MULTILAYER EXTENSIBLE SLEEVE FOR CYLINDER OF PRINTING MACHINE, PARTICULARLY FOR FLEXOGRAPHIC PRINTING Russian patent published in 2015 - IPC B41N6/00 

FIELD: printing.

SUBSTANCE: invention relates to a multilayer sleeve designed for use on a cylinder of the printing machine, in particular for flexographic printing. The sleeve comprises an inner layer with the inner casing having a hard surface and determining a longitudinal axis and a cavity for mounting on the cylinder, and an outer layer with a cylindrical outer casing, designed in particular to support the outer casing, a printing plate or a separate outer sleeve. The intermediate layer made in the form of lightweight combs with comb cells oriented radially relative to the longitudinal axis, is arranged between the inner casing and the outer casing. The intermediate layer comprises at least one comb layer consisting of cells of the fibre composite cured prior to formation, which is a fibrous material inserted into the matrix from the resin. This intermediate layer itself contributes significantly to the ability of expansion of the inner casing in a radial direction from the longitudinal axis in order to mount the sleeve on the cylinder.

EFFECT: increased efficiency of printing.
