Conclusions
Mathematical expressions have been obtained for calculating stretching forces for various schemes of stretching stations in apparatus for plasticized stretching.
A qualitative comparative evaluation has been given for schemes of stretching stations in apparatus for plasticized stretching; it has shown a preference for a scheme with self-tightening rolls.
Unreliability of the operation of stretching stations at low values of the coefficient of friction (0.01–0.05) has been demonstrated; this causes a need to search for ways to increase the coefficient of friction.
