An apparatus for printing a beer barrel includes a workbench, and a hydraulic pushing device, a barrel outer-sided printing device, and a barrel inner-sided printing device installed on the workbench. The barrel inner-sided printing device has a turntable rotating with respect to the Z-axis and mounted on the barrel, an inner mold installed onto a circumferential surface of the turntable for printing the inner side of the barrel. The barrel outer-sided printing device has a connecting frame moving linearly along the Y-axis direction. The connecting frame has an outer mold for printing an outer side of the barrel, and the hydraulic pushing device controls the outer mold to move linearly along the X-axis direction. The outer and inner molds print a sidewall of the barrel. This invention prevents unnecessary waste of manufacturing cost and time caused by the scrap of semi-finished products whose previous printing process becomes useless.

The present invention relates to a device for printing on hollow bodies and comprising a segmented wheel and a system for sequentially supplying the hollow bodes to the periphery of the segmented wheel. That system includes at least one conveyor wheel and one mandrel wheel, First, the conveyor wheel, then the mandrel wheel, and then the segmented wheel are arranged in the transport direction of the hollow bodies. A plurality of driving elements are arranged on the periphery of the conveyor wheel, and a plurality of holding elements are arranged on the periphery of the mandrel wheel. Each holding element receives a respective hollow body to be printed in cooperation with the segmented wheel. The mandrel wheel and the conveying wheel each have their own drive, each of which drive is separate from a drive of the segmented wheel.

A turret styled container decorator machine is disclosed having a rotatable turret and a number of circumferentially spaced container holding assemblies for holding a variety of pieces of media, such as a drink container, the surface of which is to be printed upon with an image. A plurality of workstations are positioned around the perimeter of the turret through which each media holder passes as the turret rotates. Each workstation includes an ink printing assembly and a curing assembly so that ink may be applied and cured as each piece of media is indexed into each workstation location. Each printing workstation may be removed and replaced with a different arrangement or configuration of ink heads to suit different types of media sizes and shapes, and the turret holds a plurality of media holding means assigned to a pie-shaped section of the turret adjustable to accommodate various types of media geometries.

A processing machine for processing sheets comprises at least one application unit and at least one sheet sensor associated with that application unit. The at least one sheet sensor is arranged upstream of the associated application unit, along a transport path for sheets. The at least one sheet sensor is configured to detect the arrival time of sheets as the position of the sheet sensor. The at least one application unit, in each case, comprises at least one printing couple having a forme cylinder and an individual drive which is associated to that forme cylinder. The at least one sheet sensor is configured to control the position or the rotational speed of the forme cylinder in one of a closed loop or an open loop. The invention also relates to a method for processing sheets.

A method for operating a device for printing hollow cylinder is provided. The device comprises a rotating segmented wheel with a plurality of printing cylinders arranged successively along the periphery of the device. A plurality of plate cylinders are provided in association with the segmented wheel. According to a printing process to be performed, a selected quantity of plate cylinders is thrown onto the segment wheel or is thrown off the segment wheel. In a first printing process, a first partial quantity of thrown-on plate cylinders transfers printing ink to a plurality of the printing blankets arranged on the segment wheel. At the end of the printing process, at least some of the plate cylinders, that were thrown on the segment wheel in the first printing process, are thrown off the rotating segment wheel. During constant uninterrupted rotation of the segment wheel, for the implementation of a second printing process, a second partial quantity of plate cylinders is thrown onto the segment wheel and respectively transfer printing ink to a plurality of the printing blankets arranged on the segment wheel. The respective printing forme of at least one plate cylinder involved in the first printing process, and uninvolved in the ongoing second printing process, is changed during the ongoing printing process.

A system and method for the overprint on flexible supports are described. In particular, the overprint system 1 comprises a printing unit 2 comprising a rotatable printing cylinder 3, having printing zones at the surface thereof, and first actuating means 14, configured to drive in a controllable manner the printing cylinder 3 rotation. The system further comprises a first reel 5 for unwinding a flexible support 4 to be printed, which has preset zones to be overprinted, and a second reel 8 for rewinding the flexible support 4, once it has been printed. A plurality of winding rolls 7 arranges an unwinding path, for the flexible support 4, comprised between the first 5 and the second 8 reels, and passing through the printing unit 2. The system then comprises second actuation means 20, configured to drive in a controllable manner the flexible support 4 advancement along the unwinding path (upstream of the printing unit 2 in the unwinding direction), and control means 10, configured to control in a coordinated manner both the first actuating means 14 and the second actuation means 20, so as to determine at every moment a correspondence of the preset zones to be overprinted of the flexible support 4 with respective printing zones of the printing cylinder 3.

A system prints solid ink images on fibrous objects. The controller of the system is configured to operate a first motor to move an object rotating subsystem to and from a position opposite a plurality of printheads, to operate a second motor to rotate an object on a spindle of the object rotating subsystem at the position opposite the plurality of printheads, to operate a forced air heater to direct heated air onto a surface of the object as the object rotates at the position opposite the plurality of printheads, and to operate the plurality of printheads to eject a solid ink marking material onto the heated surface of the object as the object rotates in the first and/or second rotational direction. The solid ink image is affixed to the object by the heating of the object surface alone.

A method is provided for printing on hollow bodies in which the hollow bodies are printed on in a decorator having a rotating segment wheel. Printing ink provided by multiple different plate cylinders and inking units are each collected on printing blankets arranged one after another on the circumference of the segment wheel. The plate cylinders and inking units involved in the printing are arranged and set in such a way that, when printing on the hollow body, an iris print is, or at least can be implemented.
