METHOD FOR FITTING A BANDEROLE ON THE CIRCUMFERENCE OF CHEESES

Abstract: A method for fitting a banderole on the circumference of shaped cheeses, in which after the ripening process and cheese plastic has been placed thereon, the cheeses are lightly moistened on the circumference on the cheese plastic, through which said cheese plastic softens on its surface thereby fixing the banderole wound round the respective cheeses. The winding with the banderole is carried out automatically with a banderole of light tissue paper or teabag paper, which is previously moistened. The moisture can be water with a solvent such as a fungicide. A device for carrying out this method is provided at least with a cheese conveyor duct (1) having a flat conveyor belt (5) and two longitudinal duct walls (5,6,), one of which consists of a continuously driven conveyor belt, while the other is a stationary wall, and a banderole feed device (12) with a banderole supply roll (20) and a banderole apportioning element, in addition to means for feeding in the banderole at the cheese infeed end of the conveyor belt. An auto­ matic moisture-dosing element (26) is fitted near the cheese infeed end of the conveyor belt (5) for the purpose of moistening the banderole (8).

Description: The invention relates to a method for fitting a banderole on the circumference of shaped cheeses. The device for carrying out the above-mentioned method is provided with a cheese conveyor duct, having a flat conveyor belt and two longitudinal duct walls, one of which consists of a continuously driven conveyor belt, while the other is a stationary wall, and a banderole feed device with a banderole supply roll and a banderole apportioning element, in addition to means for feeding in the banderole at the cheese infeed end of the conveyor belt. The above-mentioned method and device are known from Dutch Patent Specification 180898. In the method and device known from the above-mentioned patent specification softer and semi-hard unmatured cheeses have a banderole or "sleeve" of strong paper, such as thick teabag paper, wound round them in order to prevent sagging and changing of shape in the maturing phase. This banderole or supporting sleeve, about 5 - 7 cm wide and being a weight of 14-28 g/m², is stuck to the cheese with a thinned potato flour solution or adhesive. It is also known in the case of fully matured cheeses which have been provided once or more with cheese plastic then to decorate them with a narrower decorative banderole generally made of very light tissue paper or teabag paper. This decorative banderole is then placed by hand on the still wet cheese plastic, which serves as adhesive. This method, which discloses all the features of the preamble of claim 1 generally takes place in the cheese warehouses before the cheeses are despatched, is carried out for purposes of advertising and identification. This manual decoration or printing of a cheese is relatively expensive, since it requires great manpower to place the banderoles on the cheeses, because one person can handle at the most only 100 cheeses per hour. It is also very difficult and sometimes impossible always to wind the banderole tightly and crease-free round the cheese. Moreover, after this banderoling, the cheese plastic, which then also serves as the adhesive, has to dry for some time before the final packing or paraffin-coating of the cheese can take place in the cheese warehouse. The object of the invention is to eliminate these problems and to provide a method with which a decorative banderole can be placed on shaped cheeses automatically in a quick and effective manner. This is achieved with a method of the type mentioned in the preamble according to the invention such that, after the ripening process of said cheeses being provided on their surface with cheese plastic, a slight moistening is used intended for the cheese plastic to soften and that the banderole is wound round the cheeses being fixed by the softened cheese plastic. In this method according to the invention the moisture is applied directly on the cheese plastic before the banderole is wound round the cheeses or the moisture is previously applied on the banderole, being of light tissue paper or tea bag paper, before it is automatically winded around the cheeses. In fact, surprisingly it has been found that such a slight moistening of the banderole before it is winded round the cheese - or a slight moistering directly of the cheese plastic - is sufficient to soften said cheese plastic on the surface and thereby fix the banderole straight and without creases. A great advantage with this method is that the device used for carrying out above-mentioned method, which device is usually provided with a cheese conveyor duct, having a flat conveyor belt and two longitudinal duct walls, one of which consists of a driven conveyor belt, while the other is a stationary wall, and a banderole feed device with a banderole supply roll and a banderole apportioning element, in addition to means for feeding in the banderole at the cheese infeed end of the conveyor belt, does not become soiled. Such soiling does occur otherwise to a considerable degree if there is an automatic decoration during the applying of the cheese plastic. The invention will be explained in greater detail with reference to an embodiment shown in the figure. In the figure, reference number 1 indicates a conveyor duct for cheeses 2, which are shown in a number of characteristic positions. The conveyor duct 1 is provided with a horizontal conveyor face 3 and longitudinal walls 5 and 6. The wall 6 is essentially a stationary wall, and the wall 5 is largely formed by a conveyor belt. The stationary wall 6 is connected to the frame of the device by spring means which press the wall 6 in the direction of the opposite wall. Reference number 9 indicates the infeed section on which the cheeses are fed in. The conveyor belt 5 runs over a number of pulleys 10 and 11, one of which is driven by a motor (not shown). The banderole feed device is indicated in its entirety by 12. The banderole strip 8 is fed to the conveyor duct from a banderole supply roll 20 via a compensation arm 22, which is arranged so that it pivots about an axis 21, and via a press means with two pressure rollers 23, 24 and a perforation device 25. The banderole strip is apportioned and wound round the cheeses in a manner not shown in any further detail. The banderole, which is decorated or printed, is of very light tissue paper or teabag paper about 10-14 g/m² in weight and about 2.5-6.0 cm in width. The matured cheeses, which have been provided with cheese plastic one or more times, are fed in via the infeed section 9. A moisture-dosing element 26 is disposed near the pulley 11 and moistens the banderole at the fastening side with a minimal quantity of moisture, for example water. Through this slight moistening of the banderole, the outer surface of the cheese plastic will become soft when the banderole is being fitted and its adhesive action will fix the banderole tightly and free from creases. Alternatively it is also possible - preceding the winding of the banderole - to lightly moisten the cheese per se, i.e. the cheese plastic on the circumference of the cheese. This can be done for instance with a moistened sponge or soft roller. Thereby, as above, the outer surface of the cheese plastic will become soft and will fix the banderole, when wound, through its adhesive action. In certain cases the cheeses also have to be paraffin-coated immediately after banderoling, i.e. they must be provided with a layer of paraffin in a "paraffin pot". Since moisture on the cheese under the paraffin causes staining or mould, only a minimal amount of moisture must be applied to the banderole or, alternatively, on the cheese plastic on the cheese circumference. For this purpose the moisture-dosing element, for example a sprayer or atomizer, meters very accurately, e.g. with a quantity of water of one cc per 400 m² decorative banderole. The moisture used in the dosing element can be pure water, but can also be water with a solvent, such as a fungicide. In view of the weakness of the banderole paper used and the fact that this paper hardly absorbs any moisture, the banderole can also be supported during conveyance and when at a standstill by a supporting element 27. By means of the above-mentioned method and device it is possible to provide a banderole quickly and automatically on, for example, cheeses with a diameter of 25 to 50 cm.
