The present invention relates to a rolling stand for rolling metallic strips with at least one roll (2, 3, 5, 6) or roller which is mounted in the region of its end journals (7, 8) in each case in a roller bearing (9, 10), and with at least one distributor device (V1-V6) for distributing a lubricant gas flow (L), and to a roll (2, 3, 5, 6) or roller for a rolling stand (1) of this type. The rolling stand according to the invention makes it possible in a simple and operationally reliable manner to supply a precisely determined lubricant quantity to a roller bearing which is provided for mounting a shaft or roller. According to the invention, this is achieved by the fact that a connecting channel (22, 122) for the transport of a lubricant gas flow (L) to or from the distributor device (V1-V6, V101, V102) is formed in the roll (2, 3, 5, 6) or roller.

La présente invention concerne une cage de laminoir pour laminer des bandes métalliques, comprenant au moins un cylindre 2, 3, 5, 6 ou rouleau, lequel est à chaque fois monté dans un palier de roulement 9, 10 dans la zone de ses tourillons d'extrémité 7, 8, et comprenant au moins un dispositif de distribution V1-V6 pour distribuer un flux de gaz lubrifiant L, ainsi qu'un cylindre 2, 3, 5, 6 ou rouleau pour ladite cage de laminoir 1. La cage de laminoir selon l'invention permet d'acheminer en toute simplicité et en toute sécurité une quantité de lubrifiant dosée avec précision à un palier à roulement conçu pour supporter un arbre ou un rouleau. Conformément à l'invention, cette opération est réalisée en ce qu'un canal de liaison 22, 122 destiné au transport d'un flux de gaz lubrifiant L est aménagé dans le cylindre 2, 3, 5, 6 ou le rouleau vers ou depuis le dispositif de distribution V1-V6, V10l, V102.
