Definitions

  • the present invention refers, as expressed in the title of this specification, to a series of improvements introd­uced in the stretching means of rectilineal knitting ma­chines, improvements which are centered in the establish­ment, along the machine, of a plurality of modules or sec­tions, operatively independent, each of them materialized in an individual motor and driven independently from the others, so that different stretching areas can be establish­ed, in a variable number, along tht textile piece to be ob­tained and that, in consequence, the global stretching ten­sion for the textile piece in its whole may also be varied at will not only from one piece to another, but also within one same piece, and in a fully automatic mode, concretely through the electronic means of government of the machine, which will also govern the actuation of such motors in ac­cordance with a program set forth to that purpose.
  • the conventional stretchers of the rectilin­eal knitting machines do not offer an adequate stretching that serves for the majority of the new structures of the knit and for the different types of fibers that have been incorporated to the present collection.
  • the number of sets per passing of the carriage has been increasing, so that as from the classical solution with a unique set or sys­tem, it was later on passed to two, afterwards to three, until getting to the four sets which are used at present, with which number of sets, the stretching systems used, more than inefficient, result insufficient.
  • said improve­ments consists in sectioning the stretching means in a plurality of consecutive and operatively independent mo­dules, so that each of these modules, apart from what may happen with the others, will result operative or not at each moment, in accordance with the previously cited programming.
  • each module materializes in a motor which stator is located in the inner part and is conveniently fastened to an axle, common to all the modules and which is kept static, whilst the rotor results in a housing for the cited st­ator, is mounted with freedom of rotation on said axle through bearings and incorporates a perimetral recover­ing on basis of rubber, synthetic rubber or any other adequate material so that, when inciding on its rotat­ion over the surface of the fabric and against the cor­responding and classical adjustable pressure roller, it provokes the dragging and consequent stretching purs­ued.
  • This modularity in the stretching means allows, by means of the adequate control of the motors correspond­ing to their different modules, that tractions on the fabric take place, in specific areas of same, in the absence of traction in other areas, and that all of the­se may be variable at will, without any limitation to that purpose.
  • a conventional rec­tilineal knitting machine is made up as from a frame­work in which, at the upper part, are established two comb plates 1-1 ⁇ , with their corresponding sets of nee­dles 2 which, duly actuated by the carriage, give rise to the fabric 3 which is moved vertically and downward­ly between said comb plates, dragged by the stretching means, conveniently materialized in a dragging roller 4 and a pressure roller 5, the latter mounted tiltably on a support 6 and provided with adjustable pressure means 7 on the dragging roller 4.
  • the im­provements preconized are centered in the fact that in­side the dragger roller are established a plurality of independent sections or modules 81, 82, 83, ...8 n , all of them mounted on a main axle, fixed 9, concretely the fra­mework of the machine, being all these sections or modul­es 8 independent in-between from the operational point of view, that is, that whilst a module is found under an ac­tive situation, another module adjacent to the former may be found in an inoperative situation, and viceversa, be­ing it attained, in this way, a variable stretching sys­tem, according to the needs and shapes with which the fa­bric is being configurated.
  • each module 8 is materializ­ed in a motor which stator 10 is solidarized to the axle 9 and in consequence results unmoving, like the latter one, which fastening is carried out by means of the scr­ews 11 or by any other conventional means.
  • the rotor 12 is mounted, with free rotation, by means of extreme bearings 13 and 14, being said rotor provided with a perimetral recovery 15 of rubber or syn­thetic rubber, adequate for the stretching of the fabr­ic.
  • the axle 9 is provided with a longitudinal slot 16, through whi­ch the wires 17 pass, for the feeding of the coiling 18 of the stator of each motor, apart from the remain­ing ones, and in accordance with the signals received by the brain or control system of the machine where, ac­cording to the fabric to be obtained, it is duly sched­uled the actuation of the needles 1, and, with regard to the improvements of the invention, the instants of actuation and the timing of each of the motors 10-12 to attain the variable stretching required by said fa­bric.
