ABSTRACT:
A method and apparatus for unpacking a box packed with compressed material. The method comprises the steps of placing a box packed with compressed material and having flaps at a bottom thereof on a bed having an opening therein, lifting said box from said bed to allow said compressed material to start descending from within the box thereby causing said flaps to open gradually, raising a support member from said opening through said opened flaps to support said compressed material from below, continuing said lifting of the box until the flaps completely open, and lowering said support member to place said compressed material on said bed. The apparatus comprises an unpacking section having a bed, feed-in conveyor means to feed a box packed with compressed material and having flaps at a bottom thereof to said unpacking section, lift means provided above said unpacking section for lifting said box to allow said compressed material to start descending from within, and feed-out conveyor means to receive said emptied box from the unpacking section and feed out said emptied box from the apparatus.
