- Calendaring is a finishing process used in the manufacturing industry to create high-performance rubber, as well as other materials, for use in products such as gaskets, seals and O-rings.
- Calendaring is the process of making thin sheet of rubber and also lamination of such sheet on to other substrate like fabric, cord warp sheet by passing through set if rollers under controlled Conditions.
- Calendaring processes rubber by forcing the material softened by heat into the center of two to five counter-rotating rollers.
- The rollers compact the sheet as it passes through them.
- The thickness of the resulting product gets determined by the gap between the cylinders, called the nip region.
- Calendaring is a popular process because of its ability to precisely adjust the product thickness.
Benefits of Calendaring Rubber:
1. Control of thickness: Accurate rubber sheet gauge across the full length.
2.Frictioning operation for rubberized fabric
3.Skim coating and toping operation for rubberized fabric.
4. Smooth Finish: To obtain free of defect components like air bristles, rough surface. etc.
5. Increase Strength
Types of Calendar machines:
The rubber calenders are based on
1.The number of rolls
2.The position or orientation of the rolls.
The various rubber calender types are
Two roll horizontal type calender
Two roll vertical type calender.
Two Roll inclined or tilted type calender
Three Roll vertical type calender
ThreeRoll Offset stack calender
Four Roll Vertical Type calender
Four Roll Offser stack calender(Inverted L type)
Four Roll Offset Stack calender (S type)
Four Roll Offset Stack calender(Z type)
