摘要： Method of controlling a plurality of relay nozzles (RNx) is a jet weaving machine. These nozzles are consecutively actuated for supporting the insertion of the weft yarn (WY) into the shed of the weaving machine and up to the arrival end (AE) of said shed by means of consecutively opening solenoid valve associated with nozzles. The valves are controlled on the basis of calculated information representing the momentary real position of the weft yarn (WY) during it path in the shed. The invention also relates to an apparatus for carrying out said method.

摘要： A pulley with a variable working diameter, including two coaxial disks which are rotatable relative to one another, of which the one has a radial and the other at least one spiral-shaped guide groove. A plurality of support members with a segmentlike form are positioned between the disks and can be clamped with their front sides between the disks in different radial positions so that their radially outer peripheral areas define a polygonal path which is similar to a circle. The support members having projections engaged in the guide grooves of both disks so that relative rotation of the disks moves the support members radially for changing the respective circle diameter. Each support member--viewed in the direction of the axis of rotation of the disks--has the shape of an asymmetrical segment, preferably a circular-ring segment, with a longer and a shorter diagonal. An extension of the longer diagonal is spaced from but passes by on the same side of the axis of rotation of the disks as a perpendicular to a tangent on the spiral-shaped guide groove in the area of the support member.

摘要： A rotatable shaft carries a winding instrumentality whereby thread to be temporarily stored is coiled around a thread drum rotatably mounted on the shaft. Rotation of the thread drum in the direction of shaft rotation is prevented by concentric relatively fixed and movable brake elements, the fixed one secured to housing for the apparatus, the movable one coaxially secured to the thread drum. One of the brake elements has a circumferential surface from which elongated resilient fingers project, the fingers being more or less radial to said surface and having their tips normally engaged under flexing bias against a circumferential braking surface on the other brake element. The thread passes through the zone of the fingers, and the several fingers are so inclined to radials from the common center of the brake elements that the thread, or a guide tube through which it extends, can flexingly cam each finger, in turn, out of engagement with the braking surface and pass around the finger.

摘要： A device for feeding weft yarns to a weaving machine which includes a rotatingly driven retainer that is constructed such that it has little mass. The retainer is coupled to a rotary drive unit such that the retainer cannot move radially with respect to a storage drum axis so that, when viewed in the direction of circulation of the withdrawal point, the retainer continuously extends through a circulatory path ahead of the weft yarn. The rotary drive unit is additionally connected to a control device which controls the acceleration and deceleration of the retainer in accord with a speed profile and determines the process of weft insertion in the weaving machine.

摘要： In a method for controlling a yarn storage and feeding device, particularly for a mechanical loom, comprising a storage surface adapted to have windings of a yarn wound thereonto and withdrawn therefrom by a consumer, and a control unit for a winding drive mechanism operable to adjust the winding speed in accordance with the consumption rate and in response at least to the actual value of the number of yarn windings on the storage surface, for adjusting the actual value towards a predetermined desired value, the desired value is altered in response to at least one alteration of the winding speed to thereby obtain an optimum smallness of the yarn supply on the storage surface. In a yarn storage and feeding device for performing this method, the control unit cooperates with a reference value memory (18) for the supply of desired values (nV) varying in a predetermined manner.

摘要： According to a method and apparatus for controlling the insertion process of a weft yarn, the weft yarn is temporarily exposed to a braking friction and the yarn tension is mechanically picked-up. In order to prevent the friction from having a disturbing or damaging effect on the yarn, the yarn tension is only temporarily picked-up during certain phases of the insertion process, in order to derive information from the tension curve that is useful for the control of the insertion process. In a power loom, in particular a jet, rapier or gripper shuttle loom, a tension sensor for sensing the tension of the weft yarn can be switched during insertion between its sensing position and a passive position in which it does not touch the weft yarn. Preferably, the tension sensor is integrated in the insertion brake or even forms the braking element itself.
