Abstract

Il pressore secondo il trovato opera sul cilindro di stampa (R) con una robusta membrana (4) in materiale elastomerico, di adatta elasticità e di forma adeguata, saldamente ancorata almeno coi bordi longitudinali a corrispondenti appoggi della barra (1) del pressore. Durante la fase attiva di lavoro del pressore, la membrana viene sottoposta a sollecitazioni composite di compressione, di flessione, di trazione ed altre tali per cui la stessa membrana opera sul cilindro di stampa con una pressione distribuita e tale per cui, al venir meno del contatto col cilindro la membrana medesima ritorna per elasticità propria nella condizione distesa di riposo. In combinazione con l'elasticità della membrana, viene di preferenza sfruttato l'effetto noto della contropressione pneumatica (110) alla quale la membrana stessa viene sottoposta se montata a tenuta stagna su una corrispondente camera (3) di adatto volume della barra del pressore, in seguito al fissaggio a tenuta stagna dell'intero bordo perimetrale della guarnizione sui corrispondenti bordi rialzati di definizione della detta camera.The presser according to the invention operates on the printing cylinder (R) with a robust membrane (4) made of elastomeric material, of suitable elasticity and of suitable shape, firmly anchored at least with the longitudinal edges to corresponding supports of the presser bar (1). During the active working phase of the presser, the membrane is subjected to composite compression, flexion, traction and other stresses such that the same membrane operates on the printing cylinder with a distributed pressure and such that, when the on contact with the cylinder, the membrane itself returns by its elasticity to the relaxed rest condition. In combination with the elasticity of the membrane, the known effect of the pneumatic back pressure (110) to which the membrane is subjected, if mounted tightly on a corresponding chamber (3) of suitable volume of the pressure bar, is preferably exploited. following the watertight fixing of the entire perimeter edge of the gasket on the corresponding raised edges defining the said chamber.
