Definitions

  • the present invention relates to a device for piling-up such a weft thread cut to the right length for a loom, which device comprises a hollow body into which hollow body the weft thread is blown through a thread inlet opening and from which body it protrudes with one end of the thread after the same has been blown in, a second opening issuing into the cavity of this hollow body, the orifice of which lies in the region where the blown-in air fiow carries along the thread.
  • the present invention has the new object, of providing a device of the kind referred to, with the use of a hollow body open at both ends in such a manner that the weft thread previously cut off at a length is blown in at the front end and is seized at the opposite i.e. the rear end, at the latest before its entry into the shed.
  • the end of the weft thread is to be seized before its passing through the shed, is accordingly that one which lies at the tip of the blown-in weftth-read.
  • a device on looms for piling-up a weft thread pre-cut to a predetermined length preparatory to its insertion into the warp shed of a loom comprising a movable hollow body having an interior piling-up space for passing through said warp shed, said hollow body having an inlet opening and an outlet opening, said interior piling-up space lying between said inlet opening and said outlet opening so that the loading end of said weft thread emerging from said interior piling-up space can pass through said outlet opening, blowing-in means for said weft thread adjacent said inlet opening for blowing said weft thread through said inlet opening into said interior piling-up space and for carrying along said weft thread towards said outlet opening and for blowing said leading end into said outlet opening, said hollow body having guiding means guiding said end of said Weft thread into said outlet opening, slowing-down means arranged outside of said interior piling-up space for acting
  • said hollow body has additional openings positioned outside the direction of the airflow which in operation blows said weft thread into said hollow body and affording said airflow an additional escape thereby assisting the slowing-down of said leading of said weft thread by said slowing-down means.
  • FIGS. 1, 2 and 3 show a first embodiment, namely:
  • FIG. 1 the beginning of blowing-in
  • FIG. 2 the beginning of the formation of a pile-up
  • FIG. 3 the finally blown-in weft thread

  • FIG. 10 an elevation of the seventh embodiment in section on the line X-X of FIG. 9.
  • FIG. 2 illustrates the operation of blowing-in at an advanced stage: the end 1 of the thread, by contining to fly in the direction of blowing, has already reached an abutment in the form of an oblique plate 6, the portion 10 serving as a guide for threading the end 1 of the thread through the opening 5, in case the end 1 of the thread should have slightly deflected from the direction of blown 3 v 7 ing when being .blowndn. Sincethe thread has been slowed down'onthe face 6, the rear portion 7 of the thread begins to form loops which do not pass through the opening 5.
  • I 1 illustrates the operation of blowing-in at an advanced stage: the end 1 of the thread, by contining to fly in the direction of blowing, has already reached an abutment in the form of an oblique plate 6, the portion 10 serving as a guide for threading the end 1 of the thread through the opening 5, in case the end 1 of the thread should have slightly deflected from the direction of blown 3 v 7 ing when being
  • FIG. 3 shows, still for the first embodiment, the final phase of the blowing-in.
  • the entire length of the weft thread has emerged from the nozzle 2, and has formed in the hollow body 3 a pile-up 8, which at least-partly obturates the outlet opening 5, through which the end 1 protrudes, which has been slightlyadefiected by the oblique face 6.
  • the latter is provided with a series of holes 9 lying outside the main direction of the air flow and acting like a sieve. These openings 9 form at the same time an additional slowing-downmeansassisb ing the abutment proper, namely the oblique face jin its slowing-down effect. "The reason for this is that through the outlet opening 5 during the blowing-in, i.e.v
