| 20090078021 | Metal sheet pressing method - This invention provides a metal sheet pressing method of precision-pressing a metal sheet, wherein after a metal sheet ( | 03-26-2009 |
| 20090090160 | Process for obscuring corrugations in a window well - A process for obscuring corrugations in a window well employing painting on a metal surface a solid variegated pattern using perspective to create a three-dimensional effect on the face. Preferably, such painting occurs prior to the forming of the window well. In a preferred continuous process, a roll of metal is cut prior to the forming into a piece having such dimensions as to permit the piece to be formed into a single window well. The preferred metal is steel. And the solid variegated pattern using perspective to create a three-dimensional effect on the face can be a pattern of brick, stone, or the like, with granite being the preferred pattern. | 04-09-2009 |
| 20090205395 | METHOD AND APPARATUS FOR CORRUGATING SHEET METAL - An apparatus for bending sheet metal comprises a housing, a first shaft and second mounted in the housing, a motor, a first gear mounted on the first shaft, and a second gear mounted on the second shaft. The motor rotates both the first gear and the second gear. The first gear and comprises a first plurality of components and the second gear comprises a second plurality of components. The first gear and the second gear are capable of engaging sheet metal passed between the gears while they are moving. The first and second plurality of components are capable of being configured to change a bend radius, a wavelength of waves formed in the sheet metal, and a distance between the first shaft and the second shaft can be adjusted to change an amplitude of waves formed in the sheet metal engaged by the first and second gears. | 08-20-2009 |
| 20110203344 | Stamping -Bending Method - The instant invention relates to a multi-stage stamping-bending method for introducing a primary and at least one secondary structure into a band-shaped metal foil, wherein, after passing through the multi-stage stamping-bending method, the metal foil encompasses at least two 180° bends between primary and at least one secondary structure along the wave train of the primary structure within one wave of the primary structure, in the case of which the primary structure is introduced into the metal foil during a first bending method step so as not to be formed completely in all of its areas, in the case of which the primary structure is embodied completely in its remaining areas during a subsequent second bending method steps and in the case of which the at least one secondary structure is introduced into the metal foil in a completely formed manner during a subsequent third bending method step, wherein the metal band passes through the method steps back-to-back. | 08-25-2011 |
| 20110296897 | METHOD FOR THE PRODUCTION OF A FASTENING ELEMENT FOR DRY CONSTRUCTION ELEMENTS - A method for the production of a fastening element for dry construction elements involving feeding a flat sheet metal material through a nip formed between a top roller having first teeth and a bottom roller having second teeth, in order to create depressions and elevations as well as slanted sliding surfaces. | 12-08-2011 |
| 20130255347 | METHOD AND APPARATUS FOR CREATING FORMED ELEMENTS USED TO MAKE WOUND STENTS - A method for forming a wave form for a stent includes moving a first forming portion of a first forming member across an axis along which a formable material is provided in a first direction substantially perpendicular to the axis to engage and deform the formable material while engaging the formable material with a first forming portion of the second forming member. The method includes moving the first forming portion of the first forming member and the first forming portion of the second forming member across the axis in a second direction that is substantially opposite the first direction to draw and form the formable material over the first forming portion of the second forming member, disengaging the first forming member from the formable material, and rotating the first forming member to position a second forming portion of the first forming member to face the formable material. | 10-03-2013 |
| 20150290692 | DEVICE FOR MOLDING AND METHOD FOR MOLDING METAL PLATE - A protruding portion is formed in a metal plate material by use of a plurality of molding tools each of which has a die and a punch. In a first step, an initial protruding portion is formed in the metal plate material by use of a first molding tool. In this step, a top of the initial protruding portion is formed to be thinner than other parts. In a second step, a sidewall of the initial protruding portion is rolled out by use of a second molding tool, and the protruding portion is formed. | 10-15-2015 |
