See what is worth knowing about proper winding.
Core, spool, roll – what is worth knowing?
Before we explain how important it is to wind materials properly, it is worth becoming familiar with the basic terms used in this field. When discussing winding and unwinding, we most often hear about cores. These are paper or cardboard tubes onto which a selected material is wound. We can find them in every home. A core is simply the cardboard roll left at the end of toilet paper, paper towels or aluminium foil. Another term is spool. We also often encounter these. Thread, fishing line and wire are most commonly wound onto spools. The final term is roll. A roll means the whole item, that is, a core wrapped with the selected material. We can therefore speak of a roll of toilet paper or a roll of cling film.
Even Winding – That Is the Biggest Secret
We can sometimes see what happens when paper towels are wound unevenly or too loosely when we buy defective rolls. The towels are creased when unwound and are often even torn. That is why it is very important for the machines winding paper onto a core to be set with great precision. Web guiding is used for this purpose (more on this subject: https://www.ibd-wt.de/pl/uslugi-i-produkty/regulacja-tasmy.html). Thanks to specialist ultrasonic sensors and devices monitoring the web of paper, material or foil being wound onto the core, there is a high probability that the roll we bring home will be smooth and precisely wound.
It may seem that it is not particularly important whether a roll of paper towels is perfectly wound or not. However, it is worth remembering that paper used to make books and magazines, the material used for our clothes, and wound dressings are wound in the same way. In the case of these products, improper winding onto a core may result in the need to destroy the entire batch of wound material.
