ABSTRACT:
Disclosed is a method and apparatus for pressing and binding voluminous material into bales, in which material in the form of several layers is supplied through a closable opening into a pressing chamber where compression takes place of each supplied layer. Final pressing is carried out at high pressure after a desired number of layers have been supplied into the pressing chamber, whereafter the pressing effect is lowered to a substantially lower pressure, so that the material compressed into a bale is permitted to expand, and the bale thereafter is discharged from said pressing chamber through a closable opening and bound while said substantially lower pressure is being maintained.
