Definitions

  • the bell-shaped trumpets normally have a fixed size opening for the particular desired yarn and therefore, tends to break the roving when there is a slub, trash, etc., in the roving which will not pass through the trumpet opening. If it does not break it will partially stop up which will put stretch in the roving and this causes uneven yarn.
  • FIG. 1 is a schematic side elevation view of the principal elements of a spinning frame
  • FIG. 2 is a front view of the new and improved trumpet taken on line 2-2 of FIG. 1.
  • FIG. 1 there is shown, diagrammatically, the essential elements of a spinning frame with which a trumpet constructed in accordance with the invention is particularly useful.
  • a creel includes a frame or support 14 from which a number of rolls or packages of roving depend, such as package 12 of roving rotatably suspended from the frame 14. From the package 12 the roving 11 is led over a roving bar 16 and thence downwardly through the trumpet 18 which is mounted on a transverse bar 20 disposed behind the drafting rolls. Customarily. three pairs of drafting rolls are employed, a pair of back rolls 22, a pair of middle rolls 24, and a pair of front rolls 26.
  • the middle rolls 24 rotate faster than the back rolls 22, and the front rolls 26 rotate faster than the middle rolls 24; hence the fibers of the roving are drafted.
  • the roving 11 after leaving the trumpet l8, proceeds through the drafting rolls along parallel paths until it leaves the bite of the front rolls 26. Then it enters the twisting system, indicated generally at 30, and then is twisted in customary fashion and wound on the spindle of the twisting system.
  • FIG. 2' shows the trumpet 18 in greater detail to illustrate the principles of the invention.
  • the trumpet 18 is generally triangular in shape with an indented portion 32 to accommodate a bolt 34 which secures the trumpet to the traverse bar 20.
  • the roving 11 runs through the upper portion 36 of the trumpet but will move down in a lower position if a slub, lint, etc., is encountered by the trumpet.
  • the trumpet is designed to allow the roving to seek its own position in accordance with the size of the roving and to this end the sides 38 and 40 of the trumpet diverge outwardly in the down direction to provide the triangular shaped trumpet shown.
  • the trumpet is substantially flat and is molded from a friction resistant plastic like material to provide a substantially frictionless surface for the roving to run over.
  • a roving guide for a spinning frame comprising: a generally triangular shaped flat body member molded from a friction resistant plastic like material having an opening therethrough, said opening being formed by two side walls which diverge from the apex of said body member and a third wall interconnecting said diverging walls and having a portion thereof bowing upwardly toward the apex of said body member.
