Abstract: A multiple-roll calender for producing thermoplastics films, in which, viewed in the direction of working, a penultimate roll is spaced from the roll which immediately precedes it so that for a period as it travels from said preceding roll to the penultimate roll the material being calendered is not in contact with any of the rolls, and said penultimate roll and a final roll which together define a final working gap, are provided with drive means whereby they can be driven at varying speeds independently of the other rolls.A guide roller may be provided to guide the material centrally into the final working gap or a pull-off roller or pair of pull-off rollers and a constant pressure roller may be provided to guide the material to the final working gap. Alternatively a pull-off roller and a scraper device, defining with the penultimate roll a gap which narrows in a downstream direction may be provided.
