| 20100132521 | COMPRESSED HEAT INSULATION HOUSING - The invention relates to an assembly comprising, on the one hand, a tubular compressed mineral wool felt element and, on the other hand, at least one means of maintaining the compression state of the said felt. The maintaining means may be a film surrounding the felt element on its cylinder-shaped surface. The assembly may be used as an insulating pipe section for pipework. The invention also relates to a method of producing annular elements, by way of punching, where the starting material is a web of bonded fibrous material, such as tempered mineral wool. A punching tool in the form of at least one punch knife which is mounted on a press plate is pressed through the web then pulled out again. | 06-03-2010 |
| 20110000349 | HYDRAULIC FINE BLANKING HEAD FOR A PRESS AND METHOD OF ITS INFEED - Disclosed is a hydraulic fine blanking head for a mechanical press and [a] an infeeding method for same. The hydraulic fine blanking head includes an adjusting mechanism having an adjusting nut provided with an internal motion thread engaged with external motion threads on a main cylinder, the adjusting nut being turnable around a stroke axis, a sprocket wheel rotatable at a frontal surface of the adjusting nut, a hydraulic motor driving the sprocket wheel, and a brake for the motor shaft. Axial backlash between the respective 1 motion threads is prohibited by a pressure generated by a flow of pressurized hydraulic fluid which also generates a part forming force in the head. A conduit in communication with a hydraulic system and the interior of the head delivers the locking pressure, locking the threads against the backlash. Removal of pressure unlocks the threads. Infeed of the main cylinder with regard to the ram is adjustable by switching the motor and the brake on and off. | 01-06-2011 |
| 20110162497 | LEG-SURROUNDING OPENING FORMING APPARATUS AND METHOD OF MANUFACTURING ABSORBENT ARTICLE - A leg-surrounding opening forming apparatus ( | 07-07-2011 |
| 20110219926 | TOOLING ASSEMBLY, BLANKING TOOL THEREFOR AND ASSOCIATED METHOD - A blanking tool is provided for cutting blanks from a sheet of material. The sheet of material includes a product area where the blanks are located, and a web area, which is the area between the blanks. The blanking tool includes a shear having first and second opposing sides, an outer diameter, and an inner diameter. A plurality of contact surfaces are disposed on the second side of the shear. The contact surfaces engage only the web of the material. A tooling assembly is also disclosed, which includes first and second tooling coupled to first and second opposing portions, respectively, of a press and being structured to cooperate to engage the sheet of material therebetween. The blanking tool is coupled to the first tooling, and the shear of the blanking tool cooperates with a portion of the second tooling to cut the blanks from the material. | 09-15-2011 |
| 20120227555 | INSERT MEMBER, APPARATUS FOR BLANKING PRINTED CIRCUIT FILM HAVING THE SAME AND METHOD OF BLANKING PRINTED CIRCUIT FILM USING THE APPARATUS - An apparatus for blanking a printed circuit film includes a die unit and a punch unit movable with respect to the die unit. The die unit includes a plate, and an insert member which is on a top surface of the plate and supports a region of a base film which is punched. The insert member supports the base film including a plurality of printed circuit films, and as a punch is lowered, the punch punches the base film and is inserted in an opening of the insert member so as to blank the printed circuit film. The insert member further includes a plurality of assembled detachable frames which define the opening of the insert member. | 09-13-2012 |
| 20120272802 | DIE CUT WITH COMMON BLADES - The present invention is generally directed to a die cut assembly for a roller die cutting machine having a base member, a cutting rule, and a compressible top layer. Base member is generally a rectangular shape, having a length, to width and thickness. A cutting rule including a cutting edge is formed into a pattern containing a plurality of geometric shapes. The pattern containing geometric shapes is formed to include each geometric shape sharing a common point when the shape allows it. Cutting rule is generally coupled to the base member at a skew wherein no side of the pattern is transverse to the length of the base member. The compressible top layer is coupled to the base member. Generally, cutting rule nests in compressible top layer and compressible top layer extends beyond the cutting edge of the cutting rule. | 11-01-2012 |
| 20130047807 | METHOD OF PUNCHING DAMPER WITH USE OF HOLLOW PUNCH, PUNCHING APPARATUS FOR THE METHOD, AND ATTACHING APPARATUS WITH THE PUNCHING APPARATUS - A method punches a damper out from a damper material that is detachably attached on a flexible exfoliative member through an attaching surface of the damper material with use of a hollow punch. The method includes steps of setting the damper material on a supporting surface, positioning a projection part between the exfoliative member and the supporting surface, and punching the damper out from the damper material by cutting the damper material around the projection part by the hollow punch without punching the exfoliative member. | 02-28-2013 |
| 20130186245 | PUNCHING APPARATUS AND METHOD - A punching apparatus includes a plurality of punches for punching a workpiece, a pad, and a single piston supporting the pad. The punches are disposed on a top surface of a portion of the pad. The top surface has a circumference circumscribing circumferences of outermost ones of the punches. A diameter of the piston is larger than a diameter of the portion of the pad. | 07-25-2013 |
| 20130255457 | MOVABLE BLADE NOT CAUSING ABRASION OF FIXED BLADE OVER LONG PERIOD OF TIME, SHEET CUTTING DEVICE PROVIDED WITH MOVABLE BLADE, AND PRINTER PROVIDED WITH SHEET CUTTING DEVICE - A pair of guide portions | 10-03-2013 |
| 20140283661 | PUNCH UNIT, SHEET POST-PROCESSING APPARATUS HAVING THE SAME, AND METHOD OF PUNCHING SHEETS - A hole punch unit has a punching section, a longitudinal registering mechanism, and a transverse registering mechanism. The registering mechanisms incline the punching section in accordance with a skew of a sheet. The punching section thus corrected in position punches the sheet. The punching section is corrected in position, at both the leading edge of the sheet and the trailing edge thereof, thus increasing the precision of positioning the punching section and shortening the time required to position the punching section. | 09-25-2014 |
| 20150053059 | DEVICE AND METHOD FOR TRANSFERRING WORKPIECES INTO AND OUT OF A TOOL - A rotary slide moves blanks cyclically from stage to stage of a cutting and processing tool, Work pieces are transferred in and out of the tool, without moving the slide in and out of the tool. The slide has a plurality of transfer openings and a discharge opening. individual processing stages, including a discharge stage, are designed as separate components that support one another. The stages are arranged about a rotating axis of the slide. The transfer openings and the discharge opening lie in a circular path that coincides with circular paths of active elements of the cutting stage, the processing stages and the discharge stage. The openings have a distance from one another that is identical to the distance of the active elements in the circular paths. | 02-26-2015 |
