ملخص تنفيذي
A wooden timber strapping and wrapping line ties a pack of sawn timber, boards or panels with straps and covers it in film, so it travels as one solid, dry unit. Straps hold the pieces; the film keeps off rain, dust and sunlight; bearers underneath let a forklift lift the pack. Our timber lines combine strapping, automatic bearer feeding, corner protectors and either a film cover or a horizontal stretch wrapper. Below: the packing methods, how the line works, a worked example and what to send us.

Why strap and wrap timber packs
Sawn timber, floor boards and panels leave the mill as loose stacks. Without straps the pieces slide when the pack is lifted; without cover, rain stains the faces, sun greys the surface and dust settles in grooves. Packed timber also needs bearers underneath, so forks can enter, and protection on the corners where straps bite.
Strapping alone holds the pack. Wrapping alone protects it. Most export timber needs both.
Three ways to wrap timber
| الأسلوب | كيف يعمل | أفضل ل |
|---|---|---|
| Film cover (hood) | film is drawn over the top and sides of the stack and sealed | packs stored outside; top and sides need protection |
| Horizontal stretch wrapping | a ring spirals film round the pack as it passes through | long packs, all four long sides covered |
| Strapping only, with corner guards | straps at set spacing, card corners under them | short-haul, covered transport |
The film cover suits stacks of boards and panels. Film is drawn from the reel over the stack as it moves along, then the upper sealing unit comes down to seal and cut, and the covered stack leaves on the conveyor.
How a timber packing line works
- التغذية. The stacked pack arrives on roller conveyors.
- Bearers. An automatic timber feeder places bearers under the pack bottom.
- زوايا. Cardboard corner protectors are placed at the top corners.
- حزام. The strapping unit ties the pack, with bearers and corners, at each strap position.
- التفاف. The pack is covered with film, or passes through a horizontal stretch wrapper.
- إخراج. Finished packs leave for labelling and storage.
On a horizontal wrapper, timber blocks and spacers can be fed top and bottom of the bundle automatically before the film goes on.
Worked example: straps and film
Illustrative pack: 3,000 mm long, 1,000 mm wide, 600 mm high, strapped at 1,200 mm pitch with the end straps 300 mm in from each end.
| تحقق | عملية حسابية | نتيجة |
|---|---|---|
| وضعيات الحزام | 300 و 1,500 و 2,700 ملم | أحزمة 3 |
| Bearers | one under each strap | 3 |
| Film, top and sides | 3.0 × (1.0 + 2 × 0.6) | 6.6 متر مربع |
| Film, both ends | 2 × 1.0 × 0.6 | 1.2 متر مربع |
| Film, full cover | 6.6 + 1.2 | 7.8 متر مربع |
نتيجة. Three straps over three bearers, and about 6.6 m² of film for a top-and-sides cover or 7.8 m² closed at the ends, before overlaps and seals.
Horizontal wrapper data
For lighter bundles wrapped all round, our E1000 horizontal stretch wrapper takes:
| العناصر | E1000 |
|---|---|
| طول العبوة | أكثر من 1,000 ملم |
| Pack size (across) | 400 – 1,000 مم |
| وزن العبوة | 50-400 كجم |
| التفاف | LLDPE film, paper or woven, 100–500 mm wide |
| الناقل | 3-12 م / دقيقة |
| حلقة | 10–60 دورة/دقيقة |
| الطاقة | 4.5 كيلو واط |
The E1000 is for light bundles up to 400 kg, such as flooring and mouldings. A full sawn-timber pack like the one in the example weighs well over that, so it gets heavy-duty conveyors and a wrapper built to the pack weight.
Best practices for timber
- Strap over bearers so the strap tension clamps them in place.
- Use corner protectors where straps cross edges.
- Cover the top at least, for any pack stored outside.
- For green timber, choose a cover that lets moisture escape, or leave ends open.
- Label after wrapping, on the film, so the label stays dry.

السلامة: EN 415-10 و ISO 12100
Wrapping and strapping lines are built to EN 415-10, with the risk assessment done to ISO 12100. The hazards are the descending sealing unit, the strapping head, the turning ring on a wrapper and heavy packs on conveyors. We set guarding and interlocks in the risk assessment for each layout.
أسئلة وأجوبة هندسية
Q: Can bearers be placed automatically? A: Yes, an automatic timber feeder puts them under the pack bottom.
Q: Film cover or stretch wrap? A: Film cover for top and sides on stacks; stretch wrap to cover long packs all round.
Q: What do you need to quote? A: Pack length, width, height and weight.
Q: Can the line add corner protectors? A: Yes, cardboard corners at the top corners, placed automatically.
