Abstract
A heated blade arrangement in a press is brought down on a plastic work piece of heavy corrugated plastic held on the bed of the press to compress the work piece along fold lines. The work piece may then be folded up to form a box-like structure. The arrangement includes heaters to heat surfaces of the work piece to be pressed together for adhesion. A frame is provided, about which the box-like structure may be formed.
