A carrier is configured to hold a product carried on a material strip during horizontal conveying of the material strip. The carrier comprises a first holding member positioned on the upper or lower side of the product on the material strip during the horizontal conveying of the material strip and extending along a conveying direction of the material strip. A first contact surface is formed on the side of the first holding member facing the product, the first contact surface is configured to contact the product during the horizontal conveying of the material strip to limit the up and down bouncing movement of the product.

A method of manufacturing a stacked core includes forming a first pilot hole in a metal plate, forming a worked portion of the metal plate in a state in which a first pilot pin is inserted into the first pilot hole, the worked portion being displaced relative to a plane of the metal plate, press-fitting the worked portion of the metal plate to reposition the worked portion to extend along the plane of the metal plate, forming a second pilot hole in the metal plate after press-fitting the worked portion of the metal plate, and forming a blanked member by blanking the metal plate in a state in which a second pilot pin is inserted into the second pilot hole, the blanked member including the worked portion.

A transfer press includes a press machine that moves a slide up and down in accordance with pressing motion, and a transport device that moves a retainer in accordance with transfer motion to transport a workpiece. The transfer press includes a creation unit, a determination unit, and a phase adjustment unit. The creation unit creates a three-dimensional operating curved surface based on the provisionally set pressing motion and the provisionally set transfer motion. The determination unit compares a standard upper die interference curved surface with the operating curved surface in the same three-dimensional coordinate system to determine whether the operating curved surface is present within an interference region of the standard upper die interference curved surface. The phase adjustment unit changes a relative phase of the transfer motion relative to the pressing motion when the operating curved surface is present within the interference region.
