the drying chamber rotatable drums 14 and 15 have a porous surface permeable to air so that the drying air supplied by air supply 18 passes through the surface of drum 14 and to the interior 20 of drum 14 and on through the web to the exhaust hood 19 the web continues down around rotatable drum 15 as air continues to be supplied by drying chamber 18 and exhausted from the interior 21 of roll 15 and into the exhaust hood 19 at this point the web is dry enough that it can be contacted by air permeable or solid carrier rolls 16 which are located in a serpentine arrangement until the desired moisture of web 4 has been achieved the diameters and numbers of rotatable rolls 14 and 15 can be varied based on process requirements to achieve dryness that will permit a carrier roll to contact the web the illustrated embodiment employs through air drying tad to remove moisture from paper web 4 while it travels around the perimeter of rotatable drum 14 thus air supply 18 forces air in the direction of arrow a into the interior 20 of drum 14 on which fabric sheet 8 does not travel the air then travels from the interior 20 of drum 14 through the porous surface of drum 14 in the direction of arrow a toward exhaust hood 19 accordingly after the.
