Figure 9. Paper face-down in the gathering area
See
to
• When the paper enters the gathering area, a clamp on the rotating drum grips
the lead edge of the sheet.
• The paper is flipped upside down to ‘face-down’ orientation, released and
knocked-up against the endlay on the same side as the infeed. The opposite
endlay has an inbuilt side-tamper to assist with the knock-up.
• In the gathering area, the paper is placed between the endlays and sidelays. The
endlays and sidelays are adjusted by the PSQ160 to the measured paper-size
entered into the touch screen. Adjustments to the sidelays and endlays are
made with stepper motors.
See
• An active tamper gate in the front sidelay jogs the incoming sheets into a tidy set.
When the set is complete, the active tamper gate lifts to let the set move to the
staple position. The active gate is driven by a stepper motor.
• Optical sensors in the infeed, the gathering area and in the tumbler see when
paper is present. If the time between the operation of the sensors is too long or if
a sensor remains covered, then a flow error or paper jam in the gathering area is
indicated.
