Definitions

  • the present invention relates to a method for closing a knitted tubular manufacture at an axial end thereof, at the end of its production cycle on a circular hosiery knitting machine or the like.
  • knitted tubular manufactures such as for example hosiery items
  • hosiery items are generally produced by means of circular hosiery knitting machines and are unloaded from the machine with both their axial ends open.
  • the various techniques proposed so far can be divided into two main categories: a first category which comprises the techniques based on the execution of the closure directly on the machine that produces the manufacture, at the beginning or at the end of its production, and a second category which comprises the techniques based on the execution of the closure in a sewing or linking station provided for this purpose, which is spaced from the machine for producing the manufacture.
  • the first category has the drawback of limiting significantly the productivity of the machines, since the closing operation requires a certain amount of time during which the machine cannot produce a new manufacture.
  • the second category to which for example the technique described in patent IT1,300,622 belongs, can at least partially obviate this problem since the productive potential of the machines is penalized only in terms of the time required to remove the manufacture from the machine that produced it, after which the machine can start producing a new manufacture while the previous manufacture undergoes sewing or linking.
  • the aim of the present invention is to provide a method for performing the closure of a tubular knitted manufacture that is capable of improving the background art in one or more of the above mentioned aspects.
  • an object of the invention is to provide a method for closing a knitted tubular manufacture which allows to increase significantly the productivity of the method and of the apparatus.
  • Another object of the invention is to provide a method for closing a knitted tubular manufacture that is capable of reducing the cycle time while maintaining the transfer operations extremely precise.
  • Another object of the invention is to provide a method for closing a knitted tubular manufacture that is highly reliable, relatively easy to provide and at competitive costs.
  • FIG. 1 is a front view of a circular hosiery knitting machine or the like
  • FIG. 2 is a front view of a portion of the circular machine of FIG. 1 during the initial step of production of the manufacture
  • FIG. 3 is a top view of a portion of the circular machine of FIG. 1 in a step that is intermediate between the initial step of production of the manufacture and the step of individual gripping of the loops of knitting by virtue of pickup elements;
  • FIG. 4 is a front view of the machine portion of FIG. 3 ;
  • FIG. 5 is a front view of a portion of the circular machine of FIG. 1 during the step of individual gripping of the loops of knitting by virtue of pickup elements;
  • FIG. 6 is a front view of a portion of the circular machine of FIG. 1 during the step of removal of the manufacture from the machine;
  • FIG. 7 is a view of the machine in the condition of FIG. 6 from a different and partially sectional viewpoint
  • FIG. 8 is a top view of a portion of the circular machine of FIG. 1 during a step of positioning the manufacture at a sewing or linking station 102 ;
  • FIG. 9 is a front view of the machine portion of FIG. 8 .
  • the method for closing a knitted tubular manufacture at an axial end thereof, at the end of its production cycle on a circular hosiery knitting machine 100 or the like comprises:
  • the machine 100 has a yarn guiding plate that can be lifted and lowered, a cylinder 101 , a step motor for the movement on command of an internal tube in order to bring the knitting to the working position, a cylinder locking piston, a knitting pusher piston, a pickup arm 43 with corresponding piston, a yarn guiding plate, an internal knitting lifting tube, an inverting piston, a dial.
  • the commands comprising—the command for stopping the machine
  • the machine furthermore has a knitting pusher of the cylinder, a step motor and an electric throttling valve associated with a suction apparatus, a step motor for the movement of the sinkers, a step motor associated with the internal knitting lifting tube.
  • the second step of extraction of the manufacture comprises the following commands:
  • the machine furthermore has a piston associated with a lower inverting unit, a sensor for transferring the manufacture, a step motor and an electric throttling valve of the sewing machine, and a blower device for the extraction of the tubular manufacture.
  • the third step of transfer of the manufacture comprises the following commands:
  • the invention achieves the intended aim and objects, providing a method capable of increasing significantly the productivity of the machine.
  • the materials used may be any according to the requirements and the state of the art.
