Printing system and printing kit for fixation to flexographic printing cylinder

FIELD: printing industry.

SUBSTANCE: inventive printing system for fixation to a flexographic printing cylinder or sleeve located on a flexographic printing cylinder comprises a continuous first anti-adhesive backing and a self-adhesive damping layer to attach the printing system to a cylinder or sleeve. The self-adhesive damping layer is attached to the continuous first anti-adhesive backing and consists of at least two separate parts with different Shore hardness according to the A scale. In addition, a printing kit is provided for fixation to a flexographic printing cylinder or a sleeve located on a flexographic printing cylinder, including the system and printing form.

EFFECT: printing system has a high adhesion quality for fixation to a cylinder or sleeve and is configured to reuse the printing form in the event of inadequate attachment of the printing system to the cylinder or sleeve.

FIELD: printing.

SUBSTANCE: invention relates to the field of printing. The stated device comprises several spaced at a distance (a, b) from each other storage panels (22; 23; 24). In the appropriate storage panel (22, 23, 24) at least one printing plate (08) is located or, at least, is adapted to be placed, which is taken from the plate cylinder (01) of the rotary printing machine, or the printing plate (08) placed on the plate cylinder (01). And, at least one control unit (31) is provided. The control unit (31) is arranged to install at least one end area facing towards the plate cylinder (01) of at least two of the storage sections (22, 23, 24) in their respective operating position delivered to the plate cylinder (01) at different times in the same position relative to the plate cylinder (01).

EFFECT: invention enables to improve convenience of delivering the printing plate to the plate cylinder.

SUBSTANCE: invention relates to device for accumulating tympans to be delivered to impression cylinder in which several tympans designed for installing close to one another on cylinder in its axial direction are kept near each other. Said tympans designed for installing close to one another are kept vertically under backing in at least two planes vertically displaced relative to each other. Planes displaced relative to each other form first accumulating position for tympans, and backing, after placing of at least one of tympans kept in displaced planes onto said backing, forms second accumulating position.

EFFECT: possibility of quick and reliable replacement of several tympans on cylinder of printing machine either simultaneously or quickly in sequence.

FIELD: engineering of devices for accumulation of blankets, meant for feeding to cylinder of printing machine, and also technology for feeding blankets onto cylinder of printing machine.

SUBSTANCE: device for accumulation of blankets has holder, which in first working position holds blanket in first accumulating position, while blanket during transition of holder to second working position it freed from holder and leaves its first accumulating position. Below first accumulating position at a certain distance from it along vertical line second accumulating position is provided, in which prior to its feeding onto cylinder, blanket released by holder is positioned. Method for feeding blankets onto cylinder of printing machine includes placing blankets meant for feeding onto cylinder into accumulator for their length without mutual contact. Blankets meant for serial feeding onto cylinder are placed along their length one above another in accumulation positions, distanced from one another for certain distance along vertical line. Method also takes into consideration, that at least one blanket is fed onto cylinder only after its displacement from its vertically higher accumulating position to its vertically lower accumulating position.

EFFECT: possible fast and reliable replacement of several blankets simultaneously or one by one on the cylinder in printing machine.

SUBSTANCE: group of inventions relates to the design of an adhesive tape which improves adhesion by eliminating air bubbles between the adhesive tape and the substrate, to an anti-adhesion liner and to a method for creating a groove on the surface of the adhesive film. Adhesive tape comprises at least one adhesive layer, wherein the adhesive layer has at least one groove, and not one grooves reaches one of lateral edges of the adhesive layer. Anti-adhesion liner is provided with a surface having at least one rib, and not one rib reaches one of the lateral edges of the anti-adhesion liner. Method of creating a groove on the surface of the adhesive film involves an operation of contacting the surface of the material with one rib with the surface of the adhesive layer to create a groove.

EFFECT: technical result achieved with the use of the group of inventions is to counteract the displacement of air bubbles within the adhesive tape when pressure is applied.
