Abstract: A cushioning structure includes a first layer of a three-dimensional structured mat of extruded entangled filaments, the cushioning structure includes a second layer of a three-dimensional structured mat of extruded entangled filaments, and the cushioning structure includes an intermediate layer between the first layer of the three-dimensional structured mat and the second layer of the three-dimensional structured mat.

Abstract: A composite structure for a floating floor system including at least one layer of force muting material and a layer of formwork, wherein the layer of formwork is located on the at least one layer of force muting material wherein the layer of formwork is a half closed folded honeycomb structure or a relaxed honeycomb structure.

Abstract: A folded core structure formed from an uncut flat body, has a plurality of consecutive 3D-structures and connecting areas each formed by plastic deformation, and includes first and second primary surfaces oriented plane-parallel to each other. The first and second primary surfaces include a first secondary surface extending over the entire width of the folded core structure and extending over a part of the length of the folded core structure. The first secondary surface is oriented parallel to the first primary surface, and the first secondary surface is located at a distance from the first primary surface between the first and second primary surfaces. A channel for fluid flow at least along the width of the folded core structure is provided. The first and/or second primary surface is/are configured to provide dimensional stability under a compression force applied perpendicular to the first primary surface of the folded core structure.

Abstract: A composite including a first fabric layer having a water permeability W1 and adjacent to a second fabric layer having a water permeability W2, wherein W2 and W1 fulfill the relation W2<W1, and wherein the composite is folded to exhibit a folded structure, wherein the folded structure includes a plurality of folds. Furthermore, a greening system, a device for thermal insulation, a device for acoustic noise insulation and a multifunctional device for greening and/or thermal insulation and/or acoustic insulation including the composite described before.

Abstract: Open end spinning apparatus is provided which includes a magnetic reed switch for controlling sliver feed. A yarn sensor magnet attached to a movable yarn sensor engageable with a running yarn is disposed so as to open the magnetic switch and interrupt sliver feed upon occurrence of a yarn breakage. In order to prevent the need for moving the yarn after a piecing operation so as to properly engage the yarn sensor, an auxiliary magnet is provided which is movable into position to magnetically move the yarn sensor away from a blocking position in front of the yarn takeoff passage at a spinning unit. The auxiliary magnet is controlled by way of its position, and/or its magnetic field strength, so as to also selectively control the operation of the magnetic reed switch during piecing operations, while maintaining the sensor magnet, and yarn sensor out of a blocking position in front of the yarn takeoff passage.

Abstract: In start-spinning a thread, which has to be performed after a condition in which the entire machine has been stopped or after a thread break, the individual working conditions have to be maintained as precisely as possible in order to keep the start-spinning points produced at the same spinning point and at different spinning points as uniform as possible and in order to ensure that they are of sufficient strength. An important criterion in this connection is the size and thickness of the ring of fibers located in the spinning rotor, on which the end of the thread is placed after it has been returned and from which the end of the thread is then drawn off again. This ring of fibers significantly influences the appearance and quality of the start-spinning point of the thread.
