ABSTRACT:
The fiber opening machine has an opening drum with adjacent trough, which receives fibers from a feeding device with feeding rollers. The fiber opening machine has a suction chamber for generating an air current to remove open fibers from the opening drum. The suction chamber is defined by the output side of the opening drum and an opposing suction chamber wall which is shaped to form a biconcave space through which a current of air is passed to remove the fibers from the opening drum so that fibers are removed from the drum without nep formation at rotational speeds which are higher than those attainable without the biconcave space.
