| 20120285018 | METHOD OF MANUFACTURING ROLLER - A workpiece is fixed by a retracting mechanical chuck mounted on a spindle head of a five-axis control machining center. The apparent outer diameter of the workpiece is increased by a jig. Clamp surfaces of the jaws and a support surface of the jig are formed on the machining center. A cutting tool is mounted on a spindle by an automatic tool exchanger. The workpiece is rotated about an axis to grind an end surface of the workpiece to approximately a predetermined target shape, which is a spherical surface. A grinder is then mounted on the spindle by the automatic tool exchanger, and the grinder is set relative to the workpiece by five-axis control such that the inclination angle, the offset amount, etc. satisfy a predetermined relationship according to the desired grinding. The grinder is then fed in the Z-axis direction to form the spherical surface by grinding. | 11-15-2012 |
| 20120311861 | MANUFACTURING METHOD OF ROLLER USED FOR MANUFACTURING PATTERNED RETARDATION FILM - A manufacturing method of a roller used for manufacturing a patterned retardation film is provided. The manufacturing method includes the following steps. A roller having a rotational axis and a roller surface is provided. An engraving device having an engraving end is provided. The engraving end has a plurality of sub-micron slots which are constructed in parallel with each other. The engraving device engraves the roller surface with a first depth to form a plurality of first sub-micron grooves. The engraving device engraves the roller surface with a second depth to form a plurality of second sub-micron grooves. | 12-13-2012 |

| 20090094835 | Method of replacing supporting bearing for rolling roll - A supporting bearing is replaced with a new supporting bearing by conducting a first step and a second step. In the first step., an old inner ring before replacement is replaced with a new inner ring having an inner ring raceway diameter same as the old inner ring, and an axial length of an inner ring raceway face longer than the old inner ring so that a rolling roll is supported by this new inner ring in combination with an old outer ring and old cylindrical rollers. Thereafter, in the second step, the old cylindrical rollers are replaced with new cylindrical rollers having an axial length longer than the old cylindrical rollers, and simultaneously, the old outer ring is replaced with a new outer ring having an axial length of an outer ring raceway face longer than the old outer ring. | 04-16-2009 |
| 20100126021 | METHOD FOR REFURBISHING PRESSURE MEMBERS - The present invention provides a method of resurfacing a pressure member in a printer having a fuser member that is externally heated by a heater roller. The method includes providing a pressure member having an outer surface of a high temperature fluorothermoplastic. When it is determined that the outer surface is in need of resurfacing, the fuser member is removed from the printer, and the pressure member is mounted in the place of the fuser member. The pressure member is rotated at a speed of at least 1 rpm while engaging the outer surface of the fuser member with the heating roller normally used to heat the fuser member at a pressure of at least 5 psi at a temperature of at least 10° C. below the fluorothermoplastic melting temperature for a time sufficient to resurface of the outer surface of the pressure member. | 05-27-2010 |
| 20130025127 | REINFORCED ROLL AND METHOD OF MAKING SAME - A method of one of manufacturing and maintaining a grinding roll comprises removably attaching an article adapted for use as a wear resistant working surface to an external surface a cylindrical core. The article includes a metal matrix composite comprising a plurality of inorganic particles dispersed in a matrix material comprising a metal or a metal alloy. The melting temperature of the inorganic particles is greater than the melting temperature of the matrix material. Hard elements are embedded in the metal matrix composite. The wear resistance of the metal matrix composite is less than the wear resistance of the hard elements, and the metal matrix composite wears away when the grinding roll is in use, thereby providing or preserving gaps between the hard elements at a working surface of the roll. | 01-31-2013 |
| 20140165404 | ROLLER CHANGING APPARATUS FOR FURNACES - Embodiments of the invention relates to a roller changing apparatus for changing a roller from a multiplicity of rollers in a furnace for the thermal treatment of components, wherein the roller changing apparatus has a housing which can be closed off and in which a first protective gas atmosphere can be formed, and a roller handling device which is arranged at least partially in the housing, and which is designed to remove the roller to be exchanged from the furnace and to fit a replacement roller in the furnace while maintaining a high temperature and a second protective gas atmosphere in the furnace during the roller change. | 06-19-2014 |

| 20110192029 | SUPPORT ROLL FOR A ROLLING MILL - Disclosed is a support roll for a rolling mill, such as a plate rolling mill, flat rolling mill, or similar, comprising a jacket and a roll shaft which is embodied in several parts. The invention also relates to a method for producing a support roll. | 08-11-2011 |
| 20130036610 | Notchless Core - Providing a spool end with a flange, a post, and a blade on the post which extends to the flange. The post is inserted into a core including penetrating the core with the blade. The spool end is rotated including imparting a rotating force upon the core using the blade. Preferably, at least three blades are used for stability and even transmission of rotational force. | 02-14-2013 |
| 20140173901 | DISK AND PROCESS FOR PRODUCING BASE MATERIAL FOR DISK, AND DISK ROLL - The present invention relates to a process for producing a base material for disks of disk rolls, in which the disk roll contains a rotating shaft and a plurality of the disks fitted on the rotating shaft by insertion whereby the outer peripheral surface of the disks serves as a conveying surface, in which the process contains molding a slurry raw material containing inorganic fibers, an inorganic filler having an aspect ratio of from 1 to 25 and an inorganic binder into a plate shape; and drying the molded plate. | 06-26-2014 |
