Paper Machine Press Felt

Paper making felt include: Press felt, BOM felt, MG felt, Pick up felt, Shoe press felt, Combi Press Felt, Seamed felt. The paper making felt are of good adaptability, smooth surface, low steam consumption, long life and a fine water-filtering performance, which make the paper a superfine surface. Paper making felt Working Principle: In the press section of a paper machine, water is removed from the newly formed sheet. The paper sheet is carried by a press fabric between two rolls, where water is removed with the application of pressure. also can be assisted by the use of vacuum and heat.

Paper making felt Classification A press felt for the press or dewatering section of a paper machine is formed with an inner woven fabric and with a plurality of longitudinally extending, transversely spaced heavy yarns or strands which are supported on the bottom surface of the fabric by a relatively light cross-machine yarn or binder pick which interconnects the heavy strands with the warp yarns of the fabric. It is a kind of precious material in paper making industry. It can be divided into three types: wet felt, upper felt and dry felt according to the uses. There are Two series of paper making press felt available in the market, Endless Press Felt and Seamed Press Felt And Endless Press Felt could be divided in to some types according to the structure, Single Layer Felt, Double Layer, and Laminated Layer. Paper making felt Feature 1. High anti-compaction capacity. 2. Extremely high elasticity and recoverability. 3. Strong drainability abd larger void volumn. 4. Long holding time of wear resistance and plastic strength of felt. 5. Smooth felt surface and even pressure distribution.

Polyester synthetic forming fabric is a commonly used filter mesh in the forming section of paper machine, the forming wire can be divided into 1 layer, 1.5 layer, double layer, 2.5 layer, and triple layer forming fabric, in order to increase the work life of the polyester forming fabric, Huatao weaves the nylon monofilament with better abrasion resistance in the weft, which makes the fabrics life longer and reduces the cost. The 1.5 layer forming fabric is actually a 5-shed single layer forming fabric that have modified to have extra yarns which provides it the same properties as that of a double layer one. 1.5 layer forming fabric is easy to clean, increase sheet release as well as retention and with the extra fabric provides an excellent drainage.

1.Fourdrinier open headbox in paper making machine for sale is the key of paper machine,the function is supplying uniform and steady pulp flow to paper machine wire part. 2.The hydraulic headbox (hydraulic full-flow air-cushion combined headbox) is suitable for paper machine with a speed of 350-1500m/min and a speed of 1760-5500. The tube bundle enters the pulp stabilization chamber, and there is an attenuation chamber above the pulp stabilization chamber. It has an air cushion and spray device to eliminate air bubbles and reduce pressure pulses, and has an overflow outlet. The isobaric slurry flows from the stabilization chamber through the turbulence generator. Arrive at the upper weir plate of the convergence channel. 3.Air Cushion type headbox can increase the sizing pressure to meet the requirements of medium and high speed paper machines. The headbox consists of square taper tube device, evener roll device, top lip plate adjusting device, box body,control system, spraying device, air path system, etc.The headbox is designed with customer performance parameters, which can ensure work performance. 4.The Crescent paper machine adopts full stainless steel hydraulic headbox.The distributing bundle is combined with diffusion tubes.The diffusion tube bundle adopts the diffusion-finally section tube through the precise calculation, horizontal distribution and dispersion to the pulp which is from the inlet pipe so that the pulp has the uniform distribution effect and good dispersion characteristics, which guarantees the quality of tissue paper. Main Feature of head box: 1.Dedicated dilution water profile quantitative adjustment device can obtain better quantitative profile distribution; 2. High turbulence turbulence generator and special flap design can achieve better paper evenness; 3. Different designs are suitable for different vehicle speeds and paper types; 4. The addition of controllable edge flow to obtain good fiber orientation; 5. The upper lip plate adjustment mechanism of the structure can quickly and accurately adjust the quantification of the width; 6. The quick box opening design is convenient for maintenance and cleaning.

With many years of experience in production single layer forming fabric, can supply a wide range of single layer forming fabric. single layer forming fabric can meet many applications, if you need, please get our online timely service about single layer forming fabric. In addition to the product list below, you can also customize your own unique single layer forming fabric according to your specific needs.

Dryer screen design and materials are also very important. For a particular paper machine, the permeability, design and materials of the dryer screen should be adapted to make sure optimum drying from a drying section. The air permeability of the dryer screen has a great impact on the rate of evaporation of water. If the permeability is decreased, then it is reduction in drying capacity of the dryer screen. The dryer screen, whose air permeability range between 700-1000cfm is used on paper machine for producing higher gsm Kraft and board varieties. On the other hand 100-400cfm dryer screen widely used in medium and high speed paper machine, high numbers of contact areas with the drying surface ensure uniform drying. Proper chosen of dryer clothing improve paper machine runnability, increased drying rate, improved paper quality and savings energy.

Air Cushion type headbox can increase the sizing pressure to meet the requirements of medium and high speed paper machines. The headbox consists of square taper tube device, evener roll device, top lip plate adjusting device, box body,control system, spraying device, air path system, etc.The headbox is designed with customer performance parameters, which can ensure work performance.

Packing paper making felt apply to all types of large-diameter roll press, shoe press and pick-up high-speed paper machines to produce different kinds of packing paper of 70 to 400 grams. The endless weaving technique with a full set of imported raw materials and equipments for production lines ensures the stability of the base fabrics and the smooth surface of the felts. This kind of products improves the start-up speed of paper machines and they can withstand high temperatures and other adverse machine conditions.

The 1.5 layer forming fabric is actually a 5-shed single layer forming fabric that have modified to have extra yarns which provides it the same properties as that of a double layer one. 1.5 layer forming fabric is easy to clean, increase sheet release as well as retention and with the extra fabric provides an excellent drainage. The ideal 1.5 layer forming fabric for most paperboard and packaging grades applications, especially where a smooth top surface and long life potential are desired. In addition, Clean mesh yarn technology provides maximum resistance to premature fabric contamination. Polyester 2.5 layer forming fabric are also known as support shute double layer forming fabric or double layer extra designs. It's a standard double layer design with an extra shute yarn added on the forming side between the 2 regular cross direction yarns. This yarn increase the pulp fibre support and meanwhile create a more open structure as the amount of wear side yarns is reduced, compared with the forming side. 2.5 layer forming fabric's weaving effect greatly increases the fiber support index due to the addition of a fine weave at the top. The ratio of the top and bottom wefts is 2:1. It suitable for paperboard,newsprint,writing paper,tissue paper,printing paper,kraft paper. The SSB 3 layer forming fabric or "wire" of a paper machine is the continuous belt or belts of mesh screen upon which the paper sheet is formed. Most modern SSB 3 layer forming fabric are comprised of polyester monofilament. The weave pattern and layering of a SSB 3 layer forming fabric is designed to meet stringent requirements of dimensional stability, resistance to abrasion (on the wire side), minimum resistance to drainage, minimum wire-mark, and (sometimes) maximization of retention of fiber fines.
