Abstract
Two press units have axes which lie in a pressing plane which is inclined to the vertical direction and they form a press nip with each other. The two press units are supported by bearing brackets which are coupled in pairs to each other by detachable tension bars which transmit the pressing force. The bearing brackets of the one press unit are supported rigidly (i.e. directly on a machine frame, foundation, or the like) and bear at least a part of the weight of the other press unit. A support device on the machine frame, foundation, or the like at least temporarily takes up a component of the weight of the other press unit which is directed transverse to the pressing plane.
Claims25
A roll press for the treatment of a traveling paper web, the roll press comprising:
- a first press unit having a first axis and a second press unit having a second axis, the first and second axes lying in a pressing plane, the first and second press units being placed with respect to each other for defining a press nip through which the web travels;
- the first press unit including a stationary support member, a traveling press element supported on and rotating around the support member for defining a jacket for cooperating in the press nip with the second press unit;
- an internal pressing device related to the support member moveable for causing such radial movement of the traveling press element as to create the press nip and to produce a pressing force that acts on the web in the press nip;
- each of the first and second press units having opposite ends;
- respective first bearing brackets at the ends of the first press unit and respective second bearing brackets at the ends of the second press unit;
- detachable tension bars at the ends of the press units including a respective tension bar coupling the first and second bearing bracket at each end of the press unit, the tension bars serving for transmitting pressing force between the bearing brackets;
- a machine support;
- the first bearing brackets being rigidly supported by the machine support for supporting the first press unit and for supporting at least part of the weight of the second press unit;
- the first and second press units being so placed that the pressing plane defined by the first and second axes defines an acute angle with respect to the horizontal;
- a support device on the machine support for at least temporarily taking up a component of the weight of the second press unit, which weight component is directed transversely to the pressing plane.
