ABSTRACT:
The invention is an automatic, unmanned, powered, variable speed transfer table for a finger joint machine which receives a controlled supply of blocks from a lineal block feeder. The slat chain is composed of two chain loops, connected at regular, equal intervals by slats. The slat chain pushes blocks over an even ending conveyor which aligns them to the inside of one of the chains and then over a moisture detecting system. Blocks containing unacceptable moisture fall through a gap in the working table while blocks with acceptable moisture are pushed by the slats over a door covering the gap and onto an outfeed table. The slats are synchronized to the lugs on the finger joint machine's lug chain and deposit correctly aligned and orientated blocks precisely on the lug chain. The slat chain then rotates upward and loops back over the working table and then down, under the infeed conveyor to re-emerge at the even ending conveyor.
