Abstract
The side wall (5) for an ink fountain of a printing machine has two plates (11, 14) fixed some distance apart and an intermediate plate (13) having a front edge (13a) in the shape of an arc of a circle. This intermediate plate (3) is mounted between the plates in such a way that it can be shifted and tilted. The front edge of this plate contacts the circumference of an ink fountain roller (6) via springs (18, 19) acting on the intermediate plate. The wall has a slideway (10) in which the plates (11, 14, 13) are mounted. The slideway has a reinforced region (12) on one of its sides which is proximate the ink fountain roller (6). The side wall (5) thus more effectively seals an ink fountain against leakage.
Claims9
A side wall (5) for use with an ink fountain (3) of a printing machine, the ink fountain having a blade-shaped bottom (4) and an ink fountain roller (6), said side wall having an edge adapted for contact with the ink fountain roller (6) and comprising:
- two spaced-apart plates (11, 14) and an intermediate plate (13), said intermediate plate having a front edge (13a) in the shape of an arc of a circle adapted for contact with said ink fountain roller;
- said intermediate plate of each side wall being mounted between said two spaced-apart plates (11, 14), said intermediate plate being movable and tiltable with respect to said spaced-apart plates, said front edge of said intermediate plate being biased so as to contact the outer circumferential surface of said ink fountain roller (6) when the side wall is installed against the ink fountain roller, the biasing being achieved by means of spring elements (18, 19) acting on said intermediate plate (13);
- a slideway (10) in which the spaced-apart plates and said intermediate plate (11, 14, 13) are adapted for mounting on the bottom of said ink fountain;
- and
- said slideway (10) having a reinforcement member (12) adapted for contact with the circumferential surface of said ink fountain roller, said reinforcement member comprising a small plate adapted for contacting said ink fountain roller (6).
An ink fountain assembly for use with a printing machine, said ink fountain assembly comprising;
- an ink fountain roller (6);
- a blade-shaped bottom (4) having an edge contacting the ink fountain roller (6);
- two side walls (5) contacting said Made-shaped bottom (4) each side wall (5) comprising
- at least two spaced-apart plates (11, 14) and an intermediate plate (13), said intermediate plate having a front edge (13a) in the shape of an arc of a circle which contacts said ink fountain roller;
- said intermediate plate of each side wall being mounted between said at least two spaced-apart palates, each said intermediate plate being movable and tiltable with respect to said at least two spaced-apart plates, said front edge of said intermediate plate being biased into contact with the outer circumferential surface of said ink fountain roller (6) by means of spring elements (18, 19) acting on said intermediate plate (13);
- and
- a slideway (10) in which at the spaced-apart plates and said intermediate plate (11, 14, 13) are mounted on the bottom of said ink fountain, said slideway (10) having a reinforcement member (12) contacting the circumferential surface of said ink fountain roller, each said reinforcement member comprising a small plate of hard material.
