The lubrication device (1) includes an extruded profile (3), through which run lubricant ducts (41) and at least one carrier medium duct (42), at least one connection block (5, 6) and nozzles (7). The connection block (5, 6) is connected to the extruded profile (3) and has lubricant connection ducts (54) that are each connected to one lubricant duct (41) of the extruded profile (3). The nozzles (7) are connected to the extruded profile (3) and are designed to create and emit a lubricant-carrier medium mixture consisting of lubricant and a carrier medium. ## Claims ### Claim 1 A lubricating device for applying a lubricant when rolling a rolling material, the lubricating device comprising: an extruded profile with two oppositely disposed profile ends, a plurality of lubricant ducts which extend between and are open to both profile ends, and at least one carrier-medium duct, which is open to both profile ends and extends through the extruded profile; a connection block for one of the profile ends, the connection block is connected to the extruded profile at the one of the profile ends, the connection block has lubricant connecting ducts and each lubricant connecting ducts is connected to a lubricant duct of the extruded profile; and a plurality of nozzles connected to the extruded profile, each nozzle is connected to one of the lubricant ducts and to at least one of the carrier-medium ducts of the extruded profile, and each nozzle is configured for creating and delivering a lubricant-carrier medium mixture consisting of the lubricant and a carrier medium. ### Claim 2 (depends on 1) The lubricating device as claimed in claim 1, further comprising at least one of the connection blocks has one of the carrier-medium connecting ducts connected to at least one carrier-medium duct of the extruded profile. ### Claim 3 (depends on 1) The lubricating device as claimed in claim 1, wherein the extruded profile is comprised of aluminum, copper, an aluminum alloy or a copper alloy. ### Claim 4 (depends on 1) The lubricating device as claimed in claim 1, further comprising each nozzle is connected to a lubricant duct of the extruded profile via at least one branch duct which has been drilled from an outside into the extruded profile. ### Claim 5 (depends on 4) The lubricating device as claimed in claim 4, further comprising each branch duct of the extruded profile is closed off to the outside of the branch duct by a blanking plug. ### Claim 6 (depends on 1) The lubricating device as claimed in claim 1, further comprising each nozzle is detachably connected to the extruded profile by a bayonet connection or by means of a screwed connection. ### Claim 7 (depends on 1) The lubricating device as claimed in claim 1, further comprising the connection block has a lubricant deflection segment including lubricant lines which each connect one of the lubricant connecting ducts of the connection block to one of the lubricant ducts of the extruded profile and deflect the lubricant in the profile. ### Claim 8 (depends on 7) The lubricating device as claimed in claim 7, further comprising the lubricant deflection segment includes a plurality of plates arranged in a stack, the plates have cutouts therethrough and the cutouts of successive plates form the lubricant lines. ### Claim 9 (depends on 7) The lubricating device as claimed in claim 7, further comprising the lubricant deflection segment includes a plurality of plates arranged in a stack and a seal which is arranged on the plate stack, wherein the plates and the seal have respective cutouts therethrough and the cutouts of successive plates and the seal form the lubricant lines. ### Claim 10 (depends on 1) The lubricating device as claimed in claim 1, further comprising: a control valve arranged outside the extruded profile that is connected to each of the lubricant ducts of the extruded profile. ### Claim 11 (depends on 1) The lubricating device as claimed in claim 1, further comprising: another connection block connected to the other end of the extruded profile, wherein the other connection block has lubricant connecting ducts each connected to a lubricant duct of the extruded profile. ### Claim 12 (depends on 11) The lubricating device as claimed in claim 11, further comprising both connection blocks have a respective carrier-medium connecting duct which is connected to one of the carrier-medium ducts of the extruded profile. ### Claim 13 (depends on 1) The lubricating device as claimed in claim 1, further comprising a nozzle protection frame, including a respective recess for each of the nozzles, and each recess is arranged in the extruded profile around the respective nozzle. ### Claim 14 (depends on 1) A method for producing a lubricating device as claimed in claim 1, wherein the extruded profile is produced by producing a semi-finished product, with the lubricant ducts and the at least one carrier-medium duct, wherein the producing is performed in an extrusion process; by cutting the semi-finished product to a length which depends on an extent of a lubricating region which is to be lubricated; by introducing recesses for each of the nozzles introduced into the semi-finished product; and by forming at least one branch duct into the extruded profile from an outer surface of the semi-finished product for each nozzle recess, for enabling connection of the nozzle recess to a lubricant duct which extends through the extruded profile.
