Abstract: 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.

Abstract: An apparatus having a male mold, a female mold and plurality of fingers suspended about the male mold for controlling a sheet of material being formed into a flower pot or flower pot cover. The female mold has a female opening defining a female forming surface. The male mold, in turn, has an outer periphery defining a male forming surface which mates with the female forming surface. The fingers are adapted to telescope in relation to the male mold. With a sheet of material over the female opening and the fingers in the lower position, the male mold is moved into the female opening to form the sheet of material into a flower pot or flower pot cover. The fingers engage and control the sheet of material and telescope with respect to the male mold as the male mold is moved into the female opening.

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: A press for forming sheet material into a shaped article comprising a frame, first and second complementary dies, a cam supported by the frame for reciprocally moving the first die along an axis between a first position axially spaced from the second die and a second position fully mated with the second die, the cam including a dwell period when the first die is in the second position. The press includes a bolster supporting the second die for axial movement between upper and lower limits, the bolster being axially spaced from the upper limit by movement of the first die to the second position. The press also includes a hydraulic power circuit responsive to the position of the cam for normally biasing the bolster toward its upper limit under a first hydraulic pressure and for biasing the bolster toward the upper limit under a second hydraulic pressure during the dwell period, the second hydraulic pressure being greater than the first hydraulic pressure.

Abstract: A method and apparatus are disclosed for imparting a desired shape to a paperboard blank. The blank is formed between two dies for a sufficient length of time and with sufficient force to set the form, while moving the dies in tandem along a predetermined portion of a reciprocation path. Because the formed blank remains in dwell while the dies are moving in tandem, it is not necessary to hold the dies stationary to ensure permanent formation of the blank. This allows greater production speeds.

Abstract: 本発明は、シート材料のブランク(2)からトレイ(1)を深絞りする方法及び装置に関する。ブランクには、加工中に形成される皺の位置を決定するスコアラインが設けられる。装置は、トレイの底を外面側から形成するためのキャビティ(7)を備える雌成形型(3)と、トレイを形成するためのキャビティに対して移動可能な、トレイの底を内面側から形成するためのプランジャー(11)を備える雄成形型(4)と、シート材料を保持し、トレイの周縁フランジ部を形成するための接触面を有するクランプ(6、15)とを備える。本発明によれば、成形型(3、4)のうちの少なくとも一方をシート材料から側方に離間して設けることによって、自由形成のための空間を設け、その結果、トレイ側壁における皺の発生が、制御された形で実現される。プランジャー(11)の位置を、雌成形型(3)のキャビティ(7)と相対的に調整するために、スペーサープレート(13)を、プランジャー(11)の後部に配置できる。キャビティは、独立した底板(8)と、その下にスペーサープレート(9)を有することができ、又はキャビティの底の、クランプの接触面からの距離を調整するためのネジ手段を設けることができ、それによってトレイの深さを変化させる。
