Abstract

AIR JET SPINNING MACHINE. THE AIRJET SPINNING MACHINE 1 IS DESIGNED AS A TAPE CONTAINER 16 LOCATED BELOW, AND A WINDING UNIT 5 LOCATED ABOVE, A STRETCHER SYSTEM 3, AS WELL AS A UNIT AIR JET SPINNERS 4, ARE ARRANGED TO PERFORM A "UPHILL SPINNING". BY SUCH A PROVISION, ALL OF THE ELEMENTS 16, 3, 4 AND 5 USED FOR THE EXECUTION OF THE SPINNING PROCESS ARE LOCATED ON THE SAME SIDE OF THE MACHINE, WHICH ALSO ALLOWS THE CONSTRUCTION OF A TWO-SIDED MACHINE. THE STRETCHING SYSTEM 3 AND THE SPINNING UNIT 4 CAN BE PLACED IN A HORIZONTAL POSITION (SHOWN AS A MIXED LINE) A VERTICAL POSITION (CONTINUOUS LINE) OR AN INTERMEDIATE POSITION. ELEMENTS 3, 4 AND 5 ARE ARRANGED ON A MACHINE UPRIGHT WHILE THE TAPE CONTAINER 16 IS STANDING ON THE FLOOR 15.

Description

1. The subject of the invention is an air jet spinning machine arranged for

  receive a pot for ribbons, then a drawing system, to resume and stretch a ribbon of fibers taken from the pot, and, placed next, seen in the direction of the succession of operations, a

  air-jet spinning unit following the system

  to obtain a spinning thread, as well as a unit

winding for the latter.

  It is well known that one of the advantages of what is known as air jet spinning is that the ribbons can be turned directerment-by spinning into one.

  But the ribbons are delivered in pots, which requires

  site that in the constructive concept of spinning machines

  air jet, it includes a supply of pots.

  Air jet spinning machines, which have been on the market so far, have a constructive concept in

  which the supply of pots is arranged on the front side.

  while the spinning process is provided on the front, or service side, of the machine The ribbon is fed to the machine by feeding a drafting system

  interposed before the spinning process itself.

  spinning unit, arranged after the drawing system, provides

  finished yarn at a winding unit provided below.

  The essential disadvantage of this constructive concept lies in the fact that only machines used on one side can be produced because of the arrangement

  pots on the back side, which requires a

  This disadvantage weighs heavily in the case of

  the production of fine yarns, as produced by

  air-jet spinning machines, since the clutter

  specific is usually high for fine yarns.

  Another disadvantage lies in the fact that

  positive winding is placed very low and, therefore, in a position unfavorable to the performance of the service and monitoring.

  The invention therefore proposes to obtain a consistent concept

  a trick that allows, with equal footprint, a production of 2. more important yarns, under more favorable conditions of service. This object is achieved according to the invention in that the ribbon pot, the drawing system, the air jet spinning unit and the winding unit are on the service side of the spinning machine. air jet and that the pot is placed underneath and the winding unit above the system

  stretcher and air jet unit.

  The advantages that we obtain, thanks to the invention,

  resident, in addition to the possibility of constructing a ma-

  in that the arrangement of the winding unit at the highest position makes it possible to deliver the coil to the upper part of the machine and to transport it farther on this plane; another advantage is that the fiber ribbon does not have to make long journeys, with the proper guidance necessary to

  this effect, between the pot and the drawing system.

  The invention will now be described in more detail

  with reference to the annexed drawing showing modes of

  given merely by way of examples which are in no way

  tive. In this drawing Fig 1 is a schematic view of an air jet spinning machine according to the invention, the essential elements of which

  are shown in cross section.

  Fig 2 shows a variant of the spinning machine

with air jet of Fig 1.

  Fig 3 shows a variant of a part of the machine

of Fig 1 or Fig 2.

  An air jet spinning machine 1, the frame 2 of which is shown in dashed lines, comprises a drawing system

  3, an air jet spinning unit 4 and a bobbin winding unit

swim 5.

  The drawing system 3, the air-jet spinning unit 4 and the winding unit 5 are not, in themselves, the object

  of invention and it will suffice, without going into more

  tails, to expose: that the stretching system 3 comprises a pair of input rolls 6 and a pair of 3. output cylinders 7; that the air jet unit 4 comprises a

  torsion donor 8, followed by a pair of cylinders

  9; that the winding unit 5 comprises a deflection roller 10, a back and forth 11 for moving the wire, a drive cylinder 12 and a coil 13 mounted

rotating on a reel holder 14.

  Below the pair of inlet rollers 6 is placed, standing on the floor 15, a ribbon pot 16 from which the fiber ribbon 17 to be stretched and spun is taken for

  feed the pair of input cylinders 6.

  The finished yarn delivered by the pair of rolls of

  output 9 is wound on the winding unit 5.

  By this particular arrangement, in which the success

  transfer of operations is done starting at the bottom to end at the top of the machine, to achieve what can be called "spinning up", in which the pot

  16 fiber ribbon is below the system labeled

  Figures 1 and 2 show that all the elements of which the service personnel have the care of

  hoeing 5, are provided on the same face of the machine, that

we call the sergice's face.

  Sometimes, according to another arrangement of the whole -

  of the installation, ie whether the service is to be performed purely by hand or when it is done

  However, this position is not mandatory for the

implementation of the principle of the invention.

  In Fig. 2, due to the oblique arrangement of the drafting system 3 and the air jet unit 4, the

  An optimal range of inclination in this respect is, depending on the length of the stretcher and the unit

  of air-jet spinning, between 25 and 45 The inclination

  and a dotted line 20 shown in FIG.

  The line 20 joins the pinching line of the cyinders of

  6 at the nip of the exit cylinders 9.

  This connecting line 20 is in an imaginary plane

  perpendicular to the surface of the ground.

  As also shown in FIG. 3, it is possible to use, according to the invention, not only as shown in FIGS. 1 and 2, drawing systems in which the path of the yarn takes place in a straight line, but also drawing systems. o the path of the yarn takes place along a line

  3 'similar to a line of buckling.

  The invention encompasses the basic arrangement of the ribbon pot 16, the drawing system 3, the spinning unit

  4 and the winding unit 5, without

  the details of these elements, all the elements

  named, 16, 3, 4 and 5, being well known by various pu-

blications.

  FIGS. 1 and 2 allow, moreover, to understand that the arrangement, in accordance with the invention, is usable on a one-sided machine as well as on a machine.

to what is shown in Fig 1.
