Executive summary
PU air pipe is soft and springy, and letting it run free at the end of the line gives you a tangled length instead of a coil. This PU air pipe coiling machine winds the pipe onto a bobbin, using the bobbin to hold the soft pipe in the coil. We build PU pipe coiling machines with bobbin. Pipe range and bobbin plan are confirmed per project.

Why soft pipe tangles
PU air pipe is flexible, and its spring makes it hard to keep in order once it leaves the line. A loose length of soft pipe tangles on the floor or in the box, and untangling costs time at the very end of production. Winding it onto a bobbin is what keeps the soft pipe ordered. The pipe range and its spring are confirmed per project.
What the machine does
The machine winds PU air pipe onto a bobbin, drawing the pipe from the line and building the coil around the bobbin core. The bobbin carries the wound pipe off the machine as a package. Because the coil is built on the bobbin, the soft pipe stays where it was wound. The covered cycle is confirmed per project.
Winding onto the bobbin
The pipe is wound around the bobbin in layers, with the machine guiding each wrap into place as the bobbin turns. Layer winding is what keeps the coil uniform so the bobbin holds its full length. The wind lay follows the pipe section, confirmed per project.
Holding the soft pipe
The bobbin is what holds the package: the wound pipe sits on the bobbin core instead of free-standing, so soft springy pipe keeps its shape. With the bobbin under it, the coil does not sag or spring loose. The finished coil rides on the bobbin until it is used. The bobbin and its size follow the pipe, confirmed per project.
The wound package
What the operator leaves with is a wound package: pipe on the bobbin, ordered and ready to move. A wound package makes the soft pipe easy to handle, store and feed at the point of use. The machine produces the package in one flow from the line. The package standard is confirmed per project.
At the air pipe line
The machine sits where PU air pipe is produced, taking the pipe as it runs and winding it before it can tangle. Running at the line means the pipe is controlled from the moment it is made. The coil is finished before the soft pipe leaves the floor. The line layout is confirmed per project.

What the video shows
Our footage shows a PU air pipe coiling machine winding pipe onto a bobbin. It is a general demonstration, so your pipe range and bobbin plan are confirmed with us per project.
Selection checklist
| Question | Confirm per project |

| Electrical supply | voltage, phase and frequency on site |
Operation and safety
Run the cycle from the panel and the machine winds the pipe onto the bobbin automatically. Keep clear of the winding head, pipe feed, bobbin and outfeed while the machine runs, with guarding and emergency stops at the operator position. Routine checks cover the winding drive, guides, bobbin clamp, sensors and control, per the machine manual. Confirm the wind settings against the pipe before each run so coils stay ordered.
Engineering FAQ
Q: What does this machine wind? A: It winds PU air pipe onto a bobbin, drawing the pipe from the line.
Q: Why a bobbin? A: The bobbin core holds soft springy pipe where a free coil would tangle or sag.
Q: How is the coil built? A: The pipe is wound in guided layers around the bobbin as it turns.
Q: What comes off the machine? A: A wound package, pipe on the bobbin, ordered and ready to move.
Q: Where does it run? A: At the PU air pipe line, winding the pipe before it can tangle.
