Manufacturing method and manufacturing device of tire belt

A manufacturing method of a tire belt for manufacturing a sheet-like belt first from a master roll formed by covering multiple belt cords lined up parallel to one another with rubber, and then forming a cylindrical belt by winding the sheet-like belt around a molding drum, comprising:

• placing the master roll on a master roll table;
• feeding the master roll from the master roll table to a belt table situated adjacent to the master roll table;
• cutting out a portion of the master roll placed on the belt table as the sheet-like belt for one full circle of a tire by cutting the master roll between the master roll table and the belt table;
• moving the belt table carrying the cut-out sheet-like belt for one full circle of the tire to a winding position of the sheet-like belt;
• winding the sheet-like belt for one full circle of the tire around a single winding cylinder at the winding position;
• transporting the winding cylinder wound with the sheet-like belt to a place of the molding drum which is a place distant from the winding position;
• and unwinding the sheet-like belt from the winding cylinder and forming the cylindrical belt by winding the unwound sheet-like belt around the molding drum, wherein:
• the master roll is fixed onto the belt table by attraction when the master roll is cut between the master roll table and the belt table;
• the belt table is moved to the winding position of the sheet-like belt while keeping the cut-out sheet-like belt fixed onto the belt table by attraction;
• and the master roll is fixed to the master roll table by a pressing member so that the master roll is pressed closer to the master roll table than when the master roll is in a cutting position between the master roll table and the belt table.
