Bottom sealing assembly for cup forming machine

A bottom sealing station for a paper cup forming machine, the bottom sealing station comprising:

• a forming tool rotating in a circle having a first radius, the forming tool being adapted to be moved to rotate in a circle having a second radius that is larger than the first radius, and a controller operably connected to the forming tool to electronically provide for electronically adjusting the second radius.

A bottom sealing station for a paper cup forming machine, the bottom sealing station comprising:

• a linear motion assembly, a forming tool adapted to be rotated in a circle, and a controller electrically connected to the linear motion assembly, wherein the linear motion assembly moves the forming tool between an extended position and a retracted position, and wherein the controller electronically adjusts the extended and retracted positions of the forming tool.

A bottom sealing workstation for a cup forming machine having a main turret and a plurality of mandrels thereon arranged to interact with a plurality of workstations, each mandrel being configured to receive a sidewall blank and a bottom blank that are subsequently manipulated at a plurality of workstations to form a cup, the bottom finishing workstation comprising:

• a first motor mechanically connected to a linear motion assembly of the bottom sealing workstation to linearly move the linear motion assembly toward a mandrel;
• a second motor mechanically connected to a rotation assembly of the bottom sealing workstation to rotate a forming tool in a circle having a radius;
• and, a third motor mechanically connected to the forming tool to adjust the radius of the circle in which the forming tool rotates to any of a variety of radii.
