Apparatus and method for corona discharge priming a dielectric web |
摘要 |
A dielectric web substrate is primed for adhesion of a plastic coating by passing between two rolls in rolling contact therewith. One roll has a conductive core and an insulating jacket while the other roll has a conductive surface. A high voltage A.C. source is connected between the conductive portions of both rolls to establish a corona discharge therebetween to effect said priming. Additional rolls with conductive surfaces may be connected in parallel with the first such roll.
