    Web-drying apparatus having a plane of lower blow boxes underlying the path of travel of the web to blow dry air against the undersurface of the web to support the same in closely-spaced relation to the blow box. Upper blow boxes are disposed on the upper side of the web closely adjacent the plane of travel of the web. The upper blow boxes are disposed in pairs extending diagonally across the full width of the web and terminating at opposite ends in fan chambers which are located in spaced locations along the sides of the path of travel of the web. The blow boxes in each pair diverge from the fan chamber, one extending forwardly and one extending rearwardly in the direction of the web travel to provide an angular space therebetween which provides free access to the web path and also to enable exhaust spent drying medium therethrough. The opposite ends of the blow boxes are closed in alternation.

    2. The device according to claim 1, about t and and - h. This is due to the fact that in each pair a mountaineer of one of the groups is provided with1080759
    a lid placed in the ion chamber in the corresponding Hungarian center.
    The invention relates to the cyw technique of roll materials and can be used in the textile, paper and other industries. A multi-light device for drying roll materials is known that contains gas-gas targets placed under the material and gas distribution ducts installed above the material in the transverse direction -0. However, with a small gap between the boxes and the gas distributors for cleaning the device from possible ruptures of the material roll . The aim of the invention is to improve the operating conditions of the device. The goal is achieved by assembling the boxes in groups arranged in pairs at acute angles to each other, let us take adjacent lars connected to venhil chambers located on opposite sides of the material being dried. In this case, in each pair, the end of one of the groups can be equipped with a lid located in the co-lung ventilation chamber. FIG. 1 shows a section of a device for drying roll materials, a general view; in fig. , 2 - the same, top view; in fig. 3 - the same cross section. The device contains an assembly 1, along which the rolled material 2 is transported. On two sides in the transverse direction of movement of the material 2 are placed the skin 3, in which the ventilation chambers 4 are installed with fans 5. Each chamber is provided with an air inlet 6, a source 7 of and a pipe 8 for supplying heated air to the gas distribution ducts 9, which are grouped and installed in pairs at an angle to one another. The lower part of each group of ducts 9 is provided with perforations 10. The end of one of the groups of ducts 9 in each pair has a lid 11. The material is pulled through unit 1 in a floating state created by jets of air coming from drying boxes 12 installed under the material 2 in the transverse direction of its movement (along arrow A). A lot of brown-haired device works as follows. The rolled material 2 enters unit 1 along arrow A in the form of a tape and passes between the gas distributors located under and above the belt, which are made in the form of groups of ducts 9 and transverse drying ducts 12. Air heated in the ventilation chambers 4 from the source 7 vapor with the help of fans 5 through pipes 8 into one of the groups of each pair of ducts 9, from where through the holes of the perfrar. 10 postuttaet to the surface of the material. From the bottom of material 2, it is maintained in a floating state by jets of air coming from drying boxes 12. By distributing two groups of each pair of ducts 9 to the acute angle between them, a gas outlet is formed. Such a constructive use of the exhaust cavities allows for quick cleaning of the device in case of a roll break.
