Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
112 words
Method for balancing an unbalanced roll, comprising the steps of determining one or more locations on an inner surface of a roll mantle of an unbalanced roll to which the application of a balancing weight will result in the weight of said roll being substantially equally distributed both about its axis of rotation and across its length, placing onto said inner surface of said mantle of the unbalanced roll, a fluidizable balancing agent only at said one or more locations on said inner surface required for balancing the unbalanced roll, and allowing the agent to adhere and harden at said one or more locations while said roll is both stationary and nonrotating.
Claim 2
Dependent Claim
112 words
Method for balancing an unbalanced roll, comprising the steps of determining one or more locations on an inner surface of a roll mantle of an unbalanced roll to which the application of a balancing weight will result in the weight of said roll being substantially equally distributed both about its axis of rotation and across its length, placing onto said inner surface of said mantle of the unbalanced roll, a fluidizable balancing agent only at said one or more locations on said inner surface required for balancing the unbalanced roll, and allowing the agent to adhere and harden at said one or more locations while said roll is both stationary and nonrotating.
Claim 3
Dependent Claim
24 words
The method of claim 1, comprising the additional step of placing the balancing agent onto an inner face of a mantle of the roll.
Claim 4
Dependent Claim
21 words
The method of claim 2, comprising the additional step of introducing the balancing agent at the balancing location through a pipe.
Claim 5
Dependent Claim
22 words
The method of claim 3, comprising the additional step of passing the balancing agent into the pipe by means of an actuator.
Claim 6
Dependent Claim
16 words
The method of claim 4, wherein the actuator is a cylinder with a piston mounted therein.
Claim 7
Dependent Claim
36 words
The method of claim 3, comprising the additional step of introducing the pipe into an interior space of the roll mantle through a hole provided in a flange situated at an end of the roll mantle.
Claim 8
Dependent Claim
75 words
The method of claim 1, comprising the additional step of rotating the roll so that the balancing location is rotated to a first position, whereby the balancing agent remains exactly at said balancing location before hardening, then rotating the roll again only after the balancing agent has hardened so as to bring another balancing location to the lowest position, and then again conveying the balancing agent to said another balancing location now at first position.
Claim 9
Dependent Claim
18 words
The method of claim 6, comprising the additional step of plugging the hole after the balancing is completed.
Claim 10
Dependent Claim
17 words
The method of claim 1, wherein the balancing agent is polyurethane or silicon mix or epoxy resin.
Claim 11
Dependent Claim
21 words
The method of claim 1, comprising the additional step of cleaning the roll face before the balancing agent is applied thereto.
