PCT No. PCT/JP91/00782 Sec. 371 Date Apr. 6, 1992 Sec. 102(e) Date Apr. 6, 1992 PCT Filed Jun. 11, 1991 PCT Pub. No. WO91/19576 PCT Pub. Date Dec. 26, 1991.It is an object of this invention to provide a transfer feeder wherein lift levers are pivoted to vertically move upstream and downstream lift beams through connecting rods and lift mechanisms to change their heights, and cross bars extend between transfer bars and are adapted to adjust the level of a workpiece to a plurality of different levels. The transfer feeder comprises a first feed height adjustment mechanism (25) disposed between the lift levers (22) and the connecting rods (28) to simultaneously change the height of the upstream lift beams (71) and the downstream lift beams (72) to respective levels, and a second feed height adjustment mechanism (30) disposed between the lift mechanisms (8) for the upstream lift beams (71) and the lift mechanisms (8) for the downstream lift beams (72) to change the height of the upstream lift beams relative to the upstream lift beams.
