Abstract: Disclosed is a tool set for use in forming the components of a decorating nozzle from sheet metal. A tool-mounting plate mountable on the headstock of a metalworking lathe is configured with concentric grooves into which circular ribs on the tools can locate. Transverse formations prevent relative rotation between the tool and the tool-mounting plate. A method of forming nozzles comprises rolling a metal blank onto the surface of a forming tool as the tool is rotated in the lathe. Successive tools are used to achieve the desired shape.

Abstract: Disclosed is a device and method for forming a curl in a closable container. A process of forming a pre-curl is used, which is followed by a second separate step of forming the completed curl. The two-step process provides for higher tolerances with respect to the shape of the curl that allows the curl to be used as a sealing surface for a recloseable metal bottle. A three-step process provides for even greater tolerances and reduces longitudinal forces by completing the curl using lateral forces.

Abstract: The present invention is a method for forming sheet material into contoured parts. The invention method includes these steps: A die is fashioned having an outside surface corresponding to the inside surface of the desired part. A plastically deformable sheet of material is clamped to the die so that the material is tangent to the die at a tangent area. A forming path is defined that follows the part's outside surface definition beginning at a point adjacent to the tangent area and tracing around the tangent area in circuits that incrementally offset away from the tangent area until all of the outside surface of the part is traced. A forming tool is then moved along the forming path so that the end of the forming tool presses the sheet material against the die thereby gradually forming the sheet material against the die to produce a finished formed part.

The proposal is made that the hub part (14) of the bearing (12) encompassing the shaft (10) have at least one axial surface (20), against which a projection (24, 30) rests, which is produced from the shaft (10) by means of plastic deformation and prevents an axial movement.

Abstract: An roller-flanging device for flanging at least an end region of a cylindrical body includes a receptacle having a longitudinal axis common with the cylindrical body being flanged. Flange rollers are rotatably seated in the receptacle about the common longitudinal axis, and roll along a surface of the cylindrical body. The flange rollers each have a part with a cylindrical surface and a flange collar for forming a flange contour on the cylindrical body. At least one limiting body is disposed between contiguous ones of the flange rollers, and extends inwardly toward the common longitudinal axis beyond the circumscribed cylindrical surface of the cylindrical parts of the flange rollers at least when forming the flange. The at least one limiting body prevents burrs or material from the cylindrical body from reaching or extending beyond the cylindrical surface of the flange rollers, and assures a uniform flange diameter.

Abstract: A process and apparatus for working an edge portion of a flange positioned on an open end of a container to prepare the flange for end-piece attachment by shaping such edge portion and improving flange uniformity, and, if desired, configuring the flange into a desired angular orientation. In one embodiment a plurality of working rollers are positioned radially outward from the edge of the flange and a mechanism is used to force at least portions of the flange toward the rollers. When at least a portion of the flange engages with at least one of the rollers as the rollers are rotated relative to and about the flange, flange uniformity is improved as the flange edge is shaped by such roller. In the event the flange continues to be forced toward the working rollers, remaining portions of the flange may approach and possibly contact the rollers to be shaped and worked thereby while the outward radial movement of the initial contacting edge portion is restrained, thereby further improving flange uniformity.

Abstract: A continuous rotary machine for roll flanging the ends of cylindrical container bodies transports the container bodies in a star wheel while applying a roll flanging tool head to the end portion of the container body in two stages. In the first stage, the tool head forms a small flange that acts as a stress ring to maintain the cylindrical body in circular configuration at the open end, and the stress ring is ironed. In the second stage, the tool head advances by a greater distance to form a larger portion of the flange, and this flange is ironed. Both ends of a cylindrical container body may be simultaneously flanged by this method, in which case the opposite flanging heads rotate in opposite directions at substantially the same speed. The rotary apparatus provides a spindle/ram assembly on a turret for supporting and moving the flanging heads. A cam operates the axially movable ram portion and is located radially outside the ram for greater accuracy in the cam profile.

Abstract: Three cylindrical rollers are rotatably mounted equidistant from the center of a hollow tool head on radii spaced 120.degree. apart. Each roller has a thin flange; the three flanges lie in a single plane to form an internal circumferential rib in a rotating tubular workpiece. The tool head has two complementary parts with two rollers in one part of the head and one roller in the other part; the two parts are joined by a hinge. A second hinge, located so the rollers are between the two hinges, connects one of the parts to a tool bar mounted in a lathe tool holder. The axes of rotation of both hinges and all three rollers are parallel. A hole exposing equal portions of the three roller flanges is located in the center of the tool head. The two hinges permit the tool head to be opened and rotated slightly downward, taking the roller flanges out of the path of the workpiece which is supported on both ends and rotated by the lathe.
