Abstract
Description
Cette invention concerne un ensemble calandrage, comme par exemple une supercalandre, ayant au moins une zâne de pincement souple et comportant au moins deux rouleaux tournants fermement appuyés l'un contre l'autre, et prévus pour qu' une bande de papier passe entre eux, l'un au moins des rouleaux étant entrai né de manière à entraîner par friction les autres rouleaux par l'intermédiaire de zônes de pincement formées entre rouleaux adjacents. This invention relates to a calendering assembly, such as for example a supercalender, having at least one flexible pinch strip and comprising at least two rotating rollers firmly pressed against each other, and provided so that a strip of paper passes between them , at least one of the rollers being entrained so as to frictionally drive the other rollers by means of pinch zones formed between adjacent rollers.
Ces ensembles de calandrage sont utilisés pour glacer une bande de papier. These calendering sets are used to glaze a strip of paper.
Les réalisations antérieures connues produisent le glaçage de la bande de papier dans des ensembles de calandrage dans lesquels la bande est menée à travers des zônes de pincement formées par des paires de rouleaux successives, tandis que les supercalandres classiques comportent des rouleaux superposés entre lesquels la bande circule en faisant des méandres. Dans les ensembles de calandrage, tous les rouleaux sont en acier ; dans les supercalandres, un rouleau sur deux est souple et fabriqué à partir de roues en tissu de coton qui sont montées sur un arbre en acier et fortement comprimées en direction axiale. Ensuite, le rouleau comprimé est usiné jusqu'à sa forme finale par tournage.Le rapport du diamètre de l'arbre à celui du rouleau est généralement de 50 ... 70 . Dans une supercalandre conforme à la figure 1, une bande de papier 1 est prévue pour passer entre des rouleaux K, P en formant des méandres. La tension de la bande est réglée ajustée au moyen de rouleaux auxiliaires 6 disposés en parallèle avec les rouleaux durs et souples. Les parties alternées de rouleaux durs K et souples P qui sont appuyés les uns contre les autres, produisent des zônes de pincement souples qui facilitent le supercalandrage de la bande de papier. The known prior embodiments produce the glazing of the paper strip in calendering assemblies in which the strip is led through pinch zones formed by pairs of successive rollers, while the conventional supercalender comprises superposed rollers between which the strip circulates by making meanders In the calendering assemblies, all the rollers are made of steel; in supercalender, every other roller is flexible and made from cotton fabric wheels which are mounted on a steel shaft and strongly compressed in the axial direction. The compressed roller is then machined to its final shape by turning.The ratio of the diameter of the shaft to that of the roller is generally 50 ... 70. In a supercalender conforming to FIG. 1, a strip of paper 1 is provided to pass between rollers K, P by forming meanders. The belt tension is adjusted adjusted by means of auxiliary rollers 6 arranged in parallel with the hard and flexible rollers. The alternating parts of hard rollers K and flexible rolls P which are pressed against each other, produce flexible pinch zones which facilitate the super-calendering of the paper strip.
Conformément à la figure 2, dans un ensemble de calandrage selon la technologie de l'art antérieur, la bande de papier 1 est prévue pour passer à travers les zônes de pincement 3 de paires de rouleaux successives qui comprennent deux paires de rouleaux durs K.In accordance with FIG. 2, in a calendering assembly according to the technology of the prior art, the paper strip 1 is provided to pass through the nip areas 3 of pairs of successive rollers which comprise two pairs of hard rollers K.
Un ensemble de calandrage avec des rouleaux en acier ne réalise pas un glaçage aussi bon qu'une supercalandre. D'autre part, une supercalandre est une solution relativement coûteuse comparée à un ensemble de calandrage, et, de plus, le rouleau souple de la supercalandre est, à présent, la partie risquant le plus d'être endommagée. A calendering assembly with steel rollers does not achieve icing as good as a supercalender. On the other hand, a supercalender is a relatively expensive solution compared to a calendering assembly, and, in addition, the flexible roller of the supercalender is now the part most at risk of being damaged.
La présente invention a pour but d'éviter les inconvénients des méthodes précédentes et de prévoir un type d'ensemble de calandrage entièrement nouveau comme par exemple une supercalandre. The object of the present invention is to avoid the drawbacks of the preceding methods and to provide an entirely new type of calendering assembly such as for example a supercalender.
L'invention est basée sur le remplacement du rouleau dur ou souple par deux rouleaux, de préférence durs, sur lesquels circule une courroie sans fin. The invention is based on the replacement of the hard or flexible roller with two, preferably hard, rollers on which an endless belt circulates.
De façon plus précise, l'ensemble de calandrage conforme à la présente invention est caractérisé par au moins une combinaison d'éléments prévue pour former une zône de pincement souple et comportant un rouleau dur, au moins un rouleau auxiliaire parallèle au rouleau dur, et une courroie sans fin adaptée pour circuler sur le rouleau dur et chacun des rouleaux auxiliaires. More specifically, the calendering assembly according to the present invention is characterized by at least one combination of elements intended to form a flexible nip area and comprising a hard roller, at least one auxiliary roller parallel to the hard roller, and an endless belt adapted to circulate on the hard roller and each of the auxiliary rollers.
L'invention procure des avantages remarquables. The invention provides remarkable advantages.
L'ensemble de calandrage conforme à l'invention a le principal avantage d'assurer à un cot raisonnable, un glaçage équivalent à celui obtenu par une supercalandre. The calendering assembly according to the invention has the main advantage of ensuring, at a reasonable cost, icing equivalent to that obtained by a supercalender.
Dans une supercalandre conforme à l'invention, la courroie est plus facile à changer dans le but de modifier le degré de finition du papier. Une courroie endommagée peut être réparée par des méthodes d'abrasion sans l'enlever de la machine. De plus, la courroie est plus flexible qu'un rouleau, de sorte que la pression est distribuée plus uniformément dans la zône de pincement que dans les solutions de l'art antérieur. In a supercalender according to the invention, the belt is easier to change in order to modify the degree of finish of the paper. A damaged belt can be repaired by abrasion methods without removing it from the machine. In addition, the belt is more flexible than a roller, so that the pressure is distributed more uniformly in the nip area than in the solutions of the prior art.
L'invention est décrite plus en détail ci-dessous à l'aide des exemples de réalisation conformes aux figures 3 à 5 annexées, dans lesquelles
- la figure 3 est une vue de côté du cheminement de la bande de papier dans une supercalandre conforme à l'invention
- la figure 4 est une vue de côté du cheminemement de la bande de papier dans un ensemble de calandrage conforme à l'invention
- la figure 5 est une vue de côté du cheminement de la bande de papier dans un autre ensemble de calandrage conforme à l'invention.The invention is described in more detail below with the aid of the exemplary embodiments in accordance with FIGS. 3 to 5 appended, in which
- Figure 3 is a side view of the path of the paper strip in a supercalender according to the invention
- Figure 4 is a side view of the routing of the paper strip in a calendering assembly according to the invention
- Figure 5 is a side view of the path of the paper strip in another calendering assembly according to the invention.
La figure 3 illustre une réalisation possible d'un appareil conforme à l'invention. Une bande de papier 1 est prévue pour passer à travers une zône de pincement 3 formée par des rouleaux durs 2 et 7 agencés de manière à former la zone de pincement souple 3 au moyen d'une courroie 5 qui est prévue pour circuler sur le rouleau dur 7 et un rouleau auxiliaire 4 disposé en parallèle avec ledit rouleau dur. Le rouleau auxiliaire 4 dont l'axe longitudinal est parallèle aux rouleaux durs 2, 7 est prévu pour tourner du côté opposé aux rouleaux auxiliaires 6 qui tendent la bande de papier 1. La courroie 5 est fabriquée à partir de tout matériau élastique connu comme, par exemple, du caoutchouc ou du plastique.Le rouleau dur 2 est appuyé contre la courroie 5, et, comme les rouleaux tournent librement, leur entraînement en rotation étant obtenu par friction au niveau de la zone de pincement 3, à partir d'un rouleau situé en-dessous d'eux, un différentiel de vitesse est engendré entre les rouleaux de sorte que la surface de la bande de papier 1 est glacée. En modifiant le matériau de la couroie 5, la longueur de la zone de pincement 3 et la pression exercée sur la bande de papier 1 peuvent être réglés. Figure 3 illustrates a possible embodiment of an apparatus according to the invention. A strip of paper 1 is provided to pass through a nip area 3 formed by hard rollers 2 and 7 arranged so as to form the flexible nip area 3 by means of a belt 5 which is intended to circulate on the roller hard 7 and an auxiliary roller 4 arranged in parallel with said hard roller. The auxiliary roller 4, the longitudinal axis of which is parallel to the hard rollers 2, 7 is intended to rotate on the opposite side to the auxiliary rollers 6 which tension the paper strip 1. The belt 5 is made from any elastic material known as, for example, rubber or plastic. The hard roller 2 is pressed against the belt 5, and, as the rollers rotate freely, their rotational drive being obtained by friction at the nip 3, from a roller located below them, a speed differential is generated between the rollers so that the surface of the paper strip 1 is glazed. By changing the material of the belt 5, the length of the nip 3 and the pressure exerted on the paper strip 1 can be adjusted.
La figure 4 illustre une réalisation possible d'un ensemble de calandrage conforme à l'invention. Dans cette réalisation, le second rouleau dur 2 de chaque paire de cylindres représentée sur la figure 2, est remplacé par une combinaison qui comporte un rouleau auxiliaire 4, une courroie souple 5, et un rouleau dur 7. Du fait que ces combinaisons de composants sont situées d'un même côté de la bande de papier 1, on obtient un glaçage sur une seule face de ladite bande de papier. Figure 4 illustrates a possible embodiment of a calendering assembly according to the invention. In this embodiment, the second hard roller 2 of each pair of cylinders shown in FIG. 2, is replaced by a combination which comprises an auxiliary roller 4, a flexible belt 5, and a hard roller 7. Because these combinations of components are located on the same side of the paper strip 1, one obtains a glaze on one side of said paper strip.
La figure 5 illustre une réalisation d'un ensemble de calandrage qui produit un glaçage sur les deux faces de la bande de papier parce que, dans cette réalisation, les combinaisons de rouleaux et courroies 4, 5, 7 sont situées sur des faces opposées de la bande de papier 1. FIG. 5 illustrates an embodiment of a calendering assembly which produces a glaze on the two faces of the paper strip because, in this embodiment, the combinations of rollers and belts 4, 5, 7 are located on opposite faces of the strip of paper 1.
La portée de l'invention s'étend à des réalisations différentes de celles décrites ci-dessus. En conséquence, l'un des rouleaux auxiliaires 4 peut être remplacé par deux ou plusieurs rouleaux auxiliaires 4, de sorte que la courroie sans fin 5 est prévue pour circuler sur tous les rouleaux auxiliaires. The scope of the invention extends to embodiments different from those described above. Consequently, one of the auxiliary rollers 4 can be replaced by two or more auxiliary rollers 4, so that the endless belt 5 is provided to run on all the auxiliary rollers.
