| 20130040794 | Notchless Core - A flange having a post extending therefrom and a blade extending from the post to the flange. A core of a spool is designed to be positioned on the post for the blade to penetrate the core inside diameter and to provide torque to rotate the spool. | 02-14-2013 |
| 20090124475 | FIXING MEMBER - The present invention is a roller for use in a fuser assembly of a reproduction apparatus. The roller includes a generally elongated substantially cylindrical tube having two ends. End gudgeons having a cylindrical wall extending from a surface of the gudgeon matching the cylindrical tube are welded to the ends of the cylindrical tube. The present invention is also a method to manufacture a fixing roller or core. | 05-14-2009 |
| 20130072366 | COIL-TUBE CHUNK FOR A ROLL FEEDER - A coil-tube chunk for a roll feeder has at least one colleting device. Each of the at least one colleting device has a base and a chunk. The base has a mounting stand, a sharp-tooth mount and multiple screwing rods. The mounting stand is formed on and protrudes from the base. The sharp-tooth mount is formed on the base around the mounting stand. The screwing rods are respectively and securely mounted on the sharp-tooth mount. The chunk is mounted securely on the base and has a guiding face, multiple grooves and multiple engaging teeth. The guiding face is aslantly formed on an external surface of the chunk. The grooves are formed in the external surface and the guiding frace of the chunk at intervals. The engaging teeth are formed on the external surface and the guiding face of the chunk between the grooves. | 03-21-2013 |
| 20090275453 | Roller for Various Machines and Apparatus - A roller for various machines and apparatus includes at least one roller core having a hollow body and two opposite communicable open ends, and at least one end cap joined to at least one of the two opposite open ends of the roller core by way of friction welding. The end cap is provided on one of two opposite sides with an axially outward extended engaging section for inserting into the hollow body of the roller core, and an annular groove is provided around the engaging section. With the above arrangements, the roller can be easily produced at reduced manufacturing cost and having a reduced weight but increased structural strength. | 11-05-2009 |
| 20120208685 | GUIDE ROLLER - Disclosed is a guide roller wherein bearings are held in a housing, and liquid mixed with abrasive grains is prevented from entering the interior of the housing through a small hole, thereby improving service life. The guide roller is configured to comprise a housing wherein the bearings are held in the housing, and the housing has a shaft hole wherein a support shaft is inserted that is installed upon the bearings. The shaft hole is formed to have a tapered wall, and the diameter of the hole decreases continuously toward the interior of the housing. | 08-16-2012 |
| 20120021882 | PIN AND DOUBLE PROFILE ROLL ASSEMBLY - A pin and double roll assembly, in which mounted on the pin are a horizontal thrust bearing and a vertical roller bearing. Mounted over the roller bearing is a double sided seaming roll. A cap over the roller bearing and retained against the double sided seaming roll and retained by a screw holds the parts in relation to each other. The thrust bearing and the roller bearing allow the double sided seaming roll to rotate on the pin during use. A sealing ring between a lip on the pin and the double sided seaming roll seals the part such that water or corrosive liquids cannot reach the thrust bearing or roller bearing as the part is used. | 01-26-2012 |
