Abstract

PURPOSE: To avoid thickness fluctuation of thermoplastic drawn film by effecting an easy and costless control through controlling the widthwise tempereture distribution in the preheating region or the widthwise hot air distribution.
CONSTITUTION: When a thermoplastic resin film is drawn by means of Tentar method one shaft to longitudinal direction and two shafts to both longitudinal and lateral direction, thickness distribution of width direction of film after the completion of drawing is measured. After that, according to the thickness distribution measured, temperature distribution to the width direction or heat wind quantity distribution to the width rirection just before the drawing is adequately changed. By doing so, the thickness to the direction of the width of the drawing film can be uniform. As a thermoplastic resin to be applied, nylon 6, nylon 66, polyethylene terephtalate, polypropylene, polyethylene and so on are applied.
