Abstract
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.
