A threading belt (A) extends around a plurality of pulleys and guide rollers (B). A loading station (C) is disposed along a linear run of the threading belt for inserting a web between hingedly connected gripping portions (16, 18) of the threading belt. The loading station includes a wedge-shaped belt spreading member (52) for urging the gripping portions of the belt apart and providing a groove (60) through which the web is fed between the gripping portions. The threading belt conveys the web through a floating dryer (D) to an unloading station (E). The unloading station includes an ejector member (90) which spreads the belt and a nozzle (96) for directing a jet of air between the belt gripping portions to eject the web therefrom. The belt includes a main woven fabric strength member (24) extending along the hinged connection of the gripping portions. A fabric cover (20) surrounds the gripping and hinge portions and is impregnated with a silicon rubber (22). The silicon rubber defines inwardly facing, corrugated gripping surfaces (30, 32) of the gripping portion and hermetically seals the main strength member. Lip portions (12, 14) which include tensile strengthening members (26, 28) running longitudinally therein are connected with the free ends of the gripping portions.
