Patent number: 5715584Abstract: Multiple (at least two) differently colored or colorable feed yarns are fed from their respective yarn packages to a multi-position interlacer manifold assembly. The feed yarns are maintained separate and apart from one another and are passed in this separated state through individual interlacer jets associated with the interlacer manifold assembly. The individual yarns are thereafter conveyed to a conventional yarn processing system (e.g., an apparatus known colloquially in the art as a "Gilbos" apparatus) where they are entangled with one another to provide a finished yarn in which the individual yarn components remain substantially coherent throughout the finished yarn. The individual interlaced yarns thus become entangled with one another when subjected to the yarn processing system without substantial inter-yarn blending or commingling occurring (which blending or commingling would thereby cause the constituent yarns to become nearly indistinguishable from one another).Type: GrantFiled: March 25, 1996Date of Patent: February 10, 1998Assignee: BASF CorporationInventors: Andrew M.

Patent number: 5425227Abstract: In a textile-processing operation wherein a filament is displaced longitudinally continuously past a treatment station and a liquid is applied to the moving filament at the station, a supply of the liquid is held in a container spaced from the station and connected via a conduit to an applicator at the station. Space above the liquid in the container is filled with a gas that is devoid of free oxygen and that is in direct contact with the liquid. This gas above the liquid is pressurized in the container to controlledly force the liquid from the container through the conduit to the applicator at the station. The liquid is kept out of contact with oxygen until it actually has been applied to the filament. In fact the filament is passed over a small-diameter orifice formed in a guide and the liquid is forced from the orifice. The filament directly engages the guide at the orifice and covers the orifice so that the liquid does not contact the ambient air until after it is applied to the filament.Type: GrantFiled: March 23, 1993Date of Patent: June 20, 1995Assignee: Zinser Textilmaschinen GmbHInventor: Gunter Konig

Patent number: 4644620Abstract: Apparatus for the effective manufacturing of bulk yarn employing fluid and comprising two assembled blocks of simple geometric form. The apparatus is characterized by a yarn path part having a polygonal cross section which is defined by planes arranged in the yarn-travelling direction. A part of the yarn path part, however, is provided with a fluid-jetting opening and is constructed with a different cross-section. That part, the yarn-treating section, is defined by curved faces and planes having a cross-section larger than that of the polygonal cross-section of the yarn path part. The bottom part of the yarn treating section has a curved face with said fluid-jetting opening therein, a separate covering part encloses the yarn path part to tunnel-like member.Type: GrantFiled: June 14, 1985Date of Patent: February 24, 1987Assignee: Murata Kikai Kabushiki KaishaInventor: Yoshiyasu Maeda

Patent number: 4615167Abstract: A method and apparatus for forming a yarn or sewing thread from core and effect yarns. The effect yarn is drawn at no higher than a normal drawing ratio for material from which the effect yarn is made and the effect yarn is softened by sufficient heating, in order to prevent rupturing of the effect yarn during drawing. The core or effect yarn is passed through a wetting device to aid aspiration and entanglement of the core and effect yarns in a fluid jet device. The effect yarn is overfed to the jet device to aid in the formation of a highly entangled looped yarn which is subsequently set by a heated roller while contraction of the yarn is prevented. The core yarn can also be drawn at or below its normal drawing ratio in order to aid in developing thread tenacity and ensure an acceptable elongation at break after dyeing or subsequent wet processing.Type: GrantFiled: June 25, 1985Date of Patent: October 7, 1986Inventor: Neville G.
