Abstract: An anilox roller for flexographic printing machines, which comprises a sleeve cylinder rotatably supported about its own axis by the fixed structure of a flexographic printing machine, and an anilox sleeve, which has a tubular body provided, on its outer side wall, with an anilox surface which can be axially fitted on and removed from the sleeve cylinder. Forced circulation of a temperature control fluid within the tubular body is further provided.

Abstract: A machine for printing or spreading primers or coatings and the like with direct and indirect rotogravure system, comprising one or more printing or color units, with a respective drying hood and control unit, each printing or color unit comprising an orientatable inlet roller for tape material, a plurality of free rollers for conveying the tape material, an upper pressure roller, provided with a rubber sleeve, a lower pressure roller, a doctor blade, and an engraved cylinder. At least one roller, chosen between the upper pressure roller and the lower pressure roller, is rotated by a respective step motor and recirculating ballscrews and is supported on linear guides at its ends, with interposed pressure detecting means arranged to forward to the control unit signals indicating the linear pressure between the upper pressure roller and the lower pressure roller and the engraved cylinder.
