    • In a machine for cutting a paper web into sheets and forming them into a stack, the sheets are fed from the cutter to a primary conveyor on which they are spaced apart, and then to a secondary conveyor driven at a slower speed so that the sheets are overlapped, and finally fed onto the top of a stack. In one arrangement a pair of rollers, between which the sheets are gripped, is positioned between adjacent ends of the primary and secondary conveyors, which rollers are driven at a speed which is cyclically variable between the speeds of the two conveyors so as to decelerate the sheets. In another arrangement the secondary conveyor is dispensed with and the sheets are fed directly onto the stack from the variable speed rollers.
    • 在用于将纸幅切割成片材并将其形成为堆叠的机器中,片材从切割器进给到它们间隔开的主传送带,然后到较慢速度驱动的二次传送器,使得片材 重叠,最后馈送到堆叠的顶部。 在一种布置中,一对辊被夹在其间,位于主输送机和次输送机的相邻端之间,这些辊以两个输送机的速度之间可循环变化的速度被驱动,从而使 床单。 在另一种布置中,省去了二次输送机,并且片材从变速辊直接供给到堆叠上。

    • A machine for broaching external gears comprising a frame, a pot broaching tool positioned with its axis vertical at the upper portion of the frame, a piston and cylinder device with its axis vertical located directly beneath the pot broach. The gear blank is positioned directly above a work support carried by the piston and is pushed upwardly through the pot broach to a position of clearance above. The cutting teeth of the broach are of course directed downwardly and each cutting tooth has a chip receiving space directly beneath it into which chips are formed during the broaching operation and from which chips are displaced for downward discharge.
    • 一种用于拉削外部齿轮的机器,包括框架,其纵轴垂直于所述框架的上部定位的罐式拉削工具,其轴线垂直定位在所述锅刀的正下方的活塞和气缸装置。 齿轮坯料直接位于由活塞承载的工件支承件的正上方,并被向上推动通过锅刀到上方的间隙。 拉刀的切割齿当然被向下引导,并且每个切割齿具有直接在其下方的切屑容纳空间,在拉削操作期间切屑形成在其中,并且芯片从中移出以向下排出。
