Patent number: 7594382Abstract: A joining method wherein fibers of a fiber band are wound around an auxiliary thread threaded into a spinning device and drawn through a spinning cone. The newly spun thread is separated from the auxiliary thread and connected to the end of an upper thread. A spinning device is provided for a jet spinning machine for carrying out such method, comprising a first clamping device for temporary clamping of the upper thread and a second clamping device for temporary clamping of the auxiliary thread. A jet spinning machine for carrying out the method has a mechanism for storing the auxiliary thread and the newly spun thread, a mechanism for separating the auxiliary thread from the newly spun thread, and a splicing mechanism for connecting the newly spun thread to the upper thread, all arranged only on at least one operating carriage displaceable along multiple spinning stations.Type: GrantFiled: March 28, 2006Date of Patent: September 29, 2009Assignee: Oerlikon Textile GmbH & Co. KGInventors: Thomas Weide, Helmut Feuerlohn

Patent number: 6820407Abstract: An opening arrangement for an open-end spinning device with a rotating opening roller having opening elements stationarily arranged on its circumference for opening a delivered sliver into individual fibers and for combing out the fibers at a comb-out point. The opening roller has a mechanical stripping arrangement that rotates along with it. The stripping arrangement includes ejectors that are pivotably fastened on the opening roller. Each ejector is arranged between the opening elements and extends over the opening roller transversely in relation to the direction of rotation. The ejector strips combed-out fibers off the opening elements and improves the opening of the opening roller as well as the transfer of the fibers from the opening roller. The opening arrangement is advantageously employed with an open-end spinning frame.Type: GrantFiled: August 27, 2002Date of Patent: November 23, 2004Assignee: W. Schlafhorst AG & Co.Inventors: Helmut Feuerlohn, Thomas Weide

Patent number: 6792744Abstract: A spinning device for producing a spun yarn by a circulating air flow in a housing has an adjustment device (17) for controlling the angular position of the fiber ends wrapped around a spindle head, and in turn, the angular position of the fibers wrapped around the produced yarn, by adjusting a linear component of an air flow into the spinning device as a function of the yarn withdrawal speed, whereby a yarn is produced of a required yarn strength even during a spinning start phase in the process of making the spun yarn.Type: GrantFiled: January 16, 2003Date of Patent: September 21, 2004Assignee: W. Schlafhorst AG & Co.Inventors: Helmut Feuerlohn, Thomas Weide

Patent number: 6314714Abstract: A device for producing spun yarn by means of an airflow acting in a twisting manner on the fibers of an untwisted sliver (1) as the sliver is being conducted into and through a spindle assembly (3). The spindle assembly (3) comprises a spindle head portion (5) which conically tapers toward a spindle inlet opening (2) and is rotatable independently of a spindle core portion (7) through which the yarn is withdrawn. The device suppresses any tendency of the yarn strength to decrease at high, increasing numbers of spindle revolutions.Type: GrantFiled: June 19, 2000Date of Patent: November 13, 2001Assignee: W. Schlafhorst AG & Co.Inventors: Helmut Feuerlohn, Liberto Coll-Tortosa, Francesc Roig Munill, Thomas Weide, Jose Antonio Tornero-Garcia, Oliver Schulze

Patent number: 6209304Abstract: A device for producing spun yarn by means of an airflow acting in the area between a sliver guide and a spindle (13) on fibers of a non-twisted sliver (10) drafted and delivered by a drafting arrangement in order to twist the fibers. Thereafter, the sliver (10) is passed through the spindle (13). Outside of an imaginary center line (9) of the traveling sliver (10), the sliver guide is arranged such that the fibers are passed along the inward lying surface of the sliver guide. The sliver guide comprises fiber guide elements (16) spaced apart from each other, which permit the free passage of a core fiber bundle. An improved spinning process, along with high productivity and increased yarn strength is possible by means of the device of the invention. The spinning device can be manufactured and operated cost-effectively.Type: GrantFiled: October 4, 1999Date of Patent: April 3, 2001Assignee: W. Schlafhorst AG & Co.Inventors: Helmut Feuerlohn, Liberto Coll-Tortosa, Frances Roig Munill, Thomas Weide, Jose Antonio Tomero-Garcia, Oliver Schulze

Patent number: 4974718Abstract: A yarn package transferring apparatus having a slide for sliding yarn packages thereon from a yarn processing machine and a vertical endless belt assembly for raising the packages from the bottom of the slide to a conveyor which carries the packages for delivering to a location for further handling. The slide has an apparatus for orienting a predetermined leading or trailing end of the packages entering the slide for sliding thereon and a recess adjacent its lower end for uniformly positioning the packages for receipt by the vertical endless belt. A plurality of inclined platforms regularly spaced along the vertical endless belt translationally carry the packages to a package stripper which removes the supported packages from the platforms and loads the packages onto the conveyor.Type: GrantFiled: October 6, 1988Date of Patent: December 4, 1990Assignee: W. Schlafhorst & Co.Inventors: Hans Raasch, Helmut Feuerlohn

Patent number: 4506497Abstract: A method for metering and injecting small amounts of fluid into the splicing air of a splicing head of a compressed gas thread splicing device including a metering valve having a piston with a metering chamber formed therein, the metering chamber having a given volume determining the amount of fluid to be injected, the piston being slideable between a loading position and an injecting position of the metering chamber, a circulating fluid circuit connected to the piston, and a compressed gas circuit connected from the piston to the splicing head, which includes connecting the metering chamber to the circulating fluid circuit in the loading position before splicing, moving the piston from the loading position to the injecting position, and subsequently bringing the metering chamber in contact with a compressed gas current in the compressed gas circuit flowing into the splicing head as splicing air at the moment the fluid is to be injected for splicing, and a device for carrying out the method.Type: GrantFiled: February 2, 1984Date of Patent: March 26, 1985Assignee: W. Schlafhorst & Co.Inventor: Helmut Feuerlohn
