摘要： The weaving machine with a weft monitoring insertion system (1) for a large number of different weft threads (11, 11', 11") comprises a weft insertion member (6, 60), thread brakes (3), a weft thread selector (4) for the serving of a thread (11, 11', 11") or of more than one thread at the same time, a thread monitor (51) for weft threads (11) which are correctly inserted, and an electronic and programmable control member (8) for the setting of the thread brakes. The weft threads (11), when correctly inserted, form incoming angles (.alpha.) at the thread monitor in the presence of a deflection which depend on the choice of the weft thread. Utilizing the thread monitor (51) a signal can be produced for the control member (8) which is dependent on the incoming angle and the thread tension. Control signals can be calculated and produced in the control member as a result of this signal and as a result of information on the current serving of the weft thread or of the weft threads, i.e. of the presentation of the threads to be inserted through the weft thread selector (4).

摘要： A weft yarn feeding device includes a feed roller which rotates at a circumferential speed equal to a running speed of a weft and a pinch roller which moves in and out of contact with the circumference of the feed roller with the weft in between. The rollers are provided between a length measuring device and a main nozzle for injecting a fluid. Upon commencement of feeding of the weft, the feed roller and the pinch roller are brought into mutual pressure contact to positively feed the weft toward the main nozzle. Further, the feed roller surface has a large frictional coefficient and the pinch roller surface has a very small frictional coefficient.

摘要： A weft feeder in which a variable-diameter drum receives from a windmilling arm multiple turns of thread that form a weft reserve, and in which a variable-diameter swift is associated with the drum to transport the turns from the base of the drum to its head; the swift is formed by multiple rods which protrude in a cyclic manner from corresponding slots of the drum; the extent of the protrusion of the rods from the slots determines the mutual distance between the turns of the thread reserve. The swift and the drum are formed by corresponding sectors that are radially movable and are controlled by respective radial shifting mechanisms, each of which comprises at least one actuation gear that meshes with individual gears for shifting the respective drum and swift sectors. The pair of actuation gears is turned by a single transmission element which is controlled by an actuation knob that is also used to vary the extent of the protrusion of the rods.

摘要： An apparatus and method for correcting an irregularity during the insertion of a weft yarn into a weaving rotor of a series shed weaving machine involves drawing a length of weft yarn from a supply unit and delivering the weft yarn to the weaving machine in synchronicity with the weaving cycle. The length of weft yarn is inserted into a weft yarn conveyor apparatus and wound around a conveyor roller. A sensor is positioned between the supply unit and the conveyor apparatus to detect a weft yarn interruption, e.g., as a result of a weft yarn breakage or the yarn running out of spool. When the interruption is detected, the conveyor roller continues to deliver weft yarn stored in the storage apparatus until a complete weft yarn insertion into the weaving machine has taken place (i.e., weft yarn having a single loom width). The weft yarn is then cut at the insertion side of the weaving machine and the weaving machine is stopped. The weft yarn remaining in the weft preparation unit is then pulled back by the conveyor roller and discharged into a waste container.

摘要： Device for positive modulated braking of weft feeder thread, including a braking body, typically a frustum-shaped braking body, that is supported frontally and coaxially to the drum of the feeder in order to directly or indirectly engage the thread that unwinds from the drum. The braking body is subjected to the action of an electromechanical actuator, supplied by an excitation current that is modulated so as to match the variation in the mechanical tension of the thread during the weaving process; the braking body is rigidly coupled to a support that is movable in the axial direction of the drum of the feeder and is supported and guided by a fixed support. The movable support is subjected to the action of a reversible motor that is supported by the fixed support, is supplied with the modulated excitation current, and is connected to the movable support with the interposition of a mechanical coupling capable of converting the angular movements of the shaft of the motor into corresponding translatory motions of the movable support with respect to the fixed support.

摘要： A weft feeder for gripper or projectile looms allows an operator promptly to restore the continuity of a weft yarn from a yarn feed spool to members for weft insertion into a loom shed, in case of weft yarn breakage or interruption. Downstream of a first yarn guide outlet, there are mounted a double-leaf brake, a separating element, and a second downstream yarn guide eyelet. The separating element is controlled by an actuator so as to separate two brake leaves of the double-leaf brake and to form a duct to guide the weft yarn from the first eyelet to the second eyelet.
