摘要： A fibre band or sliver is passed through a defined opening of a measuring station. Said opening has a cross section smaller than the diameter of the fibre band, so that the band contacts the walls of said opening which thereby defines a measuring cross section. The fibre band while passing said opening is transilluminated by at least one light source. The transmitted light intensity is measured by a light receiver and is detected as a measure for the quantity of the fibre material present in said cross section.

摘要： In order to monitor the correct receiving of an inserted weft yarn by a gripper in a receiving unit of a shuttleless weaving loom a detector is provided which is stationary mounted on the receiving side in an interspace between said gripper and a slay bar or reed of said weaving loom. Said detector comprises a plate-member projecting into said interspace or gap and having an inclined flank which is contacted by the weft yarn on his path between the inserting position and the beaten-up position. The passing of the weft yarn over this flank is detected by measuring potential variations in the detector during a defined phase of the machine cycle.

摘要： A spindle shaft is flexurally elastic at its shank part mounted in a bearing sleeve. The spindle shaft carries a belt-engaging wharve which is arranged underneath the neck bearing and to which a drive belt engages to rotate the spindle shaft. The bearing sleeve is arranged to have radial play within a spindle housing 10. The bearing sleeve is fastened at its lower end via a flexurally elastic tilting joint 40 to the spindle housing 10 connected rigidly to the spindle rail. The pulling force of the drive belt engaged to the wharve during operation deflects the bearing sleeve radially by tilting it about the tilting joint. Such deflection brings about, on the other hand, a pivoting of the bobbin-carrying upper part of the spindle shaft about the neck bearing in the opposite direction as a result of the bending moment occurring on the shank part, an inclination of the spindle shaft with its upper part is thus avoided.

摘要： For the detection of the presence of contaminants in yarn a first optical sensor is used to measure the amount of light reflected from the yarn. The signal from this sensor not only depends on the presence of contaminants but also on the diameter of the yarn. For eliminating the dependence on the yarn's diameter, a second signal is recorded, which depends essentially only on the yarn's diameter. By appropriate combination of these two signals in a microprocessor system the influence of the yarn's diameter in the first signal can be eliminated.

摘要： The thread braking device comprises a pair of braking members, which are arranged symmetrically in respect to the path of the thread. Each of the braking members has a spring member. Between these spring members a line-shaped, vertically arranged braking zone is defined. For braking, the spring members are pivoted on rockers towards the thread path. Due to this movement as well as due to the vertical arrangement of the spring members, the deposition of contaminations in the braking zone is avoided. The elasticity of the spring members reduces the danger of damage in the presence of thickened thread sections.
