Compression apparatus including a press framework defining a compression region for housing material such as straw to be compressed, one or more compression elements such as two opposed arrays of compression teeth for compressing material by movement along the compression region, and a drive mechanism for moving the compression teeth in a cycle of movement. The cycle includes the compression teeth entering into the compression region, moving along the compression region along a substantially rectilinear path to compress material in the compression region, and returning to the position occupied at the beginning of the cycle, the compression teeth being at least partially removed from the compression region during the return movement. Preferably the material to be compressed is preformed into a column of material fed continuously into the compression region, the compression teeth being arranged to sever a portion of the column, to compress the portion, and to execute the return movement by moving past the preformed column while it continues to move into the compression region.
