Winders are machines that play a key role in many industries – from the production of films and technical fabrics to the processing of wire or fibers. Their task is to precisely wind material onto cores or rolls, which requires perfect alignment of all machine components.

In one of our recent projects, we were involved in correcting the parallelism of the rollers of a winder used in the production of raschel bags – popular packaging for vegetables and fruits.

What did the measurement look like?

The first step was to determine the axes of all the winder rolls and check their alignment with respect to each other and with respect to the base, which in this case was the extruder.
To complete the task, we used a Laser Tracker – a device that allows precise spatial measurement with an accuracy of tenths of a millimeter. The accuracy for a single measurement is about 0.025 mm, which equals 25 micrometers. To make it easier to imagine this value, it is worth mentioning that the human eye is unable to perceive objects smaller than about 0.040 mm.

Thanks to the experience of our operators, it was also possible to make adjustments to the roller setting in real time, which significantly accelerated the entire process and avoided downtime.
After the adjustment, we conducted a final measurement, which confirmed the correctness of the changes made.

All data – both before and after correction – was compiled in the form of an easy-to-read measurement report provided to the client.

Effect for the customer

After the work was completed, the winder was perfectly aligned – the rollers are parallel to each other, which translated:

• A reduction in the amount of production waste,

• Increasing line efficiency,

• Improving the quality of finished products.

Why is this important?

In machines such as winders, even small deviations in roll alignment can lead to uneven winding, stretching of the material or damage to the material.
Regular inspection and correction of component parallelism is an investment that makes a real difference in the stability and efficiency of the entire production process.

Precise machine geometry is a guarantee of smooth operation.
