Abstract
A doctor blade system with clamping device is provided for clamping a doctor blade, for example, in a doctor blade chamber without using screws and without having to use tools. A clamping mechanism, preferably pneumatic, counteracts the clamping by actuation. By disposing a sectional rail between the clamping rail and the doctor beam, the sectional rail drawing the clamping rail and the beam together with a spring mechanism, the doctor blade is clamped between the clamping rail and the beam. In another embodiment, the clamping rail is designed as an angular section tipping about an edge.
Claims18
A doctor blade system for printing presses, comprising doctor beam, clamping rail and doctor blade, together with clamping device for fastening the doctor blade between the clamping rail and the doctor beam, where the clamping device forms a mechanical connection between the clamping rail and the doctor beam, which connection is continuous largely over the whole length of the doctor blade, wherein the clamping device also comprises a displacing mechanism which by actuation counteracts the clamping so that the doctor blade thereby is no longer clamped between the clamping rail and the doctor beam.
A clamping device for a doctor blade in a printing press, comprising doctor beam and clamping rail between which the doctor blade is clamped, wherein the clamping device by which the clamping is provided is elongate and form a mechanical connection between the clamping rail and the beam, which connection is continuous largely over the whole length of the doctor blade, and that the clamping device also comprises a displacing device which by actuation counteracts the clamping.
