DEVICE FOR SEPARATING WASTE FROM FIBER MATERIAL WHILE PROCESSED IN A CARDING MACHINE

摘要

A carding machine includes a main carding cylinder having a cylindrical surface carrying a cylinder clothing; a cover arrangement extending along a part of the cylindrical surface at a clearance therefrom to define a space between the cylinder clothing and the cover arrangement; a first opening provided in the cover arrangement and communicating with the space between the cylinder clothing and the cover arrangement; and a device for generating a pressurized air stream. The device communicates with the first opening for introducing the pressurized air stream through the first opening into the space between the cylinder clothing and the cover arrangement to impinge upon the cylinder clothing carrying fiber material thereon. A second opening which is provided in the cover arrangement communicates with the space between the cylinder clothing and the cover arrangement for removing the pressurized air stream, laden with waste material separated from the fiber material.
