Definitions

  • the present invention relates to spinning machines including a ring yrail and .retractable yarn guides, the term spinning machine being meant to designate all textile machines including a plurality of spindles .for v,the formation of cops, whether said machines are .used for spinning proper or for any other operation of the ⁇ same kind, such for instance as twisting.
  • This invention Vis more especially but not exclusively concerned with spinning machines in which the spindles are directly driven and in particular driven by means of worms and worm wheels.
  • the object of the present invention is to provide a machine of the above mentioned kind which is better adapted to meet the requirements of practice than those used up to the present time.
  • the present invention relates to spinning machines having a ring rail which is adapted to have, below its normal lowest position, a complementary stroke called underwinding stroke corresponding to the formation, on the base of the cop, of some supplementary turns of yarn intended to be unwound when the cop is removed from the spindle on which it was mounted.
  • the present invention consists essentially in mounting the yarn guides at the ends of retractable arms mounted on a support which moves together with the ring rail and in providing means adapted to cooperate with said arms so as to retract the yarn guides at the beginning of the underwinding stroke of the ring rail.
  • Fig. l is a sectional view on showing an embodiment of the present invention.
  • Fig. 2 is a side view corresponding to Fig. 1.
  • Fig. 3 is a sectional view on the line III-III of Fig. 2.
  • Figs. 4 and 5 are views similar to Figs. 1 and 2 respectively, the yarn guides being shown in retracted position.
  • the embodiment of this invention shown by the drawing is supposed to be applied to a spinning machine which may be of any suitable type.
  • a spinning machine which may be of any suitable type.
  • it includes two rows of spindles 1 disposed in staggered fashion and driven by a shaft extending between these the line I-I of Fig. 2, device according to the ICC two rows of :spindles ⁇ and carrying 4a plurality of worms which drive worm wheels-carried by the spindles.
  • This spinning machine includes a ring rail r which -is controlled -in conventional fashion so that it can have below its lowest normal position an lunderwinding supplementary .stroke intended to bring -it "below this lowest normal-position.
  • the spinning machine further includes, in .line with every spindle 1, a yarn guide 2 'disposed at the -end -of a retractable arm '3 mounted on a support 4 (which may be constituted by an inverted U-shaped iron running along the whole length of the corresponding ring rail). Every arm 3 is pivoted about an axis-5 and extends 'horizontally transversely to support 4 Iwhen the yarn guide 2 s-in line with the-corresponding spindle 1.
  • Support 4 participates in the vertical movements lof the-ring rail and, 4for instance, there is one support '4 ffor every section of the spinning machine, vtwo successive supports 4 bei-ng connected together by a sleeve I6 Yslidable on a fixed column ⁇ 7 ofthe machine.
  • Sleeve 4 fis connected to -the lvring rai-l so that it Aparticipates ⁇ in the vertical movements thereof.
  • I provide, in cooperation with arms 3, control means adapted to work when the ring rail is starting on its supplementary underwinding stroke to bring the yarn guides into retracted position.
  • the above mentioned means include fixed abutments carried by the frame of the machine and movable cooperating abutments participating in the vertical movements of support 4 butv slidably guided with respect to said support so as to pivot arms 3 upwardly.
  • the last mentioned movable elements consist of side bars 8 disposed on either side of support 4 and vertically guided with respect thereto so as to be able to move upwardly with respect to said support.
  • said side bars 8 have horizontal extensions 9 which normally rest upon support 4.
  • Figs. 4 and 5 show the relative positions occupied by the parts of the machine when the ring rail is reaching the end of its downward underwinding stroke.
  • arms 3 are extending obliquely for this position so that the mere action of gravity is suicient to return them into horizontal position when the ring rail moves up to its normal lowest position, and therefore side bars 8 are returned to the position with respect to support 4 as illustrated by Figs. 1 and 2.
  • the improvement according to the present invention is especially advantageous in the case of spinning machines the spindles of which are located very close to one another.
  • a spinning machine which comprises, in combina- 8 during the underwinding ring rail are provided fixed tion, a frame, a plurality of parallel spindles rotatably mounted on said frame, a ring rail structure slidable in said frame in a direction parallel to said spindles, said structure having a normal reciprocating movement of given amplitude in said direction and a supplementary underwinding stroke beyond said amplitude, guides for the yarns wound on said spindles respectively, arms carrying said guides movably mounted on said ring rail structure for retraction of said guides ,from their positions in line with said spindles respectively, and cooperating means respectively carried in iixed position by said frame and movably guided by said ring rail structure for automatically actuating said arms to retract said yarn guides in response to the movement of said structure beyond its normal amplitude to perform said supplementary underwinding stroke.
  • a spinning machine which comprises, in combination, a frame, a plurality of parallel spindles rotatably mounted on said frame, a ring rail structure slidable in said frame in a direction parallel to said spindles, said structure having a normal reciprocating movement of given amplitude in said direction and a supplementary under-winding stroke beyond said amplitude, guides for the yarns wound on said spindles respectively, arms carrying said guides pivoted to said ring rait structure about axes at right angles to said spindles to permit retraction of said guides from their positions in line with said spindles respectively, side bars guided on said ring rail structure slidably in a direction parallel to said spindles, and fixed parts carried by said frame to engage said side bars when said ring rail structure is having said supplementary underwinding stroke, said side bars being so positioned withV respect to said ring rail structure as to engage said arms and pivot them upwardly when said fixed parts engage said side bars.
  • said arms are obliquely disposed so that when said arms are no longer acted upon they return to horizontal position under the mere action of gravity.
