Abstract: A lubricating device for the revolving flat arrangement of a carding machine having two chains arranged at the sides of the card and engaging ends of the revolving flats. The chains move in a loop and are guided by stationary guides at least in the area of the card cylinder and slide surfaces of the flats slide along these guides. At least one lubricant container is provided at each side of the revolving flat arrangement and is responsible for the dosed lubrication of the sliding surfaces. A rotatable transfer element associated with the appropriate lubricant container comes into contact with the lubricant and the sliding surfaces and is driven from the appropriate chain via a gear wheel.
