STICKER POSITIONING APPARATUS FOR USE WITH LUMBER STACKER ABSTRACT OF DISCLOSURE Apparatus is disclosed for accurately positioning stickers when stacking lumber. The apparatus provides an unscrambling conveyer that feeds stickers from a bulk supply to a crowder feed conveyer that presents a constant supply of stickers to a timed release mechanism. The release mechanism by cam means sequentially presents individual stickers in a timed fashion to an endless distribution conveyer that initially feeds the stickers through a first upper horizontal feed plane, thence about a curved guide structure, and finally about a second horizontal feed plane below the first feed plane. The stickers are maintained in the second feed plane by an underlying bottom shelf structure. The bottom shelf structure feeds individual stickers into a plurality of spaced sticker positioners that oscillate from an upper position downwardly to a lower position to feed the stickers onto the top of a lumber stack to accurately position them in spaced relation to the stack of lumber therebeneath.
