Resumen ejecutivo

A hose coil has to meet three numbers on the order: length, inside diameter and outside size. Our automatic hose coil making machine winds the hose on a drum between flanges, counts the length, cuts it and releases the finished coil, so each coil carries the right metres and fits the same carton or pallet pattern.

A white corrugated hose builds up turn by turn on the winding drum. The finished coil is then wrapped in clear film and handled off the machine as one closed package.

What sets coil size

Diámetro del tambor sets the coil ID.
Flange spacing sets the coil width.
Contador de longitud sets the metres per coil, and with it the coil OD.
Recorrer lays each turn beside the last so the layers stay even.

Change the drum and the flange spacing, and the same machine makes a different coil size.

Coil making sequence

The hose end is clamped on the drum.
The drum turns and the traverse lays the hose between the flanges.
The counter stops the drum at the set length.
The hose is cut.
The coil is strapped or wrapped while still held on the drum.
The drum releases and the coil is taken off.

Coil length from coil size

Turns per layer ≈ coil width ÷ hose OD

Layers ≈ (coil OD − coil ID) ÷ (2 × hose OD)

Length ≈ π × (OD + ID) ÷ 2 × turns per layer × layers

Example only: 20 mm hose on a coil of ID 350 mm, OD 500 mm and width 200 mm gives 200 ÷ 20 = 10 turns per layer and 150 ÷ 40 = 3.75 layers. The mean turn is π × 425 ≈ 1,335 mm, so the coil holds about 1,335 × 10 × 3.75 ≈ 50,000 mm, or 50 m. Run the other way, this tells you the OD a 50 m coil will reach. The formula assumes turns sit square on each other; corrugated hose nests a little into the layer below, so a trial coil is wound to set the counter.

Releasing the coil

The finished coil grips the drum, so the drum must let go before the coil can come off. Collapsing drum segments or a stripping plate push the coil clear without pulling turns out of shape. Strapping or wrapping before release is what keeps the coil round once it leaves the drum.

Seguridad

We design to EN ISO 12100:2010 for risk assessment, EN 415-10 for packaging machine safety and EN 60204-1 for the electrical equipment. The drum is guarded and the cutter works only with the guard closed.

Preguntas frecuentes sobre ingeniería

Q: How do I get a smaller coil OD for the same length? A: Use a wider coil or a smaller ID, within the machine range.

Q: How fast does it coil? A: 1–60 m/min.

Q: Can it make coils for cartons? A: Yes; the coil size is set to the carton.

Q: Does it work behind the extruder? A: Yes, with two stations so winding does not stop.
