Definitions

  • My invention relates to winding and the like machines, especially weft winding machines, and has more particularly reference to the yarn guide appliance of machines of this class.
  • the object of my invention is a yarn guide appliance which,
  • my invention primarily consists in the fact that a yarn guide bar is provided to which an axial reciprocating motion is imparted, and which is provided with grooves, threads, or notches on which the oncoming yarn runs, while two stops are provided for the latter, independently of the reciprocating bar, the mutual distance of these 20 stops being adjustable in accordance with the stroke of the bar.
  • a yarn guide bar is provided to which an axial reciprocating motion is imparted, and which is provided with grooves, threads, or notches on which the oncoming yarn runs, while two stops are provided for the latter, independently of the reciprocating bar, the mutual distance of these 20 stops being adjustable in accordance with the stroke of the bar.
  • the speed of the yarn guide bar may be theoretically an unlimited one, as, in contrast to the known devices in which the yarn guide consisting of several parts has to be reciprocated, it is merely this bar that makes a reciprocating motion.
  • all of these yarn guide bars of a' machine may be actuated separately in dependence upon the appurtenant bobbin spindle gear, or groupwise, or also in unison and independently of the drive of the individual spindles.
  • the adjustable yarn steps may be combinedwith a known feeling device in such a manner as to be advanced in accordance with the progress of the yarn winding work along the grooved yarn guide bar and thus entrain the oncoming yarn by shifting it from one groove to the other. These stops thus limit the reciprocating motion of the yarn and cause its passage from the one groove of the bar to the other, so that the yarn always runs on the grooved bar on that place which is fit at any instant for the formation of the conical shape of the bobbin.
  • the new idea my present invention is based upon'may be applied to all kinds of winding machines having a reciprocating yarn guide, immaterially of whether the bobbin revolves only on its axis or is also moved axially.
  • Fgure 1 is a lateral view, partly in section, of the'parts under consideration of a winding machine equipped with my new yarn guide,
  • Figure 3 is a section on the line IIIl1I of Figure 2, seen from the left.
  • the machine illustrated is a so-called spindleless machine, that means a machine in which the bobbin 4 is arranged between two points 5 and 6.
  • the latter is fixed to the front end of the shaft 8 mounted in the casing 7 and driven in the usual manner by a friction wheel 9.
  • From this shaft 8 is derived, by means of a toothed gear 10, 11 the rotary motion of a cam disc 13 mounted on another shaft 12.
  • By means of an entraining pin 14 in a groove in cam 13 reciprocating motion is imparted to a slide 15 guided in the gear casing '7.
  • the slide 15 has connected to it, by a bar 16 likewise guided in casing 7, one end of a bar 17 which is provided with a plurality of guiding depressions in the form of annular grooves, threads, an-
  • a threaded spindle 19 is mounted likewise in parallel with the bobbin 4 on arms 20, which may swing on a shaft 21 interconnecting the casing 7 and bracket 18.
  • a feeling disc 22 which in known manner co-operates with the bobbin 4 and is shifted on the spindle 19 to the left in accordance'with the yarn winding operation.
  • the bridge 23 further carries two stops 2'7 and 23 for the oncoming yarn 29, which 1 are adjustable in a slot 26 of bridge 23 and can be fixed in position.
  • the yarn 29 is fed from a guide roller 30 mounted on the bracket 18.
  • the stops 27, 28 are bent circularly about shaft 21 so as to be always the same distance from the yarn guide bar 17, independently of the position of the feeling disc 22 relatively to the bobbin 4, which position varies according to the thickness of the yarn and to the kind of the bobbin to be wound.
  • the described mechanisms operate as follows:
  • the yarn 29 is supplied to the eye 25 by means of the guide roller 30 and runs at an acute angle over the bar 17 to the bobbin 4. Since the bar 17 has annular guiding depressions in the form of grooves, threads, notches or the like, the yarn partakes of the reciprocating motion of the bar whereby the cone of the bobbin is formed.
  • the two stops 2'7, 28 assume a position with a mutual displacement H, which corresponds to the stroke H of the cam disc 13 and to the height of the cone of bobbin 4. Now, since the two stops 27, 28
  • stop 28 will shift the yarn to the correct groove while the bar 17 is traveling to its limiting position.
  • the grooved yarn guide bars 1'? of a machine may be reciprocated also in groups or in unison independently of the drives of the spindles and by special means, whereby the whole-construction of the machine is considerably simplified.
  • a rotatable winding shaft having a winding spool mounted thereon, a thread guide bar having guiding depressions therein for engaging the yarn before the winding thereof on the spool, means for reciprocating said bar adjacent the spool on said winding shaft,
  • a unit independent of said guide bar adapted to be moved by the growth of the spool, and stop arms on said unit for shifting the position of the yarn on said guide bar as the winding of the spool progresses.
  • a thread guide bar having guiding depressions therein for engaging the yarn before the winding 35 thereof on the spool, means for reciprocating said bar adjacent the spool on said winding shaft, a unit independent from said guide bar adapted to be moved by the growth of the spool, a guide eye for the yarn on said unit, and adjustable stop 9 arms on said unit for shifting the position of the yarn arriving from said guide eye on said guide bar asthe winding of the spool progresses.
  • a rotatable winding shaft having a winding spool mounted thereon, a threadguide bar having guiding depressions therein for engaging the yarn before the winding thereof on the spool, means for reciprocating said bar adjacent the spool on said winding shaft, a feeling unit independent of said guide bar adapted to be moved by the growth of the spool, and adjustable stop arms on said unit adapted to be mutually positioned in accordance with the stroke of the guide bar for shifting the yarn along the guiding depressions in said bar.
