Abstract: A block baling press has a bale chamber and a baling ram moveable in the bale chamber in an oscillating manner to compress bale material. An end face of the baling ram facing the bale material is divided into ram segments separated from one another by needle slots. At least a first needle slot is flanked by ram segments with a profiling transverse to the first needle slot. The profiling brings about a weaker compression of the bale material in an edge region of the ram segments adjacent to the first needle slot than in a region of the ram segments spaced apart from the first needle slot. Bales are obtained in which zones of high compression and low compression alternate across the width of the bale chamber. The bales are held together by twine placed around the zones having low compression.

Abstract: A die cushion-cum-slide cushion device selectively opens and closes a flow channel between a hydraulic pump/motor driven by a servo motor, and hydraulic cylinders that generate slide cushion force, or a flow channel between the hydraulic pump/motor, and hydraulic cylinders that generate die cushion force, by switching a selector valve. Before applying the slide cushion force is started, the servo motor is controlled to allow the hydraulic cylinders to generate required slide cushion force through a check valve. While the slide cushion force is applied, hydraulic circuits, each of which includes a logic valve, control pressure of the hydraulic cylinders, and hydraulic circuits, each of which includes the servo motor, control die cushion pressure of the hydraulic cylinders.

Abstract: A method to produce a molded part having at least two regions of different strength using a press-hardening tool. A heated blank is formed in the tool during a forming step and held therein for heat-treating during a cooling step. At least one region of lower strength is cooled more slowly than at least one region of higher strength. During the forming step, the entire blank is in contact with a molding surface of the tool. Then, the tool surface is changed such that one or more regions of lower strength have no tool contact during the cooling step. The tool surface associated with the one or more regions of lower strength is provided by tool segments that are adjustable relative to the remaining tool surface. The molding surface of the one or more tool segments is larger than the region of lower strength associated with such tool segment.

Abstract: An apparatus and method of forming a metallic cup that is subsequently reformed into a container body. More specifically, an apparatus and methods used to form a metallic cup with a reformed bottom having an inwardly oriented projection are disclosed. The inwardly oriented projection reduces a height of the metallic cup but utilizes the same amount of metallic stock material as a taller cup with substantially the same diameter that does not have an inward projection. The inwardly oriented projection thus allows the use of a conventional bodymaker and other can manufacturing tools to convert the cup into a container body of a preferred size and shape.
