A carding machine includes a main carding cylinder; a doffer cooperating with the main carding cylinder for removing fiber material therefrom; a stripping roll cooperating with the doffer for removing a fiber web therefrom; upper and lower cooperating crushing rolls together defining a nip for grasping the fiber web running from the doffer and the stripping roll; and a fiber web supporting and guiding body stationarily positioned underneath the stripping roll. The body has a length dimension extending generally parallel to the rotary axis of the stripping roll and an upper surface for supporting and guiding thereon the fiber web. The upper surface has a width extending generally horizontally and transversely to the stripping roll axis and oppositely located first and second longitudinally extending edge zones. The first edge zone is situated in a region between the doffer and the stripping roll and the second edge zone is situated in a region between the stripping roll and the crushing rolls and is oriented towards the nip defined by the crushing rolls.
