ABSTRACT:
A device for supplying a film which possesses an electrically conductive layer which can be grounded is described which is composed of a spool mountable on a rotatable grounded spindle; retaining means for securing the trailing edge of an electrically conductive film wound on the spool; means for electrically connecting the spool to the grounded spindle and contact means mounted on the trailing edge of the film so as to maintain electrical contact between the conductive layer of the film and the conductive means during unwinding of the film from the spool. The device allows the continuous unwinding of the spool while maintaining a simultaneous ground connection between the conductive layer of the spool and a ground.
