Abstract
A varnishing machine having an arrangement for adjusting pressure between the varnishing and pressure cylinders and for compensating changes in rotational speed of the varnishing cylinder caused by soaking of the varnishing cylinder shell and/or regrinding of the varnishing cylinder, with the arrangement including two auxiliary side members for supporting the varnishing cylinder or pressure cylinder, two motor spindles for pivoting the two side members, respectively, pressure sensors for sensing the axial pressures applied by the two-motor spindles, a pressure regulator for controlling the applied pressures and thereby the pressure between the varnishing and pressure cylinders, and displacement sensor for sensing an angular position of one of the side members, the position signal generated by the displacement sensor being used as a control variable for controlling the rotational speed of the varnishing cylinder.
