Abstract
A sheet transfer apparatus is disclosed for transferring a web from a drying section to a calender. The apparatus includes a looped felt for supporting the web thereon from the drying section. A lead-out roll is disposed upstream relative to the calender for guiding the felt such that the felt is disposed between the lead-out roll and the web. A full width web blowing device connected to a source of pressurized air is disposed adjacent to the lead-out roll for selectively blowing the web off of the felt. A movable sheet transfer roll is disposed in the vicinity of the lead-out roll, the transfer roll being movable from a first position to a second position adjacent to the lead-out roll. The arrangement is such that when the transfer roll is disposed in the second position thereof, the blowing device blows the full width web off of the felt and onto the transfer roll for subsequent guidance thereof to the calender.
