Abstract

A sleeve (10) for mounting on a mandrel of a commercial printing machine can include distinct annular regions that are integrally formed simultaneously as a unitary structure without a forming mandrel and without any need to be adhered to one another in manufacturing steps separate from the manufacture of each annular region of the completed sleeve. A 3D printing machine and method suitable for one or more of the flexible packaging industry, the offset printing industry, the publication printing industry, the decor printing industry, and the corrugated printing industry, employs a build plate that descends from a horizontal printing plane where each of multiple printing heads extrudes a road cycle of thermoplastic material onto the immediately underlying road cycle of the sleeve.

Abstract

An adapter sleeve has an external layer for supporting a printing cylinder carrying data and/or images to be printed. The adapter sleeve has an internal layer defining a bore enabling the sleeve to be mounted onto a rotary mandrel of a printing machine. Each opposite extreme end of the adapter sleeve includes a rigid, load-bearing, radial spacer member disposed between the layers to provide rigidity and indeformability during the use of the sleeve with time. The inner surface of each of the extreme end radial spacer members is defined by rigid and non-deformable material of very low coefficients of dynamic and static friction.

Abstract

Flexographic printing machine comprising a central drum (1 ) rotating about its own longitudinal axis serving as a support for an element to be printed and a plurality of printing elements (2) arranged around said drum (1 ) as satellites, each comprising an inking or anilox roller (5) and a rotating roller or bridge-plate sleeve (7) to which said roller transfers the ink, by contact, said bridge-plate sleeve (7) carrying print characters and transferring them to the element to be printed placed between the sleeve and the central drum. The machine comprises a cleaning device (1 1 ) with a plurality of cleaning rollers capable of replacing corresponding bridge-plate sleeves so as to clean, by means of a cleaning organ supported by them and by means of rotation and translation of said rollers about and along their own longitudinal axis, the ink present on the surface (20) of the drum (1 ). A method and device for cleaning said drum is also claimed.

Abstract

A bridge sleeve has at each extreme end of the bridge sleeve, a multi-component stabilizer. One component of each stabilizer includes an inner cylindrical contacting surface having a diameter that changes as this respective component of the stabilizer moves axially relative to at least one other component of the respective stabilizer.
