    • A method and device for feeding sheets one by one from a stack of sheets to a transportation device are described. The sheet-feeding device comprises a number of parallel, separately driven shafts which are equidistantly spaced from one another and are enclosed in a low-pressure chamber and carry a plurality of feeding wheels. A separating device is arranged above the low-pressure chamber. At least one relieving element is arranged in a vertically displaceable manner between a sheet-supporting position and a non sheet supporting position. Each relieving element is positioned before each wheel shaft and the movement thereof as well as the rotational movement of the wheels are controlled by the control unit depending on the position of the rear edge of the sheet relatively to the wheels.
    • 描述了一张一张地从一叠片材运送到运输装置的方法和装置。 片材供给装置包括多个平行的单独驱动的轴,它们彼此等距间隔开并被封闭在低压室中并且携带多个进给轮。 分离装置设置在低压室的上方。 至少一个释放元件以可垂直移位的方式布置在片材支撑位置和非片材支撑位置之间。 每个卸载元件定位在每个轮轴之前,并且其运动以及轮的旋转运动由控制单元根据片材的相对于车轮的后边缘的位置来控制。

    • In a machine for forming articles of sheet material, an orderly succession of flat blanks is fed along a forming path on a roller conveyor having powered rollers equally spaced with a given spacing; on the roller conveyor, the blanks are maintained contacting the rollers by idle-wheel pressure devices, and are deformed by folding devices; the pressure devices and folding devices being fitted to respective gantry-type frames having respective removable cross members, and which can be set to a number of predetermined reference positions and locked in such positions releasably with respect to the roller conveyor; and a continuous guide and slide adjusting assembly being interposed between each frame and the respective pressure devices and folding devices to adjust the position of the devices on the roller conveyor as a function of the shape and size of the blanks.
    • 在用于成型片材的机器中,有顺序地连续的平坯被沿着具有以给定间隔等间隔的动力辊的辊式输送机上的成形路径供给; 在辊式输送机上,坯料通过惰轮压力装置保持与辊接触,并通过折叠装置变形; 压力装置和折叠装置安装到具有相应的可移除横向构件的各个机架式框架上,并且可以将其设置为多个预定的基准位置并相对于滚筒输送机可释放地锁定在这些位置; 以及连续的引导和滑动调节组件,其被插入在每个框架和相应的压力装置和折叠装置之间,以根据坯件的形状和尺寸来调节装置在辊式输送机上的位置。
