Abstract
A carding machine is provided with two doffers. At least one of the doffers has an intermediate roller coordinated thereto. The doffer roller and the coordinated intermediate roller are shiftable into two different operating settings. In a first operating setting the intermediate roller is out of operation and the doffer roller works in a usual manner in combination with the main cylinder. In the other setting the doffer roller is out of operational contact with the main cylinder, and the intermediate roller, which has the same direction of rotation as the main cylinder, is positioned so as to transfer the fibers from the main cylinder to the doffer roller. The second doffer roller may have a second intermediate roller coordinated thereto. The fiber fleeces leaving both doffer rollers are combined to form a compound fiber fleece.
