▁Are as ▁of ▁thin ▁co pper ▁on ▁the ▁c ath ode ▁pl ates , ▁which ▁are ▁caused ▁by ▁short ▁circ uits , ▁are ▁difficult ▁to ▁separate ▁from ▁the ▁st ain less ▁steel ▁plate ▁due ▁to ▁their ▁lack ▁of ▁rig id ity . ▁Pl ates ▁bearing ▁such ▁areas ▁generally ▁had ▁to ▁be ▁rejected ▁from ▁the ▁stri pping ▁machine ▁and ▁stri pped ▁manually . ▁Similarly , ▁stick y ▁co pper ▁depos its ▁( gener ally ▁related ▁to ▁poor ▁surface ▁condition ▁on ▁the ▁c ath ode ▁plate , ▁such ▁as ▁cor rod ed ▁surfaces ▁or ▁impro per ▁mechanical ▁treatment ), ▁heavily ▁nod ulated ▁c ath ode ▁and ▁l amin ated ▁co pper ▁caused ▁problems ▁for ▁stri pping . ▁ ▁St ri pping ▁machine ▁development ▁foc uss ed ▁on ▁developing ▁a ▁device ▁that ▁could ▁be ▁seen ▁as ▁a ▁more ▁accommod ating ▁and ▁universal ▁stri pping ▁machine ▁that ▁could ▁handle ▁c ath ode ▁pl ates ▁with ▁problem ▁co pper ▁depos its ▁without ▁reject ing ▁them ▁or ▁slow ing ▁the ▁stri pping ▁rate . ▁ ▁The ▁result ▁of ▁this ▁work ▁was ▁a ▁new ▁robot ic ▁c ath ode ▁stri pping ▁machine . ▁It ▁incorpor ated ▁the ▁following ▁features : ▁ ▁a ▁stri pping ▁w edge ▁that ▁starts ▁removing ▁the ▁co pper ▁from ▁the ▁top ▁of ▁the ▁c ath ode ▁plate ▁and ▁moves ▁down ▁to ▁the ▁bottom ▁ ▁gu ides ▁to ▁support ▁the ▁co pper ▁during ▁the ▁down wards ▁motion ▁to ▁ensure ▁that ▁the ▁co pper ▁does ▁not ▁strip ▁prem ature ly ▁ ▁roll ers ▁designed ▁to ▁reduce ▁the ▁fr
