Abstract
A stripper for a printing machine cleaning device includes a shaped pressure hose, which is disposed parallel to the roller of the printing machine that is to be cleaned. The cross-sectional shape of the hose can be varied by being pressurized. The surface of the pressure hose remote from the roller is secured on a rigid rail, while the surface of the pressure hose remote from the rail can be pressed, as a result of pressurization of the hose, against the roller.
Claims15
In combination with a printing machine having a roller (2, 8), the surface of which is to be cleaned or stripped,
- a stripping device for cleaning said roller (2, 8)
- comprising, in accordance with the invention,
- a support rail (5, 7) extending axially parallel to the roller (2, 8) to be cleaned;
- and a pressure hose (1, 6) secured to the rail with a surface thereof remote from the roller (2, 8) and extending axially along the roller, the pressure hose being expandable in cross section upon pressurization with a pressure fluid, and thereby engageable with the facing surface of the roller at a pressure which is essentially uniform over the axial length of the roller.
In combination with a printing machine having a roller 82, 8), the surface of which tends to accumulate ink, which ink is to be cleaned or stripped off said surface,
- an ink cleaning or stripping device for cleaning the surface of said roller (2, 8) and stripping ink accumulated on said surface from said roller,
- comprising, in accordance with the invention,
- a support rail (5, 7) extending axially parallel to the roller (2, 8) to be cleaned;
- a pressure hose (1, 6) secured to the rail with a surface thereof remote from the roller (2, 8) and extending axially along the roller, the pressure hose being expandable in cross section upon pressurization with a pressure fluid, and thereby engageable with the facing surface of the roller at a pressure which is essentially uniform over the axial length of the roller.
