Centring units for conveyors

Tentoma offers various options for its RoRo StretchPack® packaging machine, allowing the complete packaging solution to be tailored to the specific product and production line. These options ensure high-quality packaging at high capacity, with the centring unit being a prime example.

The centring unit is designed to align products on the infeed conveyor, ensuring they are perfectly centred before entering the RoRo StretchPack® packaging machine. This precise alignment guarantees a seamless packaging process, which is essential for optimising packaging capacity.

This video showcases different centring units designed for various types of conveyors, including:

  • Roller conveyor
  • Flat conveyor belt
  • Modular belt conveyor
  • Dual belt conveyor

Comparison of packaging methods

It is essential to choose the right packaging technique to have an efficient packaging process and to achieve the optimal packaging quality to protect your product.

When selecting packaging for your product, multiple techniques are available, each with its own strengths. It is essential to consider the purpose of the packaging to ensure the best fit.

For packaging building materials, large rolls, and similar products, packaging solutions such as orbital wrapping, sleeve wrapping, heat shrink packaging, and RoRo StretchPack® are commonly used.

Below you will find a comparison of different techniques (orbital wrapping / sleeve wrapping / heat shrink packaging / RoRo StretchPack®) typically used for packaging of rolls, building materials and similar:

5 ways to improve insulation packaging

Flyer: 5 ways to improve insulation packaging

Using a RoRo StretchPack® packaging solution, you will get a packaging solution that perfectly fits insulation packaging. First of all, it utilizes a stretch hood film to create a 6-sided package that is 100% sealed and waterproof. But there are more reasons. 

In this small flyer, we have listed “5 ways to improve insulation packaging with RoRo StretchPack®.” Click below to read the full flyer.

Air shaft simplifies changing film rolls

The film stand for the RoRo StretchPack® packaging machines can
optionally be equipped with an air shaft to hold the film roll. An air shaft is a convenient solution that allows for quick and easy film roll changes.

The integrated measuring tape makes it easy to centre the film roll on
the air shaft. Fixing the roll quickly and efficiently using compressed air, while releasing the film roll is as simple as pressing the air valve.

Using a compressed air pistol, the air shaft expands and secures the film roll instantly.
To release the film roll, press the air valve, which causes the air shaft to contract.
The air shaft can be used with all types of film stands for the RoRo StretchPack® packaging machines. The zero mark on the integrated measuring tape indicates the centre of the air shaft, making it easier to centre the film roll.

Packaging single-panel using centring unit

In this video, you will discover the advanced capabilities of the RoRo StretchPack® packaging machine for single-panel packaging, which is 100% waterproof.

This packaging machine is enhanced with an optional centring unit on the infeed conveyor. This video demonstrates a test packaging with a single panel, showcasing how the centring unit ensures an optimal packaging process by aligning and centring products before the packaging begins.

The centring unit lifts the product from the dual belt conveyor, straightening and centring it on the conveyor. Following this, the packaging process starts. The panel moves horizontally into the opening of the tubular stretch hood film. During the packaging, the stretch hood film is sealed at both ends, creating 100% waterproof packaging. This means that packaging and sealing are done in the same process.

Movable bridge conveyor for products with cross stringers

Packaging products on skids or pallets with cross stringers using stretch hood film requires a movable bridge conveyor to ensure an uninterrupted process. Without it, the gap between the infeed and outfeed conveyors in the packaging machine can cause stringers to fall, leading to disruptions and compromised packaging quality.

The bridge conveyor eliminates this issue by providing a stable, continuous path for the product. Integrated with the RoRo StretchPack® system, it ensures precise alignment as the product moves into the stretch hood film, delivering secure and high-quality packaging.

This fully automated process includes loading, applying, and sealing the stretch hood film. Excess film is cut and collected for recycling, offering an efficient and sustainable packaging solution. The result is a waterproof six-sided packaging that protects the product and enhances its appearance.

Watch the video to see how the bridge conveyor enables seamless six-sided packaging of skids using the RoRo StretchPack® machine.

Simplifying the strapping workflow

You can unlock additional operational efficiencies by incorporating a bridge conveyor into your packaging line. A movable bridge conveyor allows for the integration of securing spacers and bearers beneath your products within the packaging workflow.

A RoRo StretchPack® solution with a movable bridge conveyor can include spacers and bearers within the stretch hood film. The film’s tension ensures that the spacers remain firmly in place, providing stable, smooth packaging without the need for strapping. This eliminates the need for dedicated strapping machinery for certain products, simplifying your packaging line and reducing operational complexity.

Using the movable bridge conveyor you can eliminate the strapping process to secure spacer and bearers below products such as insulation materials, plasterboards and similar.

With RoRo StretchPack®, you can eliminate the strapping process to secure spacer and bearers below products such as insulation materials, plasterboards and similar.

Video: Sealed packaging of geosynthetic roll

Test packaging of large geosynthetic roll during factory acceptance test (FAT) of RoRo StretchPack® XL-S1 model.

This video highlights the advanced functionality of Tentoma’s RoRo StretchPack® packaging machine, engineered for the automated, large-scale packaging of sizable rolls. In this factory acceptance test (FAT), a large geosynthetic roll is packaged to demonstrate the efficiency, reliability, and durability of this cutting-edge solution.

The machine featured is the RoRo StretchPack® XL-S1 model, equipped with a pusher device and conveyor units. In one fully automated process, it wraps each roll in a tubular stretch hood film that is welded at both ends, creating a 100% sealed package. This watertight and dust-resistant seal effectively protects the product from moisture, dirt, and other environmental contaminants, preserving product quality during storage and transport.

While this RoRo StretchPack® model will be installed as a standalone packaging solution on the customer’s site, it is also designed for easy integration into automated production lines. It can handle rolls of varying sizes without the need for manual intervention, supporting flexible and efficient packaging operations.
