| 20090031693 | Method and Entanglement Nozzle for Reproducing Knotted Yearn - The invention relates to an entanglement nozzle and to a method for producing fine knotted yarn with highly regular knots by means of air jets comprising a yarn treatment channel. According to said method, air is blown transversally to the yarn treatment channel. Said blown air forms a respective double swirl both in the yarn transport direction and against the yarn transport direction for creating the knots. According to the invention, upon entry into the yarn treatment channel, the blown air is converted into two intense, stationary eddy currents that are not disrupted by filament bundles, in an air swirling chamber that only extends for a short distance in the longitudinal direction of the yarn channel. The regularity of the knots can be significantly improved, despite the tiny dimensions of the air swirling chamber, which projects beyond the longitudinal wall of the yarn channel for a maximum 0.5 mm or for 5% to 22% of the width (B) of said channel. It is also possible to create hard or soft knots that can be subsequently undone. | 02-05-2009 |
| 20120192541 | Component For An Air Jet Spinning Device - A component for an air jet spinning arrangement, in particular a spindle point, comprises a yarn withdrawal channel having an entry opening for drawing a yarn out of a vortex chamber of the air jet spinning arrangement. The component comprises at least one air outlet opening connected to the yarn withdrawal channel for discharging air from the yarn withdrawal channel during a piecing process. The component may comprise an injector channel for feeding back a yarn end back counter to the withdrawal direction during a piecing process. The injector channel, which is connectable to a compressed air source, can be connected by means of an opening to the yarn withdrawal channel and be positioned opposite the entry opening of the yarn withdrawal channel. The air outlet opening can be connected to the yarn withdrawal channel between the entry opening of the yarn withdrawal channel and the mouth of the injector channel. | 08-02-2012 |
| 20130042593 | TIRE HAVING A STRUCTURAL ELEMENT REINFORCED WITH A HYBRID YARN - A tire includes at least one structural element which includes at least one reinforcing element which includes at least one hybrid yarn, the at least one hybrid yarn including a plurality of filaments obtained from at least one first multifilament yarn having a first initial tangent modulus and at least one second multifilament yarn having a second initial tangent modulus, the first and the second initial tangent modulus being different from each other, each one of the first and the second multifilament yarn including a plurality of individual filaments, the individual filaments of each one of the first and the second multifilament yarns being at least partially intermixed with each other. The tire may be a high performance or ultra high performance tire, or a tire suitable for being employed in sporting contests such as track motor races, or a tire suitable for sports utility vehicles. | 02-21-2013 |
