Patent number: 8088316Abstract: The present invention relates to the perforation of nonwovens with a perforating roll and an opposing roll. The perforating roll and opposing roll form a gap, through which a nonwoven being perforated, is guided and perforated. The perforation apparatus comprises a feed device and a withdrawal device. The feed device is arranged such that the nonwoven being perforated advances first onto the opposing roll, before it enters the gap. The withdrawal device is arranged such that after leaving the gap, the perforated nonwoven remains on the perforating roll. Furthermore, a perforation method and a corresponding nonwoven structure are provided.Type: GrantFiled: February 5, 2007Date of Patent: January 3, 2012Assignee: Fiberweb Corovin GmbHInventors: Mathias Muth, Indra Roy, Ralf Sodemann

Patent number: 7390553Abstract: The present invention relates to a perforated thermoplastic structure comprising at least a first layer (8) and a plurality of perforations, which extend through the first layer (8). The perforations have a three-dimensional, preferably approximately conical or cylindrical shape (18). A second layer forms an inner surface (20) of the shape (18), whereas the first layer forms an outer surface (21) of the shape (18). The first layer contains a thermoplastic material, whose melting point is lower than a melting point of the thermoplastic material of the second layer.Type: GrantFiled: July 3, 2002Date of Patent: June 24, 2008Assignee: Fiberweb Corovin GmbHInventors: Mathias Muth, Joachim Bauer, Henning Roettger

Patent number: 7386924Abstract: The present invention relates to perforation device for the manufacture of a perforated nonwoven material, whereby a prebonded nonwoven with embossing points is guided to a nonwoven perforation device, needles of a needle roller engage into the prebonded nonwoven and perforate it, and the perforated nonwoven material then undergoes further processing. A ratio is set between the number of needles to the number of embossed points of between 0.15 and 0.25 and a ratio of hole size to embossed point size of between 0.15 and 0.25.Type: GrantFiled: February 9, 2007Date of Patent: June 17, 2008Assignee: Fiberweb Corovin GmbHInventors: Mathias Muth, Axel Richter, Ralf Sodemann

Publication number: 20060128245Abstract: A method for the manufacture of a perforated nonwoven, whereby perforation means engage into the nonwoven. The perforation means are arranged on a first roller. The perforation means engage through the nonwoven into a surface of a second roller. The perforation means displace fibers of the nonwoven, whereby the perforation means engage in a material on the second roller, such that said means can displace the material when they engage. In addition, a corresponding device and corresponding materials are provided for.Type: ApplicationFiled: July 5, 2003Publication date: June 15, 2006Inventors: Mathias Muth, Ralf Sodemann

Patent number: 5118967Abstract: An adaptive arrangement for the identification of a periodic input signal (U.sub.S), for example, a signal supplied by magnetic field speed sensors. An evaluation circuit (11) is provided for digitizing the signal (U.sub.S) and for detecting the extreme values thereof, an interference-free output signal being present at the output of the evaluation circuit (11) in the event of small interferences which are less than a presettable minimum turn-over voltage (U.sub.M). In the event of larger interferences, subsequent means are provided for detecting the fundamental oscillation of the signal (U.sub.S). The subsequent means (12, 13) include a mean value producing circuit (12) and a comparator (13). The comparator compares the digitized signal (U.sub.SD) with a reference value signal (U.sub.V) which the mean value producing circuit (12) recursively forms from the extreme values of the signal (U.sub.S). The comparator produces an interference-free output signal (U.sub.Type: GrantFiled: October 9, 1990Date of Patent: June 2, 1992Assignee: U.S. Philips CorporationInventor: Mathias Muth
