摘要： A picking channel for pneumatic jet looms with auxiliary blowing sections disposed across the weaving width and consisting of at least three auxiliary blowing nozzles the relative positions of the axes of which being those of skew lines with the axis of the first auxiliary blowing nozzle crossing the axis of the weft thread under insertion. The axes of the other auxiliary blowing nozzles pass said axis of the weft thread under insertion of the outside, in the direction of the axis of the first auxiliary blowing nozzle. The various dispositions of both the auxiliary blowing sections and nozzles insure reliable weft insertion, and economic exploitation of the energy of the carrier medium and, consequently, a greater weaving width.

摘要： Weft beat-up mechanism for a loom. A reed for beating-up the weft toward the binding point at the front end of the fabric is mounted on a driven active member on the loom. The active member is pivotally mounted on the loom and its drive is coupled with the loom drive. The reed is mounted in a carrier which is mounted for limited swinging with respect to the active member, with the pivotal axis thereof parallel to the axis of the beat-up weft. The reed is constantly resiliently thrust by a power element, such as a coil compression spring, relative to the active member in a direction toward the binding point of the fabric. The mechanism of the invention increases the security of setting of the inserted weft, and reduces impact forces between the reed and the binding point of the fabric during the weaving process.

摘要： The present invention relates to an apparatus for accurately controlling the distribution of pressure fluid through a number of branch conduits, the apparatus being advantageously employed for jet looms. The apparatus eliminates excessive wear of mutually engaged parts which would otherwise cause unwanted time delays in the operative steps of the system with which it is employed. The apparatus includes a plurality of valves, each valve having a movable valve element coupled with the outer race of an anti-friction bearing mounted on an eccentric by means of a piston and a push rod provided with a spring which maintains the piston in engagement with the outer race. The valve is opened when a stop on the piston is moved by the eccentrics into engagement with the other end of a push rod which forms a part of the movable valve element.
