Description

First advances to increase package size in steel tire cord manufacturing came from reducing labor by reducing the number of times payoff and take-up carriers require changing. However, there are more profound effects when very large carriers contain no welds. Reduction of waste, increased equipment utilization, decreased breakage at wet drawing and twisting, improved drawing performance, reduction or elimination of partial fine drawing payoff spools, and more consistent product quality are all benefits. This paper suggests that, rather than determining the amount of material on a carrier based on length, a preferred method applies material on a take-up capable of carrying the weight of an entire coil through the entire manufacturing process regardless of continuous length.
