Abstract: The invention relates to a multi-layer, expandable sleeve (100) for a printing press cylinder and to a method of manufacturing this expandable sleeve. The sleeve has an inner layer (110) with a hard surface inner jacket (112), which defines a longitudinal axis (A) and the cavity for mounting on the cylinder, and an outer layer (130) with a cylindrical outer jacket (132) for carrying an outer shell, a printing plate or a separate outer sleeve, in particular. An intermediate layer (120), manufactured in the form of a lightweight honeycomb having honeycomb cells oriented radially (B) to the longitudinal axis (A), is provided between the inner jacket (112) and the outer jacket (132). The intermediate layer (120) includes at least one honeycomb layer (122-1, 122-2, 122-3, 122-4, 122-5) of fibre composite honeycomb consisting of fibre material embedded in a resin matrix that has been applied coaxially around the longitudinal axis (A).

Abstract: The invention relates to a method for the production of a fiber reinforced sandwich component (10) having a honeycomb core (12), the honeycombs of which are closed on both sides. The honeycomb core is closed at least on one side by a cover layer (14) made of fiber material, which is embedded in matrix material. The method comprises the following steps: —Producing a fabric comprising the honeycomb core and at least on one side of the honeycomb core, disposed from the inside to the outside, a curable adhesive layer (20), a barrier layer (16) and a fiber layer (14); —Locking the fabric on a one-sided molding tool (30) in a gastight chamber, which is formed up by a vacuum foil (48) on the one-sided molding tool; —Creating a vacuum in this gastight chamber, —After creating the vacuum, hardening or partial hardening of the adhesive layer between the honeycomb core and barrier layer in this vacuum such that the honeycomb cells (18) are evacuated at least partially before they are closed off by the barrier layer; —After hardening or partially hardening of the adhesive layer, infusion of the fiber layer in a vacuum with a matrix material; and —Hardening of the matrix material in a vacuum.

Abstract: The invention relates to a multi-layer, expandable sleeve (100) for a printing press cylinder, particularly for flexographic printing. The sleeve has an inner layer (110) with a hard surface inner jacket (112), which defines a longitudinal axis (A) and the cavity for mounting on the cylinder, and an outer layer (130) with a cylindrical outer jacket (132) for carrying an outer shell, a printing plate or a separate outer sleeve, in particular. An intermediate layer (120), manufactured in the form of a lightweight honeycomb having honeycomb cells oriented radially (B) to the longitudinal axis (A), is provided between the inner jacket (112) and the outer jacket (132). According to the invention, the intermediate layer (120) comprises at least one honeycomb layer (122-1, 122-2, 122-3, 122-4, 122-5) consisting of shaped cured fiber composite honeycomb made of fiber material embedded in a resin matrix. This intermediate layer (120) in itself makes the essential contribution to the inner jacket (112) being able to expand radially away from the longitudinal axis (A) for mounting the sleeve (100) on the cylinder.
