Samenvatting This 55 s clip from our factory floor shows our steel tube bundle strapping machine banding a bundle of rectangular steel tube. A yellow strapping head on a vertical carriage comes down to the bundle, a blue steel strap is run round it, and the joint is closed with a crimped steel seal. The machine is fixed and the bundle moves through it, so each band lands at its own position along the bundle. Below we set out the cycle, our published strap and seal data, and a worked example for band count and strap use.

Wat de video laat zien
De video is in portretformaat gefilmd en duurt ongeveer 55 seconden.
| Tijd | Wat je ziet |
|---|---|
| Start | A square bundle of rectangular steel tube sits on a blue roller bed under the yellow strapping head |
| Vroeg | The head travels down its vertical guides until it sits on the bundle |
| Midden | Close views of the head at the side of the bundle as the strap is tensioned and sealed |
| Midden | The bundle moves on along the rollers and the next band is set further along |
| Einde | Close-ups of a finished band: blue steel strap across the tube faces, closed by a crimped steel seal |
The footage is ours. Tension and cycle time are not on screen, so the figures below come from our machine data page.
Why a seal joint on tube bundles
- Heavy, rigid loads. A tube bundle is lifted by crane and stacked, so the band has to hold its tension through handling. A crimped seal locks the two strap ends together.
- Square bundle faces. Rectangular tube packs flat, and the band pulls the outer tubes tight against the inner ones, so the bundle keeps its shape.
- Painted or coated strap. The seal grips mechanically, so it does not depend on the strap surface.
- Fixed head, moving bundle. Because the head stays in one place, the band spacing is set by how far the bundle moves between cycles.
Strap, seal and head data
Our published data for the automatic steel strapping head:
| Item | Gepubliceerde waarde |
|---|---|
| Koordmateriaal | Koudgewalst koolstofarm staal, geblauwd en gewaxt |
| Band dikte | 0.8 mm of 1.0 mm |
| Breedte afdichting | 25 mm of 32 mm |
| Gezamenlijk | Dubbele afdichtingsinkeping |
| Seal magazine | Ongeveer 180 zeehonden |
| Bandspanning | 7,000–18,000 N |
| Voeden en opnemen | 2–3 m/s |
| Spanningssnelheid | 6 m/min |
| Hydraulische druk | 100 bar (werkdruk 80-90 bar) |
| Bandjes per bundel | 5 to 7, positioned by bundle length |
Every line is built to order, so the arch, roller bed and band positions follow your tube sizes and bundle length.
Band count and strap use
Band length depends on the bundle section. One band needs about 2 × (W + H) of strap, plus the seal overlap.
Uitgewerkt voorbeeld (ter illustratie). A bundle 400 mm wide and 400 mm high has a perimeter of 2 × (400 + 400) = 1,600 mm, so each band needs 1,600 mm of strap before the seal overlap. With 6 bands the bundle uses about 9.6 m of strap plus overlaps, and 6 seals. With a 180-seal magazine, that is about 30 bundles before the magazine is refilled.
Selectie checklist
- Tube shape (round, square, rectangular) and size range.
- Bundle section, length and weight.
- Aantal banden per bundel en hun posities.
- Strap width (25 mm or 32 mm seal) and thickness.
- Bundels per uur.
- Upstream bundle forming and downstream stacking, such as a steel tube bundle strapping line with a travelling head.
Veiligheid
The head travels down onto the bundle and the strap is tensioned up to 18,000 N. We guard the head and roller zone to the risk assessment, so nobody reaches into the strap path while the machine runs. Hydraulic work is done with the system stopped and pressure released.
Voor de CE-markten passen we ISO 12100 toe voor de risicobeoordeling en EN 415-10 voor de algemene eisen aan verpakkingsmachines.
Veelgestelde vragen over techniek
Q: How is the strap joint closed? A: With a steel seal crimped by a double seal notch, fed from a magazine of about 180 seals.
Q: Which seal widths do you supply? A: 25 mm or 32 mm, to match the strap width.
V: Hoe strak zit de band? A: De bandspanning is instelbaar tussen 7,000 en 18,000 N.
Q: How many bands go on one bundle? A: Our data gives 5 to 7 bands, positioned by bundle length.
Q: How much strap does one band use? A: About 2 × (W + H) plus the seal overlap; a 400 × 400 mm bundle uses about 1,600 mm per band.
Q: Does the head move along the bundle? A: No. The head is fixed and the bundle moves on the roller bed between bands, so band spacing is set by the bundle travel.
Q: How often is the seal magazine refilled? A: A 180-seal magazine covers about 30 bundles at 6 bands per bundle.
V: Hoe snel verloopt het aanvoeren en spannen van de band? A: Het aanvoeren en oprollen gaat met een snelheid van 2-3 m/s, en het spannen met 6 m/min.
V: Welke hydraulische druk gebruikt de kop? A: Het systeem heeft een nominale druk van 100 bar, met een werkdruk van 80-90 bar.
V: Welke normen zijn van toepassing? A: Voor CE-markten zijn dat ISO 12100 en EN 415-10.
