Definitions
- the present invention relates to a method and apparatus, in continuous production, for supporting details on large forming surfaces and at high surface pressure.
- the CH-PS 639 319 teaches a method and apparatus for ac- celerating curing of the adhesive in the production of la ⁇ minates with intermediate layers of carton and outer surfaces of plasterboard. Curing takes place by moving the laminate past a radiation source, and the laminate is kept together, while being conveyed past the radiation source, with the aid of air cushions pressing against it on either side of the horizontally conveyed laminate. To avoiding bucking in the intermediate layer of the laminate, the pressure in the air cushions is regulated to a relatively low value, and there - is achieved no pressing force of the same magnitude as with 2 pressure rolls or forming belts in this known method.
- the chief object of the present invention is to provide a method and apparatus of the kind mentioned in the introduc ⁇ tion, with which the problems described in connection with 5 known processes have been eliminated, and very large sliding forming surfaces are achieved with a minimum of friction and insignificant deflection of the forming surface.
- Another object is to achieve a method and apparatus par ⁇ ticularly suitable for use in continuous production of so- 10 called sandwich structural elements.
- Fig. 1 is a perspective view of the upper part of a 20 plant for vertically manufacturing so-called sandwich struc ⁇ tural elements
- Fig. 2 illustrates the continuation of the lower part of the plant in Fig. 1, more specifically showing the right hand part of the plant, which is symmetrical about the illustrated 25 centre line, this lower part being implemented in accordance with the invention
- Fig. 3 illustrates to a larger scale a detail of the pressing plane in the plant of Fig. 2.
- the plant which is illustrated in Fig. 1, is intended for - 51 -' vertically manufacturing so-called sandwich structural elements.
- the method of manufacturing these elements and the illustrated plant for carrying out the method are described in detail in the Swedish patent application 86001441-2.
- the process proceeds such that a core material, e.g. cellular - > - > plastics, is supplied in pieces or panels 10 of the desired size to an input station.
- the panels 10 which can have a width of up to 3-4 meters are supplied to the input station by such as a mechanical direction-changing and collecting means 12.
- the input station comprises gripping belts 14, which are caused with the aid of platens 16 to excercise a pressure against the panels 10 sufficient for the belts to grip the panels and advance them to the forming station of the plant.
- a pressurised medium can be conventionally blown in between the belts 14 and platens 16 to facilitate movement of the belts over the platens.
- the core material meets the cover- ing layers or skins 18, e.g. glass fibre reinforced plastics, sheet metal etc.
- the skins 18 are taken over pressure rolls 27, which lead the skins 18 downwards while pressing them against the core material.
- the skins 18 are coated with adhesive on their sides coming into contact with the panels, and this ad ⁇ hesive forms a pool 24 immediately before the nip between panels 10 and skins 18, as is described in more detail in the mentioned patent application.
- the skins 18 are pressed against the panels 10 while the adhesive cures, the latter forming, as mentioned, an adhesive pool 24 (see Fig. 2) in front of the nip between panel 10 and skin 18 on either side of the panel.
- a pressing force of between 10 and 1000 kPa.
- this is arranged for by the sandwich ele ⁇ ment formed from the panel 10 and skins 18 being caused to pass over a forming table 52, which has holes or perforations 54 (see Fig. 3) for the passage of air, thus permitting air pressure to act on the skins 18.
- the air pressure is regulated such as to provide a desired pressing force, e.g. a pressing force of 10 kPa at 0,1 effective atmosphere.
- the air film be ⁇ tween the skins 18 and the surface of the forming table 52 has a thickness of up to 0,5 mm and allows the sandwich element which is produced to' pass frictionless over the surface of the forming table 52.
- the air access perforations 54 in the surface of the table are adapted in size and number so that lateral ' air leakage from the gap between the produced sandwich element and table 52 corresponds to the air passing through the table, without there being any pressure drop therein.
- the air pressure is created in an air pressure chamber 56 situa- ted against the table 52, and in accordance with the inven ⁇ tion this overpressure is taken up by a bolster slab 58, which can be allowed an optional bending deflection without the production of sandwich elements being affected, the press ⁇ ing surface remaining quite fait.
- the air which is supplied to the gap between the sandwich element and forming table 52 may be given a temperature adaplted for curing the adhesive joining the core material 10 and skins 18, and for this pur ⁇ pose the pressure chamber 56 may be subdivided into a plural ⁇ ity of separately regulatable heat zones.
- the skins 18 can alternately be made up from webs 28 of glass fibre fabric which are reeled off from two storage rolls 26, the webs 28 coming into mutual contact as they pass round an idler roll 30. At this roll they also meet up with a thin sheet, e.g. a foil or film 32, which is reeled off from a storage roll 34.
- the sheet 32 is caused, with the aid of a cambered idler roll 36, to pass over the upper side of a hori ⁇ zontal table 20 and before meeting with the web 28 the foil 32 is on its upper side given a coating of gel sprayed on to the sheet by unillustrated nozzles to form a gel pool 40 in front of a doctor blade 42.
- the table 20 is heated and can be subdivided into separately regulatable heat zones for regulating heat supply to the coatings of gel and adhesive.
- the table 20 is suitably similarly provided with means for the passage of air to facilitate the movement of the sheet 32 and the web 28 over its surface.
- the glass fibre coated skin 18 is carried over a pressure roll 22 arranged at the left side of the table to the vertical path and at the same time the skin is brought into contact with the core panel 10 by the pressure roll 22.
- the sandwich element thus formed passes over the forming table 52 as described, whereby the element is formed by the sheet 32 the air pres- sure now acting against the sheet 32, as described earlier.
- the sheet 32 can either be smooth or patterned depending on what surface is desired on the final product.
- the sheet 32 After passage over the forming table 52 the sheet 32, which has now fulfilled its purpose, is pulled off with the aid of a support roll 60 and a cambered roll 62, and reeled onto a receiving roll 64, while the sandwich element compris ⁇ ing panel 10 and skin or skins 18 continues vertically down ⁇ wards for further processing.
