Valmet's press felts are always tailor-made to the specifications of each individual board and paper machine and position: paper grade, furnish, speed, dimensions. The proven world class press felt manufacturing technology ensures that our press felts respond to the highest customer expectations. High quality Valmet Press Felts deliver results in terms of lifetime, energy savings, sheet dryness and reliability.
is especially designed for board machines. The felt features long lifetime and stable running. The felt has enough water handling capacity to avoid crushing and high CMD stability to avoid wrinkles and folding. The felt structure is optimal against marking.
This felt style is used in both center press and linear press concepts in all positions.
LMR is a laminated modular felt which is easily adjustable with relatively open base fabrics.
Open, heavy structures for slower machines with “dirt” conditions. The style is typically used in packaging grades linear press concepts in all positions.
The TMO/SMO felt delivers improved runnability and a fast start-up while enhancing nip dewatering. The Valmet TMO is an innovative press felt that combines the water removal properties of a conventional felt with the smoothness properties of a transfer belt.
The TMO manufacturing process impregnates polyurethane resin into the regular press felt structure. This special technology can be applied to endless felts (TMO) and to seam felts (SMO).
The safe, easy and quick installation of Valmet Press Felt TSM, a seamed felt, decreases the need of manpower and crane time. It is applicable fo all board and paper grades and felt positions. It has a double or triple layer structure with monofilament yarns and the void volume and openess are easily adjustable.
The SPM felt has relatively dense base stuctures for high nip dewatering. It starts up immediately, provides good runnability without any edge-related issues. It does not mark nor rewet, is stable thorughout its long lifetime. It is typically used in high speed printing and writing machines.
At best, long-term collaboration leads to mutual understanding and trust – as has happened between Perlen Papier and Valmet. As a result, Valmet was able supply Perlen Papier’s PM4 a full line of paper machine clothing for a trial run.
The special relationship between Ittihad Paper Mill and Valmet extends from supporting the establishment of the greenfield plant to delivering the mill’s entire production line. Valmet is also the sole supplier for paper machine clothing for the mill.
Press felts are key in successfully removing water in the papermaking process. Overall, they play a very important role in the machine’s performance, especially in terms of runnability. In press felts, small things make the difference. Valmet’s press felts are known by their profiling and special treatments.
