Abstract

The invention relates to a rail (16a) of a flexible drive, which rail (16a) is intended to guide a drawing means (2). A lubricant which is introduced into the rail (16a) via the lubricant channel (13) brings about a pressure gap (15) which is formed between the inner side of the drawing means (2) and a guide face (9) of the rail (16a). Direct contact of the drawing means with the rail (16a) is suppressed on account of the lubricant which is introduced into the pressure gap (15), which has a friction-reducing effect.
