Definitions

  • Paper machine especially a tissue paper machine
  • the present invention relates to the technical field of paper making and especially tissue paper making and the field of the paper machine itself.
  • tissue paper is to be made out of pulp, the process essentially comprises
  • a forming that includes the headbox and the forming wire section
  • the drying section (TAD (through air drying) ) or conventional drying on a yankee cylinder) that also usually includes the crepe process essential for tissues,
  • c typically the monitoring and winding section.
  • Paper can be formed by placing the fibers, in an oriented or random manner, on one or between two continuously revolving wires of a paper making machine while simultaneously removing the main quantity of water of dilution until dry-solids contents of usually between 12 and 35 % are obtained.
  • Drying the formed primary fibrous web occurs in one or more steps by mechanical and thermal means until a final dry-solids content of usually about 93 to 97 %.
  • tissue making this stage is followed by the crepe process which crucially influences the properties of the finished tissue product in conventional processes.
  • the conventional dry crepe process involves creping on a usually 4.5 to 6 m diameter drying cylinder, the so-called yankee cylinder, by means of a crepe doctor with the aforementioned final dry- solids content of the raw tissue paper (wet creping can be used if lower demands are made of the tissue quality) .
  • the creped, finally dry raw tissue paper (raw tissue) is then available for further processing into the paper product or tissue paper product according to the invention.
  • TAD through air drying
  • the fibrous web is supported by an air-permeable wire or belt (or TAD-fabric) and during its transport is guided over the surface of an air-permeable rotating cylinder drum (TAD-cylinder) .
  • TAD-cylinder air-permeable rotating cylinder drum
  • Structuring the supporting wire or belt makes it possible to produce any pattern of compressed zones broken up by deformation in the moist state, also named moulding, resulting in increased mean specific volumes and consequently leading to an increase in bulk softness without decisively decreasing the strength of the fibrous web.
  • Such a pattern is fixed in the area of the TAD-cylinder.
  • a tissue paper is defined as a soft absorbent paper having a low basis weight.
  • the total basis weight of multiple-ply tissue products is preferably equal to a maximum of 65 g/m 2 , more preferably to a maximum of 50 g/m 2 .
  • Its density is typically below 0.6 g/cm 3 , preferably below 0.30 g/cm 3 and more preferably between 0.08 and 0.20 g/cm 3 .
  • tissue is distinguished from paper production by the its extremely low basis weight and its much higher tensile energy absorption index (see DIN EN 12625-4 and DIN EN 12625-5) .
  • Paper and tissue paper also differ in general with regard to the modulus of elasticity that characterizes the stress-strain properties of these planar products as a material parameter.
  • a tissue's high tensile energy absorption index results from the outer or inner creping.
  • the former is produced by compression of the paper web adhering to a dry cylinder as a result of the action of a crepe doctor or in the latter instance as a result of a difference in speed between two wires ("fabrics"). This causes the still moist, plastically deformable paper web to be internally broken up by compression and shearing, thereby rendering it more stretchable under load than an uncreped paper.
  • Moist tissue paper webs are usually dried by the so-called Yankee drying or the through air drying (TAD) .
  • TAD through air drying
  • the fibers contained in the tissue paper are mainly cellulosic fibres, such as pulp fibers from chemical pulp (e.g. Kraft sulfite and sulfate pulps), mechanical pulp (e.g. ground wood) , thermo mechanical pulp, chemo-mechanical pulp and/or chemo-thermo mechanical pulp (CTMP) . Pulps derived from both deciduous (hardwood) and coniferous (softwood) can be used. The fibers may also be or include recycled fibers, which may contain any or all of the above categories. The fibers can be treated with additives - e.g.
  • tissue paper may also contain other types of fibers, e.g. regenerated cellulosic fibres or synthetic fibers enhancing, for instance, strength, absorption, smoothness or softness of the paper.
  • Tissue paper may be converted to the final tissue product in many ways, for example, by embossing or laminating it into a multi-ply product, rolled or folded.
  • Such products may be paper towels, paper napkins, paper handkerchiefs, facials etc .
  • the detector there exists not only a possibility to remove formation of the fiber sparks but to store the corresponding mother roll separate from the mother roll storage in a safe area at least for a safety while.
  • the spark detector is provided downstream the yankee cylinder where most probably sparks may appear.
  • cleaning air jet means is provided, wherein the air jet thereof is directed to the spark detector.
  • the spark detector is combined with a web run-guiding means stabilising the web run. There the spark detector is positioned close to the running paper web so that sparks safely can be detected.
  • the web run- guiding means comprises at least one guiding surface behind which a space is provided surrounded at least partly by a casing, in which an air-inlet-opening is provided such that air sucked in by an under pressure created by the web run is directed to the spark detector for cleaning purposes .
  • this system may be combined with a cleaning air jet means.
  • a preferred location for the spark detector is downstream a web measuring means, where basis weight and water content of the web is measured. This is a place where paper web- stabilisation can be kept as short as possible and no other means has to be installed there.
  • the spark detector remains clean and it is not necessary to take care for special cleaning for which the machine run would have to be interrupted.
  • spark detector for instance between the yankee cylinder and the winding-up section a good paper web stability is maintained.

  • Fig.l is schematically illustrated a tissue paper machine comprising a headbox 1, a forming section 2 a drying section 3 and a winding-up section 4.
  • Reference number 5 denotes a forming fabric and the reference number 6 downstream thereof a felt guiding the paper web W from the forming section 2 to the drying section 3.
  • There is a pick-up roll 7 transferring the paper web from the forming section 2 to the felt 6.

  • Especially such sparks may be present and created when fiber material possibly combined with dust and paper lumps probably combined with the chemical agent by which the yankee-cylinder is coated fill the space between the dryer hood 10 and the yankee-cylinder 9. This result in friction, which could cause higher temperatures leading to the fiber sparks.
