Abstract

The process of continuous elongation of tubular films after exiting the extruder is considered in this paper, with special attention to applications relating to electronic wire and cable manufacturing. The polymer sheath, after exiting the extruder, is considered as an axi-symmetric isothermal tube with inertia and Newtonian viscosity. The non-linear equations of motion evaluated for the stretching tube are solved numerically using a Newton-Raphson method, evaluating the profile of the elongated geometry. The sensitivity of the resulting profile to processing variables is examined.
