Paper machine press felt selection
Press felts combine a base fabric with needled batt layers. The construction is selected for the press position, nip arrangement, dewatering and installation conditions. Hengfeng offers press felt capabilities; individual materials, dimensions and supply specifications require confirmation against the actual machine.
BOM press felt
A batt-on-mesh construction is reviewed for the intended press position and water-handling requirements. Provide the position, nip arrangement, paper grade, speed, existing felt construction and observed operating issues.
Laminated press felt
A laminated base construction can be evaluated for a press position where the base arrangement needs review. Provide machine layout, nip load, present base construction, available installation space and service observations; suitability depends on actual conditions.
Needle felt construction
Needled batt and base construction must be evaluated together for the intended press position. Provide the current batt and base description, felt weight and thickness if known, paper grade, cleaning practice and any marking or dewatering concerns.
Seamed press felt
A seamed option is considered where the press position and installation procedure permit a seam. Provide machine-builder constraints, seam orientation, pin or joining requirements, access and current seam observations; compatibility must be confirmed before ordering.
Specification dimensions to confirm
- Base fabric layers and construction
- Needled batt composition and arrangement
- Finished weight and thickness, when measured
- Air permeability with test method and conditions
- Seam and installation requirements
- Press position and dewatering arrangement
Information for a felt review
Share measured or documented information; unknown values may be left blank.
- Paper grade and basis-weight range
- Machine speed and press position
- Nip arrangement and dewatering equipment
- Finished width and endless length
- Existing felt construction and seam
- Cleaning practice and observed problems
Frequently asked questions
Can one felt construction suit every press position?
No. Review the nip, dewatering arrangement, paper grade and installation constraints for each position.
Can a seam be added to any press felt?
Seam suitability depends on the machine layout, press position and installation requirements and must be confirmed for the actual machine.
Are fixed model specifications available?
No model-specific values are stated here. Confirm construction, dimensions and testing conditions in a written specification.
No model-specific performance or dimensions are claimed here. All parameters and applicability require confirmation for the actual operating conditions.
