SSB Triple Layer

3CSSB404520 SSB Triple-Layer Forming Fabric for Packaging Grades — A forming fabric matched to the grade and drainage target

3CSSB404520 is listed as a ssb triple layer, 2+10 shaft ssb triple-layer forming fabric for packaging grades, in the SSB Triple Layer family. Its construction and the dimensional values below are transcribed from the supplied product schedule. The listed air-permeability window is 5500-7580 m³/m²·h (348-480 CFM) and is configurable for the machine position. The application notes identify low-basis-weight corrugating medium and kraft packaging paper; the data also lists use as a middle ply in a multi-ply forming arrangement. Review the forming or dryer-section layout, furnish, seam and operating conditions before specifying.

Key Features

  • A 2+10 shaft SSB structure is specified with a 3:2 weft ratio.
  • The plain-weave sheet side is described as supporting sheet release and limiting wire marks.
  • Coarse weft and twill wear-side construction provide a long-span wear design as stated in the supplied data.
  • Selection check: confirm the permeability target and test basis for the exact machine position.

Applications

The supplied schedule lists low-basis-weight corrugating medium and kraft packaging paper; the data also lists use as a middle ply in a multi-ply forming arrangement. 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

What machine positions is 3CSSB404520 listed for?

The supplied application notes list Low-basis-weight corrugating medium and kraft packaging paper; the data also lists use as a middle ply in a multi-ply forming arrangement. Final suitability depends on the actual machine position and operating conditions.

Is the air permeability fixed for 3CSSB404520?

No single value should be assumed. The supplied schedule gives 5500-7580 m³/m²·h (348-480 CFM) as a configurable range; confirm the target for the exact position.

What information is needed for a quotation for 3CSSB404520?

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.
