Roller covering material selection is essential for performance in the Tissue Industry.
Emboss roller coverings must exhibit minimal heat build-up characteristics (low hysteresis) and excellent rebound resilience. Both are essential as line speeds increase and emboss patterns by depth and design become more technically demanding to produce. It is essential that the rubber Emboss roller continues to run at a stable temperature controlling the diameter and the pressure in the nip. Hysteresis is lost energy resulting from repeated flexing and deformation. An emboss cover with low hysteresis properties will expend the energy to pass the rubber into and through the nip then completely recover in preparation to re-enter the nip. Excellent rebound resilience properties enable the rubber Emboss to push deep into the pattern providing true pattern replication and glue strike.
Martland Rollers are able to offer three grades of emboss cover that exhibit these characteristics namely EmbossMaster I, EmbossMaster II and EmbossMaster III
Embossing Rollers
EmbossMaster I 45 – 70 Shore A
An Emboss cover with low hysteresis for cool running, excellent physical properties (modulus & tear strength) and excellent abrasion properties.
Benefits include:
- Precise pattern definition
- Exceptional cover life
EmbossMaster II 45 – 70 Shore A
For the convertor producing a diverse product range with multiple pattern changes or lines producing both toilet paper and kitchen towel. The Emboss cover has a greater elasticity providing greater resilience combined with excellent abrasion and mechanical strength.
Benefits include:
- Versatility to change between products that have a wide range of pattern heights & complexities
- Extended cover life
EmbossMaster III 45 – 70 Shore A
For the convertor who needs an Emboss cover with outstanding resilience to enable ultimate control within the nip through the reduction of the nip width & nip pressure to facilitate precise pattern replication and glue strike through whilst maintaining the papers strength.
Benefits include:
- Cost savings provided by increased tonnage from cold start up and up-sheeting savings from improved bulk tonnage and log firmness
- Improved product quality with precise pattern replication and enhanced final product strength
ApplicatorMaster I 65-70 Shore A
Surface finish 0.8 Ra
Superb superior glue transfer
ApplicatorMaster II 65-70 Shore A
Surface finish 0.8 Ra
Exceptional abrasion properties
Benefits include:
- Improved glue transfer
- Outstanding cover life
- Reduced down time & glue wrap rounds
- Reduced fibre pick-up and glue contamination
