20100294015 | Embossing method and apparatus for producing diffraction-active structures - In an apparatus and a method for producing diffraction- and interference-active structures by micro-pattern stamping a metal object, a micro-stamping arrangement is provided including a micro-stamping station with a micro-pattern stamp for generating a diffraction-active structure on the metal object, an application station for applying a protective layer to the diffraction-active structure and a macro-stamping station for applying a macroscopic image relief over the diffraction active structure while it is protected by the protective layer. | 11-25-2010 |
20100294144 | Precision press - In a press with a plunger which is supported by an elastically deformable support structure so as to be linearly movable but otherwise rigidly engaged and with a drive arrangement for the controlled movement of the plunger, the drive arrangement includes no friction or antifriction support joints so that the plunger guide structure is not affected by position errors generated by oil films in bearings or wear of bearings generated by the high press forces effective during operation of the press which could squeeze oil films out of bearing gaps. | 11-25-2010 |
20100320856 | Eccentric press with direct drive - A press drive including an electric motor with a stator and a rotor and permanent magnets arranged around the circumference of the rotor. The rotor includes at least one eccentric integrally therewith and rotatably supported with the rotor. The stator is supported on the rotor by bearings arranged adjacent the eccentrics and is held stationary by torque struts. | 12-23-2010 |
20110083568 | Direct drive for a press - The invention relates to a press having an electric direct drive, without any motion transmitting means, such as, for example, gears or gear drives wherein the electric direct drive is located between an eccentric | 04-14-2011 |
20130025475 | PRESS WITH SLIDING BEARING LUBRICATION AS A FUNCTION OF THE PRESS OPERATING STATE AND METHOD FOR OPERATION OF SAID PRESS - A press, a method for operating the press, and a lubricating arrangement for the press or for another working machine. The press comprises a press drive that is connected with a ram of the press, which ram can be moved via a transmission in a working direction (Z). The transmission comprises at least one sliding bearing with one and, preferably, several lubricating points. In a first press operating state, all the lubricating points of the sliding bearing are supplied with lubricant at a first lubricant pressure (p | 01-31-2013 |
