The COT-2 pneumatic tyre doubling/unpacking machine (tyre doubler) is ideal for companies involved in exporting scrap or used tyres. It is used to double or triple tyres (pack them one inside the other up to a maximum of 3 in a bundle), significantly reducing the cost of transporting them. It also has a tyre unpacking (undoubling) function, but it is very limited (unpacking packs of more than 3 tyres requires a tyre unpacker).
It is powered by compressed air. Thanks to its small size and weight, this doubler is easy to move to the required location and does not take up much space itself.
This machine is often used by tyre pyrolysis plants, as packing the tyres into bundles allows more tyres to be inserted into the reactor without having to cut through them. This ensures that the intact steel wire is arranged in bundles, making it significantly easier to separate it from the soot and pyrolysis oil once the reaction is complete.
We are the original inventor of this type of machine and we patented it. Similar machines on the market are cheap knockoffs of this model and they break down quickly while our machines are very durable and they can work for many years even without proper maintenance.
For production, we use only the highest quality components that meet high safety standards. We will also offer technical support for several decades.
