Abstract
The present invention provides for a method and apparatus for automatically lining a container having at least one open end. A bag-type liner having a sealed and unsealed end is suspended in the container with the sealed end down. A plurality of clamps grab the sides of the bag and open the unsealed end by pulling the sides apart. Air is then withdrawn from between the liner and container thereby expanding the liner in the container. If the container has two oppositely facing open ends, a vent can be positioned under one of the open ends for drawing air out from the container. If the container has only one open end, a plurality of vacuum robes can be inserted at the four corners of the container between the liner and the container for drawing air out from between the liner and container.
