Abstract
Roll, method of forming roll and method of operating roll. Roll includes a roll body, a deformable cover coupled to the roll body, a pluggable input, a pluggable output, and a coolant contained within the roll body at least in an amount sufficient for a rimming mode to occur during normal operation of the roll. The present abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
Claims20
A roll comprising:
- a roll body;
- a deformable cover coupled to the roll body;
- at least one pluggable input;
- and
- a coolant contained within the roll body at least in an amount to provide cross-machine direction heat transfer during normal operation of the roll.
A method for forming a cooled roll composed of a single shell covered roll having an open internal cavity, comprising:
- adding coolant into the internal cavity at least in an amount to provide cross-machine direction heat transfer during normal operation of the roll;
- and
- plugging a pluggable input of the roll.
A method for operating a roll of a paper machine composed of a single shell covered roll having an open internal cavity, comprising:
- adding an amount of coolant into the internal cavity in an amount greater than an amount for operating in a rimming mode during normal operation of the roll;
- plugging a pluggable input of the roll;
- and
- rotating the roll.
