Ceramic lagging manufacturing process for large rolls is more efficient and requires less tooling set up and change – as a result costs are reduced.

Limitations of ceramic lagging strips cut to size.

Traditionally, pulley lagging has been supplied in cut to size strips that match the pulley face length. This method requires the customer to stock a specific lagging strip length for each pulley size or place an order for each specific job which is translated in considerable lead times. Figure #1 shows a standard ceramic lagging strip with rubber ends cut to size and the ceramic length matched to the belt width.

Elastotec developed the technology and equipment to manufacture lagging in large rolls. This includes:

  • a ceramic lagging design that can be cut to suit many pulley face widths
  • a hot vulcanised joining system
  • handling and packing equipment for large rolls

Lagging supplied in rolls has 10 mm of rubber between tiles that allow the roll to be cut at any point between tiles. Following the Elastotec application procedures it is possible to make the strip cut from the roll to match the length of many different pulley face widths.

Rolls require minimum stock as only one roll for dimple lagging and one for plain lagging of each thickness need to be stocked. Because the roll can be cut to size to pulley face length, lagging is no longer made for a specific pulley face length. This gives the customer the possibility to reduce lead times.

Figure #2 above shows the design for lagging supplied in rolls.

Key features and benefits

One size fits all

Lagging rolls can be supplied up to the following sizes:
