Research on Influencing Factors and Solutions for Cord Thickness Uniformity
The factors affecting the thickness uniformity of cord fabric and their solutions were studied.The results showed that the uniformity of cord fabric thickness could not be effectively improved by optimizing conventional process parameters(e.g.,adjusting the axial crossing value and pre-bending stress).The fundamental reason for the saddle shaped distribution of uniformity of cord fabric thickness was the damage and deformation of the roller in the overlapping area of the bubble knife stroke,and replacing the roller was the fundamental method to solve the problem.After replacing the roller,the range uniformity of cord fabric thickness decreased from 0.20 mm to below 0.05 mm,which could meet production requirements.
