Gypsum Board Industry

Gypsum Board Industry

Gypsum Industry Process

1. Forming Belt

1. Forming Belt

The forming belt is the most sensitive but equally most important component in the entire production process. It both starts and lies at the heart of the production process. The wet gypsum mixture is formed and hardened on it as a flat endless sheet between two layers of heavyweight paper.

Gips - Forming Belt

Technical Requirements of the belts

To manufacture high-quality plasterboard, the surface quality of the belt has to be superb, its thickness across its entire width, length and splice precise, it needs to track absolutely straight and have a low friction coefficient. These superior belts stand apart for their long service lives but consistently retain the above-mentioned characteristics at the same time. Should minor damage to the belt’s surface occur, it needs to be put it right quickly, easily and efficiently.

Our Solution

Forbo Movement Systems E 20/2 V28/V28 MT/MT grey forming belt is an excellent solution with an outstanding track record worldwide. A double-ply high-tech fabric tension member made of extremely robust and special exceptionally laterally stiff polyester fabric with low elongation makes the forming belt an innovative option. The maintenance-free belt is successfully ousting the thick rubber and PVC belts frequently used in the past.

Characteristics, Functions and Benefits

The PVC belt is 9 mm thick and in addition to its exemplary tracking capabilities and highly accurate thickness tolerance, it’s also very hard wearing and laterally stiff. The belt complies with all requirements. Thanks to its physical characteristics, it can be fitted to virtually any machinery without requiring many modifications in just two days, even if the conveyor was originally conceived for rubber belts.

2. Taper Edge Belt

2. Taper Edge Belt

Taper edge belts form the edge shape of certain plasterboards so that these can subsequently be filled on construction sites. They are placed onto the forming belt on both edges of the panels. Taper edge belts are available in virtually all shapes.

Gypsum - Taper Edge Belt
Gips - Taper Edge Belt

Technical Requirements

The shape of taper edge belts should of course match the customer’s production portfolio. Depending on the panel type made, they need to be integrated into the process and removed again without requiring any extra tools. In this case, flexibility and speed have top priority.

The undersides of the taper edge belts should be as soft as possible so that they don’t damage the forming belt underneath. Even if they have long service lives, it’s imperative that taper edge belts maintain their dimensions and don’t elongate.

Our Solution

With total thickness of 2 mm, the fabric-reinforced Siegling Transilon E 6/1 V1/V14 MT-NA white is perfect for these process requirements and guarantees the flexibility required. The belts lie completely flat and keep their shape superbly.

A soft underside of Forbo Movement Systems’ taper edge belts has a fabric that protects the surface of the forming belt to extend its service life. The reinforced belts don’t elongate and can be made endless thanks to straightforward splicing technology.

3. Roller Drive Belts

3. Roller Drive Belts

Board conveying is inconceivable without roller drive conveyors. At this step of the process, the roller drive belts have to be fast, reliable and efficient.

Gypsum Roller Drive Belts

Technical Requirements

Here, it’s crucial that the drive component is reliable and maintenance-free in terms of material flow and board conveying despite the high speeds involved.

Gips - Roller Drive Belts
Test-Gips

Our Solution

We’ve developed a range of roller drive belts especially for this application. The combination of tension member and coating gives these belts their special characteristics tailored to the conveyor type and application. As the coating material, highly elastic elastomer or polyurethane ensure seamless and dependable power transmission.

The belts offer unbeatable advantages: durable underside with constant grip; constant tension regardless of temperature and climate (aramide and polyester line); superior flexibility but superb strength at the same time; low power losses due to less creep and little downtime due to fast fitting. All these advantages guarantee long service lives but economical and maintenance-free belts.

4. Transfer Belts

4. Transfer Belts

Transfer belts move panels, but can also be used in various processes such as cross conveying, board flippers, dryer in-feed and out-feed sections, stacking and warehousing. They usually run in parallel in a set.

Gypsum Transfer Belts
Gypsum Industry Process

Technical Requirements

Whether the plasterboards are conveyed horizontally or diagonally, the belt’s top face must be able to guarantee reliable, non-slip conveying, especially in the wet section in front of the dryer channel. The belts must be able to position the panels exactly without them slipping.

Our Solution

Forbo Movement Systems offers perfect belts for this challenging task. The types of surface, e.g. with suitable patterns, play a key role in conveying the panels reliably. As a result, unnecessary waste is avoided due to the panels slipping. The surface of the top face means the panels are positioned exactly and the edges protected.

5. Stack Conveyor Belts

5. Stack Conveyor Belts

Heavy live rollers or plastic modular belt conveyors are primarily used for conveying piles of boards usually conveyed horizontally. Special heavy-duty belts with appropriate characteristics allowing them to operate in tough conditions are required.

Gypsum 5
Gypsum Industry Process

Technical Requirements

In addition to positioning the pile precisely, the belts must be able to convey the boards reliably and so that they don’t slip. As heavy forklift trucks convey the piles elsewhere, the conveyors and the associated belts need to be extra hard-wearing.

Our Solution

Forbo Movement Systems’ belts for this step in the process specialize in conveying heavy goods. Robust and exceptionally durable belts from the Siegling Transtex product range can for example drive heavy live rollers.

The Siegling Transtex belts keep to their dimensions, are flexible, quiet and can withstand moisture and chemicals. They’re easy to make endless, allow simple conveyor designs and stand apart for their low energy consumption.
