Abstract
Abstract A seal for a clothes dryer includes a resin support strip, a fibrous wear strip secured to the resin strip, and a mounting to secure the resin strip in an annular orientation in the dryer so the wear strip engages a sealing edge in the dryer. The resin strip extends from the mounting across a space between the housing and the rotating drum of the dryer and overlies a portion of the wear strip in the region of the sealing edge to provide an air barrier between the housing and the rotating drum. The resin strip is also made for pressing the wear strip against the sealing edge with a predetermined force.
