Thin metal strip winding method and thin metal strip winding system

Abstract

A thin metal strip winding method includes: a step of causing a thin metal strip to fly from a flight tube; a thin metal strip connecting step of connecting any portion of the thin metal strip flying from the flight tube and a leader as a ribbon, the leader being a to-be-connected portion of another thin metal strip remaining on a winding roll set on a winding roll rotation unit of a winder that winds up the thin metal strip; and a thin metal strip winding step of winding up the ribbon around the winding roll by causing the winding roll rotation unit to rotate.

What is claimed is: 
     
         1 . A thin metal strip winding method comprising:
 a step of causing a thin metal strip to fly from a flight tube;   a thin metal strip connecting step of connecting any portion of the thin metal strip flying from the flight tube and a leader as a ribbon, the leader being a to-be-connected portion of another thin metal strip remaining on a winding roll set on a winding roll rotation unit of a winder that winds up the thin metal strip; and   a thin metal strip winding step of winding up the ribbon around the winding roll by causing the winding roll rotation unit to rotate.   
     
     
         2 . The thin metal strip winding method according to  claim 1 , wherein
 the winding roll set on the winding roll rotation unit is a winding roll after being used with a small amount of a thin metal strip left thereon.   
     
     
         3 . A thin metal strip winding system comprising:
 a flight tube which causes a thin metal strip to fly;   a winding roll rotation unit on which a winding roll with a thin metal strip remaining thereon is set;   a connecting unit which connects any portion of the thin metal strip flying from the flight tube and a leader as a ribbon, the leader being a to-be-connected portion of the thin metal strip remaining on the winding roll; and   a winding unit which winds up the ribbon around the winding roll by causing the winding roll rotation unit to rotate.   
     
     
         4 . The thin metal strip winding system according to  claim 3 , wherein
 the connecting unit is configured to connect the leader and the ribbon in a state where the leader and the ribbon are disposed vertically.   
     
     
         5 . The thin metal strip winding system according to  claim 3 , wherein
 the connecting unit is configured to connect the leader and the ribbon in a state where the leader and the ribbon are disposed horizontally.
