20140274636 | APPARTUS FOR, AND METHOD OF, PRODUCING A BAG FROM PAPER, AND PAPER BAG - A bag machine for production of bags made of paper material includes an unwinding device to unwind and feed paper material in a transport direction (x), a device to produce weakening lines partially offset in direction (x), so that a first wall of the bag continues in at least one tab that extends beyond a second wall, a tube-forming device, in which side areas are folded to form an overlapping area, a separation device to separate tube sections along the weakening lines, and a bottom formation device, in which areas of a leading end of the tube section are folded and fastened onto an outer wall thereof. The machine has a device for application of adhesive surfaces to the paper material, with which an adhesive surface is applied to an area of the paper material that represents the side of the tab facing the second wall in the finished bag. | 09-18-2014 |
20140251169 | METHOD FOR ADJUSTING THE DISTANCES BETWEEN CYLINDERS OF AN INKING UNIT AND PRINTING MACHINE - A method for adjusting the distances between cylinders of an inking unit limiting at least two cylinder gaps and in which the distances are adjusted based on measurements, which are gathered from the surface of at least one of the cylinders of the inking unit. | 09-11-2014 |

20120079954 | DEVICE AND METHOD FOR SETTING AT LEAST TWO CYLINDERS OF A PRINTING MACHINE AGAINST EACH OTHER - A printing machine with at least one inking unit which has at least two cylinders which are set against each other during the printing operation and can be rotated by at least one drive. The printing machine is provided with sensors for recording parameters of the rotary motion of the cylinders such as the torque and speed. A setting mechanism is provided for setting the at least two cylinders against each other in radial direction. The control unit is configured to trigger the setting mechanism to set the at least two cylinders against each other. The at least two cylinders are brought to different circumferential velocities and set against each other. The relative position of the two cylinders is recorded or maintained when at least one parameter of the rotary motion of the at least two cylinders exceeds a threshold value. | 04-05-2012 |
