Patent number: 11795593Abstract: A filter medium (10) for filtering a fluid, in particular for use in an interior air filter (32), comprises a spun-bonded nonwoven formed at least in part of multi-component segmented pie fibers (1) having at least a first plastic component (2) and a second plastic component (3). The multi-component fibers (1) are largely non-split, and in order to manufacture same, segmented pie filaments are spun in a spun-bonding process (S4) to form a spun-bonded nonwoven (10). The segmented pie filaments then form the multi-component fibers (4), the first plastic component (2) and/or the second plastic component (3) being made in particular of a polypropylene.Type: GrantFiled: September 27, 2019Date of Patent: October 24, 2023Assignee: MANN+HUMMEL GmbHInventors: Stefan Orendt, Thomas Pemsel

Patent number: 11702780Abstract: An apparatus for making a nonwoven fabric from thermoplastic fibers has a spinneret for spinning fibers into continuous filaments and a cooler for cooling the filaments. The cooled filaments are then deposited on a conveyor to form a nonwoven web. A first consolidator surface treats the nonwoven web with a hot fluid or hot air as it is conveyed on the conveyor. A second consolidating downstream of the first consolidator has a dual-belt furnace in which the nonwoven web is passed between two circulating belts or continuous belts for surface treating the nonwoven web with a hot fluid or hot air and for applying surface pressure can be applied to the nonwoven web at the same time.Type: GrantFiled: March 29, 2021Date of Patent: July 18, 2023Assignees: REIFENHAEUSER GMBH & CO. KG MASCHINENFABRIK, MANN + HUMMEL GMBHInventors: Claudio Cinquemani, Detlef Frey, Stefan Orendt, Thomas Pemsel

Patent number: 10995436Abstract: The invention relates to a method for producing a nonwoven fabric from fibres, wherein the fibres are spun by means of at least one spinneret, are cooled and then deposited on a collection device to form a nonwoven web. The nonwoven web undergoes hot fluid bonding during at least two consecutive bonding steps. In a first bonding step, the surface of the nonwoven web is subjected to a hot fluid and, in a second bonding step, the surface of the nonwoven web is also subsequently subjected to a hot fluid and, in addition and at the same time, surface pressure is exerted on the nonwoven web.Type: GrantFiled: February 23, 2018Date of Patent: May 4, 2021Assignees: REIFENHAEUSER GMBH & CO.
