Title: Wire patenting using lead bath - uses wire fed from bath through gravel bed with constantly changing path ensuring wire passes through non-contaminated gravel
Inventor: EWERT WOLFRAM
IPC: C21D9/64
Filed: 1990-11-22
Abstract: Wire patenting uses a Pb bath and an inclined bed of coke gravel and has three guide means for directing the wire out of the bath and through the bed. The outer two means are rollers and the central means is a guide plate which slowly moves up and then down in a vertical plane as the guide arm moves up through the gravel bed and then back down. Pref. movement path of the guide plate is 20 deg. max. above the straight line joining the two outer rolls. During its movement cycle the guide plate only touches the wire for a short period.  The guide arm acts as a pusher unit to move contaminated gravel downwards and into the bath as a moveable funnel feeds clean gravel over the bed. USE/ADVANTAGE - Removes excess Pb from the patented wire. By constantly changing the path of the wire through the bed, clean, Pb-free gravel is employed.
