Abstract
Cleaning of a product in strip or sheet form. The device is characterised in that: the electrode is enclosed in an insulating housing (20) connected to the said channel by an antihalo duct (30), the housing is swept by a weak flow of air, so as to carry away the ions on the moving strip. Application to unexposed photosensitive products.
Claims8
An apparatus for cleaning a strip of unexposed photosensitive product, including;
- a channel through which the strip can run in one direction of movement;
- a treatment area established transversely to the direction of running of the strip and over the entire width of the strip, the treatment area including means for sweeping both surfaces of the strip with a curtain of air flowing in the opposite direction to the strip;
- at least one elongated electrode having a tip and an axis, being connected to a high potential in order to produce local ionization by corona effect;
- an insulating housing defining a chamber wherein the electrode is enclosed, the housing being connected to said channel by an angled antihalo duct;
- and means for supplying compressed air to said chamber through at least one inlet duct in order to carry away ions from the electrode to the moving web through the antihalo duct, said at least one inlet duct being an elongated cylinder, the axis of which intercepts the axis of the electrode in the vicinity of its tip.
