ABSTRACT:
An apparatus is provided for pretreating plastic sheets having poor adhesive properties, with a primer treatment. The primer treatment includes a sheet conveyor for conveying plastic sheets in one direction at a constant speed. A flexible, porous friction member is arranged so as to come into contact with adhesive areas of the plastic sheets. A press confronts the friction member and presses the plastic sheet against the friction member. A primer solution is supplied to the friction member where it is transmitted to the plastic sheet.
