BOM Press Felts — Structure, Function, and Selection

Base mesh + fiber batt + needle-punching + heat setting — the BOM construction delivers consistent dewatering, smoothness, and long press felt life across all press positions

Press felts are critical paper machine clothing in the press section, responsible for three simultaneous functions: water removal (dewatering the wet paper web to increase dry content), sheet smoothing (providing a surface against which the paper is pressed), and web transport (carrying the paper sheet from the forming section to the dryer section). The choice of press felt directly affects paper dry content after pressing, paper surface quality, energy consumption in the dryer section, and felt running life.

PFM SCREEN's BOM (Base + Over + Monofilament) press felts are constructed from a base mesh layer of monofilament or composite synthetic yarn, overlaid with multiple layers of nylon or polyester staple fiber batt, then bonded by needle-punching and stabilized by heat setting and special post-finishing. The SMO (Smooth surface, Mark-free Operation) surface treatment ensures no lint release and mark-free paper surfaces from the first moment of use.

Available in single, double, and triple base mesh layer configurations (plus multi-axial laminated and seamed options), PFM SCREEN press felts can match any press type — from straight-through nip presses to vacuum suction presses, groove presses, large-diameter roll presses, and shoe presses.

BOM Press Felt Layer Structure — Single, Double, and Triple Base Mesh

Each additional base mesh layer increases the felt's NIP resistance, void volume, and tensile strength — enabling compatibility with progressively higher press pressures

Single Layer BOM

GSM 700-1200 · NIP ≤80 kN/m

One base mesh layer with multi-weight nylon fiber batt layers overlaid. Lowest weight, highest air permeability. Ideal for first press positions and lower-speed machines.

Double layer BOM press felt 1+1 composite structure

Double Layer BOM (1+1)

GSM 950-1450 · NIP 60-200 kN/m

Two base mesh layers of different thicknesses. Larger void volume, better compression resistance, and excellent resistance to vacuum marks — suited to groove and suction press positions.

Triple layer BOM press felt 1+2 composite structure shoe press

Triple Layer BOM (1+2 / 1+1+1)

GSM 1450-1750 · NIP ≥200 kN/m

Three base mesh layers (1+2, 2+1, or 1+1+1). Maximum void volume, highest tensile strength (≥4500 N/5cm), full mark elimination — for shoe press and high line-pressure positions.

All structures are finished with needle-punching + heat setting + SMO (Smooth surface, Mark-free Operation) surface treatment. Contact us to select the right base mesh configuration for your press section.

PFM SCREEN's full range from single-layer BOM for basic press positions to advanced multi-axial laminated and seamed press felts for demanding applications

Single layer BOM press felt paper machine clothing

Single Layer BOM Press Felts

GSM 700-1200 · NIP ≤80 kN/m

Best for: First Press Position · Lower-Speed Machines · ≤800 m/min

Single Layer BOM Press Felts

The most basic BOM press felt design, comprising a single-layer base mesh fabric overlaid with multi-weight nylon staple fiber batts, needle-punched and heat-set for dimensional stability. Available in four sub-types: Single Layer Forming BOM, Single Layer Press BOM, Single Layer Top BOM, and 1.5 Layer BOM. Performs well in first press positions on cylinder, Fourdrinier, inclined wire, and nip wire paper machines. Low elongation (≤1%), easy to clean, no paper surface marking, and compatible with machines running paper grades from tissue (≥8 g/m2) up to standard printing and packaging paper.

Double layer BOM press felt printing paper newsprint

Double Layer BOM Press Felts

GSM 950-1450 · NIP 60-200 kN/m

Best for: Vacuum Suction Press · Groove Press · Multi-Nip Press · ≤1000 m/min

Double Layer BOM Press Felts (1+1 Composite or Double MD Yarn)

Two base mesh configurations: 1+1 composite (two base meshes of different thicknesses) or double MD yarn structure. The double-layer design delivers significantly higher press resistance, better flexibility, larger void volume, and superior dimensional stability compared to single-layer felts. Excellent resistance to vacuum marks, blind hole marks, and groove marks — essential for groove press and vacuum suction press positions. Used to produce high-grade printing papers, newsprint, technical papers, packaging papers, and high-grade paperboards on medium and high-speed machines.

GSM: 950-1450 g/m2 · Air Perm: 30-110 CFM · Tensile: ≥3000N/5cm · Elongation: ≤0.6% · NIP: 60-200 kN/m

Triple Layer BOM Press Felts

GSM 1450-1750 · NIP ≥200 kN/m

Best for: Shoe Press · Large-Roll Press · High Line Pressure · ≤1000 m/min

Triple Layer BOM Press Felts (1+2, 2+1, or 1+1+1 Composite)

Three composite base mesh structures (1+2, 2+1, or 1+1+1) deliver the highest felt thickness, tensile strength, and void volume available in BOM construction. Adapts to NIP pressures above 200 kN/m with high elasticity, excellent water filtration, reliable mark elimination, and dimensional stability under extreme press loading. Suited for vacuum compound press, large-roll blind-hole press, and shoe press on medium and high-speed machines producing high-grade newsprint, writing paper, board, and technical papers. Longest service life in the BOM range.

GSM: 1450-1750 g/m2 · Air Perm: 40-90 CFM · Tensile: ≥4500N/5cm · Elongation: ≤0.6% · NIP: ≥200 kN/m

Multi-axial laminated press felt high dehydration shoe press

Multi-Axial Laminated Press Felts

Cross-Directional Base Mesh · Maximum Compaction Resistance

Best for: High-Dehydration Press · Long Felt Life · All Paper Types

Multi-Axial Laminated Press Felts

An advanced press felt construction in which base mesh layers are arranged in multiple directions and angles relative to the felt's machine-direction running axis. When superimposed in 1+1 or 1+1+1 configurations, the angular base meshes resist mutual crushing and compression permanently — resulting in significantly higher resistance to compaction than conventional laminated felts, a higher degree of consistent void volume, superior flatness resistance, and sustained water permeability throughout the entire felt life. Lower steam consumption and higher dehydration in the press section are direct operational benefits. Suitable for all paper and board types.

Applications: all paper and board types · Advantage: compaction resistance + consistent dewatering + long life

Seamed Press Felts

Easy Installation · Mark-free Seam · Reduced Downtime

Best for: Restricted Access Positions · Fast Changeover · All Paper Grades

Seamed Press Felts

Seamed (open-end) press felts allow significantly safer and faster installation compared to endless felts, reducing the labor, crane time, and machine downtime required for felt changes. PFM SCREEN's seamed press felts feature a strong, mark-free seam area constructed with interlocking warp threads and seam ring units joined by core wires — delivering durable seam integrity at full press loading. Available in double or triple base mesh construction with adjustable void volume and openness. Suitable for all paper and board machines using virgin or recycled fiber. An important option when machine design restricts endless felt installation.

Applications: all paper/board grades · Virgin or recycled fiber · Double/triple base mesh available
