The breaker card, fed, via the conveyor, by the loader, is made up of two drums connected by a conveyor cylinder.
The first drum, equipped with a feeder group and a series of working-stripping cylinder pairs, makes up the pre-carding unit, and is entirely wired. It opens further the material originating from the preparation stage, eliminating impurities and the largest neps, and thereby also protecting the flexible clothings on the subsequent processing cylinders against excessive wear and damage.

The peripheral speed of this first drum is around 300 m/min, that is around half that of the subsequent drums, because initially the fibres need to be processed more gently in order to avoid breakages or the uncontrolled formation of tangles.
Thanks to the action of a conveyor cylinder, the material passes from the pre-carding unit to the second drum, which is clothed with needles, and to the pairs of worker-stripper cylinders, the fly cylinder and the comber roller. The comber roller is unloaded by the doffer comb and the web is fed to the crossing card on a conveyor belt.
