ABSTRACT:
An antistatic roll is provided for use in transferring and/or winding a continuous sheet of polymeric film. The roll comprises a cylindrical core made of an electrically conductive material which is provided with a pair of rotational shafts, each extending away from the opposite ends of the roll in an axial direction. A layer of dielectric material surrounds the core, which has a spiral groove formed on the outer circumference thereof at a substantially equal pitch. An elongate conductor is held within and extends along the spiral groove to gather static electricity from the roll and/or the polymeric film. Associated with the elongate conductor is a grounding arrangement to drain off the static electricity gathered therein.
