LASTRA DA VERNICIATURA REVERSIBILE REVERSIBLE PAINTING PLATE
La presente invenzione riguarda una lastra da verniciatura, ed in particolare una lastra da verniciatura reversibile, nota anche con il nome di caucciù da verniciatura, che può essere impiegato nelle macchine da stampa per verniciature offset. The present invention relates to a coating plate, and in particular a reversible coating plate, also known by the name of coating blanket, which can be used in printing machines for offset coating.
US 6205922 descrive un telo da stampa, quindi non una lastra da verniciatura, reversibile comprendente almeno uno strato di supporto disposto tra due superfici da stampa, in cui uno o più strati polimerici sono saldamente uniti tra lo strato di supporto e le superfici da stampa. US 6205922 discloses a printing cloth, therefore not a coating plate, reversible comprising at least one support layer arranged between two printing surfaces, in which one or more polymeric layers are firmly joined between the support layer and the printing surfaces.
Le superfici da stampa e/o gli strati polimerici presentano caratteristiche fisiche e/o chimiche diverse, in modo che con lo stesso telo sia possibile eseguire due differenti processi di stampa semplicemente capovolgendo il telo da stampa. The printing surfaces and / or the polymeric layers have different physical and / or chemical characteristics, so that with the same sheet it is possible to perform two different printing processes simply by turning the printing sheet upside down.
Scopo della presente invenzione à ̈ quello di fornire una lastra da verniciatura che può essere impiegata per più di due differenti processi di verniciatura. Detto scopo viene conseguito con una lastra da verniciatura le cui caratteristiche principali sono specificate nella prima rivendicazione, mentre altre caratteristiche sono specificate nelle restanti rivendicazioni. The purpose of the present invention is to provide a painting plate which can be used for more than two different painting processes. Said object is achieved with a painting plate whose main characteristics are specified in the first claim, while other characteristics are specified in the remaining claims.
Grazie ad un adesivo removibile sulle superfici dello strato di supporto, entrambe le superfici da verniciatura della lastra da verniciatura secondo la presente invenzione possono essere staccate parzialmente dallo strato di supporto, in modo che possono essere impiegate una superficie da verniciatura o la superficie opposta girando la lastra da verniciatura. Thanks to a removable adhesive on the surfaces of the backing layer, both painting surfaces of the painting plate according to the present invention can be partially detached from the backing layer, so that one painting surface or the opposite surface can be used by turning the painting plate.
Differenti configurazioni della lastra da verniciatura possono essere ottenute impiegando strati polimerici che consentono una rimozione più facile di una superficie da verniciatura dallo strato di supporto e/o strati comprimibili che consentono di assorbire eventuali differenze di spessore o irregolarità del supporto da verniciare e/o strati stabilizzanti che riducono i movimenti nelle direzioni parallele alla superficie da verniciatura. Different configurations of the painting plate can be obtained by using polymeric layers that allow easier removal of a painting surface from the support layer and / or compressible layers that allow to absorb any differences in thickness or irregularity of the support to be painted and / or layers stabilizers that reduce movements in directions parallel to the surface to be painted.
Ulteriori vantaggi e caratteristiche della lastra da verniciatura secondo la presente invenzione risulteranno evidenti agli esperti del ramo dalla seguente descrizione dettagliata e non limitativa di sette sue forme realizzative con riferimento agli annessi disegni in cui: Further advantages and characteristics of the painting plate according to the present invention will become evident to those skilled in the art from the following detailed and non-limiting description of seven of its embodiments with reference to the attached drawings in which:
