The fully auto right angle paper feeder and stacker works to automatically stack, convey and collect cardboards whose maximum length is 2,300mm. The cardboards are horizontally output. The vertically collected cardboards are transmitted with the wide conveyer belt. As soon as the number and height of the cardboard reach required levels, the cardboard will be moved out by use of the control switch.

The location of the fully auto right angle paper feeder and stacker in the WJ computer high speed corrugated cardboard production line is shown in the diagram (12) and that in the HS high speed corrugated cardboard single sheet production line is illustrated in the drawing ⑥.
