Definitions
- the present invention relates to a corrugated cardboard manufacturing machine featuring a new type of cardboard supporting/conveying belt, which has never been used before for this purpose and has proved surprisingly advantageous as compared with traditionally used belts.
- corrugated cardboard of the type normally used for boxes or miscellaneous packaging, is produced on special corrugating machines*, the sheets of cardboard are fed to the corrugating machine packed tightly between respective cylinder-operated supporting/conveying belts, and are subjected to the combined action of heating assemblies and pressure plates for gluing and shaping the various layers forming the corrugated cardboard.
- the belts supporting and conveying the cardboard sheets are made of felt, in particular acicular felt, or conventional fabric, which involves various drawbacks.
- felt or conventional fabrics mainly on account of not always being of even thickness, fail to provide for thin, top-quality finished products, and are therefore unsuitable for producing boxes or packages for select items such as perfume, ornaments, etc., unless the output speed of the machine is greatly reduced.
- felt or conventional fabrics which must be joined when fitted to the corrugating machine, show marked breaks in continuity at the joints, which further impair the quality of the finished product .
- Felt or conventional fabrics are also relatively heavy and therefore difficult to assemble onto the machine; the weight, combined with a high friction coefficient, of such materials increases the energy consumption of the machine; and, finally, not being very permeable, felt or conventional fabrics not only impair dispersion of the steam issuing from the cardboard, but also call for coating the cardboard with a relatively large amount of glue .
- a corrugated cardboard manufacturing machine of the type comprising at least one continuous supporting belt for supporting and conveying a respective sheet of cardboard; and actuating means for moving said at least one supporting belt along a predetermined path; the machine being characterized in that said at least one supporting belt is defined by a mat made of multispiral fabric in direct contact with said respective sheet of cardboard.
- the present invention therefore relates to the use of a mat of multispiral fabric as a belt for supporting and/or conveying a sheet of cardboard on a corrugated cardboard manufacturing machine.
- multispiral fabric is intended to mean a commonly known fabric normally
- the lighter weight of multispiral fabrics as compared with felt or conventional fabrics also makes for easier handling and for easier, faster assembly to the corrugating machine.
- Multispiral fabrics have also been found to be much more permeable than felt or conventional fabrics, thus enabling fast, effective dispersion of the steam issuing from the cardboard during processing. Effective evaporation also enables a smaller amount of glue to be applied to the cardboard.
- the even thickness of multispiral fabric mats also enables accurate pressure transmission to the cardboard by the pressure plates on the corrugating machine, thus ensuring perfect gluing, even at high production speeds and using thin ("microcorrugated") cardboard. Even at high machine operating speeds, it is therefore possible to obtain top-quality finished products, even of small thickness, perfectly suitable for boxes or packages for select items (in particular, perfume, ornaments, etc.).
- Multispiral fabrics have been found to produce corrugated cardboard of any type, with no restrictions as to composition or weight, while at the same time permitting relatively high production speeds and excellent finished product quality.
- the surface structure of the multispiral mat is such as to permit fast, easy cleaning with no danger of damaging the surface.
- the multispiral mat is also of considerable dimensional stability, which eliminates any risk of excessive in-service stretching or shrinking of the supporting belt which might impair operation of the corrugating machine and the quality of the finished cardboard. Finally, the multispiral mat is perfectly homogeneous with no variations in thickness or physical- mechanical characteristics at the joints, which are even with the rest of the surface of the mat, thus preventing any marked impressions or unevenness in the finished cardboard.
- Table 1 below shows the most significant results of comparative tests conducted on conventional corrugated cardboard manufacturing machines using supporting belts made of felt or conventional fabrics and belts of multispiral fabrics according to the invention.
- Table 1 confirms the advantages already mentioned with respect to felt or conventional fabrics.
- using multispiral mats according to the invention which are much thinner, lighter and permeable than felt or conventional fabrics, provides for a significant reduction in the energy consumption of the corrugating machine and in the amount of glue used.
- Figure 1 shows, schematically, the known structure of a multispiral fabric mat for use in accordance with the invention
- Figure 2 shows a schematic longitudinal view of the overall structure of a corrugated cardboard manufacturing machine employing the Figure 1 mat .
- Figure 1 shows schematically a portion of a mat of multispiral fabric 1 of commonly known type and described, for example, in the aforementioned patents incorporated herein purely by way of reference.
- the multispiral fabric preferably made of synthetic polymer fibers, is defined by a number of spirally wound helical bands 2 , which are arranged side by side longitudinally with the relative turns penetrating one another, and are connected to one another by connecting yarns 3 inserted through the adjacent turns of the bands .
- FIG. 2 shows schematically a known corrugated cardboard manufacturing machine 10, both the structure and operation of which are known and therefore not described in detail for the sake of simplicity.
- machine 10 substantially comprises a first continuous top supporting belt 11 and a second continuous bottom supporting belt 12 for supporting and conveying respective cardboard sheets (not shown) ; and actuating means 13 , 14 for moving respective supporting belts 11, 12 along respective predetermined, at least partly superimposed paths. More specifically, actuating means 13 bring supporting belt 11 into direct contact with a top face of the relative cardboard sheet, and actuating means 14 bring supporting belt 12 into direct contact with a bottom face of the relative cardboard sheet.
- actuating means 13, 14 comprise respective powered draw cylinders 15, 16 and respective numbers of tensioning and/or transmission rollers 17, 18.
- Machine 10 also comprises a number of pressure plates 19, possibly arranged in separate groups, for exerting a predetermined pressure on the cardboard sheets; and heating means 20, e.g. heating surfaces, for heating the cardboard sheets .
- supporting belt 11 is defined by a mat of multispiral fabric of the type shown in Figure 1 and appropriately cut and joined. As is known, joining adjacent portions of a multispiral fabric of this type produces no alteration in thickness and no unevenness of any sort.
- Supporting belt 12 may also be defined by a mat of multispiral fabric, possibly modified to improve adhesion to the cardboard.
