The present paper describes part of experimental investigation on especially laboratory computerized device which was built up with main purpose to perform sheet stripe tensile test over drawbead in conditions of variable contact pressure and variable drawbead height during the sliding and forming process. Test plan was provided use of 10 linear and nonlinear functions of contact pressure as well as 10 functions of drawbead height. In this paper , the procedures of determination parabolic and linear function of pressure and drawbead height are given. Examples of usage this functions in concrete experiment and obtained results also are given. Test results indicate that variable pressure and drawbead height can significantly influence the course of the sliding and forming process.
