    摘要: A machine for forming open ended cartons from flat die cut blanks of flexible material. The machine includes a magazine adapted to contain a supply of the blanks, and first, second and third forming stations through which the blanks are successively shifted by automatically operable transfer mechanisms. The blanks are progressively folded as they progress through the forming stations. At a final stage in the forming process, adhesive is selectively applied to the undersides of exposed side flaps, and these side flaps are then folded to produce the desired end product. At various stages during the forming process, the partially erected blanks are supported both internally and externally in order to avoid deformation or collapsing of open ends, and to insure precise bending along fold lines.
