  • Patent number: 11702771
    Abstract: This shedding mechanism includes a housing and a movable hook which can be retained by a selection device including at least one electromagnet (100) immobilized in the housing and which includes a ferromagnetic core (102) comprising first and second pole faces (S122, S124). The electromagnet (100) also includes a non-magnetic portion (104, 108) and a retaining lever configured to retain the movable hook. The retaining lever is pivotally mounted about an oscillation axis (A144) and includes a ferromagnetic armature (202) that interacts magnetically with the first and second pole faces. The non-magnetic portion of the electromagnet includes a surface (S144) for guiding the pivoting of the retaining lever. This guide surface cooperates with the retaining lever in a direction radial to the oscillation axis (A144) between a remote position and a contact position. The guide surface (S144) is cylindrical with a circular base, centered on the oscillation axis.

  • Patent number: 10085424
    Abstract: A retractable leash and collar/harness assembly. The assembly includes a hub that contains a spring member and leash line coiled and enclosed within the hub. The spring member and leash line remain in constant communication with each other. The hub contains an aperture through which the leash line can flow. Extending outwardly from the hub are snap buckles, one of which is structured to have a channel formed therein. The leash line can flow through the channel to a handle, which is contained within a pouch formed on the attached collar. When the leash is pulled, the handle separates from the pouch, followed by the leash line. Thus, when in use, the leash line follows a path of travel from the hub, through the snap buckle, through the pouch and into the external environment. In an alternative embodiment, the current invention may be a leash and harness assembly.

  • Patent number: 8381773
    Abstract: Disclosed is a thread feeding method (the method) for feeding threads to a weaver. The method includes a step of feeding a multiplicity of strands of yarns with intervals to each line of the thread feed lines, while some strands of the multiplicity of strands of yarns are being separated from the other strands according to color or shade to be expressed at spots where they are either woven or knitted and are then fed to the weaver such that the colors or shades of the separated strands are combined to express target colors or shades at the spots where the strands are woven or knitted. The method of the present invention allows changing of colors or black and white shades of the threads being fed to the weaver. The method also allows the strands to be combined with other strands of yarns with different colors to express tens or hundreds of colors on a fabric.

    Abstract: Each lifter (2) has a displacement member (4) which can be connected to at least one directable thread (18) and which has two spring arms (28a, 28b) that can be coupled to lifter blades (34a, 34b) which move up and down. The lifter blades are not attached to the spring arms (28a, 28b) in the starting position of the latter. In the lower shed position (T), the spring arms (28a, 28b) can be displaced into position for coupling with the lifter blades (34a, 34b) using an actuator (40). The displacement member (4) can be locked in the upper shed position using the same actuator (40). To improve the jacquard machine, the switching member (38) is positioned at the end of a spring tongue (44) that is aligned in the direction of displacement and is fixed to the displacement member (4, 4a) outside the spring arms (28a, 28b). The actuator (40, 40a) is located laterally outside the spring arms (28a, 28b) in such a way that it acts transversely in relation to the latter.

  • Patent number: 6880582
    Abstract: A first (1) and a second connecting means (2) which may be connected in a detachable manner in order to connect a first and a second cord, more particularly a lifting cord and a harness cord of a Jacquard machine, the first connecting means (1) comprising an elastically deformable coupling element (3) which may be received in a receiving part (4) of the second connecting means and may be retained in axial direction, the second connecting means (2) comprising a passage (5) through which the coupling element (3), compressed in the radial direction, may be moved to the receiving part (4) and the coupling element (3) in the receiving part (4) having the possibility of adopting a larger radial dimension than is necessary to be moved through the passage (5), so that the coupling element (3) snap-fits in the receiving part (4). In the receiving part (4), the coupling element (3), by rotation around the longitudinal axis (A), may be brought into a disengaging position in which it is not retained.

  • Patent number: 6834681
    Abstract: In a loom with a mechanical weft insertion the motion of each individual warp thread on its way from an uppermost position to a lowermost position and vice verse is controlled individually by a jacquard in such a way, that the motion profile includes a shed stopping in a weft entrance section and simultaneously in a weft exit section of a weaving width of the loom. Shed stopping is avoided in an intermediate section between the weft entrance and exit sections of the weaving width of a loom thereby providing sufficient time for the rapiers or grippers to be withdrawn from the shed without damaging the warp threads.

  • Publication number: 20040168735
    Abstract: A shedding device in a jacquard loom, for forming the lower shed, for instance, has a retracting spring which is rigidly anchored on one end in the loom or to the floor. To suppress the development of resonance in the spring, a core element is provided, which contacts the inside of the spring at points spaced apart from one another and forces the spring to take a course which deviates from the rectilinear. As a result, friction forces that contribute to damping the spring motion are created between the spring and the core element.

  • Patent number: 6494237
    Abstract: The invention relates to a shed forming device without a harness for the textile industry, preferably a weaving device which contains a number of healds (4) with thread eyelets (5) for guiding the warp threads. The healds (4) are guided through boreholes (31, 31′) of guide elements (20, 6). Said healds (4) are positioned in such a way, that at least one of the guide elements (6) is configured as a lifting element of a lift generating device, in order to perform a vertical ascending and descending movement. An optional connection between the guide element (6) and the heald (4) can be made and electrically controlled by catch devices in the horeholes (31, 31′), in such a way, that the heald can be caught by the lifting movement. A shed of warp threads can thus be formed which conforms to a pattern.

  • Patent number: 6357486
    Abstract: In a weaving loom of the Jacquard type comprising electrical actuators for displacing heddles controlling the position of the warp yarns, the following steps are carried out: a so-called “normal effort” is determined, exerted by at least one actuator on at least one harness cord in order to displace, between two positions of its normal stroke, at least one heddle connected to a normally taut warp yam; from this normal effort, at least one threshold value representative of a limit of a range of values of normal weaving effort is determined; while the loom is in operation, a so-called “operational effort” exerted by this actuator on the harness cord is determined; at least one value representative of this operational effort is compared with the threshold value, and a first, so-called “anomaly signal” is generated when the value representative of the operational effort is outside the afore-mentioned range.
