发明名称 Tray-forming process and apparatus
摘要 A process and apparatus for forming three-dimensional containers from a continuous flat web of paper, coated paper, paper board, or laminated paper board ("paper") in which the paper is first scored to define the shape of the container and, thereafter, the scored stock is simultaneously cut and formed into a container. Containers so produced have improved uniformity. The apparatus is less expensive and easier to operate than conventional equipment, and it is easier to change from one style of tray to another. The apparatus also makes possible tray styles which could not be made with machines which cut and transfer paper blanks to a separate forming station.
