专利摘要:
Web material is carried on air to advance the material in a fixed stable floating position through one or more decks of a treating plant, preferably a drier. The air is supplied through pairs of apertures arranged in the upper surface of blow-boxes distributed in the conveying path of the material which apertures eject the air in pairs of streams facing away from each other. To reduce deflection of the material between said pair of apertures the space between said apertures is supplied separately with a great volume of secondary air of the same static pressure as that prevailing on the upper surface of the material, which secondary air is taken along by ejector effect by the primary air streams ejected from the apertures of the blow-boxes.

S54) DEVICE FOR MAINTAINING MOVING
权利要求:
Claims (3)
[1]
The invention relates to devices for maintaining a moving strip material on an air nor: a choke that is used simultaneously with the processing of a strip material, for example, drying, heating, moistening, etc. A device for supporting a moving strip material on an air cushion is known, which contains pressure chambers connected to a source of compressed air, each having multidirectional openings in the upper wall and vertical holes arranged between these openings. material. This oscillation or beating of the material is caused by feeding perpendicular to the plane of the air material at a high flow rate. The purpose of the invention is to increase the reliability of the device for maintaining a moving strip material on an air cushion. This goal is achieved by the fact that in a device for supporting a moving strip material on an air cushion containing pressure chambers connected to a source of compressed air, each with multidirectional holes in the upper wall and vertical holes between these holes, each chamber has vertical partitions separating it into three cavities, two of which are located under multidirectional apertures and communicate with the source of the hedgehog, the air, and a third between the first two Calne openings and bottom is communicated with the atmosphere with in vertical partitions has holes, and the device has a fence plate raspolo- conjugated under pressure chambers. FIG. Figure 1 shows a device for supporting a moving strip material in an air cushion incision; in fig. 2 is a view A of FIG. one; in fig. 3 shows an embodiment of a device with openings in vertical partitions; Figs 4, 5 and 6 show embodiments of the intake plates. A device for supporting a moving strip material on an air cushion contains pressure chambers 1-3 connected to a source of compressed air (not: shown), each with 4 differently directed openings 5 and 6 in the top wall (in the drawings, openings are in the form of slits and The vertical openings 7 arranged between these openings 7. Each pressure chamber 1-3 has vertical partitions 8 and 9 dividing it into three cavities 10-12. The cavities 10 and 12 are located under openings 5 and 6 and communicate with a source i of compressed air and the cavity 11 is located between the cavities 10 and 12, communicates with the atmosphere under the opening 7 and below.In one embodiment, the devices in partitions 8 and 9 are from, and 13 and 14. In addition, the device may have intake plates 15 Located below chambers 1–3, as shown in Figures 4–6, the upper wall 4 of each pressure chamber 1–3 has a flat or slightly convex surface.The pressure chambers are installed, the shower is perpendicular to the transport path of the moving strip material 16, however they can be oriented and longitudinal One after another, the air is supplied to each pressure chamber 1-3 with an excess pressure (indicated by a (+) sign) and passing at high speed through the holes 5, 6, 13 and 14. In the space between the wall surfaces 4 of the chambers 1- 3 and the surface of the material 16, the air jets move parallel to these surfaces, as a result of which scaling occurs, which tightens these surfaces until the distance between them becomes so small that the static pressure drop in the flow is not balanced with this force. It has been found that in the space between the holes 5 and in the absence of the holes 7 there is a discharge, due to which the weight of the material 16 appears undesired deflection of the material in this zone. But since each chamber 1-3 has openings 7, located between the oppositely directed openings 5 and 6, which are connected with the atmosphere, there is no undesirable deflection of material 16 in the zone between openings 5 and 6. Plates. 15 are intended to collect a portion of the exhaust air and re-direct it to the material 16. FIG. 4, the upper wall 4 of each pressure chamber 1-3 is elongated due to the downwardly curved section 17, which is preferably positioned at an angle of 15-45 depending on the ejection rate. Between the intake plates 1 6 and the portions 17 of the walls 4 there are openings for suction of exhaust air, which is then supplied to the openings 7. The intake plates 15 (Fig. 57 are located only on one side of the pressure chambers 1-3. The proposed device improves its reliability operation by reducing the likelihood of the beating of the material being transported. Claim 1. Device for supporting a moving strip material on an air cushion, containing pressure chambers connected to a source of compressed air, and There are multidirectional openings in the upper wall and vertical openings between these openings, differently in that, in order to increase the reliability of its operation, each chamber has vertical partitions dividing it into three cavities, two of which are located under opposite openings They communicate with the compressed air source, and a third between the first two under the vertical openings and below communicate with the atmosphere. 2. A device according to claim 1, which is tl in the case that there are holes in the vertical partitions.
