Abstract
163,668. Sch³rmann, C. May 20, 1920, [Convention date]. Calendering.-In multiroll paper calenders, having 8 to 14 rolls, either or both the usual top and bottom hard cast-metal rolls are replaced by resilient or elastic (paper or cotton) rolls a, a<1> having steel shafts, and the drive is effected from the second or fourth roll b or b<1>. The total number of hard rolls is reduced by 1 and the number, of elastic increased by 1. Where the drive is from the fourth roll, it is desirable to drive the second roll therefrom with a slight lead, in order to maintain the tensile stress in the paper and prevent tearing at the driving-roll. The rolls may be slightly staggered as shown. Specification 7992/11 is referred to.
