摘要: A process for rolling and stretching of a sheet into a tape is provided. A sheet may be rolled into a rolled sheet in the nip between two rolls of the calender and the rolled sheet is stretched immediately thereafter into a tape on the surface of one of the two calender rolls. The speed of the rolled sheet on the surface of the calender roll may be higher than the speed of the calender roll. The position of the start of the neck-down of the rolled sheet and the rate of neck-down can be easily controlled by the proposed process.
