20120024774 | Filter Medium and Filter Element - A filter medium for removing particles from a fluid flow has a pre-filter layer and a fine-filter layer joined to each other in the flow direction. A first supporting layer is attached to the unfiltered side of the pre-filter layer and a second supporting layer is attached to the filtered side of the fine-filter layer in order to absorb the longitudinal and transverse forces in the event of tensile loading. The traverse force absorbing layer has a greater bending stiffness in a traverse direction while the longitudinal force absorbing layer has a greater bending stiffness in a longitudinal direction. | 02-02-2012 |

20120279186 | Compact Filter, Method for Producing a Compact Filter, and Filter Medium - A compact filter has a compact filter element for exchangeable use in a filter housing and the compact filter element has a filter body of a web-shaped filter medium. The web-shaped filter medium has at least one flat filter medium web and one corrugated filter medium web that are placed onto each other and at least partially connected to each other by ultrasonic welding. At least one of the flat and corrugated filter medium webs is a composite filter medium web of at least two components, wherein at least one component is a synthetic material and one component is a non-synthetic material. The non-synthetic material is a plant-derived material and forms a support of the composite filter medium web and the synthetic material is a synthetic layer applied on the support. | 11-08-2012 |
20130008849 | Device for Folding a Web-Shaped Filter Medium and Method for Producing a Filter Element Folded in a Zigzag Shape - A device for folding a web-shaped filter medium of a filter element has an energy-introducing embossment unit and a feed device that feeds a web-shaped filter medium to the embossing unit where folding lines are embossed into the web-shaped filter medium. A folding device is provided that folds the web-shaped filter medium along the folding lines. The energy-introducing embossment unit is provided to fuse layers of the multi-layer filter medium along the folding lines during embossment of the folding lines. | 01-10-2013 |
