Abstract

1525789 Forming films R I BATYREV S I GDALIN A S ZORIN V N KONSTANTINOV V I KLOCHKOV V V MALININ I I RUMYANTSEV V G SEMENOV I I SPORYKHIN V A YAKOVLEV and A I NEKRASHEVICH 6 Dec 1976 50681/76 Heading B5B An extruded web is passed through an electrostatic field 4 then round an intermediate roller 3, is stretched then passed round a cooling roller 2, further stretching taking place between the intermediate and cooling roller. The web is cooled and oriented. An electrostatic field 5, may also be applied to the film between the intermediate and the cooling roller. An apparatus consists of an extruder 19 with die 1 under which is disposed vertically intermediate roll 3, cooling roll 2, slow rotating cooling rolls 6, 7; orienting rolls 8, 9, fast rotating cooling rolls 10-14; the rolls arranged in two groups and mounted on cross-pieces 16 and 17. Cross piece 17 also carries ionizers 4 and 5, and heater 15. The cross-pieces are mounted on horizontal guideways 18 and are capable of lateral movement. Roll 3 is driven separately from the other rollers and rollers 6, 7 and 8 are provided with cooling systems and also a thermostatic system.
