Device for moving paper reels in an unwinder of the type in which a nearly empty reel () is moved along a predetermined path between more operating stations in each of which the reel () is free to rotate about its longitudinal axis. The device is disposed and acting between the said operating stations and comprises: a carriage () intended to support a nearly empty reel () and movable between said operating stations, the reel () being free to rotate about its longitudinal axis on the carriage (); a structure () supporting said carriage (); means for moving said carriage () between said operating stations; means for controlling said means for moving the carriage ().

Device and method for moving reels in an unwinder

Device for the substitution of a clich&#xe9;-jacket from a clich&#xe9; cylinder in a printing machine or the like wherein said cylinder () is connected to a motor () driving it into rotation about its longitudinal axis and is provided with radial holes connected with an air inlet (), the latter being apt to be connected with a compressed air supply () by means of a delivery means (), device characterized in that it comprises automatic means sensing the position of said air inlet () relative to said delivery means () and automatic means for positioning said air inlet () and said delivery means in a reciprocal coupling position, said automatic sensing and positioning means being connected to a programmable electronic unit (E) which, when said air inlet () and said delivery means () are coaxial, drives said coupling and switches on an on-off valve () which, on a side, is connected to said compressed air supply () and, on the other side, is connected to said delivery means ().

Device and method for removing the jacket from clich&#xe9; rollers in printing machines

A distributor unit includes a reservoir () containing a liquid substance, an anilox cylinder () and a clich&#xe9; cylinder () onto which is movably fitted a cliche jacket (), the reservoir (), the anilox cylinder () and the cliche cylinder () being movable from and to a cylinder () on which travels a web-shaped material () which has to receive the substance. The distributor unit has an operator side and a transmission side, the anilox cylinder () and the cliche cylinder () being held by corresponding supports on operator side () and on transmission side (). A device () for locking the cliche cylinder in cantilever position when the corresponding cliche jacket () has to be substituted is associated to the support on transmission side () of the cliche cylinder (). The support on operator side (); of the cliche cylinder () includes a first and a second element () automatically movable from and to the cliche cylinder (). The elements in configuration of use hold the cylinder () on the operator side and, in a configuration of substitution of the cliche jacket (), are reciprocally spaced disengaging the operator side of the cliche cylinder ().

Distributor unit for liquid substances

Device for cleaning rolls in printing machines, specially machines for executing prints on web-shaped paper-like material destined to the production of tissue paper, napkins, toilet paper and the like, characterized by the fact that it comprises: a nozzle () apt to direct a steam jet toward the surface of a roll () to be cleaned: said nozzle () being connected to steam feeding means; a suction chamber () within which is disposed said nozzle () and apt to execute an aspiration in correspondence of the surface of the roll () interested by the steam et supplied by the nozzle (): said chamber () being connected to relevant suction means; a plurality of holes () oriented toward the surface of the roll () to be cleaned, and connected to air compressed feeding means.
