Abstract: Apparatus for stacking and compressing batts of compressible material comprising a vertical stacking chamber, indexing gates in the upper portion of said stacking chamber normally disposed to receive batts, an indexing and compression plate, means for repeatedly cycling said indexing and compression plate around a first path a predetermined number of times and then around a second path once, said first path extending upwardly of the outside of said stacking chamber laterally into said stacking chamber at a level above said indexing gates, downwardly in said stacking chamber, through said indexing gates, and laterally out of said stacking chamber, said second path extending upwardly of the outside of said stacking chamber, laterally into said stacking chamber, downwardly in said stacking chamber to a compression level in the lower portion thereof that is below the extent of downward travel of said first path and laterally out of said stacking chamber, said indexing gates being operable in response to the passa
