Abstract

1424499 Calendering HERMANN BERSTORFF MASCHINENBAU GmbH 13 Aug 1974 [23 Aug 1973] 35606/74 Heading B5A Powdered material, e.g. P.V.C. is electrostatically charged as it is dispensed into the first roller gap 8 of a calender or rolling mill to improve the draw-in of the material. The resulting film may have electrostatic charge removed by a discharger 9 associated with a roller 2 of the gap 8.
