A plate sleeve-holder cylinder provided with a carbon-fibre central tube (T) comprising compressed air channels (6, 7, 8) arranged between one of the end flanges (Fb, Fm) of said plate sleeve-holder cylinder and a plurality of holes (H) formed in the outer surface of said central tube (T) made of carbon-fibre composite material. Said air channels (6, 7, 8) are partly embedded within said end flanges (Fb, Fm), partly within a thickness of a side wall (P) of said central tube (T) made of carbon-fibre composite material. Additionally, a process of manufacturing said central tube (t) is disclosed by inserting air pipes (6) into grooves (1) which are formed by mechanical milling of a surface of the supporting structure (P) of said central tube (T) obtained through a first lamination and polymerization, said grooves being coated with a surface finishing structure (S) obtained through a second lamination and polymerization.

A printing assembly may include a first continuous cylinder and a first jogging assembly. The first continuous cylinder may be configured to apply print media to a flexible substrate responsive to contact with the flexible substrate. The first continuous cylinder may include a plurality of partitions configured such that only one of the partitions is aligned for contact with the flexible substrate at any given time, and each of the partitions may have a unique print characteristic associated therewith. The first jogging assembly may be operably coupled with the first continuous cylinder to move the first continuous cylinder along an axis thereof to change alignment of the partitions relative to the flexible substrate.

A device for producing a pattern combination on a clothing includes the following: a rotary screen, a cylindrical jacket surface with a perforation pattern that defines a first pattern component. Material in the liquid or pasty state is pressed through the perforations of the jacket surface of the rotary screen and deposited on the surface of the clothing in order to produce the first pattern component on a surface of the clothing, while the rotary screen, rotating several times about a longitudinal axis thereof, rolls on the surface of the clothing in at least one path that continuously revolves on the surface of the clothing at least once. At least one device produces, synchronously and/or simultaneously, a second pattern component, which device is connected indirectly or directly to the rotary screen. The device for producing the pattern combination also includes a post-run system.

A method for assembling a hollow cylinder on, or removing a hollow cylinder from, a further cylinder. The hollow cylinder includes a body with openings for creating an air cushion within a first portion of a shell and a second portion of the shell is gas-impervious or has openings for creating an air cushion of a reduced quantity and/or size compared to the first portion. The openings are connected to a gas feed and a gas inlet inside the body. The further cylinder has openings on a shell and gas is fed though the openings via an internal gas supply. An assembly method includes providing the hollow cylinder, applying a seal to the first portion to prevent escape of gas from the first portion, providing the further cylinder, applying gas to the further cylinder so that gas escapes from the openings, and pushing the hollow cylinder onto the further cylinder.
