2B603516 2.5-Layer Forming Fabric for Cultural and Specialty Paper — A forming fabric matched to the grade and drainage target
2B603516 is listed as a 2.5-layer, 8/16 shaft 2.5-layer forming fabric for cultural and specialty paper, in the 2.5-Layer family. Its construction and the dimensional values below are transcribed from the supplied product schedule. The listed air-permeability window is 4900 m³/m²·h (310 CFM). The application notes identify forming cultural and specialty papers. Review the forming or dryer-section layout, furnish, seam and operating conditions before specifying.

- The 8/16 shaft 2.5-layer design uses fine sheet-side support yarns, described as improving fines and filler retention.
- A locking double-warp bottom-weft design is specified for stability.
- Confirm furnish chemistry and retention targets before choosing the construction.
- Selection check: confirm the final machine position, dimensions and seam arrangement before ordering.

Applications
The supplied schedule lists forming cultural and specialty papers. For a dryer fabric, the position within a multi-cylinder dryer section matters because speed, contact conditions, sheet support and the desired air-flow window vary along the machine. For a forming fabric, the furnish, drainage demand, retention objectives and required sheet-side support should be reviewed together. The grade name alone is not enough to choose a construction.
Use the stated structure and yarn layout to shortlist the model, then compare it with the current fabric and the exact machine position. The available product information does not specify a guaranteed production result, service life or energy saving. Those outcomes depend on the operating system and must be assessed from the mill's own run data.
If this model is being considered as a replacement, share the paper grade, target basis weight, machine speed, fabric width, loop length, seam type and current permeability or forming data. The technical team can then verify whether the supplied schedule is appropriate or whether a position-specific variation should be discussed.
Selection Notes
Air permeability should be selected for the machine position, not from a generic product label. Where the schedule lists a range, the final target is configurable and must be confirmed against operating conditions. Where no value is listed, request the value for the proposed construction rather than inferring it from another model.
For an actionable quotation, provide machine speed, paper grade and basis weight, fabric width, loop length, current fabric model or construction, current air-permeability or drainage data, seam arrangement and machine position. Include any observed operating issue only if you have measured or documented it. This helps distinguish a construction change from a dimension or seam replacement.
Frequently Asked Questions
Is the air permeability fixed for 2B603516?
The supplied schedule lists 4900 m³/m²·h (310 CFM). Ask for confirmation if your operating target differs.
What information is needed for a quotation for 2B603516?
Provide paper-machine speed, paper grade and basis weight, fabric width, loop length, current-fabric details, seam requirement and the intended machine position. Values not included in the supplied schedule must be confirmed before ordering.
Can the listed specifications be changed?
Some constructions and permeability targets may be configurable, but the available design range depends on the machine and position. Treat the listed dimensions as the supplied reference and request written confirmation for the quotation configuration.
