Abstract: A pressed paperboard container (10) is formed having a bottom wall (11), an upturned side wall (12), and an overturned rim (13 ) extending from the side wall which is denser and thinner than the rest of the container. The container is formed by pressing a flat circular blank (27) between upper and lower dies (25, 26) having die surfaces (31, 32, 38, 39, 40) which shape the blank into proper form, and the surfaces of the dies (25, 26) at the rim area (13) of the container are shaped to exert extremely high compressive stresses on the rim, particularly at the folded areas (20) formed in the rim during initial shaping of the container. The high compressive stresses applied to the rim area, along with proper moisture levels maintained in the paperboard and the heating of the paperboard by the heated dies, causes the paperboard in the rim area to deform plastically, densify, and fill in voids created as the blank was pressed into the container form. The integral, dense rim is a rigid structure which provides resistance to bending to the entire container.
Abstract translation: 压制的纸板容器（10）形成有具有底壁（11），向上的侧壁（12）和从侧壁延伸的翻转的边缘（13），其比容器的其余部分更致密和更薄。 通过将具有将坯料成形为适当形状的模具表面（31,32,38,39,40）的上模具和下模具（25,26）之间的平面圆形坯料（27）压制而形成容器， 在容器的边缘区域（13）处的模具（25,26）被成形为在轮缘上施加非常高的压缩应力，特别是在容器的初始成形期间形成在边缘中的折叠区域（20）处。 施加到边缘区域的高压缩应力以及纸板中保持的适当的水分含量以及加热模具对纸板的加热使得边缘区域中的纸板塑性变形，致密化并且填充如下形成的空隙： 空白被压入容器形式。 整体密实的边缘是刚性结构，其对整个容器的弯曲提供阻力。

Abstract: An apparatus and method for automatically forming at least two sheets of material into an article, such as a flower pot cover, is provided. The apparatus includes a first roll of sheet material, a second roll of sheet material, a female die and a male die. A first sheet of material and a second sheet of material are automatically formed from the first and second rolls of sheet material, respectively, and the first and second sheets of material are positioned between the male die and the female die. The male and female dies are shaped such that at least a portion of the male die is receivable in the opening of the female die to form the article. The formed articles are automatically stacked.

Abstract: A method and apparatus for forming a double-thickness bead in a flexible sheet stock article, such as a container or lid constructed from paper stock. The method includes holding a central region of the paper stock blank near its perimetral edge between cooperating dies, forming an axially extending flange in the blank between the held region and the edge, capturing the edge against radial movement in a groove provided in a ring movable relative to the dies, and moving the ring relative to the dies to form the double-thickness region in the blank between the held portion and edge. The apparatus includes the cooperating relatively movable dies, the movable ring and cooperating draw pads adjacent the ring. The draw pads are movable relative to the dies and ring and cooperate with the dies and ring to form a void into which the double-thickness region is formed. The configuration of the void controls the formation and configuration of the bead.
