Abstract:
A pressure control system is provided for use with a carding machine having a carding cylinder with clothing. The pressure control system has a cover for positioning opposite the carding cylinder clothing, an opening in the cover for separating foreign particles from desirable fibers, and a replaceable pressure regulator mounted in the cover. The pressure regulator is for adjusting a pressure between the cover and the carding cylinder.
Abstract:
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.
