IPC: B21C47/02
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent winding deviation of a winding coil by generating high- speed flow of air in the direction perpendicular to the traveling direction of a metallic thin strip in the winding inner inlet region when the metallic thin strip is wound on the coil at high speed. SOLUTION: When a metallic thin strip 2 is wound on a coil 1 at high speed, a blow-off nozzle 6 for high-pressure air is attached on the driving side of the coil 1, and high-speed air is blown in the direction D perpendicular to the traveling direction A of the metallic thin strip 2 in the winding inner inlet region 5. The blowing direction of air from the nozzle 6 is the direction C. At this time, it is desirable that the blow-off speed of air is high, and the speed equal to or not less than the traveling speed of the metallic thin strip 2 is required. If the traveling speed of the metallic thin strip 2 is about 1600m/min., the blow-off speed of air is about 1600m/min. or more. Therefore, the restricting force of the coil 1 to the metallic thin strip 2 is increased by decreasing film thickness of winding air, and winding deviation of the coil 1 can be prevented.
