AI Technical Summary
Technical Problem
Existing technologies often result in knots and crushing during steel sheet winding, and these problems are difficult to effectively resolve when the steel sheet's properties change.
Method used
By using the apparent elastic modulus of the coil radial direction to calculate the tension mode, the internal stress state of the coil after winding is controlled to prevent knotting and crushing.
Benefits of technology
It effectively prevents knotting and crushing during the winding process under different steel plate properties, thereby improving the yield of finished products and intermediate materials.

Abstract
This invention relates to a method for determining a tension pattern and a method for winding a steel sheet. It provides a method that prevents at least one or both of knotting and crushing of a steel sheet wound into a coil shape, regardless of the properties of the steel sheet. The method determines the tension pattern applied to the steel sheet for winding it into a coil shape, characterized in that the tension pattern is calculated using the radial apparent modulus of elasticity of the coil.
