Patent number: 7850899Abstract: A web is made by first extruding multicomponent filaments from a spinneret and then passing the extruded filaments through a process air shaft. Cold air is directed against the filaments in the process air shaft to cool and aerodynamically stretch the filaments while excluding the entry of other air into the process air shaft. The cooled and stretched multicomponent filaments are then deposited in a mat on a support, and then the mat of multicomponent filaments to a web is consolidated by subjecting it to water jets at a pressure of 10 bar to 200 bar such that the multicomponent filaments fuse together at crossover points and the filaments have a considerable free length between crossover points where they are fused. Finally the web is heat treated to crinkle the filaments thereof and bulk of the web.Type: GrantFiled: February 13, 2007Date of Patent: December 14, 2010Assignee: Reifenhauser GmbH & Co.

Patent number: 7390377Abstract: We demonstrate a new method for joining patterned thermoplastic parts into layered structures. The method takes advantage of case-II permeant diffusion to generate dimensionally controlled, activated bonding layers at the surfaces being joined. It is capable of producing bonds characterized by cohesive failure while preserving the fidelity of patterned features in the bonding surfaces. This approach is uniquely suited to production of microfluidic multilayer structures, as it allows the bond-forming interface between plastic parts to be precisely manipulated at micrometer length scales. The bond enhancing procedure is easily integrated in standard process flows and requires no specialized equipment.Type: GrantFiled: September 22, 2005Date of Patent: June 24, 2008Assignee: Sandia CorporationInventors: Thomas I.

Publication number: 20040121124Abstract: The invention concerns a method for making a sheet of paper comprising at least two crimped cotton-wool-like cellulose plies (20, 40). It consists in: unwinding a first ply (20) in the form of a strip from a reel, embossing it on an embossing unit (10, 12) and forming protuberances at its surface, unwinding a second ply (40) in the form of a strip from a reel, guiding it downstream of the embossing unit (10, 12), superposing the two strips, with their protuberances facing inwards, and in applying a linking means (14, 16) so as to make the two strips integral with each other. Said method is characterised in that immediately upstream of said linking means (14, 16), a tension regulating means (18) is applied in the machine direction on one of the strips, such that the two strips have the same clastic deformation in the machine direction when the linking means is applied. The invention also concerns a product obtained by said method.Type: ApplicationFiled: September 9, 2003Publication date: June 24, 2004Inventors: Michael Basler, Pierre Laurent, Gilles Roussel, Remy Ruppel
