Online Tire Stack Strapping Machine: One Vertical Band per Stack on a Roller Conveyor

Executive summary This online tire strapping machine works directly on a powered roller conveyor. A stack of film-wrapped tires runs into the station, two side guides hold it upright, the head above applies one vertical band, and the strapped stack runs out. Below we set out the strapping cycle, how to size the band, and what to fix before the strapper is linked to a tire wrapping line.

What the machine does

The station unitizes tire stacks inline, without lifting them off the conveyor bed:

Cycle phase Machine action
Infeed The driven roller bed stops the stack beneath the strapping head
Hold Two vertical side guides close on the stack flanks, keeping the column upright
Band The head feeds one band round the stack in the vertical plane, through the tire eye
Tension and seal The band is tensioned, sealed and cut from the coil
Outfeed The guides retract and the rollers carry the strapped stack out

Each tire is film-wrapped before it reaches the strapper. The stack stays upright from infeed to outfeed and is not turned. The strapping head sits in a housing above the conveyor, on a steel frame around the stack.

The strapping cycle, step by step

  1. Infeed. The powered rollers bring the stack into the station and stop it under the head.
  2. Hold. The side guides close on the stack so it stands straight while the band goes round.
  3. Band. The head feeds the band round the stack in the vertical plane.
  4. Tension and seal. The head pulls the band tight, seals it and cuts it from the coil.
  5. Outfeed. The guides open and the rollers carry the strapped stack out; the next stack comes in.

Standard recipes apply one vertical band per stack. On flows that ship stacks loose in containers, a second band at 90° can be added by turning the stack between two cycles; we set that per project.

Band length per tire stack

Band length follows the stack height and the tire outer diameter (OD). The values below are an illustrative example, not a rating of the machine:

Item Value
Tire OD (illustrative) 600 mm
Tire width (illustrative) 110 mm
Stack height, 9 × 110 mm 990 mm
One vertical band, 2 × (990 + 600) mm 3,180 mm
Two bands per stack 6,360 mm

Add the seal overlap to each band when you size strap coils. We run the trial with your own tires, so the recipe uses your real stack height.

Where the strapper sits in a tire packing line

Position Why it is placed there
After the tire wrapper Tires arrive film-wrapped and stacked
Before palletizing or storage Strapped stacks handle as one unit on forklifts or conveyors
On the main conveyor, inline The stack is not lifted off the line, so the station runs at line pace

Upstream of this station, our tyre packing machines wrap individual tires at 25–35 sec/pcs with roller speeds of 2–4 m/min on 5–7 bar air [manufacturer rating], so wrapped tires arrive stacked and ready to band. For single-tire wrapping ahead of this station, see our tyre packing machines. Our online tire strapping machine with a press compresses the stack before banding, which suits loose, unwrapped tires.

Selection checklist for an online tire strapping machine

  • Tire OD, width and weight range, and tires per stack.
  • Bands per stack: one vertical band, or two at 90°.
  • Strap material, width and thickness you buy locally, and the band tension your stacks need.
  • Stacks per hour the upstream wrapper delivers.
  • Conveyor height, roller pitch and flow direction.
  • Whether stacks arrive film-wrapped or bare.
  • Destination market for the risk assessment.

Controls and safety

The head, the side guides and the powered rollers all move while a stack is in the station. Keep hands out of the station during the cycle and clear a jam only with the machine stopped and isolated. A warning label is fixed on the strapping head housing.

For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets general requirements for packaging machines, which fixes guarding, the emergency-stop circuit and access to the station.

Engineering FAQ

Q: How many bands does the station apply? A: One vertical band per stack. A second band at 90° needs the stack turned between two cycles.

Q: What sets the cycle time? A: Conveyor transfer speed, stack height and the tensioning stroke. The station is set on trial to clear stacks at the pace of the upstream wrapper.

Q: How do I work out band length? A: Use 2 × (stack height + tire OD) per band plus the seal overlap; 990 mm and 600 mm give 3,180 mm in our example.

Q: Does the machine turn the stack for a cross band? A: No. The stack stays square to the line and gets one vertical band; a second band at 90° needs the stack turned between two cycles.

Q: Can the same station strap stacks of different heights? A: Yes. The head bands round the full stack in the vertical plane, so one station runs several stack heights; we set the stop position and guide settings per tire size on trial.

Q: Do the tires have to be wrapped first? A: No. Wrapped tires are the usual feed, but loose stacks are usually pressed before banding, as in our press-type tire strapper.

Q: Which standards apply? A: For CE markets, ISO 12100 and EN 415-10.

Next step

We plan a tire strapping station in three steps:

  1. Submit your layout drawing with tire sizes, tires per stack and stacks per hour, to info@fhopepack.com.
  2. Receive a proposal within 48 hours, with band pattern, conveyor height and the station layout.
  3. Book a site survey so we confirm the link to your wrapper and the guarding.
