    摘要: A biaxially oriented polyester film which is well balanced between sliding properties and transparency and having an enhanced uniformity in thickness is prepared by a process wherein a polyester, predominantly comprised of polyethylene terephthalate, is extruded into a sheet form extrudate; the extrudate is quenched to a temperature of below Tg to obtain a solidified, substantially amorphous film; the film is drawn in the longitudinal direction at a drawing ratio of larger than 2.4 but smaller than 6.5; the film is quenched; and then, the film is drawn in the transverse direction at a drawing ratio of at least 2.5. The drawing in the longitudinal direction is carried out in two steps wherein:(i) in the first drawing step, the substantially amorphous film is drawn in one or more stages at a total drawing zone length (l.sub.1) of at least 50 mm so that the resulting polyester film possesses a birefringence of 1.times.10.sup.-3 to 12.times.10.sup.-3 ;(ii) the drawn film is kept, without being quenched to a temperature of not higher than the Tg, in contact with a roll maintained at 100.degree. to 130.degree. C.; and then,(iii) in the second drawing step, the film is drawn at a drawing ratio of larger than 1.6 but smaller than 2.7 in one stage at a drawing zone length of shorter than l.sub.1 /2.

The large-diameter ram 13 is inserted in the large-diameter cylinder 11, and the small-diameter ram 25 is inserted in the small-diameter cylinder 31. The proximal end portion of the tie bar 15 is connected directly to the small-diameter ram 25. Large oil chambers 11c and 11d are provided on both sides of the large-diameter ram 13, and a small oil chamber 11e is provided on the tie bar connection side of the small-diameter ram 25. An oil pressure is supplied appropriately to each of the large oil chambers and the small oil chamber in the die clamping cylinder to appropriately move the tie bar 15. The apparatus constructed as described above can be manufactured at a low cost, and useless time for eliminating a gap between a ring grooves in the tie bar and an engagement teeth of half nuts caused by the adjustment to die thickness can be reduced.
