TISSUE INDUSTRY

Introduction:

Roll covering material selection is essential for performance in the Tissue Industry.

Emboss roll 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 & design become more technically demanding to produce.  It is essential that the rubber Emboss roll continues to run at a stable temperature controlling the diameter and the pressure in the nip.  Hysteresis is lost energy resulting from repeated flexing & 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 & 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 Rolls

EmbossMaster I 45 – 70shore 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

Marriage Rolls

• MarriageMaster I 89 – 98 Shore A
• Excellent dynamic properties
• Excellent abrasion resistance
• Dual layer construction

Benefits include:

• Excellent cover life

• MarriageMaster II 89 – 95 Shore A
• Outstanding dynamic properties
• Outstanding abrasion resistance

Benefits include:

• Easy clean, reduced down time
