摘要:
A gas collection device of a printing press includes an organic compound treatment system (33) including a gas chamber (34). The device includes a cover (3) configured to cover a print unit (2) of a printing press. The device includes a gas transfer device (4) configured to suck a gas of a volatile organic compound produced in the print unit (2) from the inside of the cover 3 and transfer the gas to the gas chamber (34). It is possible to provide a gas collection device of a printing press, which can prevent a work environment in which the printing press is installed from being deteriorated by the gas of the volatile organic compound.

Umweltfreundliches Reinigungsverfahren, wobei ein zu reinigender Gegenstand in einer Reinigungskammer mit einem Reinigungsmittel, das eine Emulsion enthält, die einen pH von 6 bis 11 und einen Emulgator mit einem HLB Wert von 7 bis 18 aufweist, aus einem Vorratsbehälter gereinigt wird, wobei die verschmutzte Reinigungslösung durch einen Filter, vorzugsweise einem Keramikfilter, gereinigt in den Vorratsbehälter zurückläuft.
摘要:
The present invention is directed to a method for producing a high gloss coating on a printed surface. An aqueous coating composition in pan (1) is deposited onto a surface to be printed using rollers (3, 5) and coating cylinder (9) whose blanket roller coating face has a low energy, non-stick, smooth surface profile on which coating blanket (7) is formed. Simultaneous with the deposition of aqueous coating onto a substrate, or shortly thereafter, pressure between cylinders (9, 10) at nip (11), either alone or in combination with heat may be applied to the coating in order to create a substantially tack-free surface conforming to the surface of the coating face. The substrate is fed to cylinder (10), via cylinder (15) and removed by cylinder (16). By using a highly polished coating face, high gloss coatings may be obtained using this methodlogy in a number of traditional printing techniques including wet trap inline sheet-fed printing, heat-set offset printing, dry trap inline flexographic printing, offset web-fed printing and gravure printing. Coatings which are produced utilizing the present invention have high gloss values heretofore unobtainable using aqueous coating compositions.

Eine Filtervorrichtung ist vorgesehen für den Feuchtmittelkreislauf einer Offset-Druckmaschine, Die Filtervorrichtung ist eine Ringband-Filtereinrichtung, die ein Filterband (28) umfaßt, das entsprechend der Sättigung mit Schmutzpartikeln vorrückbar ist.
摘要:
There is disclosed a cylinder cleaning brush unit (2) including a brush roller (4) for cleaning a cylinder (6). The cylinder (6) includes an outer surface to which impurities are adhered, the impurities being removed from the outer surface by the brush roller (4) with cleaning liquid being supplied. The brush unit comprises an opening (28) through which effluent is discharged from the brush unit, the effluent including the cleaning liquid and the impurities. The brush unit further comprises a filter (30) installed in the opening, the effluent being filtrated by the filter (30).
