Abstract: An apparatus (1) for preparing a flexographic printing sleeve (3) comprises a support structure (21), comprising first support mechanism (2) which defines a workstation for rotatably supporting a first flexographic printing sleeve (3) such that it can rotate about a preset axis (K-K), a roll (11) of double-sided adhesive tape rotatably supported by a second support mechanism (10), and a first feeding and guiding mechanism (13) for unwinding the double-sided adhesive tape (12) from the roll (11) and directing the double-sided adhesive tape (12) to the surface of the first sleeve (3).

Abstract: The present invention concerns a viscous damping device for reducing the rotation speed of the winding roller of a screen once the screen has been previously unrolled from the roller against an energy storing device, which causes the rotation of the roller as the screen is being rewound. According to the invention, the device has a shaft, with a first end having means for axial coupling thereof to the screen winding roller, a rotor, coaxially placed on said shaft, a box-like element enclosing said rotor, as well as means for connecting said shaft to said rotor as the roller rotates and the screen is rewound and for disconnecting said shaft from said rotor as the screen is unwound from the roller.

Abstract: A book (100) includes a front cover (A), a back cover (B) and a plurality of intermediate sheets (1-11) disposed between the front cover (A) and the back cover (B) so as to define a plurality of printed pages (P1-P12), the covers (A, B) and the intermediate sheets (1-11) being bound, by means of a binder (20), on the left-hand edge of the book. A printed circuit board (30) with a plurality of LEDs (L1-L8) is disposed in the back cover (B), and slots (S) in the back cover (B) make the LEDs (L1-L8) visible. Through holes (F) are made in at least some of the intermediate sheets (2-11) to make visible the respective LED coinciding with the through hole (F). A magnetic page identifier (40) for identifying the pages that are being read is also disclosed.
