Abstract

Apparatus for drying a traveling web which is permeable to air, has a rotating foraminous drum on which the web is wrapped and screw-type propellers mounted in each end of the drum, the diameters of the propellers closely approaching the inside diameters of the drum. Rotation of the propellers effects suction in the drum. Provision is made for heating air to be sucked through the web into the drum, and optionally for recirculating more or less of the air flowing from the ends of the drum back to the drum's periphery.
