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.

In apparatus for the removal of moisture from air permeable material webs such as in the dyeing of dyed fabrics, finished facbrics and the like, comprising a rotating foraminous drum over which the web passes, a housing in which said drum is supported for rotation and fans, disposed in the end of the drum and supported to be adjustable longitudinally, to draw air through the periphery of the drum over a predetermined circumferential zone of the drum over which the web is running, the improvement comprising:
- a. the fans being a pair of fans disposed one in each end of the drum;
- b. a motor unit associated with each fan on which said fan is mounted;
- and
- c. actuation means for inserting said motor units and fans into the drum and withdrawing them therefrom to adjust the length of the zone over which the air is drawn through the web.
