20080305937 | ROLLER BODY WITH PROFILE CHANNELS FOR A THERMAL TREATMENT FLUID - A roller body for treating a web-shaped material, comprising a shell | 12-11-2008 |
20090011912 | DEAD-SHAFT ROLLER WITH AEROSTATIC ROTARY UNION - A dead-shaft roller having a shaft and a roll with a fluid circulation passage therein, and at least two bearings support the roll on the shaft. A rotary union is positioned at least one end of the roll, possibly both. The rotary union has a rotatable sleeve and a non-rotating sleeve. The rotatable sleeve has a fluid conducting path therein, such that the fluid conducting path is in fluid communication with the fluid circulation passage in the roll. The non-rotating sleeve is positioned adjacent and internal to the rotatable sleeve. The non-rotating sleeve has a first fluid port therein such that the fluid conducting path is in fluid communication with the first fluid port at a first fluid transfer zone. At least two air bearings are present, mounted between the rotatable sleeve and the non-rotating sleeve, such that the air bearings are on opposite sides of the first fluid transfer zone. | 01-08-2009 |
20090156379 | CLOSED SYSTEM COOLED COVERED ROLL AND METHODS OF FORMING AND OPERATING COOLED COVERED ROLL - 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. | 06-18-2009 |
20090258771 | SYSTEM AND METHOD FOR REDUCING CURRENT EXITING A ROLL THROUGH ITS BEARINGS - A system includes a roll formed from a conductive material, where the roll is configured to rotate about an axis. The system also includes an induction heating workcoil configured to generate currents within the roll. The induction heating workcoil is unbalanced and is oriented so that minimal currents flow in a direction substantially parallel to the axis of the roll. The induction heating workcoil could include one or more substantially U-shaped or C-shaped cores and at least one coil each wound around at least one of the one or more cores. Also, the roll may further include a shaft and bearings, and the induction heating workcoil can be positioned so that the currents do not flow substantially through the bearings. | 10-15-2009 |
20100144506 | GUIDE ROLLER AND FIBER BUNDLE ARRANGING DEVICE - A guide roller | 06-10-2010 |
20110237413 | IMAGE HEATING APPARATUS AND PRESSURE ROLLER USED FOR IMAGE HEATING APPARATUS - A pressure roller forming a nip portion for contacting to a heating member to pinch and convey and heat recording material includes: a core metal and an elastic layer containing filler, the elastic layer containing the filler including thermal conductive filler with length of not less than 0.05 mm and not more than 1 mm and with thermal conductivity λ | 09-29-2011 |
