Board machines are largely designed as for paper, except that the wire section consists of several formers to produce the ply, both longitudinal and round, the dryer section often incorporates a calender and the board sheet may not be reeled up, but fed directly to a sheeter. In Figure 1, an example for paper and board making machines is shown schematically.

Synthetic wires (woven plastic) are commonly used. Water is also removed by the use of hydrofoils, suction units and a couch or wire suction roll. Equipment, such as guides and tension rollers and spraying pipes are also included in this section. A Dandy roll, which is a hollow roll with a variety of coverings, may be used to compact the fibres and apply a watermark or wove. Round wires may also be used, to form a web.

Figure 4 — Example for a drying section (safety devices are not shown) 3.6 size press purpose of the size press is to add a solution of water and starch or other application media like pigment coating. This improves the surface of the paper for printing purposes; the size press can be a simple pond or bath arrangement with two rollers, but more commonly consists of a series of rollers and resembles coating heads in design, delivering a pre-metered film of starch on either side of a web 3.7 coating unit units applying pigments, inks or fillers Note 1 to entry: Included are applicator rolls, jet applicators, spray nozzles and metering devices, such as blades or rods. There are a variety of methods, such as roll coating, blade coating, air-knife coating or cast coating. 3.8 flotation dryer convection dryers where a system of jets is used to create a stream of hot air on both sides along the paper web; the air stream keeps the web in suspension and carries it through the dryer; flotation dryers are commonly used in combination with coating units for drying the coating applied 3.9 infrared dryer equipment for drying the web by heating with infrared radiation. Infrared radiators are gas-heated or electrically heated Note 1 to entry: They are commonly used in combination with coating units for drying the coat applied. 3.10 calender/smoothing unit paper is smoothed using an ironing method, which consists of a stack of hot rollers mounted in pairs; this action consolidates, polishes and glazes the surface of the paper; the rollers may be steel, rubber or fibre packed or a combination of these 3.11 measuring unit measuring devices consisting of an ionising and/or non-ionising radiation source to gauge weight, moisture content and other characteristics SIST EN 1034-16:2012
