Abstract
Apparatus for the pressure treatment of webs of material, such as the wet section of a paper-making machine, including a damping device fixedly connected to the protruding end of the roll for damping vibrations of the roll occuring during rotation thereof. The damping device comprises a pair of annular mass rings which surround the protruding roll end and are resiliently supported within an enclosed housing which includes frictional elements bearing against the rings.
Claims24
Apparatus for the pressure treatment of webs of material comprising:
- a roll having a working roll circumference at its outer diameter;
- ends protruding from the roll to which external forces may be applied for supporting the roll, each protruding end comprising an inner region extending axially outwardly from said roll and an outer region extending axially outwardly from said inner region;
- an external support structure connected to the inner region of each protruding end for supporting the roll;
- and
- a device external to the roll damping vibrations of the roll during rotation thereof, said damping device being attached to, and solely supported by, one of said outer regions.
A damping device for a roll used in the pressure treatment of webs of material comprising:
- (a) an enclosed housing having means for connecting the device to an end of a roll without radial play;
- (b) means for damping roll vibrations including
- (i) an inertial mass;
- and
- (ii) a plurality of holding elements connected to the housing and the mass, permitting radial movement of the mass
- whereby the mass is radially movable relative to the housing.
