ABSTRACT:
A carding machine for forming a fibrous web from textile fibers comprises at least three carding cylinders arranged in succession with worker means for working fibers progressively from cylinder to cylinder, means for rotating the cylinders at successively increasing peripheral speeds in the direction of travel of the fibers, a doffer in working relationship with the last cylinder for receiving the fibers, a means for rotating the doffer at a peripheral speed less than the peripheral speed of the last carding cylinder, the last carding cylinder being rotatable at such a peripheral speed that fibers are projected from the last carding cylinder to the doffer and the doffer being placed sufficiently close to the penultimate carding cylinder without being in working relationship thereto that air flow between the penultimate carding cylinder and the doffer is restricted so that in operation a stream of air flowing with the fibers from the last carding cylinder towards the doffer meets with resistance.
