- the intermediate after performing the electropolishing process and preferably after passing through the further cleaning device with an appropriate preservation device with a Rust preventive is preserved, which is why the intermediate the preservation device also expediently goes through, so as to work continuously receive.
- the sawtooth wire when performing this procedure continuously from a decoiler is withdrawn, then first to Implementation of a mechanical cleaning designed cleaning device passes through, then the electrolyte bath passes through, being essentially helical in the electrolyte bath circulates in order to achieve a long dwell time another cleaning device after leaving the electrolyte bath to remove electrolyte residue, then goes through a preservation facility to subsequently submitted to a take-up reel and wound up on it be, the conveyor required for this purpose between the conservation facility and the The reel is arranged and has two conveyor rollers, between which the intermediate product is clamped.
- the device shown in the drawing consists in essentially from a decoiler 10 on which a wire-shaped Intermediate product in the form of a saw tooth provided wire is wound, one for carrying out mechanical cleaning of this intermediate product Cleaning device 20, an electrolyte bath 30, one for rinsing the intermediate product leaving the electrolyte bath designed further cleaning device 40, a preservation device 50, a conveyor 60 and a take-up reel 70.
- the conveyor 60 comprises two parallel to each other conveyor rollers 62 and 64 having running roller axes, between which the intermediate product is clamped. Go berserk of the conveyor rollers 62 and 64 in the in the drawing The arrows P indicated directions become the sawtooth wire 5 in the direction indicated by arrow P 'from the unwinder 10 deducted.
- the sawtooth wire 5 is first with a guide roller 12 deflects a substantially horizontal path and then introduced into the cleaning device 20.
- this Cleaning device 20 is the sawtooth wire with two cleaning rollers 22 and 24 mechanically cleaned, instead of the cleaning rollers also brushes and / or slurry disks can be used.
- the sawtooth wire 5 in the course of the Conveyor 60 caused funding in the direction of funding Electrolyte bath arranged behind the cleaning device 20 30 introduced.
- the sawtooth wire circulates within the electrolyte bath 30 5 essentially helical two parallel to each other running roller axes and within the electrolyte bath 30 arranged deflection rollers 33 and 34.
- the saw tooth wire 5 leaves the electrolyte bath during the conveying movement on a horizontal path and is in the conveying direction further cleaning device arranged behind the electrolyte bath 30 40 introduced.
- This further cleaning device 40 consists of 4 arranged one behind the other in the conveying direction Water baths in which the sawtooth wire is used to remove Electrolyte residues are rinsed, the contamination of the individual water baths decreases in the conveying direction, so that with the additional cleaning device 40 a particularly effective Cascade cleaning is effected.
- the sawtooth wire 5 After leaving the further cleaning device 40 the sawtooth wire 5 in the course of through the conveyor 60 caused conveyor movement in the preservation facility 50 where he preserved with an anti-rust agent becomes. Following this preservation device 50 passes the sawtooth wire the conveyor 60 and then wound on the take-up reel 70.
- the sawtooth wire 5 is inside the electrolyte bath 30 anodically to an externally controllable direct current source (not shown) coupled, the direct current strength in the electrolyte bath depending on the surface properties of the Sawtooth wire is controlled to ensure optimal treatment to ensure the sawtooth wire within the electrolyte bath.
