Theories about the behavior of film deformation from the exit of a flat sheeting die to a take-up roll, had been made public little if anything. Kanai published a theory [17] that can simulate temperature, velocity, thickness, strain rate, stress etc. during the film running downward. Similarity between this theory and the theory of melt spinning is high, so the present writer developed Kanai's equations to the level of adopting the same procedure for solving the melt spinning equations. This chapter presents Kanai's theory and equations together with the developed ones, and a calculation example using these equations. [17] T. Kanai, Sen-i Gakkaishi, 41 (10) T-409 ('85) |
