Abstract
Air channels (11) are provided in a needle strip for the removal of contaminants that are deposited in the open passageways (F) between the needle points (4), which air channels can be connected to a compressed air source or a vacuum source via an air chamber (15). With die-cut and swaged needles (1), the air channels (11) are preferably formed by an extension of the swaging (10) into the region between the cover plates (2,3). Pursuant to the cleaning process, compressed air, preferably pulsed, is directed at the point region for cleaning purposes.
