20140093603 | Filtration Apparatus with a Sealing Device - A polymer filtration apparatus for sealing a slide plate translatable across a bore of an extrusion or mold machine, includes an annular seal having a sealing surface which is biased against the slide plate by a spring mechanism. The annular seal has a thrust surface which is angled relative to the sealing surface and the thrust surface is located at an opposite axial end of the annular seal from the sealing surface. The spring mechanism can be a single spring with overlapping tangs or a multiple spring assembly in overlapping relationship, with or without tangs, to form a continuous barrier. The spring assembly is used to exert a radial force against the thrust surface of the annular seal to bias the seal in an axial direction against the downstream slide plate. In operation, pressurized polymer melt in the extrusion bore further biases the spring against the annular seal which is then transferred to the seal and the slide plate. | 04-03-2014 |

20090104301 | DEVICE FOR MELT SPINNING OF A LINEAR FILAMENT BUNDLE - A device for melt spinning a linear filament bundle has a spinning shaft for mounting a longitudinal spinning nozzle group, having a nozzle plate including a plurality of nozzle openings on a bottom, and an inlet plate having at least one inlet channel on a top. A distribution chamber is provided between the inlet plate and the nozzle plate, which is connected to the inlet channel in the inlet plate and the nozzle openings in the nozzle plate. The inlet plate has multiple inlet channels provided at a distance to one another in longitudinal direction of the spinning shaft. Multiple distribution chambers arranged next to one another are provided in longitudinal direction of the spinning shaft. The inlet channels each end in one of the distribution chambers. | 04-23-2009 |

20140050812 | EXTRUSION MOLDING APPARATUS AND MANUFACTURING METHOD FOR GREEN HONEYCOMB MOLDED BODY USING SAME - The extrusion-molding device of the invention is for producing a green honeycomb molded body with a cell structure, and the device includes a housing, a screw, a die with slits, a resistance tube and a fragmenting board having through-passages through which a raw material composition passes from the upstream end side to the downstream end side. The through-passages of the fragmenting board have upstream channels composed of a plurality of flow passages extending downstream from the upstream end side, and downstream channels extending up to the downstream end side and having flow passage cross-sectional shapes different from those of the upstream channels. | 02-20-2014 |

20090285924 | JIG FOR EXTRUSION-FORMING - A jig for extrusion-forming is to be used to obtain a formed ceramic article by extrusion-forming. The jig for extrusion-forming includes a cylindrical extrusion passage into which kneaded clay is fed; a filtering mesh which is arranged to cover an inlet of the extrusion passage and which removes coarse particles and foreign matter from the clay; a first porous plate brought into contact with the filtering mesh and provided with a plurality of through-holes; a second porous plate arranged to leave a space from the first porous plate in the extrusion passage and provided with a plurality of through-holes; and a die arranged to leave a space from the second porous plate in the extrusion passage, and the arrangement of the through-holes of the first porous plate does not coincide with the arrangement of the through-holes of the second porous plate in the extruding direction of the clay. | 11-19-2009 |
