No matter what forming section! No matter what paper grade! No matter what machine! With Primoselect Heimbach offers you an innovative forming fabric, which combines optimum drainage with the best runability. The foundation for this is an innovative weave concept, which is unique on the market.
Primoselect paves the way for unexpected flexibility: the special weaving pattern allows options to suit your specific wishes. You can choose between:
SSB forming fabric woven using 24 harness technology, which allows 6 shaft machine side construction to promote improved life potential. Available with 2 or 3 shaft paper side construction and 3:2, 2:1 or 1:1 weft ratio. Duralon, a patented machine-side weft material, is also available in Primobond designs to further improve life potential and reduce power consumption. The Primobond family has options in HD, F, SF or XF depending upon application or paper grade. The XF design benefits from Stabilon high modules machine direction yarns which promote high FSI without compromise to dimensional stability. A Primobond specification should be available to clothe all former types making all paper grades.
Double layer fabrics in 8- or 16- shaft construction with optional extra weft technology on the paper side. Duralon, the patented machine side weft material, is also available as an option to promote increased life potential and reduced energy consumption. Primoplan fabrics can clothe all former types making all papergrades.
Atrojet is the unique press felt with a highly flexible, adaptable multiaxial non-woven module:
Tissue press felts are sophisticated products:
The tailored adaption and outstanding features of Atrojet press felts make them ideal for use in tissue production.
The base of Atrocross is composed of non-woven substrate layers positioned flat on top of one another both in the cross-direction and in the machine direction. The fast start and the good dewatering of Atrocross can be explained by the combination of three significant constructional features:
Atrocross - non-woven technology for high-speed machines producing printing and writing paper grades - "the" standard for shoe presses. Different designs cater for different application requirements by adjustments to the modular structure / construction.
Atromaxx – the multiaxial module concept from Heimbach distinguishes itself by the selected combination of warp knitted and woven single base layers adapted to the specific demands of press configuration and paper grade. The wide range of combination possibilities provided by the modular construction technique enables fine adjustment to individual positions. Atromaxx is also available with seam.
With yamabelt. Heimbach offers another product for application within the shoe presses. Against former times when shoe press belts had been regarded as roll covers this point of view has changed dramatically in the past few years. Heimbach has recognized this trend and it was possible to win a competent partner across the dewatering processes of a shoe press with Yamauchi as producer of the yamabelt.
With implementation of Yamauchi´s KnowHow into adequate belt designs and the proven (dewatering) strengths of Heimbach press felts in shoe presses it was possible to combine both products into a package that positively influences the efficiency and runnability of shoe presses.
Yamabelt. provides excellent mechanical and chemical resistance by the use of a complete new family of Polyurethanes. New and patented solutions of edge relief designs prevent from the well known problems of belt cracks especially in the shoe edge areas of the pressbelts. As well the doctoring of the shoe press belt is being optimized by means of a special surface treatment of the Polyurethane within the grooves. With this solution higher dry contents after the press section can be obtained.
In summary it can be stated that by common installation of a yamabelt. as well as a adequately designed Heimbach press felt a perfect symbiosis for best press runnability will be created.
