Abstract: A process and apparatus for drying textile stock and the like which assures even, thorough and quick drying of a batch of stock. The process embodies the steps of passing heated air under pressure through the stock along a multiplicity of paths so that the air will not channel itself, but passes through the stock substantially completely in contact with all of the wet fibers. A second feature of the process is the concept of pressing the stock while passing heated air through the same along a multiplicity of paths. The process is further characterized by engaging a column of the stock between two platens, both of which are perforated and one of which is movable and applying a head of heated air under pressure above the movable platen so that the pressure of the air causes the platen to act somewhat as a piston, the air also being forced through the holes in the movable platen to pass through the stock along a multiplicity of substantially discrete paths.
