ABSTRACT:
A system for stacking veneer sheets conveyed from two different directions includes a lower mechanism for carrying a first veneer sheet to a first position above a stack support and an upper mechanism for carrying a second sheet to a second position above the first position. The first veneer sheet carried to the first position may not be dropped immediately, but waits for the second veneer sheet to be dropped thereon from the second position, and then the first and second veneer sheets may be dropped as one body on the stack support. The lower carry mechanism includes a carry roller and a sheet carrier which may be moved substantially synchronously. However, the sheet carrier is moved through a stopper away from the carry roller when the veneer sheets are to be freed from the support thereof by the sheet carrier.
