[Class 34 (i).] Paper, cloth or yarn is formed into loops supported by poles and carrying rollers pressing down the material between the poles in a drying chamber 1, the poles and rods moving in separate cycles. The material x fed at 7 into the chamber is supported in loops by poles 5 on a conveyer 4. Rollers 10 are fed at intervals from an inclined rack 12 by star wheels 15 on to the material between the poles 5. Trunnions of the rollers 10 engage against ribs 18 between the flanges 17 on the wheels 15. Each flange 17 is concave at 19 for engagement against a circular element 20 with a flange 21 with a pin 22 engaging in radial slots 23 between the flanges 17. A flat face 24 on the element 20 allows the concave part 19 of the flange to pass when the pin 21 engages a slot. The rollers are guided at the bottom of the loops between plates 91 on a synchronized conveyer 90. Each pole 5 carries a pinion 70 to engage a rigid rack 71 so that the pole is rotated and the material moves over it and is dried equally. The material is withdrawn at 8 between rollers 9, 9a driven from a separate shaft 62. An elevator wheel 25 is mounted on each side of the conveyer and has teeth 26 entering between the poles and engaging the rollers 10 to lift them on to a conveyer 28 returning them to the star wheel 15 for reuse. An escapement 30 prevents the rollers running down the conveyer 28. A switch 75 on a lever 78 is operated by a rising roller 10 in the last loop to stop the withdrawing rollers 9, 9a while the roller 10 moves along the lever 78 into a hook 27 on the wheel 25. The lever then operates the switch again, and the rollers 9, 9a rotate.
