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). According to the invention, the intermediate layer (120) comprises 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 shaped coaxially around the longitudinal axis (A). |
