Abstract
An apparatus for opening and cleaning fiber material has a casing, a beater cylinder supported in the casing in a horizontal orientation; a grid situated underneath the cylinder; a fiber inlet opening and fiber outlet opening oriented for guiding a fiber carrying air stream parallel to the cylinder axis into, through and out of the apparatus; and a deflector plate situated within the casing above the cylinder. The casing defines above the cylinder a free space which has a height dimension being approximately at least twice the diameter of the cylinder. There is further provided an air outlet opening in an upper part of the casing above the cylinder.
Claims10
In an apparatus for opening and cleaning fiber material, including a casing, a beater cylinder having a longitudinal axis and being supported in said casing in a horizontal orientation;
- a grid situated underneath said cylinder;
- means defining a fiber inlet opening and a fiber outlet opening oriented for guiding a fiber carrying air stream parallel to said axis into, through and out of the apparatus;
- and a deflector plate situated within the casing above said cylinder;
- the improvement wherein said casing defines a free space above said cylinder, said free space having a height dimension being approximately at least twice the diameter of said cylinder and further comprising means defining an air outlet opening in an upper part of said casing above said cylinder and suction means in communication with said air outlet opening for withdrawing one part of the air from the fiber carrying air stream through said air outlet opening.
In a method of opening and cleaning fiber material in an apparatus having a fiber inlet opening and a fiber outlet opening;
- including the steps of passing a fiber carrying air stream through a working zone of a rotating beater cylinder in a direction parallel to the longitudinal rotary axis thereof;
- separating waste from the fiber material by said cylinder and ejecting waste through a grid extending below the cylinder;
- the improvement comprising the step of removing a partial air stream, free from fiber material, through an air outlet opening provided in the apparatus above the cylinder and the fiber outlet opening at a distance which is at least twice the diameter of said cylinder.
