- a discharge manifold 36 is mounted between the spaced adjacent lower edges of the anodes 23 and 24, where it extends parallel to the surface of the cathode drum adjacent the line of deepest immersion thereof.
- the discharge manifold is supported in place by means of a pair of end brackets 37 (only one of which is shown in Fig. 1) and one or more center brackets 38.
- a solution distribution compartment 42 is 1 defined between the lower member.39 and the partition 41, and a solution discharge compartment 43 is defined between the upper member 40 and the partition 41.
- the discharge compartment is preferably divided into a plurality of sub-compartments 44 by a series of spaced transverse partitions 45.
- a solution inlet conduit 46 is provided for admitting electrolyte to the distribution comfrom the inlet conduit, thereby to insure substantially uniform distribution of solution to each of the discharge subcompartments 44.
- At least one and preferably two rows of closely spaced solution outlet openings 48 are formed j in the upper member 40 defining the solution discharge compartment.
- the discharge manifold is mounted so that the streams of solution projected from the discharge openings 48 are delivered into the narrow electrolyte spaces 25 and 26 between the anodes and the cathode face of drum 16.
- the solution inlet conduit 46 is connected to a valved supply pipe 49 through which electrolyte solution under pressure is delivered to the apparatus.
- the tank 10 is filled with a suitable electrolyte, c. g. an acidic aqueous solution of copper sulfate.
- a source of direct current is connected to the cathode drum 16 and to the anodes 23 and 24.
- the drive shaft 22 is set in operation, whereby the durm 16 is slowly rotated (in a counterclockwise direction as viewed in Fig. l).
- the voltage between anodes and cathode is high enough so that copper is electrodeposited from the electrolyte in the spaces 25 and 26 between anodes and cathode on to the surface of the cathode drum.
- this electrodeposit is carried to above the surface of the electrolyte in the tank. conventionally, the deposit on the drum is carefully washed to remove residual electrolyte (by washing means not shown in the drawings). The electrodeposit then is stripped from the face of the drum in the form of the thin sheet 30 and is wound into the coil 32.
- the face of the drum from which the copper sheet 30 has been stripped passes under a polishing roll 50 which is continuously rotated at relatively high peripheral speed by a drive chain 51 which connects it to a continuously driven high speed polisher drive shaft 52.
- the polishing roll 50 maintains a fine smooth surface on the cathode drum to insure the formation of a cathode deposit of good quality and to insure ease of stripping of the deposit from the cathode.
- electrolyte solution is introduced continuously and under pressure from the supply pipe 49 through the inlet conduit 46 to the discharge manifold 36.
- This electrolyte which enters the distribution compartment 42 and is distributed thereby to the several discharge sub-compartments 44, is forcibly projected as a series of high velocity streams through the discharge outlets 48 into the electrolyte spaces 25 and 26.
- the electrolyte of thesestreams together with electrolyte present in the tank and which is set into circulation by the force of the streams, flows upwardly through the electrolyte spaces toward the surface of the electrolyte'at each side of the drum.
- the electrodeposited film of copper formed on the cathode drum surface while carrying out the method of this invention is of exceptional uniformity. Its gage thickness across the entire width of the drum issubject to but slight variation, and it is remarkably free of pinholes and other porosity even when stripped from the drum in sheets of extreme thinness (e. g. one ounce in weight per square foot of surface area, which in the case of copper corresponds to an average gage thickness of only a little over 0.001 inch).
- the amount of acid electrolyte mist carried into the at mosphere is very greatly reduced, with the result that working conditions in the vicinity of the apparatus are greatly improved, the discoloring effect of such mist on the stripped electrodeposited sheet is eliminated, and the corrosive effect of the atmosphere on machine parts is greatly reduced.
- the splashing and sloshing of electrolyte at its surface level in the tank is eliminated with a number of consequent advantages. Notable among these is the substantial elimination of splashing of the electrolyte on to the surface of the cathode, in the vicinity of the polishing roll 50, which invariably results in occasionally entrapping specks of lead dust generated by the polishing roll 50 and causes them to adhere to the surface of the cathode drum.
