Abstract: An apparatus for forming an upper edge of a paperboard container includes a pocket including a shell having a cavity with a mouth configured to receive the container along an axis such that the rim extends beyond the mouth. A workstation includes a forming member having a first forming surface which is actuatable toward the axis from a retracted position spaced from the rim to an extended position lying adjacent an upper end of the rim, and a forming segment having a second forming surface which is actuatable along the axis and the forming member in response to axial movement thereof such that the second forming surface is positioned spaced from a lower end of the rim. The second forming surface is actuatable along the axis towards the first forming surface to form the rim therebetween.

Abstract: An automated cup making system is provided for forming a two stage cup having an upper cup disposed upon a lower cup. An upper cup making machine is provided for forming an upper cup having an upper cup sidewall and an upper cup bottom wall disposed generally transversely to the upper cup sidewall and punched out to define a bottom wall annular border extending radially inwardly from the upper cup sidewall, the upper cup sidewall having an outwardly curled top edge. A lower cup making machine is provided for forming a lower cup having a lower cup sidewall and a bottom cup wall disposed generally transversely to the lower cup sidewall, the lower cup sidewall having a curled top edge.

Abstract: A machine and a method for forming a rim of a paperboard container having a bottom and a sidewall terminating at a rim are disclosed. The machine includes a frame, a turret rotatably coupled to the frame, a plurality of circumferentially spaced pockets supported by the turret and a plurality of workstations about the turret. Each pocket includes a shell having a cavity with a mouth configured to receive the container along an axis and a first member about the cavity and including a first surface. The first surface is one of a flat surface and a concave surface and is actuatable along the axis from a retracted position below the mouth to an extended position adjacent the mouth. The plurality of workstations includes a first station and a second station. The first station has a first tool with a second surface, wherein the second surface is said one of a flat surface and a concave surface.

Abstract: A machine for securing a thermoplastic coated paper handle to a paper cup, the machine including a mandrel turret mounted for rotary motion on a frame, the turret including a plurality of mandrels and a pair of clamp assemblies for clamping the cups onto the mandrels, a die assembly mounted on the frame for stamping paper handles from a strip of thermoplastic coated paper and a transfer turret for transferring the paper handles from the die assembly to the mandrel turret for attachment to the cups.

Abstract: A machine for securing a thermoplastic coated paper handle to a paper cup having a seam on one side of the cup, the machine including a die assembly for forming paper handles having a backing strip and a wing on each side of the strip, a mandrel turret having a number of mandrels spaced about the perimeter of the turret, each of said mandrels having a blade assembly projecting outwardly from the surface of the mandrel to engage the seam in the cup, and a wheel assembly for rotating the cups on the mandrel to move the seam in the cup into engagement with the blade assembly, and a transfer turret for transferring the paper handles from the die assembly to the mandrel turret for attachment to the cups.
