Background
In the aspect of tire manufacturing, with the increasing requirements of people on the safety performance and the comfort performance of tires, the uniformity of the thickness of a cord fabric, the flatness of the surface of the cord fabric and other internal qualities of the tires are also increasingly concerned. Wherein, the flatness of the surface of the curtain cloth is related to whether the tightness degree of the steel wires in the curtain cloth is consistent. When the curtain cloth is subjected to external force, the steel wires in the curtain cloth are in a tensioning state. When the instant impact force of the tire subjected to road surface obstacle exceeds the maximum bearing strength of a certain steel wire, the steel wire can be broken, other steel wires are broken immediately, and a series of interlocking reactions are caused: the carcass cord fabric causes the zipper to burst; the belt ply cord fabric causes crown explosion. Therefore, the control of the paying-off tension of the steel wire is particularly important.
Wirecord fabric is the primary stress component in a tire as the carcass material for forming the carcass and belt. For the belt layer, the rigidity thereof largely affects the strength of the tire and the service performance such as the profile of the tire after inflation. The stress is borne by each steel wire which forms the curtain cloth, and the stress of each steel wire is required to be consistent. Therefore, the more uniform and better the tensioning degree of the steel wires in the curtain cloth, namely, the smaller and better the fluctuation of the paying-off tension of the single steel wires and the paying-off tension difference value between every two steel wires are controlled during rolling, and the smoother and better the steel wires are represented on the surface of the rolled curtain cloth.
An important process in the tire forming process is to sequentially attach multiple layers of materials (pre-composite layers, plies, belts and tread layers) to a metal forming drum, so that in the attaching process, how to adjust the tension of the tire steel wire paying-off by controlling the rotating speed of the metal forming drum is a technical problem which needs to be solved by those skilled in the art.
