Definitions

  • This invention relates to drawing mechanism for spinning and like frames and consists of an improvement in or modification of the mechanism forming the subject of U. S. 5 application Ser. No. 186,425.
  • Such drawing mechanism is characterized by a large diameter 0f the bottom middle roller in comparison to the front and rear bottom rollers and by the elevated position of the middle roller relatively to these two rollers.
  • the middle roller thus has an especially important function in the drawing operation.
  • Forms of drawing mechanism are known, of the three or four roller type, wherein one or a plurality of pressure rollers are also employed, which for the better holding of the roving fibres or for the better driving of the pressure rollers by the bottom rollers are either covered with leather or fluted or provided over their whole surface with ribs or corrugations of other suitable form.
  • the special method of producing the surface of these pressure rollers serves solely for increasing the adhesion of the pressure rollers on their support, whether such support be the tuft of fibres of the roving or the bottom roller itself.
  • the cleaning of the draft rollers is effected fully and entirely by a special formation of the rear pressure roller resting on the middle roller.
  • This heavy pressure roller is provided on its surface, at the places which are not touched by the roving fibres moved to and fro in the spinning, with a special fiuting or grooving which lies either parallel or inclined to the axis of the roller.
  • This fluting or grooving can be produced in various ways, viz. it may be in the form of latched-teeth, facets or 10 fish-scales.
  • the ribs, teeth or the like must however lie in the surface of the pressure rollers and should not project beyond the smooth surface for receiving the roving.
  • Figure 1 shows in front elevation the rollers in question of the drawing mechanism.
  • Figure 2 is a side elevation thereof.
  • the cleaning device operates as follows:
  • the dust which collects on the bottom roller M, is carried along by the ribs or fluting of the pressure roller C or is forced laterally along the smooth running surface or towards the ends of the pressure roller.
  • the clearer roller P bearing thereon takes up the dust from the smooth surface or the dust collects at the ends of the pressure roller at the sides of the ribbed or fluted surfaces of the bottom middle roller M beneath the bear- I V v 1,834,878
  • the portions of the middle ro'ller carry ing the greatest accumulationoi fly, and a' 5 plush covered clearer roller bearing on the top-of; and frictionallyv driven by-the pressure roller the dustbeing conveyed from the amiddle moller and delivered to the clearer roller bylthe flutings of the pressure roller.
