摘要： A folding apparatus for rotary roller printing presses, having at least one collecting or crosswise folder, positioned behind which there is at least one sword folder composed of a folding sword interacting with a pair of folding cylinders, the folded material being conveyed to the sword folder via a belt guide having upper and lower belts and, in the region of the folding sword, passing positioned limit stops for the folded material. The belt guide has at least two strands positioned one behind the other and being driven at opposingly stepped speeds, with the faster-running strand on the collecting or crosswise folder side, having a run-out groove opening wedge-shapedly, beyond which least one locating stop moving at the speed of the slower-running strand, on the sword folder side, is positioned, its path at least partly overlapping with the feeding-in region of the equally fast belt guide strand.

摘要： Folding device for roller rotating printing presses for folding a prefolded pack of sheets which is fed by a pair of endless conveyor belts underneath a folding knife in parallel direction of its feeding movement wherein at the arriving end and on both sides of the folding knife, a finger is moved into the feeding path of the pack of sheets so as to engage an advancing front edge of the pack of sheets. The finger is forcibly moved into rotation by a shaft which runs laterally beneath the endless conveyor belts whereby the rotation moves the finger in a working cycle above the lower plane of the endless conveyor belts and the finger runs slowly in direction of the feeding motion, but more slowly than the same.
摘要翻译：用于折叠折叠的折叠包装纸的辊旋转印刷机的折叠装置，其由折叠刀在其进给运动的平行方向上的一对环形传送带进给，其中在折叠刀的到达端和两侧，手指移动到纸张包的进给路径中，以便接合纸张包的前进前边缘。手指通过横向在环形输送带下方延伸的轴被强制地转动，由此旋转使手指在环形输送带的下平面上方的工作循环中移动，并且手指在进给运动方向上缓慢地运动，但是比同样慢。
