圆捆打捆机（10）设有打捆室（28），并用于将打捆完成的捆包打包在打捆室（28）的可接合限制装置中。 打包室（28）的轴向尺寸可以通过至少一个侧壁（26）改变，该侧壁可以通过调节驱动装置（32）进行调节。 调节驱动器（32）构造成使得在打捆期间打捆室（28）的轴向尺寸与捆包首次增加时提供的尺寸相反，然后再次减小以用于制动捆包。

A round baler (10) is provided with a baling chamber (28) and verbringbaren for ejecting a completed bale in an opening position limiting means of the baling chamber (28). The axial dimension of the baling chamber (28) is variable by at least one means of a Verstelltriebs (32) adjustable side walls (26). The adjusting drive (32) is configured such that the axial dimension of the baling chamber (28) during ejection of the bale with respect to the intended when creating the bale size increases initially and then decreased again to the deceleration of the bale.
