    摘要: A chambered doctor blade device intended for a printing unit and adapted to coat a rotatable cylinder (2) with ink, lacquer, adhesive or the like, comprises an elongate frame (8) which is arranged parallel to and outside the cylinder (2) and on which are mounted two parallel, elongate and spaced-apart doctor blades (9,10) to be resiliently and scrapingly applied against the cylinder (2) in operative position. An elongate chamber (11) holding ink (12) or the like is defined by the doctor blades (9,10), the surface of the frame (8) facing the cylinder (2), and the circumferential surface of the cylinder (2). To achieve good flexural and torsional rigidity, the frame (8) comprises at least two elongate interconnected metal sections (13,14) which are made of bent thin sheet-metal, preferably of stainless steel, and by means of which the elongate portion of the frame (8) located between the mounting places for the doctor blades (9,10) forms an elongate stiffening or reinforcing portion. Such a frame (8) ensures, in operation, a set constant distance between the frame (8) and the cylinder (2) and, consequently, constant application of the doctor blades (9,10) against the cylinder (2).

    摘要: A device is designed to sealingly close an end of a chambered doctor blade (K). The chambered doctor blade (K,) has an elongate frame (K1) and two elongate doctor blades (K6, K7), which are arranged on the frame (K1) and define, together with the latter, an elongate chamber (K10), which is adapted to hold, for instance, ink. The chambered doctor blade (K) has an elongate opening (K11) for abutment, in an operative position of the chambered doctor blade (K), against a rotatable cylinder (V) included in a printing unit. The end sealing device comprises first and second sealing sheets (20, 30) which are mountable to at least partially overlap each other and sealingly close an opening (K11) in one end of said chamber (K10). The sealing sheets (20, 30) are arranged relative to each other in such manner that the first sealing sheet (20) is sealingly applicable against said frame (K1) and, in the operative position of the chambered doctor blade (K), is located at a distance from a circumferential surface of said cylinder (V) and in such manner that the second sealing sheet (30) is sealingly applicable against said doctor blades (K6, K7), and, in the operative position of the chambered doctor blade (K), abuts against said circumferential surface.
