摘要

The apparatus has a cleaning-checkmark foil (1) formed on a working face for receiving foreign bodies, where trimming of the cleaning checkmark foil with a checkmark is turned off on comb-out of the foreign bodies from the cleaning-checkmark foil by a comb. Density of the trimming with checkmarks is reduced by the checkmark foil, where density of the checkmarks is set between 100-500 amounts. The comb is made of metal and arranged on the checkmark foil. Pole threads (3) are formed on the checkmark foil.
