In a printing machine or the like wherein sheets are delivered seriatim into a receiving tray whereat the sheets come to rest by gravity onto a stack in the tray, a device for facilitating stacking the sheets into the tray at high speed. Each sheet is directed from the machine in a path outwardly over the tray. Guide surfaces act against a lead end of the sheet to prevent upward escape of the sheets from the path. A deflecting mechanism diverts each sheet downwardly into the tray to clear the path for a succeeding sheet. A stop plate is provided beneath the deflecting mechanism for acting against a trail end of each sheet to control and guide the sheet into alignment onto the stack in the tray.

Sheet stacking device

A sheet unloading device for use in a printing or duplicating machine, or the like, wherein sheets are delivered seriatim to a receiving tray whereat the sheets are deposited onto the top of a stack of sheets in the tray. An interposer mechanism is movable to an operative position at the end of the tray for dividing the tray into a first, lower portion and a second, upper portion. The interposer mechanism permits removal of the lower portion of the stack while sheets are continuously delivered to the upper portion of the stack. A back stop is provided at the end of the tray and can be selectively lowered to permit removal of the lower portion of the stack of sheets.

Sheet unloading device

A mechanism for registering sheets in a printing or duplicating machine which includes a conveyor board for delivering the sheets seriatim to the registering mechanism. A stop guide is mounted on a fixed support of the machine at one side of the conveyor board. A jogger guide is mounted on a jogger device of the machine at the opposite side of the conveyor board. The jogger guide includes a spring loaded blade for acting against a side edge of the sheet to move the sheet laterally to engage an opposite side edge of the sheet against the stop guide. The spring pressure of the blade is adjustable to accommodate sheets of varying weight, and the blade is provided with floating movement to accommodate sheets which are skewed or out-of-square. A calibrated dial is employed for incrementally adjusting the location and spring pressure of the blade. The stop guide and jogger guide are easily converted for left hand or right hand jogging, or vice versa, without removing either guide from the machine.
