Abstract
Abstract A composite roll for a rolling mill is constituted by a sleeve and an axially adjustable arbor therewithin. The ends of the sleeve are closed by end members, one of which has an axial passage with a diameter smaller than the bore diameter of the sleeve. An adjustment rod is secured to the arbor and passes through the passage of the end member. By operation of the adjustment rod, the position of the arbor within the sleeve and hence the axial compliance of the roll can be adjusted.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
A rolling mill comprising at least four rolls, at least one of said rolls having axial compliance and comprising: a sleeve having a bore therethrough and forming the barrel of said roll; first and second end members secured on said bore at respective ends of said sleeve, at least one of said end members having therethrough a passage with a diameter significantly less than the diameter of said bore; an arbor located within said bore between said end members and axially movable within said bore to adjust the axial compliance of said roll; a roll neck integral with each said member, for mounting said roll in a rolling mill, one said neck having therein a cylinder-forming recess; and adjustment means for said arbor, said means including a piston located in said recess and connection means operatively attached between said arbor and said piston and passing axially through said passage of said one end member.
Claim 2
Dependent Claim
154 words
A rolling mill comprising at least four rolls, at least one of said rolls having axial compliance and comprising: a sleeve having a bore therethrough and forming the barrel of said roll; first and second end members secured on said bore at respective ends of said sleeve, at least one of said end members having therethrough a passage with a diameter significantly less than the diameter of said bore; an arbor located within said bore between said end members and axially movable within said bore to adjust the axial compliance of said roll; a roll neck integral with each said member, for mounting said roll in a rolling mill, one said neck having therein a cylinder-forming recess; and adjustment means for said arbor, said means including a piston located in said recess and connection means operatively attached between said arbor and said piston and passing axially through said passage of said one end member.
Claim 3
Dependent Claim
146 words
A rolling mill roll having adjustable axial compliance comprising: a sleeve having a bore therethrough and forming the barrel of said roll; first and second end members secured on said bore and respective ends of said sleeve, at least one one of said end members having therethrough a passage with a diameter significantly less than the diameter of said bore; an arbor located within said bore between said end members and axially movable within said bore to adjust the axial compliance of said roll; a roll neck integral with each said end member, for mounting said roll in a rolling mill, one said neck having therein a cylinder-forming recess; and adjustment means for said arbor, said means including a piston located in said recess and connection means operatively attached between said arbor and said piston and passing axially through said passage of said one end member.
Claim 4
Dependent Claim
146 words
A rolling mill roll having adjustable axial compliance comprising: a sleeve having a bore therethrough and forming the barrel of said roll; first and second end members secured on said bore and respective ends of said sleeve, at least one one of said end members having therethrough a passage with a diameter significantly less than the diameter of said bore; an arbor located within said bore between said end members and axially movable within said bore to adjust the axial compliance of said roll; a roll neck integral with each said end member, for mounting said roll in a rolling mill, one said neck having therein a cylinder-forming recess; and adjustment means for said arbor, said means including a piston located in said recess and connection means operatively attached between said arbor and said piston and passing axially through said passage of said one end member.
Claim 5
Dependent Claim
31 words
A rolling mill roll as claimed in claim 2, wherein said connection means is an actuating rod secured to said arbor and extending out of said end member to said piston.
Claim 6
Dependent Claim
33 words
