Abstract
Used hot air exhausted from perforated mangle drums 12-14 and/or steam condensate from curved guide troughs 15-17 cooperating with the drums is passed through the interior of a hollow, unperforated predryer cylinder 18. A pair of curved transport belts 40, 41 surround the bottom half of the cylinder and are driven at the same peripheral speed thereof to press laundry articles against the heated cylinder and to reverse their direction. Heating manifolds 46, 47 are mounted inside the transport belt runs.
Claims13
A mangle for pressing and drying damp laundry articles including a plurality of rotatably mounted, padded, perforated hollow drums attached to a vacuum device, and an equal plurality of cooperable, perforated, curved hollow troughs which define transport paths with the drums and which are heated by high pressure steam, characterized by:
- a rotatably mounted hollow imperforate pre-dryer cylinder (18) disposed in front of the drums (12-14) in the operating direction, means for heating the cylinder with used steam condensate withdrawn from the troughs, and means for conveying the laundry articles around and in frictionless contact with the outer wall of the cylinder.
