  • Bottom sealing assembly for cup forming machine
    Patent number: 7121991
    Abstract: A bottom sealing workstation is provided for a cup forming machine. The bottom sealing workstation has a linear motion assembly, a rotation assembly, a phase change assembly. A first motor is 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 is 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 is mechanically connected to the phase change assembly to adjust the radius of the circle in which the forming tool rotates. Additionally, a controller may be electrically connected to the bottom sealing workstation to send electronic signals to the first and third motors to quantitatively control various assemblies of the bottom sealing workstation.
