Abstract
A ventilated carding cylinder for allowing heat generated in the carding cylinder during operation to be dissipated. The carding cylinder includes an internal, longitudinally extending, air flow passage and impeller means provided therein for moving air through the air flow passage during operation of the carding cylinder. This movement of air aids in dissipating heat generated by the carding cylinder during the fiber carding process. Reduction of heat in the carding cylinder can minimize the risk of fire occurring in the fibers and also thermal growth of the cylinder during operation.
Claims14
A fiber carding roll for use in a textile processing machine, the fiber carding roll comprising:
- a cylindrical member having a circumferentially extending fiber carding surface and a first end and a second end opposite said first end said first and second ends having openings;
- said cylindrical member defining an internal air flow passage extending the length of said cylindrical member for allowing air to pass therethrough;
- and
- at least one impeller provided in said air flow passage for propelling air from said first end to said second end of said cylindrical member.
A carding cylinder for use in a textile processing machine, the carding cylinder having a circumferentially extending fiber carding surface and defining an internal air flow passage extending substantially the length of said cylinder for allowing air to pass therethrough and a plurality of heat sinks connected to the carding cylinder within said air flow passage and extending a major portion of the length of said air flow passage for dissipating heat generated during operation of the carding cylinder in the textile processing machine.
A fiber carding roll for use in a textile processing machine, the fiber carding roll comprising:
- a cylindrical member having a circumferentially extending fiber carding surface and a first end and a second end opposite said first end said first and second end having openings;
- said cylindrical member defining an internal air flow passage extending the length of said cylindrical member for allowing air to pass therethrough;
- and
- a blower for propelling air from said first end to said second end of said cylindrical member.
