Patent number: 10487423Abstract: A sensor yarn (10) having a thread core (11) around which first and second conductors (12, 13) are helically wound. The two conductors (12, 13) are electrically insulated from each other and from the thread core (11). The two conductors (12, 13) form a capacitive component (15) together with the thread core (11). In one embodiment, the sensor yarn (10a) has a capacitance (Cl) per unit of length that changes in the direction of extent (E) of the sensor yarn. This can be accomplished by a change in the winding geometry of the first or second conductors (12, 13) or by a change of the relative permittivity (E) of the sensor yarn (10). In another embodiment, the sensor yarn (10b) has photosensitive material (30) and a length change is effected by an incident to the light (L). As a result of a length change or other deformation of the sensor yarn (10a, 10b), the total capacitance (CG) of the sensor yarn (10a, 10b) changes, which can be determined by means of an evaluating unit (17).Type: GrantFiled: March 20, 2015Date of Patent: November 26, 2019Assignee: Deutsche Institute für Textil-und Faserforschung DenkendorfInventors: Christoph Riethmüller, Bastian Baesch, Simon Hoinkis

Patent number: 10443809Abstract: An arrangement (10) for generating a light effect (26) includes an obscuration sheet material (11) and a divergence sheet material (12) arranged in spaced apart relation to a rear side (23) of an effect sheet material (13). The obscuration sheet material (11) has at least one transmission region (17) and at least one shielding region (18). On the light entry side (15), which faces away from the effect sheet material (13), light (L) impinges on the obscuration sheet material (11) and is severely reduced or completely shielded in shielding region (18), while light (L) passes through the at least one transmission region (17). By means of the divergence sheet material (12), divergent light rays (LD) are produced at the corresponding transmission region (17), which divergent light rays impinge on the rear side (23) of the effect sheet material (13) and generate a light effect (26) for a viewer (25) looking at the viewing side (24).Type: GrantFiled: April 7, 2015Date of Patent: October 15, 2019Assignee: Deutsche Institute für Textil—und Faserforschung DenkendorfInventors: Christoph Riethmüller, Bastian Baesch, Holger Illg

Publication number: 20180044831Abstract: The invention relates to an arrangement comprising a visible seam, which is arranged in a sheet material part. The arrangement also includes a lighting apparatus, which is arranged beneath an underside of the sheet material part. The visible seam has an upper thread and a lower thread. The lower thread extends along the underside of the sheet material part in a direction (R). The upper thread has first thread portions along the upper side of the sheet material part and is guided, at stitch holes formed during the sewing process, through said stitch holes via second thread portions. By means of the lighting apparatus, emitted light passes into the second thread portions, into the stitch holes, and from there into the first thread portions. Some of the light propagates along the first thread portions, starting from an adjacent second thread portion, whereas another portion of the light exits from the first thread portion. In this way, the upper thread of the visible seam is illuminated.Type: ApplicationFiled: August 10, 2017Publication date: February 15, 2018Inventors: Udo Kansteiner, Frank Blockhaus, Julia Schmidt, Holger Wagner, Christoph Riethmuller, Benjamin Pohl

Patent number: 7665682Abstract: An overend take-off crosswound bobbin and a method for its production are designed in such a way that the density of the finished crosswound bobbin is increased and the run-off characteristics during further processing are optimized. For this purpose, in one variant parallel windings are introduced at intervals. In another variant, when the bobbin diameter is small the yarn is wound on at a smaller pitch angle than for a larger diameter. Furthermore, a traversing stroke which is reduced by comparison with the bobbin width is displaced along the bobbin width.Type: GrantFiled: February 25, 2005Date of Patent: February 23, 2010Assignee: Deutsche Institute fuer Textil- und Faserforschung Stuttgart Stiftung des oeffentlichen RechtsInventors: Gerd Stahlecker, Gernot Schäffler, Christoph Riethmüller

Patent number: 7410116Abstract: A system for winding a cross-wound bobbin has a rotatably supported tube holder that is intended to receive a tube. The yarn guide element that serves the purpose of shogging the yarn moves in the direction parallel to the axis of rotation of the tube and is made to execute the oscillating reciprocating motion with the aid of a work cylinder. The work cylinder has the advantage that for braking the kinetic energy at the turning point of the yarn guide element, no additional external energy must be applied. It suffices for the applicable cylindrical chamber to be blocked off. Moreover, the gas compressed in the process can be used to accelerate the piston in the opposite direction. The stored braking energy also can be used simultaneously as acceleration energy. Since in the creation of a cross-wound bobbin many thousand such changes of direction occur, the energy savings are substantial.Type: GrantFiled: March 22, 2006Date of Patent: August 12, 2008Assignee: DITF Deutsche Institute fur Textil- under FaserforschungInventors: Heinrich Planck, Christoph Riethmuller, Helmut Weinsdorfer
