Abstract

A control device for use on film cleaners that remove dust, lint and static charge from plastic film surfaces by the use of high velocity ionized air. The high velocity ionized air removes static charge from the film simultaneously as the dust and lint are blown from the surface of the film by the convective action of the air. The control device is automatically activated when film is inserted between two sets of intersecting conductive fibers, thereby breaking the contact between the two sets of conductive fibers. In addition, the control device can be switched between a constant mode, where the air is on continuously, to a pulse mode where the air is pulsed alternately on and off, in a periodic manner, to synchronize the cleaning action with the stop and go advance of an automatic film printer system. The intersecting fibers also prevent the film from being drawn into the air inlets by the 'Bernoulli Effect'.
