摘要： Provided is a medium conveying apparatus capable of conveying a medium satisfactorily. A medium conveying apparatus includes a first conveyance roller pair, a first pressing part to press one roller of the first conveyance roller pair to the other roller, a second conveyance roller pair, and a second pressing part to press one roller of the second conveyance roller pair to the other roller. A pressing force of the second pressing part is less than a pressing force of the first pressing part. At least one roller of the first conveyance roller pair and at least one roller of the second conveyance roller pair are driven by a same motor. A diameter of at least one roller of the second conveyance roller pair is greater than a diameter of at least one roller of the first conveyance roller pair.

摘要： In order to be able to manufacture large-caliber reels of high quality in a twin drum reel-up, the king rolls (11) and (12) have different diameters and are situated at different elevations. The main load of the reel is carried by the king roll (11), while the king roll (12) contacts the reel (13) with the smallest possible nip pressure which just suffices for transferring the torque difference required for generating the desired winding tension of the reel. The king roll (12) may be lowered as the diameter of the reel increases, namely depending on the fact if the winding shaft (13A) is displaced along a predetermined line of motion (14; 15), preferably a linear vertical or slightly tilted line of motion. An additional center drive which is made possible due to the aforementioned measures may additionally improve the winding result. A handling device (50) serves as a multifunction device for exchange of reels, in particular for the ejection of the reels, the clamping of the end of the web and the moving of the end of the web into the position for the next reel, as well as the separation of the finished reel from the web (1; 1', 1", . . . ).

摘要： A method of and device for winding webs of material, especially webs of paper or cardboard, on cores. In the method, the web is wound on cores in a bed created by two drums and the full reels are ejected from the bed above one drum by an arm that swings around the other. Wound reels with a short diameter are compressed between the ejection surface on the ejection arm and the drum that the reel is being ejected over and are lifted out of the bed by a rotation of the drum. The device has a mechanism for ejecting full reels that swings forward toward the bed created by two drums and has an ejection arm with an ejection surface that extends more or less radially toward the drum that the reel swings around. The ejection surface in one embodiment extends as far as the drum that the reel swings around and, once is has swung forward, its upper demarcation will extend into the vicinity of the adjacent drum. Another embodiment of the device also has a combination reel-ejection and core-insertion mechanism that has an ejection arm and a core-insertion structure, whereby the ejection surface on the arm terminates at a distance from the drum and the core-insertion structure releases the cores through the space between the ejection surface and the drum. The ejection surface can, when the ejection-and-insertion mechanism is at rest, be moved or extended toward the drum that the reel swings around.
摘要翻译：一种用于将纤维网，特别是纸或纸板网卷绕在芯上的方法和装置。在该方法中，纤维网缠绕在由两个鼓形成的床中的芯上，并且通过围绕另一个滚动的臂将完整的卷轴从一个滚筒上方的床上弹出。具有短直径的卷绕卷轴在喷射臂上的喷射表面和卷筒被弹出的滚筒之间被压缩，并且通过滚筒的旋转而被提升出床。该装置具有用于弹出从两个鼓形成的向前摆动的整个卷轴的机构，并具有一个具有弹出臂的弹出臂，该弹出臂的多个或多或少径向延伸，使得卷轴周围摆动。在一个实施例中，喷射表面延伸到卷筒周围摇摆的鼓上，并且一旦向前摆动，其上分界线将延伸到相邻滚筒附近。该装置的另一个实施例还具有组合的卷轴排出和芯插入机构，其具有弹出臂和芯插入结构，由此臂上的喷射表面终止于离滚筒一定距离，并且芯插入结构释放芯通过喷射表面和滚筒之间的空间。当喷射和插入机构静止时，喷射表面可以朝向卷筒移动或延伸，使得卷轴周围摆动。
