  • Patent number: 5118374
    Abstract: The outer surface of the base of a heated C channel is brought to bear against the surface of a laminate to be bent about and adhered to the curved edge of a substrate by pivoting a frame pivotally attached to a substrate supporting platform. A torque tube supports the C channel to inhibit bending and twisting of the C channel. A plurality of pairs of pneumatic cylinders extend from the frame to urge the torque tube and attached C channel toward the curved edge and to maintain the base of the C channel in progressive tangential contact with the point of attachment of the laminate to the curved edge while minimizing sliding movement between the base of the C channel and the laminate.
