Abstract
A detachable inking device for a flexographic printing machine, a manipulating device for removing and replacing the inking device, a cleaning device, and a repair station for refurbishing the inking device. The inking device itself is a chambered doctor blade ( ) mounted on two lever-supports ( ) through which ink is supplied from a reservoir. The lever-supports are rigidly attached to a shaft ( ) which is pivotable between the frames ( ) of the flexographic printing machine. The chambered doctor blade has a body ( ) made of light material, crossed at one of its ends by a tube ( ) emerging from the bottom ( ) of body ( ), and at the other end by a tube ( ) having its opening part ( ) at level with the bottom ( ) of the body ( ). The latter rests on seals ( ) secured to the lever-supports ( ) to which are attached centering and fixing means ( ) allowing a quick loosening of the chambered doctor blade ( ) without the help of any tool. The body ( ) comprises two planar outwardly slanted projecting parts against which are adhesively attached two doctor blades elements. The doctor blade elements are also held at their ends by a supporting piece ( ) having two supporting flanges ( ) that engage the ends of the doctor blade elements ( ).
