Glass Conveying

Glass Conveying

After years of development, IRP are now ready to manufacture their full range of 2540 series modular belting that is set to compete with its imported competition in both design and material specification. IRP will be producing the 2540 series in 3 material ranges

  • LF (Low Friction) Delrin Homopolymer Acetal (Grey )
  • XLF (Extra Low Friction) Internally lubricated, extra low friction Delrin Homopolymer acetal for improved wearlife. (Marine Green and Blue )
  • HPP Range ( High Performance Polymer – Black ) High performance engineered polymer formulated to withstand higher temperatures and increased wear properties.

The 2540 belting series will be most commonly used in the glass and bakery industries for glass conveying. The LF and XLF material range will be used quite extensively in the glass industry as this is where the focus of reduced wear and extra low friction will be of most benefit.

With IRP having specially designed the 2540 in a heavy duty 7.5″ TAB belt for the bakery industry and also specially formulating the material range HPP for higher performance in heat and wear applications has opened the market for IRP to replace heavier and more abrasive stainless chain to our lighter, quieter and more economic plastic HPP 2540 belt and chain series.

Plastic Materials

Glass Manufacturing is typically an environment where engineered plastic materials can help improve efficiency over standard material solutions. If the critical applications do not work reliably they will obviously bring down the overall productivity of the line. Due to the abrasive environment and the risk for broken glass and glass particles throughout the line, high performance materials can improve line efficiency and decrease down-time. Our special LF and XLF acetals offer high performance combining a low friction and good wear resistance. The tough wear resistant materials like our WRB and HPP composites can significantly improve 2540 Series lifetimes in comparison to standard acetals in combination with a smooth product handling. With our extended material portfolio IRP Engineering Plastics has the capabilities to supply materials for any specific application in glass manufacturing.

2540 Series – The 2540 Series belt have extended the possibilities to work with plastic products in a glass making environment. The fully closed and interconnected surface avoids broken glass getting stuck in between chains, but leaves the glass on top of the surface until it separates from the bottle flow at the drive. Using the 2540 series is a reliable solution for this environment even with the presence of broken glass accumulating at the sides of the chain. The use of Positrack guiding system ensures an optimum guiding of the chains over the full conveyor length.


Product Stability – The 2540 Series have improved the overall product handling on mass handling and single track conveyors. Covering the full width of the conveyor with one interlinked surface the 2540 Series belt range has virtually completely eliminated toppling of bottles on the chain surface. In combination with the Positrack guiding system the transfer from one conveyor to the other can also be optimized, almost eliminating gaps and therefore resulting in a optimum bottle handling and transferring.


Elevators/Lowerators – An important position in the glass manufacturing line is the bottle or jar elevator. The elevator makes sure there is a position in the line where people and fork lifts can easily pass, but also bring the bottles or jars to the packaging area. Furthermore you can combine these conveyors with blow-out devices to enable glass debris free bottles and jars. Elevators and Lowerators are standard equipped with roller chain based gripper chains. The difficulty in this area is the many different varieties in product diameter and shape which create changing requirements for the product handling. IRP Engineering Plastics offers a J-style ( 3 gripper fingers) to suit this application.


Curve Systems – The use of curve systems in Glass Making is common, plastic chains are being used more and more in these curves, both in single track and multiple track configuration. The use of curves reduces the pressure between the bottles when changing conveying direction and therefore reduces bottles damage and scuffing. IRP Engineering Plastics offer 3 different curve guiding systems from the traditional Bevel and TAB systems to the innovative Magnetic (Magnetic flex). All of these systems are being applied in Glass Making and offer specific advantages. Corner tracks are available in wear resistant Polyethylene, reinforced Polyethylene or lubricated Nylon materials, to suit different conveyor requirements in various positions of the line, speed required and chain materials used.
