Definitions

  • the present invention relates to a method and device for weaving of fabrics.
  • the main object of the present invention resides in a substantial acceleration and simplification of the weaving operation.
  • the inserting (picking) of the weft thread into the shed by means of an air jet is made use of.
  • the invention aims further to a substantially simpler and at the same time more efiicient arrangement of a pneumatic weaving loom,
  • the weaving operation is effected in such a way that one or a plurality of weft threads are inserted into a conventional shed of warp threads either from one or from both sides of the Warp by means of air jets surrounding and entraining the weft thread or threads.
  • the required rotation in the direction of twist of the weft thread is preferably imparted to such jets so as to prevent tearing up the thread and to smooth the picking motion.
  • each picked thread is retained at the opposite side of the warp by a marginal binding for instance by a gauze-like crossing, i. e. binding of the Weft and warp threads at the margin of the fabric, Whereas the rear portion is clamped by tensioning means and, if necessary, additionally secured also by a marginal binding, whereupon by a blow of the reed the weft thread is tensioned under simultaneous braking of the leading portion by the marginal binding and clamping of the rear portion by the The thread is finally out off, the shed changed and the weft thread Woven in.
  • a marginal binding for instance by a gauze-like crossing, i. e. binding of the Weft and warp threads at the margin of the fabric
  • the individual batches of air for each picking motion of the weft thread are adjusted exactly to a quantity which is just sufficient for causing the front wave of the air jet, by its impact against the free end of the weft thread, to straighten out the thread and impart thereto a suitable acceleration producing a flying movement, whereupon the pressure gradually drops.
  • the weft thread is first unwound from a storage source in the requisite length, subjected to the entraining influence of a jet produced by a predetermined batch of compressed air, driving the wound-off portion of the thread through the shed, the thread retained at the end of the fabric remote from the nozzle and tensioned by a pull acting in a direction opposite to the direction of the picking movement and after having been woven in it is cut off and its free end retracted towards the nozzle,
  • a device for carrying out such weaving process corresponds to a mechanical loom insofar as there remain the driving means for the warp, whereas the operating means for the weft, including its safety catches (weft stop motion) are replaced by a pneumatic apparatus for inserting the Weft into the shed, as will be described later.
  • the operation of such a pneumatic loom is noiseless, cheap and very quick. With approximately half the input of driving force about double the number .of pickings, or even more may be achieved as compared with hitherto known looms.
  • a pair of cooperating retracting rollers engaging the thread said rollers revolving in a sense so as to impart movement to the thread opposite to the direction of picking and in one or in both rollers a relieving-recess is provided, said recess being adapted torelease the thread from engagement with the retracting rollers in the moment of operation of the air nozzle.
  • One or both retracting rollers are preferably yieldingly mounted so as to allow for irregularities in the thickness of the thread.
  • a throttling valve In the supply of compressed air a throttling valve is provided, and a storage chamber for compressed air interposed between the throttling valve and the nozzle, the throttling valve admitting into the chamber such amount of air only as is required for one picking operation.
  • Figure 1 is a diagrammatic sectional view of an example of the weft inserting means
  • Figure 2 shows a detail of the nozzle
  • FIGS. 3, 4, 5 and 6 show the succession of the individual phases of operation in diagrammatic representation

  • the valve I? of the nozzle 18 is temporarily opened by the influence of the projection 2? on the cam disc 21 acting on the follower roller is of the lever 24 and the emerging jet of compressed air, accumulated in the chamber 2i tensions the weft portion 2, remaining after the weft has been cut off, and directs it to the shed.
  • the weft :thread is 'tensionedby a blow of the reed and inthe last phase woven inby the change of the shed, cut offby a cutting edge 23, Fig.5, whereupon the whole, process is repeated.

  • Arelieving recess l9v is provided in one or in both, of the, rollers, in the example shown in the roller 41 andpreferably at least one of the retracting rollers .is yieldingly mounted.
  • the arrangement is such that the thread 34 passes in a straight line from the supplying device (winding-off apparatus) throughthe rollers 41, 48 into the passage-33 of the nozzle 3i.
  • the relieving recess 4% in-the-rollerfl assumes approximately .the position shownin Fig. 8 in which. it relieves the thread 34 from thread is seeuredby a gauze-like,- crossingimthe marginal portion of the fabric, for instance in the width of 3 or more warp threads at the end which is remote from the nozzle.
  • the rollers 41 and 48 have already rotated to such an extent from the position shown in Figure 8 that the full circumferential portion of the roller 41 engages the thread 34 and exerts now a pulling action thereon in the direction of the arrow P in Figure 8, tensioning thus the thread.
  • the winding-off apparatus for preparing the weft thread may also b modified and examples of such modified arrangements will now be described.
  • the device comprises a winding-off drum which is preferably slightly conical, as illustrated in the drawing.
  • is rigidly secured to a shaft 52 which receives movement from any desired driving mechanism, not illustrated, for instance through a gearing from the main shaft of the machine.
  • the shaft 52 is supported in bearings 53, 54, mounted in a rigid sleeve 55 in the frame of the machine.
  • a gear 58 is rigidly keyed on, said gear being a so-called sun-gear of a planet differential gearing which will be described later.
  • a carrier 59 is secured to the bottom of the drum 5
  • is in engagement with a driven gear 62 which is rigidly secured to a disc 63 which in the following description will be called casting-off disc. From the embodiment as illustrated it is apparent that upon rotation of the shaft 52 through one revolution, the drum 5
  • is provided with a shallow groove 64 which serves for mounting a guide 51 for the thread and further there are two thread entraining dogs having the form of projections 65 (see also Figure which are positioned diametrically opposite each other.
  • Th disc 63 is provided with one extension 66 which in the following description will be called casting off member. This extension 66 is slightly higher than the projection 65 on the drum 5!.
