摘要： A weft inserting device using a profiled reed for an air jet loom is equipped with a plurality of reed pieces each having a C-shaped guide notch. The line of guide notches forms a weft passage where weft injected from a main nozzle flies. Each guide notch has a upper wall parallel to the floor surface on which the device is placed, a deep wall perpendicular to this surface, a lower wall which gradually becomes wider toward an opening, an upper connecting portion which connects the upper wall to the deep wall, and a lower connecting portion which connects the deep wall to the lower wall. The radius of curvature of the upper connecting portion is set equal to or smaller than 1 mm, and the radius of curvature of the lower connecting portion is set greater than the radius of curvature of the upper connecting portion.

摘要： A take-up rate and a let-off rate in warp feed on a loom are controlled while a displacement (.DELTA.L) of a cloth fell position C is taken into account. The system comprises a cloth fell position compensation circuit (2, 16, 21) which outputs a cloth fell compensation signal (.DELTA..omega..sub.c) to compenate a displacement (.DELTA.L) of the cloth fell position (C) when a weaving condition such as a target weft density (D*), a target warp tension (T*) or the kinds of weft and warp yarns is changed. The cloth fell compensation signal is added to a basic warp feed rate (.omega..sub.f) obtained from D*, so that the displacement motion of the cloth fell is completed in a shorter time. According to this compensation, a weft density of a resultant fabric rapidly coincides with the target weft density.

摘要： An apparatus for measuring the weft yarn length for a loom constructed in accordance with the present invention comprises at least two weft yarn supply units each having a weft yarn length measurement element presenting a yarn winding surface, an equal number of electric motors each adapted for winding weft yarn around said yarn winding surface of the measurement element, and weft yarn latching mechanisms for controlling the amount of the weft yarn wound on each winding surface and the transfer of the wound yarn in the weft inserting direction. Each of the rotational speeds of the respective motors and the operation of the respective weft yarn latching mechanisms may be controlled by a control unit in accordance with a preset weft yarn selection program.Each yarn length measurement element may be associated with a sensor for sensing the number of times the weft yarn is wound on the element. Sensor signals are introduced into the control means from said sensors and speed commands are outputted from said control means to respective motors for compensating for any fluctuations that may be caused in the measured lengths of the weft yarn.

摘要： A dust removing mechanism is applied to each unit of an open-end spinning machine. In each spinning unit provided with an opening roller and a spinning rotor for creating a yarn from fibers supplied from the opening roller, a casing partly surrounds the opening roller and a dust removing opening is formed in the casing. In such mechanism, a dust removing zone is formed so that it communicates with the dust removing opening and the dust removing zone is divided into a dust separating zone and a dust discharging zone. An air-takein opening is provided so as to create an auxiliary air stream, by which the separation of dust from the useful fibers can be effectively carried out.

摘要： A spinning unit for an open end spinning machine is disclosed. The unit includes a rotor having a short cylindrical portion defining a central aperture, a frustoconical portion connected at one end to and converging toward the cylindrical portion, and a portion connected to the other end of the frustoconical portion with air discharge openings. The unit further includes a casing having a first portion, and a second portion connected to the first portion of the casing and surrounding the portion of the rotor connected to the other end of the frustoconical portion to define an annular chamber into which air is discharged through the air discharge openings during rotation of the rotor. The first portion has an inner surface substantially surrounding both the cylindrical and frustoconical portions of the rotor in spaced relationship therewith thereby to provide a relatively long and narrow bent passage defined between the first portion of the casing and the cylindrical and frustoconical portions of the rotor and extending between the central aperture of the rotor and the chamber of the casing.
