A guard at the inlet side of the nip of two rolls in a calender has a hollow support for two blocking devices with movable sections extending close to the peripheral surfaces of the rolls to prevent injury to the fingers of an operator. The support defines one or more channels for steam or for another fluid medium which is discharged through one or more rows of ports to moisturize a running web of paper, foil or textile material or to dry, heat or cool the web and/or the rolls.

Guard for the nips of rolls in calenders and like machines

A calender wherein the intermediate rolls of a stack of rolls are mounted on pairs of levers pivotable on carriages which are movable up and down in vertical ways provided therefor in the frame. This renders it possible to change the levels of the intermediate rolls without any or without appreciable shifting of the centers of nips of neighboring rolls from a common vertical plane. The carriages are suspended on composite feed screws which can be rotated to move neighboring carriages nearer to or further away from each other.
