Abstract

Per il comando della pressione applicata dai cilindri portaforma di dispositivi stampanti di una macchina da stampa, preferibilmente di una macchina da stampa flessografica, ad un cilindro di contropressione comune, i cilindri portaforma, supportati su slitte spostabili da azionamenti in guide fisse sull'incastellatura, sono accostabili a questo ed allontanabili da questo. Per assicurare una pressione applicata sostanzialmente costante anche nel caso in cui il cilindro di contropressione non sia perfettamente cilindrico, le acircolaritá del cilindro di contropressione, partendo da una posizione zero, vengono misurate in dipendenza degli angoli di rotazione lungo il suo perimetro ed i cilindri portaforma vengono spostati nelle loro guide indipendenza della posizione dell'angolo di rotazione del cilindro di contropressione corrispondentemente ai valori di acircolaritá misurati e memorizzati in modo che rimanga sostanzialmente costante la loro pressione applicata al cilindro di contropressione.To control the pressure applied by the form-holding cylinders of printing devices of a printing machine, preferably of a flexographic printing machine, to a common counter-pressure cylinder, the form-holding cylinders, supported on slides that can be moved by drives in fixed guides on the frame, they can be approached and removed from this. To ensure a substantially constant applied pressure even in the case where the back pressure cylinder is not perfectly cylindrical, the circularity of the back pressure cylinder, starting from a zero position, is measured according to the rotation angles along its perimeter and the shape-holding cylinders they are moved in their guides independently of the position of the angle of rotation of the back pressure cylinder corresponding to the measured and stored acircularity values so that their pressure applied to the back pressure cylinder remains substantially constant.
