ABSTRACT:
A veneer stacker for receiving sheets of veneer at a relatively high rate of speed and assembling them into a uniform stack. The stacker utilizes the velocity of the veneer sheet, acting against a series of curved guide shoes, for supporting the sheet by means of centrifugal force, while guiding it to a stacking position. As the sheet approaches the stacking position, it initiates a momentary vacuum braking action adapted to draw the sheet into intimate engagement with the guide shoes, stopping the sheet, thereby removing its supporting force. Continuously rotating vacuum drums engage the lead edge of the falling sheet for positioning it against an aligning forward stop, and correcting skew of the sheet as an incident to such positioning.
