A bale is formed and wrapped in a bale forming chamber into a web of wrapping material. The web is conveyed towards a wrapping material inlet (92) and is injected through this inlet (92) into the bale forming chamber. A web conveying device (1 00) being in a conveying position and a bale forming means together convey the web towards the wrapping material inlet (92). In addition a web processing member (251) being in a working position processes the web. A coupling member (53.1, 53.2, 56) transfers a movement of the web processing member (251) from a parking position into the working position onto the web conveying device (1 00) such that the web conveying device (1 00) is transferred from a parking position into the conveying position.
