Flexible media stacking and accumulating device

A method for a stacker apparatus capable of stacking flexible media of varying dimensions in any of a plurality of orientations, comprising:

• transporting the flexible media to a carriage;
• translating the carriage to unwrap a first membrane from a first rotating member and to fold the leading edge of the media onto a stack;
• wrapping a second membrane about a second rotating member of the carriage;
• gripping the media between the first membrane and the stack as the carriage moves to stack the media;
• translating the carriage in the opposite direction after the media has been stacked;
• and
• gripping the media between the second membrane and the stack as the second membrane unwraps from the second rotating member.

An apparatus capable of stacking flexible media of a plurality of dimensions, comprising:

• a container for storing the flexible media;
• a carriage movably mounted on the container, the carriage having at least two rotating members;
• and
• a membrane wrapped about each of the rotating members.
