Definitions
- the invention relates to a web guiding device with at least one guiding element, which is arranged after an application unit and serves as an air turn, for contactless web guiding in a machine used to manufacture and / or treat a material web, in particular paper or cardboard web. It also relates to a machine for producing and / or treating a material web, in particular
- Paper or cardboard web with at least one such web guiding device.
- a so-called airturn mostly has slot nozzles with a mutual slot nozzle spacing of about 20 to about 200 mm and a respective slot width that is greater than 1 mm. If rows of perforated nozzles are provided, the diameter of the perforated nozzle is generally greater than 2 mm.
- the web distance to the surface is usually greater than 5 mm, whereby it is usually in a range from 7 to 20 mm.
- the specific volume flow is usually in a range from 1000 to 30000 Nm 3 / h • m 2 .
- the invention has for its object to provide an improved web guiding device of the type mentioned, in which the aforementioned disadvantages are eliminated.
- a stable wrinkle-free and reliable, non-contact web guidance is to be achieved.
- the guide element has a guide surface which consists at least partially of air-permeable porous material which can be acted upon with compressed air in order to form an air cushion between the guide surface and the moving material web via the air flowing through this porous material.
- the high pressure loss on the porous material creates a very uniform air cushion, so that the material web is reliably guided at a relatively small distance from the surface. This results in a wrinkle-free run in particular.
- the relatively high internal pressure prevents any contact with the surface.
- the web guiding device can thus in particular comprise at least one guide element which is supplied with compressed air and has an open surface, but with a high pressure loss, through which air is pushed through from the inside. This creates a stable, even air cushion, both in terms of time and space, which guides the web without contact with the guide element.
- the guide element preferably comprises at least one pressure chamber, via which compressed air can be applied to the porous material.
- the porous material can be at least partially applied to a carrier containing the pressure chamber and provided with air passage openings.
- embodiments are also conceivable, for example, in which the porous material forms at least part of the pressure chamber wall.
- the pressure in the pressure chamber can in particular be greater than 0.5 bar, it preferably being greater than 1 bar.
- the specific volume flow in the porous material is expediently in a range from about 10 to about 5000 Nm 3 / h • m 2 .
- the hole or pore spacing or the distance between the outlet openings of the air-permeable porous material is preferably less than 1 mm.
- the porous material is especially designed in such a way that no individual jets are generated, but instead a very even air cushion, which ensures very good web guidance, which in any case remains contact-free, especially in the case of holes, tears or ribbons.
- the average size of the outlet openings, pores and / or holes of the porous material is less than 0.2 mm and preferably less than 0.1 mm.
- the porous material is preferably selected such that there is a high pressure loss from the inside to the surroundings, as a result of which a very uniform air cushion is generated.
- the Pressure loss in particular from the side facing away from the moving material web to the side of the porous material facing the material web, is greater than 0.2 bar and preferably greater than 0.8 bar.
- the thickness of the air cushion formed between the guide surface and the moving material web and thus the web distance to the surface is advantageously less than 5 mm and preferably less than 3 mm.
- the guide element can in particular be designed as a roller. This can be designed as a stationary or non-rotating roller or as a rotating, preferably driven roller.
- the air cushion is advantageously generated only on part of the circumference of the roller.
- the roller can have a diameter in a range from about 50 mm to about 1500 mm, for example.
- the guide element is only wrapped in the material web.
- the guide element is wrapped not only by the material web but also by at least one moving belt, in particular a wire belt.
- the moving belt in particular screen belt, can be guided between the guide element and the material web or on the side of the material web facing away from the guide element, ie it can lie on the outside.
- the material web or the moving belt can, for example, wrap around the guide element in accordance with a wrap angle whose range is from about 5 to about 260 °.
- the guide element is designed as an arc segment. It can have a constant radius of curvature in the machine direction or a radius of curvature that changes in the machine direction. In the latter case, the guide element can have a radius of curvature that changes continuously in the machine direction or a radius of curvature that changes in discrete steps in the machine direction.
- the guide element or its guide surface can in particular also have a course curved in the transverse direction.
- the radius of curvature of the guide element or the guide surface can change over the width extending in the transverse direction.
- the guide element is designed as an arc segment, it expediently has a segment height in a range from approximately 30 to approximately 500 mm.
- the radius of curvature of the guide surface is expediently in a range from approximately 5 to approximately 3000 mm.
- the guide element is composed of several individual segments in the transverse direction and / or in the machine direction.
- a common compressed air supply can be assigned to at least some of the segments.
- the segments can also be supplied at least partially via separate compressed air supplies.
- a zoned separation of compressed air is provided over individual separate segments and / or segment groups in the machine running direction and / or in the transverse direction.
- a special zone-wise pressure gradation can thus take place in the machine running direction or transverse direction.
- the guiding surface of the guiding element is formed by at least two layers each consisting at least partially of air-permeable porous material with preferably different properties.
- the pressure loss on the inner layer facing away from the material web can be smaller than on the outer layer.
- the porosity of the inner layer facing away from the material web can be higher or its hole spacing can be greater than in the outer layer.
- the hole diameter on the inner layer facing away from the material web can be larger than on the outer layer. It is also particularly advantageous if the layers consist at least partially of different material.
- Another preferred embodiment of the web guiding device according to the invention is characterized in that the material Inner layer facing away from the radial path consists only in a partial area of air-permeable porous material or is provided with air passage openings and is otherwise air-impermeable, so that an air cushion is generated only in a partial area of the guide element.
- the inner layer facing away from the material web can at least partially consist in particular of metal, GRP and / or CFRP.
- the inner layer facing away from the material web preferably provides the mechanical load-bearing capacity of the guide element or the guide surface.
- the outermost surface of the guide element facing the material web can in particular consist of fine-porous material. In particular, it can have a finer degree of porosity than the inner layer.
- this outermost surface of the guide element facing the material web can also consist of ceramic material, for example.
- the outermost surface of the guide element facing the material web is easy to clean, that is to say, for example, consists of an easy-to-clean material.
- the guide surface of the guide element is provided with air outlet openings which are preferably produced directly when the outermost surface is produced.
- the relevant air outlet openings therefore do not have to be introduced into the outermost surface by subsequent processing.
- the web guiding device according to the invention can be used in particular in a machine for producing and / or treating a material web, in particular paper or cardboard web.
- the surface treatment application unit is provided as a replacement for an air turn at least one corresponding web guiding device. Thanks to the small web distance and the even air cushion, wrinkle-free guidance is also ensured here. Further advantages result from the lower air volume and the smaller construction volume.
- the guide element can, for example, only be wrapped in the material web or, in addition to the material web, for example, can also be wrapped in at least one screen belt.
- At least one corresponding web guiding device is provided as a replacement for a respective spreader roller.
- the guide element in question is provided as a rotatably mounted roller, good emergency running properties also result, since even if the pressure supply fails, there can be no friction between the material web or a moving belt, for example a sieve belt and the rotating roller.
- the pressure loss of the layers can increase from the inside to the outside.
- the porosity can decrease from the inside out.
- the hole spacing can decrease from the inside to the outside.
- the hole diameter can also decrease from the inside to the outside.
- At least one web guiding device In order to be able to guide the material web safely and wrinkle-free, it is advantageous to arrange at least one web guiding device immediately before, preferably also immediately after a contactless drying section.
- the contactless drying sections are generally designed as infrared and / or convection dryers. Contactless drying is particularly necessary for coated or very moist material webs.
- the guide elements of the web guide cleaning form only a relatively thin air cushion with the material web, which minimizes the risk of wrinkles. In addition, the guide elements require relatively little compressed air.
- Contactless drying devices can also be assigned to the guide elements of the web guiding device in order to intensify the drying of the material web. These drying devices are located opposite the guide elements.
