Patent ID: 8287267

Claim:
A sheet forming apparatus configured to obtain a formed product in a sheet shape by cooling and solidifying molten resin, comprising: a first roll configured to rotate relative to a frame; a second roll configured to rotate relative to the frame and to sandwich sheet-shaped molten resin extruded from a die in cooperation with the first roll; first and second coupling members, each coupling member having a proximal end side supported by any of the frame and the second roll, the first and second coupling members being provided to be revolvable, relative to any of the frame and the second roll, around a rotation center axis of the second roll, the first coupling member being provided on one end side of the second roll and the second coupling member being provided on another end side of the second roll; a coupling member revolution positioning unit having a coupling shaft member configured to synchronously revolve and position the first and second coupling members by applying a torque to the first and second coupling members at an intermediate part or on a distal end side of the first and second coupling members; a third roll provided on the distal end side of the first and second coupling members so as to be rotatable relative to the first and second coupling members, the third roll configured to revolve around the rotation center axis of the second roll by way of revolution of the first and second coupling members and to sandwich the resin in cooperation with the second roll, the resin conveyed along an outer periphery of the second roll by rotation of the second roll after being sandwiched between the first roll and the second roll; and first and second coupling member supporters configured to support the first and second coupling members at an intermediate part or on the distal end side of the first and second coupling members so as to allow the first and second coupling members to revolve relative to the frame.
