Texo is currently seeing a surge in demand for its custom made weaving looms for press felt base fabrics. Compfelt weaving machines from Texo AB, Älmhult/Sweden, a member of the Swedish Textile Machinery Association (TMAS), Stockholm/Sweden, are specifically employed for the production of endless (tubular) woven base fabrics for the press section of paper machines, where water is mechanically removed from the newly formed sheet of fibers. The PMC fabrics here need to be replaced regularly, with a maximum lifespan of 6 months.
Press felts consist of complex woven base structures which are subsequently combined with nonwovens through needlepunching. An endless woven fabric produced on a recently delivered 23-m-wide machine makes endless fabric belts of 46 m. The machine can be adjusted in steps to create smaller belts as required. These looms operate at between 30 to 55 picks/min. with shuttles that are almost 1 m long. They have a max. warp tension of 1,500 kg/m and a max. beat-up tension of 3,000 kg/m.
The machine can be equipped with up to 24 dobby harness frames to meet the demand for sophisticated structures from the PMC manufacturers. Although the PMC business represents a small proportion of the total cost of manufacturing paper, it can have a significant impact on the quality of the paper, the efficiency of a machine and machine production rates. As technology moves forward, the company is also currently very active in the retrofitting of existing machines built as far back as the 1970s. The machines out in the market are still supported with Texo mechanical spare parts. They can, however, also be equipped with the latest technology for automation. With new controls, drives and motors they can perform as well as the latest machines.
The company has also just integrated its offices and production center at its base in Älmhult to create a unified 5,000 m² site. The new office is built with an open Scandinavian design and has all of the latest technologies required for a sustainable and environmentally friendly workplace, including a solar paneled roof.
»Paper is replacing plastic in many areas, and we see new as well as retrofit investments in many places. The ability to upgrade textile machinery to the latest technology using controls and drives is something I expect to see a lot more of.«
