already mentioned high temperatures of about 200-300"C it cannot be excluded that the thermoplastic powder to be applied will melt and set in the engravings of the roller. Thereby however the function of the engraving roller is substantially adversely affected.
The present invention is based on the problem of providing an installation and a method with which, with the omission of the heated rollers as well as the engraving roller, a substantial increase of the pow dertransferring surface is obtainable. Furthermore, the field of use is extended to the most varied flat material webs which can be coated on one as well as on two sides with the most varied materials.
According to the invention there is provided an installation for coating and preparation of flat material webs with at least one endlessly rotating material transfer apparatus disposed under a feeding container, the outer face of which transfer apparatus is provided engravings in which the depositing material, provided for the transfer to the material web, is deposited, and the material web is guided past the transfer apparatus over at least one guide device for the purpose of transferring of the deposit material thereto, characterised in that said material transferring apparatus comprises a first endless rotating band at least one run of which is overlapped by a second parallel endless band.
With the installation according to the invention wet-coatings as well as dry-coatings can be carried out with the most varied depositing materials on different types of flat material webs. Particularly advantageous is the simultaneously possible twosided coating of the material web whereby due to the installation and method according to the invention, it is possible without special provisions to deposit onto individual sides of the material web different deposit materials. Due to the obtained flat contact zone between the material deposit endless bands and the contacting endless bands with the material web to be coated lying thereon, the deposit material is transferred by flat contact pressure and therefore at the same time a variable heat treatment of the material web is carried out.
One embodiment of the invention is shown in the accompanying drawing and is described in more detail below.
Underthe feed container 11 for the material to be fed is disposed an endless band 1 the upper face of which has engravings formed in any desired way, for example recesses in the form of grooves. This endless band serves forth transferring of the deposit material onto the flat material web 4. It is an advantage of the installation according to the invention that the size of the transferring section is variable whereby instead of the hitherto known linear pressure for the transferring of the deposit material, a surface-contacting pressure occurs. For this the upper and lower runs 1' and 1" respectively of the endless band 1 are overlapped at one end by parallel and contra-running endless bands 2 and 3, whereby the length of the overlapping amounts to at least one third of the length of the endless band 1.
The overlapping length is at the same time the length of the transferring section.
The material web 4 lies freely on the endless band 2 and is coated whilst being guided in the region between the lower run of the endless belt 2 and the upper strand 1 ' of the endless belt 1. In this overlapping section the deposit material is transferred from the endless band 1 to the flat material band 4. This transferring section is compared with the extent of the prior art method described, increased by up to 400 times. For the coating on both sides of the material web 4 with the construction of the present invention, the endless band 3 is arranged under the lower stand 1 " of the endless band 1, which for the transferring of the coating material is likewise provided with engravings formed in any desired manner.The endless band 3 therefore can serve in one case only as a pressing on or counter pressure band to the endless band 1 and such case is formed flat surfaced, whilst in an alternative case the band 3 can serve as a transferring band with engravings located on its outer surface. With twosided coating of the material web 4, the appropriate engraved endless band 3 is provided together with the necessary deposit material supply. For this there is associated with the endless band 3 a feedcontainer 5' which is connected via a conveyor worm 6 to a supply container 5.
All endless bands 1, 2 and 3, may be of plastics material, for example, Teflon or polypropylene; of metal, for example, aluminium, copper or steel laminate, silicone finished metal laminate; or of textile material. The endless bands 2 and 3 arranged respectively above and below the endless band 1 serve exclusively as material transferring apparatus and are arranged to be adjustable in height whereby the distance from the respective upper strand or lower strand 1' and 1" can be varied. The endless bands 1 and 3 are finished in an anti-adhering manner as material transferring bands.
Instead of the already mentioned feed container 11 associated with the endless band 1 there may be arranged a wide slit nozzle 12 of an extruder.
Between the feed containers 11 and 5', or the wide slit nozzle 12, and the respective associated endless bands 1 and 2 is formed a flat depositing zone 9 and 10.
For ensuring a uniform transfer-height of the transfer material onto the engraved bands 1 and 3 there are associated with the respective feed container 11 and 5' orthe wide slit nozzle 12, exchangeable doctor blade systems 14. Hereby there may be arranged, at a variable angle, anti-statically finished, plastic doctor blades 14, for powder of any grain spectrum. For pasty masses of any viscosity rubber doctor blades 14 of differing degrees of hardness may be provided, and for non-trickle masses doctor blade rollers in combination with the anti-statically finished plastic doctor blades 14 are provided.
Advantageously there are provided within the endless bands 1,2 and 3 any desired form of heating apparatus 13 for the heating of the material web 4 and for obtaining a fusing effect. Above the endless band 2 there is provided an infra-red chamber 7 for heating the material web 4. With such heating, care is to be taken that the melting range of the deposit materials is not exceeded. The complicated and difficult temperature conduction with the known installations using pressing on and engraving rollers is avoided in the present installation by means of the flattransferring section comprising a lengthy contacting zone between the endless bands 1 and 3 and the material web 4 to be coated.The transfer of material in the present installation takes place so that, according to the circumstances, the necessary correct ratios can be adjusted easily via the suitable heat treatment, which is not possible with the linear contact of the prior art rollers. With the known roller arrangement a kind of heat shock takes place in the linear contact zone, which necessitates an accurate and accordingly expensive temperature regulation and control.
For the treatment of the material web 4 there may be disposed in the endless bands 2 and 3 cooling apparatus (not shown). Forthe further thermal treatment of the material web 4, already coated on one or both sides, an infra-red chamber 8 is provided in which the applied deposit material is melted and intimately connected to the material web 4. Alternatively, however, in the infra-red chamber 8 only a drying and a stabilising of the deposit material may take place It is also possible to carry out this drying and stabilising by means of other suitable heating apparatus. In a connecting pair of calenders 15 the coated web 4 is cooled and calendered. The material webs 4 may have differring volumes and consist of paper, textiles, plastic foils of any melting range, metal or metallised plastic foils or sheet metal of any composition of up to 1 mm thickness.On the material webs 4, consisting of the most varied materials, there can be deposited without difficulty due to the form of the installation according to the invention duroplastics material modified on one or both sides and thermoplastics material in powder form, duro or thermoplastic base materials and dispersions, and finest point or structure preparations for the stabilising and preparation. It is also possible without trouble to coat the material web 4 on both sides and to apply to the individual faces thereof different deposit material, for example on one side of the material web powder and on the other side pasty material. Whilst with the known installations only a powder point coating is possible, with the invention a versatile possibility of use is opened up.
The machine may be driven continuously, discontinuously or step-by-step with the carrying out of the differentforms of the method. Furthermore, the endless band (1) may be of a length such that it is usabie as a drying station for use in the applying of pasty masses of dispersions. Likewise the length of the endless band (1) may advantageously be chosen so as to provide a plasticising section for deposited thermoplastic or duroplastic powder and paste. The materials may be applied by scattering from a rotating sieve under pressure by a spreading method by a spraying method or by means of a stamped roller or an extruder onto the endless band.
The installation according to the invention affords a heating of the material web 4. The material web is thus, during the transport through the coating system, left substantially at room temperature. High rates of change of temperature during the coating procedure do not occur in the method according to the invention, so that damage or weakening of the material band in consequence of excessive temperature is avoided. By means of a distance between the depositing zone 9, 10 and the endless band 2,3 guiding and pressing the material web, selected corresponding to the behaviour of the materials to be applied, for example, hot and/or shapelessly applied materials can be cooled or plasticised up to a temperature so that a transferring to the material web 4 is still ensured. In order to ensure the transferring to the material band 4 advantageously the overlapping region of the bands 2, 3 can be designed larger corresponding to the behaviour of the materials. The materials to be applied, such as for example thermoplastic powders or paste, are so dried and/or plasticised that they are transferable.
The temperature ranges may hereby be between 50 and 150"C.
