ABSTRACT:
An electrostatic charging system holds a film web to a roll without significant slippage, thus allowing for proper tension control of the web even with extreme differences in tension upstream and downstream of the motorized roll. The system can electrostatically transfer a web using motorized drum rolls with an internally integrated web severing knife.
