Abstract
The invention relates to an apparatus and a method for producing a plurality of liquid threads and droplets in order to record information on a moving data carrier, whereby a film of liquid is produced on an inclined cascade outlet face, the film is broken up into liquid threads, the liquid threads are broken up into droplets which fall vertically downwards in free fall and the droplets which are unwanted for information are separated and fed to a collector.
Claims16
A method of producing multiple liquid threads and liquid droplets for recording information on a data carrier, characterised in that
- (a) The recording liquid for producing the liquid threads flows out of at least one feed slit in the upper portion of an inclined cascade outlet face,
- (b) the liquid flows as a film over the outlet face and, in so doing, homogenises into a film,
- (c) the homogeneous liquid film is broken up into liquid threads in the lower region of the entire width of the cascade outlet face,
- (d) the liquid threads are broken up into droplets,
- (e) the droplets fall vertically downwards in free fall parallel to each other,
- (f) the droplets which are unwanted for information are separated and fed to a collector,
- (g) and the droplets which are required for information impinge upon a data carrier, the data carrier being moved beneath the curtain of falling droplets.
