[Object] An issue is to provide a member that exhibits high load capacity and rigidity when joined to another member.

[Solution] Provided is a member 1 having a transverse cross section that includes a top sheet 2, upper ridgelines 4, vertical walls 3, lower ridgelines 5, and floor flanges 9, and including, on at least one end portions in the extending directions of the upper ridgelines 4, a top sheet flange 11 via a top sheet ridgeline 6 and vertical wall flanges 10 via vertical wall ridgelines 7, in which the vertical wall flange 10 and the floor flange 9 are continuous, and in end portions of the upper ridgelines 4 and the lower ridgelines 5, the sum total R of the radii of curvature of corner portions of the vertical walls and the sum total L of the widths of the top sheet 2 and the vertical walls 3 in an end portion of the member have the relation of R/L0.13. The member 1 is produced by performing a first step of performing press molding on a blank 26 to form, in a shrink flange manner, flange ridgelines 8 and thereby producing an intermediate molded product 27 including at least the flange ridgelines 8 and a second step of performing press molding on the intermediate molded product 27 to produce the member 1.

A rigid sheet blank includes a first section configured to be bent about a first axis and a second section configured to be bent about a second axis. The first section has a peripheral edge and at least one tab extending from the peripheral edge. The at least one tab is bendable by hand. The second section defines at least one opening configured for receiving a respective one of the at least one tab during bending of the rigid sheet blank.

The invention relates to a method (100) for producing a container (102) having an upper part (108), a lower part (110) and a receiving element (112), said method having at least the following steps: the lower part (110) is created (114) from a first starting material (200) in a first processing region (115a) of a processing device (115); the upper part (108) is created (116) from a second starting material (202) in a second processing region (115b) of the processing device (115); the receiving element (112) is fed (118) into the first processing region (115a) of the processing device (115); the lower part (110) receives (120) the receiving element (112) in the first processing region (115a) of the processing device (115); the upper part (108) is fed (122) from the second processing region (115b) of the processing device (115) into the first processing region (115a) of the processing device (115); and the upper part (108) and the lower part (110) are joined together (124) to form the container (102) in the first processing region (115a) of the processing device (115).

An enclosure for a radiographic device includes a bottom panel, a plurality of sidewalls integrally formed with the bottom panel, whereby the plurality of sidewalls and the bottom panel define a unitary body, and a top panel joined to the plurality of sidewalls and defining an internal space therebetween for housing a radiographic device.

A method of forming a pair of opposed side walls and a pair of opposed end walls of a sheet metal casket shell from a single piece of sheet metal. The piece of sheet metal has opposite ends and a length equal to the combined length of the pair of side walls and the pair of end walls of the casket shell to be formed. The opposite ends of the piece of sheet metal are secured together to form a tube. A roll forming roller is positioned in an interior of the tube. A female die configured to produce a desired profile for the side walls and the end walls of the casket shell is positioned around an exterior of the tube. The roller is moved outwardly so as to contact an interior surface of the tube and deform the tube toward a die cavity of the female die. The roller is rolled around a perimeter of the interior of the tube so as to deform the perimeter of the tube toward the die cavity of the female die. The desired profile for the side walls and the end walls of the casket shell is thereby produced.
