  • Patent number: 4548393
    Abstract: A stopping mechanism in an inserting machine having a feeder for feeding documents seriatim to a transport deck therebelow, the feeder being angled with respect to the deck. The stopping mechanism stops the documents at a predetermined position with respect to a previously collated package situated on a ramp located upstream of the deck and elevated with respect to the deck. The stopping mechanism comprises a pivotable paddle located downstream of the feeder substantially parallel to the direction of feed, a device for biasing the lower end of the paddle away from the transport deck to permit a collated package to pass therebelow without contacting the pivotable paddle, and a device for pivoting the lower end of the paddle downward adjacent the transport deck for a short period of time at an appropriate moment in order to stop the forward motion of a document exiting the feeder at a predetermined position on the transport deck.

  • Patent number: 4073391
    Abstract: A sheet jogger to justify and align a stack of sheets into a registered bundle which is subsequently discharged into a bin. Prior to discharging of the bundle, the stack of sheets can be stapled. Each bundle is offset from every other bundle when discharged into the bin. Sheets are fed onto a jogging deck by at least one conveyor roller to abut against at least one gate finger at the end of the jogging deck. A back jogger aligns the sheets into registration against the gate finger and a left side jogger assembly jogs the sheets into alignment against a right side jogger assembly. The gate fingers drop down and a lower eject roller rises above the jogging deck to engage a bottom sheet of the stack thereby engaging the stack against an upper fixed pressure roller.
