Abstract: An apparatus and method for printing multi-color images onto a cylindrical body includes ink adhesion mechanisms that adhere different colors of ink to an outer peripheral surface of the cylindrical body. Ink drying mechanisms are included for drying the different colored inks adhered to the cylindrical body after the completion of the respective ink adhesion processes. Each of the ink adhesion mechanisms is arranged such that a mandrel, about which the cylindrical body is held, is moved in an arc along the outer periphery of a cylinder-shaped blanket which is disposed around the outer peripheral surface of an blanket cylinder. Ink is applied to the cylindrical body from the blanket at a position where the cylindrical body contacts the blanket. The blanket cylinder is rotated about an axis thereof in the direction opposite to the moving direction of the mandrel. The mandrel is rotated about an axis thereof so that a relative velocity of the cylindrical body and the blanket at the contact portion is zero.

Abstract: The invention relates to an impression cylinder (1) intended for a sheet-fed machine and having at least one cylinder gap (3) in which sheet grippers (4) are arranged in such a manner that, when closed, they do not project over the envelope of the peripheral area of the impression cylinder (1). The cylinder gap (3) is provided with a cover (7) which can be adjusted by a controlling unit (9, 10, 11, 12) and is subsequently always in its closed position in which it completely covers the cylinder gap (3), when said gap (3) passes through the nip. Consequently, the impression cylinder rolls with a continuous, closed peripheral area on the cylinder printing the image. In the zones where the sheet is transferred to and from the impression cylinder (1), the cover (7) (preferably controlled by a fixed cam (11) while the cylinder is rotating) is opened to such an extent that the sheet grippers (4) can move into the open position thereof to pick up or release a sheet.

Abstract: A leading edge side shaft 6, a tail edge side shaft 12 and a pulling shaft 14 are interlocked with one another through gears. The gears are rotated by using rotation of the plate cylinder. A leading edge side part 10a of the plate 10 is clamped with a leading edge side clamp 4 in accordance with the rotation of the leading edge side shaft 6. Thereafter, a tail edge side part 10b of the plate 10 disposed on the cylinder surface of the plate cylinder 60 is clamped with a tail edge side clamp 5. The plate 10 is pulled in a plate tensioning direction as a result of moving the tail edge side clamp 5 in the direction of the arrow 90 in accordance with the rotation of the pulling shaft 14.

Abstract: There is disclosed an ink roller assembly and a method of making an ink roller assembly. The assembly includes a base comprised of closely spaced connected discs providing capillary chambers and a porous sleeve. The method uses air under pressure or vacuum to expand the porous sleeve while the sleeve is being slipped onto the base. The sleeve has an internal diameter less than the external diameter of the base.

Abstract: A retrofitting, folding, portable keyboard for a notebook computer consists of two, pivotally-hinged halves. The two halves are hinged so that may be assume a perfectly flat, horizontal position, or, alternatively, a laterally raised and sloping configuration that provides an enhanced, ergonometric configuration to the user. Each half has its own set of keys and space bar. The keyboard of the invention has its own pointing device that takes over the pointing function of the pointing device of the dedicated keyboard provided with the notebook computer. The portable, folding keyboard of the invention also has a joystick-adapter by which a conventional joystick may be operatively coupled to the notebook computer by which games may be played. Four, bottom, pivotal feet support the keyboard on and/or above the existing keyboard provided with the notebook computer. A carrying case is provided in which the folded-up keyboard may be stored and transported.

Abstract: A tape dispenser is capable of printing patterns and words on the tape dispensed thereby and is composed of a main body, a tape roll holding portion mounted on the main body, a printing wheel fastened pivotally with the main body, an ink supplying device fastened with the main body such that the ink supplying device is capable of inking a printing plate of the printing wheel, and a tape cutter for severing the tape.

Abstract: A dry cleaning system for removing dust and lint on the fly from blanket cylinders in offset printing presses. The cleaning system includes a relatively small brush mounted for rotation about an axis substantially perpendicular to the rotational axis of the blanket cylinder. In operation, the brush can be reciprocally moved across the surface of the blanket cylinder and selectively moved into and out of contact with the blanket cylinder. The contact pressure of the brush is pneumatically controlled to maintain a predetermined, set pressure and the brush automatically retracts should the pressure source fail. The system can be operated to clean the entire width of the blanket cylinder or only the portion of it actually being used to print. A vacuum pickup is included with its separately mounted housing and the entire cleaning system is carried on a unitary support structure that is removably secured at its ends for quick and easy installation and removal.

Abstract: A cam shaft 23 is rotated 90 degrees when the plate 10 is fitted on the plate cylinder 60. Thus, as a result of the rotation, a flange part 3T of the tail edge side clamping base 3 is pushed by movement of a spring base 15 which receives a pushing force generated by springs 16. Therefore, the plate 10 is pulled in a tension applying direction. Since the tail edge side clamping base 3 does not receive the limitation of the cam shaft 23 directly, the tail edge side clamping base 3 can be moved in a direction parallel to a shaft of the plate cylinder 60. Thus, a diagonal image adjustment of the plate can be done easily.

Abstract: A keyboard assembly comprises at least one key unit including a plurality of keys each having a front end and a base end, a common key support supporting the keys, and a connecting portion provided on the base end of each of the keys and connecting between each of the keys and the common key support. The keys are formed integrally with the connecting portion and the common key support in a manner such that the keys are each connected via the connecting portion to the common key support for swinging about the common key support in a direction of depression and release of the keys and in a direction in which the keys are juxtaposed. The keys define gaps therebetween, each of which becomes progressively larger toward the front end of an associated one of the keys.

Abstract: In a stencil sheet clamping construction for clamping a leading end portion of a stencil sheet to a stencil printing drum, a press plate is set at a half open position making an acute angle against an upper surface of a base portion when the leading end portion of the stencil sheet is mounted. This allows the leading end portion of the stencil sheet to be lifted above the upper surface of the base portion by floating up of an elastic film belt when the stencil sheet is discharged. This also prevents obstruction of the smooth advance of the leading end portion of the stencil when it is mounted due to the floating up of the elastic film belt.

Abstract: The invention provides an ink ribbon cartridge which ensures proper, reliable mounting of an ink ribbon. The ink ribbon cartridge of the invention includes a pair of spools, an ink ribbon including a band-like sheet wound around the pair of spools and provided with a layer of ink formed on one surface thereof, four spindles which have disk-shaped sections at one end and can be placed, for a specific length in both ends of the pair of spools, and a cover covering the pair of spools around which the sheet is wound and having four round holes in which the disk-shaped sections of each of the spindles are loosely fitted. In one of the four ends of the pair of spools, only the other end of a specific one of the four spindles can be inserted for a specific length, and one of the four round holes formed in the cover is formed such that only the disk-shaped section on one side of the specific spindle can be loosely fitted.
