A method and apparatus for forming a container from a sheet of blank material, whereby a segmented male die member first forms the bottom and then the sidewall and rim of the container prior to the formation of the lip portion of the container while the blank is being restrained in a radial direction by the engagement of the blank by two opposing draw pad members.

Method and apparatus for forming paperboard containers

A device for aligning an elliptical blank relative to a female die half comprising a drawpad having an elliptical opening supporting a blank in position on a female die half. Alignment pins are movable rearwardly of the minor diameter of the blank within slots formed in the drawpad for engaging the perimeter of the blank for rotating the blank to the aligned position, in preparation for press forming the blank into the desired shape.

Apparatus and related method for aligning irregular blanks relative to a

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.
