Background

The steel cord fabric is a framework material of the tire, the quality of the steel cord fabric directly influences the quality of the tire, and due to the characteristic that the steel cord fabric cannot be recycled, the steel cord fabric needs to be discarded when the steel cord fabric is abnormal, so that the production cost is increased, and when the steel cord fabric is closed, the larger discarded amount of the steel wire tailings is also one of main reasons for increasing the production cost.

When the rolled steel cord is close to the tail part of about 100m, the steel cord can be subjected to ending operation by adopting a steel cord ending device, at present, in the production process of a rolling procedure, the steel cord is firstly pulled from an ingot wheel, and is pulled towards a rolling machine after passing through a branch threading plate and a main threading plate above an oscillating arm of the ingot wheel. When the steel cord fabric is in ending operation, the steel cord which firstly drops from the spindle wheel is lack of the restraint of the spindle wheel, so that the steel cord which drops from the spindle wheel is lack of tension and is randomly drawn forwards, the steel cord which is lack of the tension restraint can be crossed when being drawn, so that the steel cord is scattered at the distribution threading plate and the total threading plate, the steel cord with smaller single-wire tension is firstly disordered from the warping roller, so that the steel wire tailings are discarded, after the steel cord drops, the tension of the single-wire which drops from the spindle is inconsistent with that of the single-wire which does not drop from the spindle, and the wire jumping of the steel cord fabric after being rolled is poor, so that the discarded amount of the steel wire tailings is increased, and the quality of the steel cord fabric is reduced.

In conclusion, the problem of poor EPI (number per inch) of the steel cord caused by disorder of steel wires when the rolled steel cord is close to the tail part of about 100m is solved, so that the EPI (number per inch) qualification of the steel cord at the ending is ensured, the quality of the steel cord is improved, the waste amount of steel wire tailings is reduced, the production cost is reduced, and the method has important significance.
