(Safety devices are not shown) 3.3 former section (wire section) device for forming a continuous web from fibre diluted in water (stock) using wire formers for forming the sheets and including head box, wires, rollers, roller stretching equipment, lifting devices and spraying pipes
Note 1 to entry: An example of the former and press section is shown in Figure 3. For sheet forming, the stock is supplied onto a large-diameter roll (forming roll) designed to preserve and enhance the paper properties created in the head box. The head box delivers the stock by means of spray jets with uniform velocity over the entire machine width. Growing demands for softness and more efficient fibre use have led to increased application of head boxes suitable for multiple-ply products. There are two types of former sections, one equipped with a pick-up system and one where the sheet is carried directly to the pressure rolls and the Yankee dryer so that a pick-up system is not required. 3.4 press section part of the wet end of a tissue making machine which carries out one or several press functions extending from the sheet pick-up to the first dryer section and including all pressure and lead rolls, spraying pipes, suction boxes and wire tension devices, being nowadays generally designed as cantilever for easier changing of felts and wires
Note 1 to entry: An example of a press section is illustrated in Figure 3. Felt conditioning is normally located between the last pressure roll and the first paper side felt roll in the return run. Tissue machines can be equipped with one or two pressure rolls. The first roll is normally a suction pressure roll and the optional second roll is a blind drilled roll. Press roll configuration influences the sheet properties and sheet dryness. Paper with higher bulk and softness can be produced on single-roll machines. SIST EN 1034-17:2012

Note 1 to entry: Some terms special for the drying section are defined below.  Yankee cylinder (creping cylinder): steam-heated drying cylinder with a very large diameter and a polished surface, completely or largely responsible for drying the paper web. It works in conjunction with the press roll to dry the paper in combination with the drying hood and finally provides the surface of the creping process;  Yankee dryer: assembly within a Yankee cylinder, press roll and drying hood;  drying hood: equipment that functions to improve the drying process and the tissue quality by optimising the air temperature, velocity and distance to the tissue web Air circulation and heat recovery systems may also be included in this machinery;  creping: the creping process is affected by both the blade geometry and the surface conditions of the Yankee dryer. The creping process can be optimised by using adjustable creping doctors. Tissue making machines are normally equipped with spray systems for coating the Yankee surface with chemical substances;  through-air drying (TAD): method for increasing bulk and softness. Conventional tissue making machines press the sheet onto a Yankee cylinder. TAD removes water by a process to dry a sheet by passing high temperature air through the sheet that has not been pressed;  tail threading device: device for threading the paper web through the machine, for example following the creeping doctor;  equipment for web support: equipment to prevent the web from fluttering or creating waves;  equipment for dust removal: system for removal of dusts. 3.6 calender assembly where the shape and surface of the paper tissue is changed by a combination of heat and/or mechanical treatment in a roll nip. 3.7 measuring device, scanner measuring device consisting of a traversing measuring sensor used to determine the basis weight and moisture content and which is generally located between creping unit and the reel section SIST EN 1034-17:2012

Note 1 to entry: The reel stand and the shaft magazine are also included in this section. 3.8.1 drum reeler reeler where the paper web is wound onto a reel which rests on and is driven by a supporting cylinder (drum) whose peripheral speed is equal to that of the paper web Note 1 to entry: Figure 4 illustrates an example of a reel section with a drum reeler. 3.8.2 "open" reel section reel section without automatic roll handling where the parent rolls are handled with a crane 3.8.3 "closed" reel section
