摘要:
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.

Techniques are disclosed for connecting a printing plate to a print cylinder or surface. The techniques may be implemented, for instance, with respect to a printing plate, a print cylinder, a print sleeve, or some combination thereof. In an embodiment, a field of mechanical fasteners is provisioned on a printing plate, and a complementary field of mechanical fasteners is provisioned on a print sleeve or cylinder. The mechanical fasteners collectively operate to provide a mechanical bond or interface that inhibits lateral and rotational movement of the plate during printing operations, and can also be configured to manage backlash between engaging surfaces of the interface. In some cases, backlash management includes use of cushion effect integral with the mechanical bond itself and/or unidirectional and possibly angled fastener elements to provide a snugging effect. The mechanical bond may be implemented with hook-and-loop, hook-and-hook, hook-to-channel, male/female-type fittings, vacuum, suction, and/or magnetics.

An automatic handling and transport device for printing sleeves that includes a holding support (10) for printing sleeves (60) and a clamping carriage (20) connected to a motorized carriage (30) for a guided movement of the clamping carriage (20) between a gripping position for gripping sleeves (60) and a transport position, and a mobile handling unit (90) carrying the holding support (10). The holding support (10) has an inner core (12) attached to the mobile handling unit (90), and the holding support (10) is coupled to the core (12) or to the mobile handling unit (90) through adaptable support means (40), which provide a relative movement with respect to the core (12) to at least one of the two ends of the holding support (10). The connection of the clamping carriage (20) to the motorized carriage (30) comprises adaptable means (49) that allow a relative movement between the clamping carriage (20) and the motorized carriage (30).

A removable flexible jacket for use in a printing press having a transfer cylinder for transferring a freshly printed substrate comprises a sheet of woven fabric, a beaded film sheet coupled to the sheet of woven fabric, and an image disposed between the sheet of woven fabric and the beaded film sheet. The image is visible through the beaded film sheet, and wherein the image divides at least a portion of a surface of the beaded film sheet into a plurality of zones.
摘要:
A printing group of a rotary printing press includes at least one forme cylinder and at least one transfer cylinder. The forme cylinder has at least two printing forme end receiving channels. These two channels are spaced circumferentially. At least one of these forme cylinder end receiving channels rolls off against a channel in the transfer cylinder. One of the forme cylinder end receiving channels is at least partially covered by a printing forme carried by the forme cylinder.

A printing press includes a combination printing blanket and blanket cylinder having a fill-in bar adapted to receive both ends of the printing blanket. The printing blanket and the fill-in bar are preattached, and, after wrapping the blanket around the cylinder, a barbed snap fit is achieved to fastened the blanket tightly around the cylinder.
摘要:
A packing is secured to a cylinder of a rotary printing machine. The ends of the packing have suspension strips that are placed in a cylinder channel. A tightening strip is movable radially in the cylinder channel. One suspension strip is held, by one side of the tightening strip, in a channel groove in the cylinder channel. The other suspension strip is movable radially in the cylinder channel by radial movement of the tightening strip.

A blanket cylinder (10) having an inner mandrel (12) having an outer surface (14), a split shell (16) having a longitudinal slit (18) defining opposed ends (20 and 22) of the shell (16), and being positioned on the outer surface of the mandrel (12) with a minimal gap (24) between the opposed ends (20 and 22) of the shell (16), a device for retaining the shell (16) on the mandrel (12), and a compressible blanket (34) being formed on an outer surface (36) of the shell (36) and having dimensions to close the opposed ends (20 and 22) of the shell (16).
摘要:
An offset blanket for a grooveless blanket cylinder for applying a printed image onto web material or sheet material is composed of a carrier plate which has been cut to size and a rubber layer placed on the carrier plate. The beginning and the end of the carrier plate of the rubber layer are connected to each other so that the outer circumferential surface of the blanket is continuous and without gaps. The blanket surrounds the blanket cylinder in the operating position in the form of a sleeve in a frictionally engaging manner but releasably. A register device is provided on at least one end face of the blanket for securely positioning the blanket on the blanket cylinder.

An apparatus for stretching a cylinder blanket on a sheet transfer cylinder of a sheet-fed printing press includes a tiltable member mounted on the cylinder. A first end of the blanket is first attached to the cylinder in a cylinder groove, the blanket is wrapped around the cylinder, and the second end of the blanket is attached to the tiltable member, while the tiltable member is in an open position. The tiltable member is then closed to stretch the blanket about the cylinder, and locked into the closed position to maintain the blanket about the cylinder.
