Description
La présente invention concerne un ensemble pour presse rotative, du type comprenant
- un moyeu adapté pour être monté en rotation autour d'un axe central dans une presse rotative et présentant une surface extérieure,
- un manchon d'adaptation de format destiné à être monté sur le moyeu et comprenant une surface intérieure adaptée pour s'appliquer sur la surface extérieure du moyeu,
- des moyens de fixation du manchon d'adaptation au moyeu.
- a hub adapted to be rotatably mounted about a central axis in a rotary press and having an outer surface,
- a size adapter sleeve for mounting on the hub and having an inner surface adapted to be applied to the outer surface of the hub,
- means for fixing the adapter sleeve to the hub.
Dans une presse rotative, la longueur circonférentielle de la plaque à imprimer est un paramètre limitant le format ou la longueur d'impression du produit à imprimer. Afin d'augmenter la flexibilité de la presse, il est nécessaire de permettre une variation de longueur d'impression ou une variation de format.In a rotary press, the circumferential length of the plate to be printed is a parameter limiting the format or the printing length of the product to be printed. In order to increase the flexibility of the press, it is necessary to allow a variation of printing length or a variation of format.
Afin de modifier la longueur circonférentielle d'un cylindre ayant un rayon fixe dans une presse, des manchons d'adaptation ouverts ayant différentes épaisseurs peuvent être montés sur un moyeu. Un tel manchon est par exemple divulgué dans la demande
La réalisation d'un mécanisme de tension destiné à tendre un tel manchon ouvert autour d'un moyeu cylindrique est complexe du fait de la nécessité d'éviter que les bords de tête et de queue du manchon ne se soulèvent du moyeu sous l'effet de l'effort de tension.The realization of a tension mechanism intended to tension such an open sleeve around a cylindrical hub is complex because of the need to prevent the head and tail edges of the sleeve from being lifted from the hub under the effect the tension force.
Il est par ailleurs connu de dilater un manchon d'adaptation fermé par un coussin d'air afin de pouvoir le monter sur le moyeu de la presse. Toutefois, la dilatation d'un manchon fermé demande une pression très importante ou implique l'utilisation d'un manchon à la fois élastique et incompressible, ce qui sont des propriétés de matière généralement incompatible.It is also known to expand an adapter sleeve closed by an air cushion so as to mount it on the hub of the press. However, the expansion of a closed sleeve requires a very high pressure or involves the use of a sleeve both elastic and incompressible, which are properties of generally incompatible material.
C'est pourquoi l'invention a pour but de pallier les inconvénients cités et de fournir un ensemble comprenant un manchon d'adaptation et un moyeu, le manchon étant facile à monter sur le moyeu.This is why the invention aims to overcome the drawbacks mentioned and to provide an assembly comprising an adapter sleeve and a hub, the sleeve being easy to mount on the hub.

A cet effet, le moyeu 4 comporte une extrémité commande 10, reliée à des moyens d'entraînement, tel qu'un moteur électrique, ainsi qu'une extrémité fonction 12.The hub 4 and the
Le moyeu 4 comporte une surface extérieure centrale 14, qui a une forme cylindrique à section circulaire centrée sur l'axe central X-X. Il comporte en outre une surface de butée 16, se raccordant à la surface extérieure centrale 14 côté extrémité commande. La surface de butée 16 a une forme tronconique d'axe X-X s'évasant vers l'extrémité commande 10. Le moyeu 4 comporte en outre une surface de portée 18, qui se raccorde à la surface extérieure cylindrique centrale 14, côté extrémité fonction 12. Cette surface de portée 18 a une forme tronconique d'axe X-X se rétrécissant vers l'extrémité fonction 12.The hub 4 has a central
Il est à noter que la surface de butée 16 et la surface de portée 18 se raccordent chacune d'une manière non étagée à la surface extérieure centrale 14 cylindrique. En d'autres termes, les diamètres des surfaces de butée 16 et de portée 18, à leur extrémité tournée vers la surface extérieure centrale 14 sont identiques au diamètre de la surface 14.It should be noted that the
Comme ceci est illustré sur la

La surface intérieure centrale 24 a la même longueur axiale que la surface extérieure centrale 14. Ainsi, la surface intérieure 24 est adaptée pour s'appliquer sur la surface extérieure 14 du moyeu 4.As shown in Figs 1 and 3, the
