    • A multi-ream paper sheet feeder (21) for use with high speed copiers, printing machines and the like "host machines" (27) has a sturdy frame (22) supporting an upwardly sloping ramp (29) overlying a motor driven feed screw (57). A pusher plate (47) drives a feed block (31) of as many as thirty reams of edgewise stacked paper sheets up the ramp to a singulating feed assembly (24,105). A feed screw drive nut carriage (51) engages and drives the pusher plate up ramp, then disengages, retracts under the ramp and travels to a new start position at the ramp's lower end. Sensors and limit switches (87,88) govern forward and reverse feed screw motor (M) operation; another sensor governs the operation of the singulating feed assembly (24,105), delivering shingled sheets on demand to the feeder's infeed tray (26). The entire sheet feeder is track-mounted, latched in feed position, disengageable for retraction away from the host machine when desired.
    • 与高速复印机,印刷机等“主机”(27)一起使用的多令纸送纸器(21)具有一个坚固的框架(22),该框架支承一个向上倾斜的斜坡(29),该斜坡(29)覆盖在电动机驱动的进给螺杆 (57)。 一个推板(47)将多达三十个沿边堆叠的纸张向上送入一个单独供给组件(24,105)中的进料块(31)。 进给丝杠驱动螺母滑架(51)接合并驱动推板上坡道,然后脱开,在坡道下方缩回并行进到坡道下端的新起始位置。 传感器和限位开关(87,88)控制正向和反向进给螺杆马达(M)的运行; 另一个传感器控制分拣供给组件(24,105)的操作,将需要时的搭叠纸张传送到供给器的供给盘(26)。 整个送纸器都是轨道式安装的,锁定在送纸位置,在需要时可脱离以便从主机收回。
