Definitions

  • This invention relates to the art of making thread or yarn from fibres of cotton, wool, plastics including rayon, nylon and mixtures of two or more of such fibres, and is particularly concerned with a new method and new means for preventing the accumulation of short fibres on the spinning frame parts, i. e. cleaning and maintaining clean said parts.
  • the preparation of fibres for spinning consists generally of cleaning and blanding the fibres and then drawing them out through many operations so that the individual fibres tend to become parallel and to form endless, slightly twisted rope-like strands generally known as roving.
  • This roving is drawn through the drafting rolls of the spinning frames and there is twisted and spun at high velocity.
  • fly or lint the short broken fibres and any insecurely retained longer flbres, known as fly or lint, tend to be thrown out to float in the air and settle on various parts of the spinning machines, particularly within the underframes thereof.
  • fly accumulations are a serious problem because their removal is expensive and results in a certain substantial amount of fly winding up in the yarn as gouts and slubs which cause weakness, breakage and loss of yarn product, while failure to remove such accumulations involves the hazard of destructive flash fires.
  • Air streams could theoretically be used to efl'ect the desired cleaning but the problem of generating such streams and delivering them against all the parts in the underframe to be cleaned has apparently been insoluble.
  • a continuous strong blast of air is far too expensive to use in this way, the quantity of air and the pressure required being enormous because of the dimensions of the ordinary spinning machine.
  • a traveling air stream could not be applied effectively from outside the frame and severe space limitations within the frame made any known traveling air stream generating and/or directing means entirely impracticable.
  • the present invention provides a method and apparatus which are quite effective in keeping the underframe and its parts substantially free from material accumulations of lint, which is accommodated within the limited space confines of the underframe without any substantial alterations in the construction thereof, which can be readily installed in already constructed spinning machines and even more readily incorporated in new machines and which makes it unnecessary to shut down the spinning machine for underframe cleaning.
  • the invention may'serve to clean not only the underframe but also the creels, thereby making unnecessary the use of the overhead cleaner of the aforesaid patent.
  • the present invention is based on the principle of directing air outwardly from within the underi'rame of a spinning machine automatically, repeatedly, at short intervals and at considerable velocity against substantially all the working parts thereof successively or in any other predetermined order.
  • this invention provides a continuous, axially short stream of air which rotates about an axis extending longitudinally of the underframe and reciprocates between the ends of the machine, thereby tracing a spiral path while moving toward one end of the machin and a difi'erent spiral path when returning to the other end of the machine.
  • This stream keeps the underframe parts substantially free from "fly and, when the frame is open at the top, also keeps the creels free from fly.
  • the traveling stream of air of this invention not only prevents accumulation of lint as aforesaid, but rolls the lint over and over on the floor so that it is brought into a relatively compact condition in which it can be readily removed by brooms or other means.
  • air under pressure is supplied to a rotating tube extending lengthwise of, and within, the underframe and this air is discharged through successive, longitudinally short portions or this tube.
  • the rotation of the air stream directing means and of the air stream themselves may, in accordance with this invention, either be continuous or intermittent, the important and controlling factor being the frequency with which such streams are delivered againstaa given surface to be cleaned.
  • a series of radially spaced streams may be defined for the same results, as by tiirning the streams in a series of steps through a number of small angles around an axis extending generally longitudinally of a spinning machine frame.
