摘要： A polymer film producing apparatus includes a casting device, having a casting die, for ejecting dope to form a bead, and casting the bead on a support drum traveling continuously to form a cast film, the dope containing polymer, solvent and additive. A dryer dries the cast film stripped from the support drum, to obtain a polymer film. A voltage application device is connected with the support drum, for applying voltage to the support drum during casting of the casting device. Preferably, the support drum is electrically non-grounded, and has a surface coated with an electrical insulation film. A surface potential V of the support drum is in a range of 0.1 kV

摘要： In general, the step-like unevenness due to the fluctuation in the sheet-shaped molten resin in the vicinity of the surface of the cooling support remains as it is as thickness unevenness without undergoing leveling because the sheet-shaped molten resin is cast on the cooling support immediately after generation of the fluctuation to be solidified by cooling. However, according to an aspect of the present invention, the vibration of the sheet-shaped molten resin in the vicinity of the surface of the cooling support is specified to be 10 dB or less, and accordingly, the fluctuation of the sheet-shaped molten resin in the vicinity of the surface of the cooling support is suppressed and the sheet-shaped molten resin sufficiently undergoes leveling on the cooling support. Consequently, the generation of the continuous and periodic step-like thickness unevenness along the lengthwise direction of the sheet-shaped molten resin can be prevented.

摘要： Automotive trim strips (32) are made by extruding a thermoplastic material onto a foil carrier (24). The foil carrier (24) has a receiving surface having a low strength adhesive for releasably receiving the thermoplastic material (22). The thermoplastic material is end formed to contour ends of the thermoplastic material such that an automotive trim strip (32) is formed having a predetermined final length. The automotive trim strips (32) are then cooled. The foil carrier (24) is removed presenting a substantially flat surface for receiving adhesives for permanently attaching the automotive trim strip (32) to the vehicle.
