Definitions

  • This invention relates to textile machinery, and particularly to drawing mechanisms for spinning machines and the like.
  • this invention is concerned with improvements in the type of drawing mechanism which employs two sets of cooperating rollers.
  • One set hereinafter referred to as bottom rollers, is mounted on the machine frame for rotation about substantially fixed axes.
  • the other set of rollers is referred to as top rollers without necessarily implying that the top rollers are mounted above the bottom rollers.
  • the top rollers are mounted on a common carrier arm pivoted to the machine frame.
  • a sliver of fibrous material or the like is drawn by passage between the cooperating rollers of the two sets.
  • the general path of the sliver between the rollers will be referred to hereinafter as the drawing area.
  • the operating characteristics of the drawing mechanism under otherwise similar conditions are determined by the pressure exerted by the rollers on the passing sliver. Since the axes of the bottom rollers are usually fixed, this pressure is generated by movement of the top rollers toward the drawing area.
  • top rollers namely a drawing-in roller, a middle roller, and a front roller arranged in this sequence along the path of the fibrous material
  • the invention is not limited to apparatus having any specific number of rollers, but is useful in any drawing arrangement in which the number of top rollers sequentially engaging the sliver is greater than one.
  • twin rollers integrally joined by a common shaft, and the term roller as used hereinafter will be understood to cover a single roller as well as a plurality of rollers fixedly connected for rotation about a common axis.
  • the object of the invention is the provisionof a drawing mechanism in which the pressure exerted by at least one of the several sequentially arranged top rollers on the sliver being drawn may be adjusted substantially without altering the pressure of the other rollers.
  • a more specific object is the provision of means for altering the pressure of individual top rollers while the mechanism is operating.
  • the invention in one of its aspects interposesyieldably resilient pressure means between the carrier arm of the mechanism and one top roller which is movably mounted on the arm.
  • a pressure fluid actuated motor on the machine frame acts on motion transmitting means associated with the carrier arm to move another top roller also mounted on the arm toward the drawing area under the pressure of the fluid.
  • FIG. 1 is a schematic fragmentary sectioned elevation Patented Sept. 14, 1965 of a spinning machine equipped with a drawing mechanism of the invention
  • FIG. 2 illustrates another drawing mechanism of the invention in an elevationally sectional view
  • FIG. 3 shows a portion of the device of FIG. 2 in the inoperative position thereof
  • FIG. 4 is a fragmentary elevational section of the apparatus of FIG. 2 taken on the line IV-IV;
  • FIG. 5 shows a modification of the apparatus of FIG. 2 in a corresponding detail view
