Abstract
Abstract Abstract: A press roll interacting with a mating roll has an elastic deformable outer casing to form ?? extended nip and an inner casing to support the outer ????? ?nits periphery, whereby the inner casing is stationary and a pressure pad that can be pressurized is provided in the nip between the inner and outer casing. The outer casing is driven by means of at least one drive roll that can be pressed against the outer casing. (Fi. 1) (IP)

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
A press roll suitable for use with a paper machine, which press roll interacts with a mating roll to drain a fibrous web being carried by a felt or fabric, said press roll having an elastic deformable outer casing to form an extended nip with said mating roll and further having an inner casing to support the outer casing on its periphery, characterized in that the inner casing is stationary, that the outer casing is slidingly mounted on said inner casing, and that in the region of said nip, at least one first pressure pad which is adapted to be subjected to pressure from the inside is located so as to abut on the inside of the outer casing.
Claim 2
Dependent Claim
119 words
A press roll suitable for use with a paper machine, which press roll interacts with a mating roll to drain a fibrous web being carried by a felt or fabric, said press roll having an elastic deformable outer casing to form an extended nip with said mating roll and further having an inner casing to support the outer casing on its periphery, characterized in that the inner casing is stationary, that the outer casing is slidingly mounted on said inner casing, and that in the region of said nip, at least one first pressure pad which is adapted to be subjected to pressure from the inside is located so as to abut on the inside of the outer casing.
Claim 3
Dependent Claim
32 words
A press roll according to claim 1, characterized in that the said outer casing is driven by means of at least one drive roll that can be pressed against the outer casing.
Claim 4
Dependent Claim
24 words
A press roll according to claim 1, characterized in that recesses for supplying a lubricant are provided on the outside of the inner casing.
Claim 5
Dependent Claim
18 words
A press roll according to claim 3, characterized in that said recesses taper in the direction of rotation.
Claim 6
Dependent Claim
53 words
A press roll according to claim 2, characterized in that a further pressure pad, located so as to abut on the inside of the outer casing and adapted to be pressurized from the inside, is arranged in the inner casing at a point at which a drive roll presses against the outer casing.
Claim 7
Dependent Claim
40 words
A press roll according to claim 1, characterized in that said first pressure pad has in the nip a recess open towards said outer casing, said recess being capable of being pressurized via restriction bores in said first pressure pad.
Claim 8
Dependent Claim
33 words
A press roll according to claim 1 or claim 2 or claim 3, characterized in that the inner shell is supported by a stationary yoke in the manner of a deflection adjusting roll.
Claim 9
Dependent Claim
33 words
A press roll according to claim 4 or claim 5 or claim 6, characterized in that the inner shell is supported by a stationary yoke in the manner of a deflection adjusting roll.
Claim 10
Dependent Claim
120 words
A press roll suitable for use with a paper machine, which press roll interacts with a mating roll to drain a fibrous web being carried by a felt or fabric, said press roll having an elastic deformable outer casing to form an extended nip with said mating roll and further having an inner casing to support the outer casing on its periphery, characterized in that the inner casing is stationary, that the outer casing is slidingly mounted directly on said inner casing, and that in the region of said nip, at least one first pressure pad which is adapted to be subjected to pressure from the inside is located so as to abut on the inside of the outer casing.
Claim 11
Dependent Claim
120 words
