Wiping arrangement for wiping a vehicle window, and a method of manufacturing the same

摘要

A wiping arrangement for wiping a vehicle window has an elongated wiping element turnable about an axis and arranged to contact the vehicle window during such turning so as to wipe the same. The wiping element has a coefficient of friction which differs in the direction of elongation thereof. In accordance with a method of manufacturing the arrangement, a coefficient of friction which differs in the direction of elongation of the wiping element is imparted to the latter. The coefficient of friction of the wiping element may differ from one to another end of the latter in a stepped manner or in a stepless manner. The different coefficient of friction may be imparted to the wiping element by chlorinating of the latter so that different longitudinally spaced portions of the wiping element are exposed for contacting with chlorine during different times.
