Shrnutí A timber bundle has to survive the truck before it earns the mill’s profit. An orbital wrapping line wraps the bundle in stretch film and then straps it with PET or steel banding, so film keeps moisture and dirt off the face while the strap carries the structural load. Bundle length, film program and strap type are configured per project.

Two jobs: film and strap

Film and strap do different work on a timber bundle. The film layer seals the faces, keeps moisture and dirt away from the wood, and holds the surface together. The strap carries the real clamping load, holding the stack square so it does not loosen on the truck.

Running both on one line means the bundle is wrapped and strapped in a single pass instead of being moved twice.

Jak linka jezdí

The bundle moves on a conveyor through a rotating film ring that wraps the full length in an overlapping spiral. Downstream, a strapping unit applies one or more tensioned bands across the bundle, tensions them to a preset limit and then joins the strap ends. Strap count and spacing are selected per project from bundle length and transport dynamics. Film first, strap second, at consistent tension every cycle.

Film layer: what it carries

Film width and pre-stretch are set to the bundle; pre-stretch elongates the film before application so each roll covers more timber.
Overlap between spiral turns is set by ring speed against conveyor speed.
End wraps lock the bundle ends so no profile edge catches on hooks or forks.

Strap: PET or steel

Popruh	Nejlepší pro
PET pásek	regular bundles where a tough, slightly elastic strap suits handling
Steel banding	heavy, long-haul loads that need the highest tensile rating

Strap tension is preset so it holds the stack without crushing the bundle edges. The joint is made by friction welding for PET or with metal seals for steel banding.

Příprava svazku

Square the bundle before it enters the line. Even ends wrap cleaner and strap more squarely, which matters because a strap that sits at an angle does half its share of the holding work. Keep the stack neat at the edges and the film thickness and strap spacing can stay consistent across the shift.

Sekvence stroje

Bundle arrives on the infeed conveyor and squares to the centerline.
Orbital ring wraps the full length in film with end reinforcement.
Bundle indexes to the strapping station.
Strapping head tensions the band to the preset value and joins the ends.
Finished bundle leaves at the outfeed for racking or loading.

Ovládací prvky a bezpečnost

The panel stores a program per bundle type, with ring speed, conveyor speed, overlap and strap tension preset. Keep clear of the ring and the strapping head while they run, and keep guarding closed during operation. An emergency stop is fitted at the panel. Film threading and strap threading follow the machine manual.

Často kladené otázky k inženýrství

Q: Do I need both film and strap? A: Film seals and stabilizes the faces; the strap carries the clamping load. Heavy, long-haul bundles normally run both.

Q: PET or steel strap? A: PET suits regular duties; steel banding is chosen for the heaviest loads. Strap type, width and joint are confirmed per project.

Q: Can it handle green or wet timber? A: Film keeps moisture off the faces and stain from spreading; the machine itself handles the weight the conveyor and ring are rated for, confirmed per project.

Q: What strap tension is applied? A: Tension is preset per bundle type so the stack is held without crushing the edges; it is confirmed with you at start-up.

Q: How fast does the line run? A: Cycle time depends on bundle length, film pattern and strap count. We size the line to your outfeed rate per project.
