The solutions that remove caps from returnable bottles contribute to the circular economy. A concrete example of circular economy, from “de-cap” to reuse thanks to the reverse capping.
The unscrewing of caps with the inspection system

In this scenario, AROL REVERSE has evolved into a must-have for all bottlers looking for an efficient way to undo pre-threaded plastic caps and threaded aluminum caps off glass and ref-pet bottles.
REVERSE, with 3 to 30 heads, enables safe unscrewing of caps with diameters of 28-38 mm at up to 60.000 caps/h (1.000 caps/min).
The decapping heads of the machine are fully constructed of stainless steel, and other handling components, such as discharge pipes and containers, can also be provided in stainless steel to avoid damaging bottles and extend component life.
Because of its “no decapping” feature, REVERSE can detect bottles without caps without causing bottle neck damage.
The machines are equipped with advanced inspection systems for height variance at the infeed and cap detection at the discharge.
The de-crowning model REVERSE C
REVERSE has been developed for rapid format changes and may be implemented in any plant.
AROL has introduced the REVERSE C de-crowning model: a tough and technically advanced machine for unscrewing crown caps.

Line waste, surplus production, but first deposit return systems: there are numerous instances where a de-capper renders a PET or glass bottle reusable and prevents it from becoming waste.
AROL’s leadership in closure systems (25,000 machines installed worldwide) has led to specialization in de-capping systems (over 200 machines built to date) and, more recently, de-crowning.
The reverse capping. The REVERSE C main features:
- Speed production: up to 12.000 Bph;
- Caps application: to uncork crown caps from glass bottles;
- Inox external surface (IES);
- Quick format change.
The uncorking machine consists of a wheel that turns with grippers that remove the corks out of the bottles and deposit them in a pipe. If the cork wasn’t there, these grippers wouldn’t cause damage to the bottle neck. A blower pushes removed corks as they are released in the pipe.
