Packaging lines
Tube bundles
A packaging line for tube bundles is a set of stations that automates the end of line: from the arrival of the material to the departure of the bundle formed, strapped and ready for shipment.
We designed it to ensure stable and repeatable strapping, reduce manual handling and fit in with your productivity and layout.
SAIZAR configurations for tube bundles
At SAIZAR, we offer specific product lines for tube and pipe bundles, with two evacuation options depending on your plant’s flow: front exit or side exit.
Front outlet
Ideal when the line continues on the same direction (accumulation, labelling, dispatch) and you look for a straight flow. In these cases the bundle remains at the strapping station, while the strapping machine moves to each strapping position.
Side outlet
Recommended when you need to divert the bundle to a another conveyor, to a storage area or to an alternative exit without interfering with the entrance. In these cases, the bundle moves to each strapping position, while the strapping machine remains in a fixed position during the strapping process.
Standard modules in a tube packaging line
Transport, centering and bundle alignment
We define how the bundle enters and how it is positioned before the strapping:
- If the bundle arrives centered (keeping the same center even if the width changes).
- Or if it arrives aligned to one side (referenced to a side).
And we configure the transport according to your plant: conveyor, rollers, chains, elevator, crane or others.
Bundle forming and compacting
If your process requires it, we incorporate a forming and/or compacting system to stabilize the bundle before the strapping. These units are common in automatic line projects and we size them according to product, cadence, and space.
Automatic transverse strapping
For tube bundles, we propose automatic strapping with various strategies:
- Transversal strapping by positions: the strapping machines can be fixed and the bundle can moves to each position, or the strapping machine can move sideways while the bundle is held in place.
- Steel strap and/or polyester strap (PET) in industrial widths of 16 / 19 / 25 / 32 mm, depending on the application.
- The strapping head can incorporate vertical movements to perform strapping on the top of the bundle, and we work with round, square/rectangular and hexagonal bundles.
- If you also need to strap the bundle at the same time using several automatic strapping machines, we can design the equipment for this function.
Sealing according strap (Technical selection)
- For steel: notching, with linker (seal), or TIG welding (depending on requirements). The most common method for this type of strapping product is with linker, as it can be better adapted to the smallest flat part of the bundle.
- For PET: friction–vibration.
Introduction of elements: cardboard, labels and wooden blocks
To protect the product and improve the presentation/shipping, we can incorporate the automatic insertion of:
- Metal or plastic plates with or without labels,
- Cardboard,
- Wooden blocks.
In the case of the wooden blocks, the system can operate with automatic feeding through specifically adapted storage units (with capacities up to 100units, depending on requirements) and a pusher to place them in the desired position according the size of the product and its positioning in relation to the conveyor.
Conveyors & strapping tables
When the bundle needs to be strapped in different positions, we include conveyors and strapping tables, with controlled stops by drive and encoder, sized according to weight, measurements and available space.
Weighing and labeling for traceability
If you require traceability, we can include in the line:
- Weighing system.
- Labeling system.
Strapping and packaging systems by SAIZAR
In-plant benefits
Stable and repeated strapping:
with positioning strategies(mobile packaging or machine) and parameters adapted to your product
Genuine flexibility:
for tubes/pipes with round, squared, rectangular and hexagonal bundles
Less incidents:
due to a correctly defined alignment (centered or lateral) from the start
Protection and improved dispatch:
automatically integrating cardboard, wooden plates or blocks
Traceability:
with weighing and labelling integrated into the line itself
Improve the productivity:
enabling the production of more tubes and the formation of more bundles than with a manual application
Increase safety:
reducing manual handling by the operator

Checklist for sizing your tube&pipe line
In order to propose the Right architecture, we usually need:
Product to be strapped, weight and maximum temperature of the bundle
Minimum/maximum dimensions of the bundle: width (A), height (B), length (C) and if it is applicable, diameter (D) and flat part (A1)
Alignment of arrival: centered or aligned to one side (which one)
Target productivity (bundle /hour)
How the material is moved/evacuated: trolley, rollers, chains, lift, crane or other means
Type of strap (steel or PET), width/thickness and type of sealing required
Minimum/maximum number of strapping per bundle
If you want to add modules: forming, compacting, weighing, labeling, introduction of wooden blocks, etc
Technical service and spare parts
In addition to design and integration, we support you with maintenance to ensure availability: commissioning, process adjustments, maintenance and spare parts throughout the line’s life cycle.
Frequently asked questions
What is the difference between a front outlet and a side outlet?
The front outlet maintains straight flow; the side outlet diverts the bundle to better fit your layout or alternative evacuation. The front outlet requires less space but reduces productivity, while the side outlet increases productivity and requires more space for integration.
Should the strapping machine be fixed or can it be moved?
We can design the fixed strapping machine with the bundle moving to the different strapping positions, or with lateral movement of the strapping machine while the bundle is stationary.
What type of straps can we use for tube bundles?
We can strap with steel and/or PET and in widths of 16/19/25/32 mm depending on the application.
What types of bundles can we strap?
We work with round, square/rectangular and hexagonal bundles, sizing the system to your format.
What type of sealing do we use on steel and PET?
For steel: notching, with linker or TIG welding (depending on requirements), with linkers being the most common sealing system. For PET: friction-vibration.
Can we use different sizes and types of strapping on the same line?
Yes, if you need it, we can offer equipment capable of using two different types of straps in different sizes, without the need to adapt two separate strapping stations for this purpose.
Can we automatically insert cardboard, small wooden plates or blocks?
Yes. we can integrate plates, cardboard or wooden blocks according to your packaging standards.
What information do you require to provide a quote?
Weight, temperature, minimum/maximum measurements, productivity, arrival alignment, transport/evacuation, type of strapping, sealing, number of strapping and available space.
Can weighing and labelling be integrated into the line?
Yes, we can add both modules within the automatic line.
How do we define the best architecture for my plant?
With your layout and product data, we define the flow (input, forming, strapping, output) and whether front or side output is best, mobile bundle or mobile strapping machine, and which modules provide the best return.
