Abstract
The axes of a first press roll (1) and of a second press roll (3) lie in a press plane (E). Each of the press rolls has a journal pin (2) and (4) respectively. The first press roll is supported in a first bearing pedestal (5). The second press roll rests in a second bearing pedestal (6) which is coupled to the first bearing pedestal (5) by utilizing flexurally soft tension bars (7, 8). In the unloaded condition of the roll press, the second bearing pedestal (6) rests on the first bearing pedestal (5). In the loaded condition, play (p) is established between the bearing pedestals (5 and 6) so that the bearing pedestals (5 and 6) are displaceable axially relative to each other.
Claims34
A roll press comprising:
- a first press roll having a first axis and a periphery;
- the first press roll having an individual first end at each of its opposite ends;
- one of said first ends being axially spaced in a first direction from another of said first ends;
- a second press roll having a second axis and a periphery;
- the second press roll having an individual second end at each of its opposite ends;
- one of said second ends being axially spaced in said first direction from another of said second ends;
- the first and the second rolls being oriented so that the first and second axes define a press plane and so that the roll peripheries cooperate to form a press nip;
- a pressing device adapted to load and unload the roll press;
- a first bearing pedestal located at and supporting said one of the first ends of the first press roll;
- a second bearing pedestal located at and supporting said one of the second ends of the second press roll;
- the second pedestal being movable relative to the first pedestal in the press plane;
- at least one tension bar extending between the first and the second bearing pedestals and extending substantially parallel to the press plane and perpendicular to the first and second press roll axes;
- the tension bar having little tension when the roll press is in an unloaded condition;
- the tension bar being deformable for enabling relative movement of the first and second pedestals parallel to the press plane when the roll press is in a loaded condition.

- each tension bar having little tension when the roll press is in an unloaded condition;
- each tension bar being movable for enabling relative movement of the first and second pedestals when the roll press is in a loaded condition;
- the first and the second press rolls having respective first and second diameters;
- the tension bars having respective outer sides that face away from one another, and the tension bars being so shaped, sized and located that for a roll press construction in which one of said first and second diameters is sized differently than the other of said first and second diameters, the outer sides of the tension bars are spaced apart by a distance that is at most substantially the same size as the larger one of the first and the second diameters.
