Steel Cord Manufacturing
Special considerations applicable to a narrow scope of industries
(Ex: the reversal of the wire wound on the spools at each bunching operation)
Cable manufacturing (electric/energy/fiber-optic)
Nylon cord manufacturing
Copper rod manufacturing
The Manufacturing Process
Steel rod wire”, is thinned into “filament”s which are used in successive bunching operations to construct the “steel cord” final products.
Intermediate wire products are wound onto spools of varying capacities.
The Manufacturing Process
Payoff: filament coming out of wet drawing
Core: bunched wires entering next bunching operation
Take-up: output of each bunching operation
Construction: the final steel cord product
The “take-up” becomes the “core” for the following bunching operation.
Research Motivation
“Optimal” spool lengths for each bunching operation
Minimize rejected spools
Such that spool lengths are within a certain percentage of the current spool lengths
