A method and apparatus for enhancing the lamination of two plastic films on a rotating embossing roll or other roll. Two films are extruded and brought into contact on the rotating roll. An electrode and power supply generate an electrostatic field to press the outer plastic film into intimate contact with the inner plastic film. The electrode is positioned in a spaced apart relation from the roll where the two plastic films are brought together. The electrode may be positioned in a protective housing. Positive air pressure may be maintained in the housing to reduce the accumulation of smoke and contaminants on the electrode. The electrode may also be positioned on retractable mount which allows the electrode to be retracted from its normal operating position and readily cleaned. |
