Abstract: The invention relates to a machine for chopping organic cut products, especially a meat grinder, comprising an inlet and an outlet for the cut products, at least one perforated disc (1) having a corresponding cutting head (2) and a drive shaft driving the cutting head (2), the cutting head (2) having at least one blade holder (3) with at least one blade (4) that cooperates with the perforated disc (1).

Abstract: In a comminution machine, which is particularly used in industry, with an emulsifier (3), a particularly simple structure with a single driving device for conveying, cutting and emulsifying the material to be chopped is guaranteed when, between a support body (32a) on a stator (32) of the emulsifier (3) and a fulling body (33a) on the corresponding rotor (33), there is a successively narrowing gap (36a) area in which the material to be chopped is exposed to a further constant fulling comminution under pressure. The rotor (33) is rotationally connected with the shaft (4) of the cutting and conveying device of the comminution device. On the rotor (33) a co-axial hub (33c) connected to the fulling body, is provided, with which hub the rotor (33) is fitted on the shaft (4).

Abstract: A flexographic printing machine, especially for flexographic web printing, has at least one printing unit. The printing unit comprises a printing cylinder or an endless printing belt drawn on round a back-up cylinder and a tension roller, an impression cylinder, an engraved roller for transferring the ink to the printing cylinder or to the printing belt, and an ink drier. A paper web runs through all the printing units. Incorporated in each printing unit is a working engraved roller, which can be uncoupled from a drive shaft of the flexographic printing machine during the operation of the latter, and at least one stand-by engraved roller which can be connected automatically in exchange during the set-up time.

Abstract: A flexographic printing machine, especially for flexographic web printing, has at least one printing unit. Such a printing unit comprises an endless printing band drawn on round a back-up cylinder and a tension roller, an impression cylinder, an engraved roller transferring the ink to the printing cylinder or to the printing belt, and an ink drier. A paper web runs through all the printing units.In each printing unit, the bearings of the impression cylinder are fastened rigidly to the machine frame, whereas the bearings of the back-up cylinder and those of the tension roller are arranged displaceably on it, a tension rod keeping a distance (a) between the back-up cylinder and the tension roller constant.
