| 141 | Covering for sheet-supporting cylinders and drums in rotary offset printing presses | US745696 | 1985-06-17 | US4688784A | 1987-08-25 | Arno Wirz |
| A covering for sheet-supporting cylinders and drums on rotary offset printing machines for printing both on single and both sides of a sheet, the covering having a smooth surface on one side thereof and a textured surface on the opposite side thereof, with sheet-supporting surfaces projecting from the textured surface and formed of hydrophilic and chemically and wear-resistant material includes a device for defining perforations formed in the textured surface, and a device connected to the perforations for selectively applying blowing air and suction therethrough. | ||||||
| 142 | Sheet guide arrangement in sheet-fed machines | US673165 | 1984-11-19 | US4572073A | 1986-02-25 | Rudolf Mitze; Claus Simeth |
| A system for remote sensing, indicating and remote control provides for the non-smear guidance of sheets through a sheet-fed machine and is especially useful for printing machines which print on both sides of the sheets. Sheet guides are adjustable during machine operation from a control panel at a central location outside of the machine. The positions of the sheet guides are preferably displayed in direct comparison with zones of ink application. Also, the sheet guides are adjustable from the control panel so that the guides fall within the gaps between printed areas on the sheet. An immediate and graphic check of the sheet guides is provided. In a preferred embodiment, the positions of the sheet guides are indicated on a linear array of optical indicators, each indicator representing a respective boundary between adjacent inking zones, and two adjacent ones of the optical indicators being simultaneously activated when one of the sheet guides is adjusted approximately at the center of the inking zone defined by the boundaries represented by the two adjacent ones of the optical indicators. | ||||||
| 143 | Smear-free transfer cylinder for sheet-fed rotary printing machines | US637846 | 1984-08-06 | US4552069A | 1985-11-12 | Hans-Georg Jahn |
| Smear-free transfer cylinder for sheet-fed rotary printing machines having a cylindrical casing formed with blow holes distributed over the entire sheet-carrying peripheral surface of the cylinder, includes air distribution elements respectively disposed in the blow holes for influencing blowing air flow out of the blow holes for forming a uniform air cushion, the air distribution elements being formed of air-permeable, elastic and slightly compressible material having a low specific gravity. | ||||||
| 144 | Sheet-guiding foil as a covering for impression cylinders | US141670 | 1980-04-18 | US4327135A | 1982-04-27 | Arno Wirz; Peter Sobotta; Franz Arendt; Otto K. Gramlich |
| A sheet-guiding foil as a sheath for an impression cylinder in rotary offset perfecting presses, one surface of the foil being smooth while the opposite surface thereof is formed with spherical calottes of equal height and of statistically uniform distribution, including a chemically resistant, wear-resistant and rigid backing layer with good ink transfer behavior and a textured surface, and a thin chromium layer applied thereto for evening out microroughness, and the method of production. | ||||||
| 145 | Retractable wheel for paper guiding cylinder | US29611672 | 1972-10-10 | US3780925A | 1973-12-25 | TERNES N |
| The disclosure is directed to a printed paper guiding reel or cylinder having a plurality of small wheel members defining the cylindrical paper engaging surface of the reel. Each of the wheel members is radially retractable to a position of non-engagement to permit selective positioning thereof relative to printed matter which is not yet dried. Retraction of the wheel member is effected by manual movement of the wheel relative to a supporting hub which is retainably disposed in a radial slot in the wheel. The opposite ends of the slot define positions of symmetric and eccentric rotation of the wheel. The slot is narrowed intermediate its ends to force the hub into one stable position or the other, and yielding openings are formed to permit flexure of the wheel in the area of the slot as it is moved between positions.
