The use of accumulation  capstan  pay­ offs and take  ups is essential  where  a continuous (non-stop) process is required during spool change operation. The capstans  are  mounted ona horizontal axis in orderto minimize floor space or with vertical axis, in case of the  larger wire sizes, enabling  best capstan  accessibility for stringing up purpose. The accumulation capstans are typically used to pay-off and take up, on spools,  annealed  and  galvanized  low carbon wire, 
patented and phosphated or  galvanized  high  carbon  wire,  ACSR wire,  hard  drawn  and  bronze  coated high carbon wire (Bead wire), patented and   brass   coated high carbon wire (Steel Cord).
