A device for stripping a fibrous web from a doffer in a carding machine comprising a doffing roller for directly stripping the web from the doffer, a guide roller for guiding the web and a punched suction roller provided adjacent to the guide roller for feeding the web to a collector in combination with the guide roller. All the rollers are placed in mutually adjacent, parallel relation and are positively rotated. Within the punched roller, there is provided a stationary duct which is connected to a source of negative pressure. The duct includes an elongate suction port having a length corresponding to the effective length of the punched roller. The suction port faces the space between the punched roller and the guide roller. Air is drawn into the duct through a multiplicity of holes in the punched roller to prevent winding of the web around the doffing roller and the guide roller and remove waste fibers and impurities from the web.
