Device for adjusting pressure applied to a varnishing cylinder of a varnishing machine

A device for adjusting pressure applied to a varnishing cylinder of a varnishing machine including a frame, a varnishing cylinder having two opposite supports, a pressure cylinder for applying pressure to a workpiece movable between the varnishing and pressure cylinders and likewise having two opposite supports, and a varnish feed roller, the pressure adjusting device comprising:

• two auxiliary side members pivotally attachable to the frame for supporting the opposite supports of one of the varnishing cylinder and the pressure cylinder;
• first means for adjusting pressure between the varnishing and pressure cylinders, the pressure adjusting means including two first tilting motor spindles for pivoting the two auxiliary side members and having respective one ends thereof attachable to the frame and respective another ends thereof attachable to the two auxiliary side members, respectively;
• two spaced support flanges for supporting the varnish feed roller;
• second means for adjusting pressure between the varnishing cylinder and the varnish feed roller, the second pressure adjusting means including two second tilting motor spindles for pivoting the two support flanges, respectively, and having respective one ends thereof attachable to one of the frame and an auxiliary side member, and respective another ends thereof attachable to respective support flanges;
• pressure sensor means supported on the auxiliary side members for sensing axial pressure applied by each of the first and second motor spindles to respective auxiliary side members and support flanges;
• and
• pressure regulator means connected with the pressure sensor means for controlling the axial pressure applied by a respective motor spindle to a predetermined constant value.
