ABSTRACT:
Carding cylinder takeoff apparatus for producing a randomized web of textile fibers comprises a doffing roll, a wire covered transfer roll closely spaced from the doffing roll surface and a rotatable takeoff roll having a resilient rubber surface with a Shore A Durometer hardness of less than about 80 closely spaced from the transfer roll. The transfer roll is rotated in the same surface direction and at a surface speed less than that of the doffing roll for transferring the fibrous web and forming fiber hooks in the web to randomize it. The takeoff roll is rotated in the opposite surface direction and at a surface speed greater than that of the transfer roll for removing the randomized web from the transfer roll.
