H. FEND ETAL DEVICE FOR PILINGUP A WEFT-THREAD FOR LOOMS Filed July 2, 1962 Jul 20, 1965 2 Sheets-Sheet July 20, 1965 H. FEND ETAL DEVICE FOR FILING-UP A WEFT-THREAD FOR LOOMS Filed July 2, 1962 2 Sheets-Sheet 2 United States Patent in Claims. or. 139-224 With looms of a certain type, for example those described in the US. patent specification No. 2,845,093, the weft thread is carried into the warp shed at each pick at a measured length. A weft thread previously cut to its correct length is for this purpose inserted into a shuttle. Thereafter the shuttle is carried over the whole width of the weave through the shed, while the weft thread held fast at one end is taken out of the shuttle and inserted into the shed, so that it can be bound-in behind the shuttle when changing the shed.
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.
It is known to provide as the carrier of the weft thread a hollow body into which the weft thread is blown from the rear by means of compressed air and from which the weft thread is drawn off in the weaving operation through the same opening, i.e. likewise towards the rear. This hollow cylinder has at its frontal face also a second opening in the region where th blown-in air flow carries along the thread in order to make it symmetrical and to obviate a preliminary sortingout prior to the insertion of the weft thread.
With hollow cylinders of this type it is necessary to measure the length of the weft thread prior to blowing it in, and to cut it off at its rear end, which protrudes from the weft thread carrier. One is accordingly forced to perform the cutting-off operation at a predetermined moment. Moreover one is tied down to certain functional laws as regards the place of cutting. Furthermore care has to be taken that the previously measured lengths of the weft are completely inserted into the weft carrier for all gauges of thread, and that only the end required for seizing the weft protrudes from the weft carrier.
, In order to eliminate all the difiiculties and losses of time caused by the aforesaid requirements, 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. In order to attain, this object, it is necessary to take care, that the forward end of the weft thread 3,l95,58ll Patented July 20, 1965 It is another object of the present invention to provide a hollow body which can be used for any gauges of weft threads, since the end blown-in last has not to be sought any more.
It is yet another object of the present invention to provide a device of the kind referred to wherein the operation of cutting the weft thread to pro-determined lengths can be performed at the functionally most favourable moment.
With these and other objects in view, which will become apparent later from this specification and the ac companying drawings, we provide 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 on said leading end of said weft thread emerging from said interior piling-up space.
Preferably 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.
These and other features of our said invention will be clearly understood from the following description of seven embodiments thereof given by way of example with reference to the accompanying drawings, in which:
, 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. 4 shows a second embodiment;
FIG. 5 a third embodiment;
FIG. 6 a fourth embodiment;
FIG. 7 a fifth embodiment;
FIG. 8 a sixth embodiment;
FIG. 9 a plan view of a seventh embodiment in section on the line IX- IX of FIG. 10;
*FIG. 10 an elevation of the seventh embodiment in section on the line X-X of FIG. 9.
In the following embodiments equivalent components are denoted by the same reference characters.
In the first embodiment illustrated in FIGS. 1 to 3, the end of a thread -1 is blown out of a nozzle 2 by means of compressed air through an inlet opening 4 into an interior piling-up space 22 of a hollow body 3. At the other end of the hollow body 3 there is yet .an outlet opening 5 in the direction of blowing, which in relation to the interior piling-up space 22 of the hollow body 3 issues from a diverging portion 16) of the piling-up space lying between said inlet opening and said outlet opening.
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
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. In order to afford to theuair blown-in a further escape from the hollow body, 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
'' the air flow is'guided in a slight arc.
drawing it may alternatively-be directed at an-angle to the axis of the blown-inair new. 7
The sixth embodiment according. to. FIG. 8 shows'a basket-shaped sieve 20 arranged downstream of the thread outlet opening of the hollow body on a holder 21 serving as a slowing-down means.
The last embodiment according to FIGS.. 9 and 10 shows'a flat,j'curved interior piling-up space 22,. wherein The second opening lies however yet in theregion where the blown-in air flow carries along the thread.- The openings 9 are arranged s'ieve-like on the top and bottom of the flat hollow body outside the'main direction :of the airflow. The
slowing-down means consist'likewise, asshown. in FIG.
while the end 10f the thread passes through this outlet. 9
opening .5, only a small proportion ofthe air may flow,
which would flow through the outlet opening 5 when these,
