Definitions

  • the present invention relates to a method for forming a seamless tubular knit on a straight knitting machine comprising two needle guiding needles for knitting needles, means for selecting these knitting needles, trolleys for moving the selected knitting needles. and guiding members of the knitting yarn, and a straight knitting machine for carrying out this method.
  • the US 3,456,459 refers to a circular loom, having a cylindrical needle bed associated with a tray.
  • the cylindrical needle bed is divided into four areas with needle grooves controlled by a ring of cams and separated by spaces.
  • Wire guides are mounted on a circular rail and are adapted to move alternately in both directions depending on the direction of movement of the cams.
  • This craft is designed to function as a straight line craft, but it does not allow for decreases or increases, the race of the wire guides being constant.
  • the US 4,724,687 refers to a yarn feeding apparatus for a tubular fabric knitting machine in which the needles of the two needle beds intersect and in which only the needles of a needle bed are working while those of the other needle bed are at rest and vice versa. The production of such a craft is therefore extremely low.
  • the object of the present invention is to produce a seamless tubular knit on a straight knitting machine, which can overcome, at least in part, the aforementioned drawbacks.
  • the present invention firstly relates to a method for forming a seamless tubular knit on a straight knitting machine of the aforementioned type, as defined by claim 1.
  • this method relates to the formation of two tubular bodies joined together in a single tubular body, allowing to achieve a seamless pants.
  • This invention also relates to a knitting machine for carrying out the knitting process, as defined by claim 3.
  • This invention has the advantage of allowing the manufacture under economic conditions of a product according to the document EP-A-0 905 298 .
  • the knitting process according to the invention can not be implemented on a conventional straight knitting machine, but requires a new concept of trade rectilinear, explaining that only by imagining a new concept of knitting, radically different from that usually used in straight knitting machines, the invention was born. It was indeed necessary to create a concept for knitting two separate knit layers, one on each needle bed by continuously joining them by a transfer of the knitting threads from one needle bed to the other, thus allowing the formation of a tubular element without sewing. From this principle, it becomes possible to imagine the simultaneous realization of two tubular elements side by side, which can then be combined into a single element tubular by selecting the needles separating the two tubular elements.
  • the knitting machine illustrated by the figure 1 is a rectilinear loom comprising two needle beds 1, 2, which form either two parallel planes or, as illustrated in this figure 1 , the planes of these needle beds form between them an acute angle such that the knitting needles 3, in their normal course of knitting, do not intersect, as illustrated by the figure 2 .
  • a plurality of carriages 4 are arranged along the needle beds 1, 2. These carriages 4 are integral with a chain or drive belt 5.
  • This drive chain 5 forms a closed loop by rotating around two drive disks 6, rotatably mounted around two respective vertical shafts, one of which 7 is visible on the figure 1 .
  • the carriages, integral with this drive chain 5, therefore always move in the same direction. In the example described, this direction is that of the arrow F, so that these carriages 4 pass successively from one needle 1 to the other needle 2 and vice versa.
  • a guide rail 8 forms a closed loop whose plane is parallel and located above the closed loop, formed by the driving chain 5.
  • Sliding supports 9, illustrated in more detail by the Figures 6a, 6b are engaged with the guide rail 8 and are slidable freely along this rail.
  • a wire guide 10 is suspended from each sliding support 9.
  • the upper end of the wire guide 10 terminates in a hooking element 10c of semicircular shape, while the sliding support 9 has a groove longitudinal attachment 9a open at both ends, to allow the fastening element 9a to exit from the rear of the longitudinal groove 9a and to return from the front, considering the direction of movement of the sliding support 9 .
  • Each carriage 4 carries a bracket 11 whose horizontal arm 11a extends just below the guide rail 8.
  • This horizontal arm 11a constitutes a slide in which two pushers, an upper pusher 12 and a lower pusher 13 are slidably mounted. each of these pushers being secured to an ankle 12a, respectively 13a.
  • the role of these pushers 12, 13 is to push the sliding supports 9 and the wire guides 10 along the guide rail 8.

  • Each of these transfer members 14 has two parts 14a, 14b ( figure 5a ), forming between them a guide groove 16, each of the two parts being integral with an arm 15a, 15b of a suspension member 15 ( figure 1 ).
  • the outlet end of the guide groove 16 is closed by a retractable valve 16a, retained by a spring 16b and used to retain the wire guide 10 during its transfer from a bed of knitting needles 3 of the one of the needle beds in knitting needles 3 on the other of the needle beds.
  • the wire guides 10 comprise, along their rod, a guide portion 10a whose section is ovalized to facilitate guiding in the guide groove 16.
  • the top of this guide portion 10a has a projection 10b intended to come into contact with the upper face of the transfer member 14, thereby defining the vertical position of the wire guide 10.
  • the upper face of the transfer member 14 is shaped as a cam to lift the wire guide 10 during the transfer and put it out of range of the knitting needles 3 and to bring it back to its initial level after the transfer.
  • each of the suspension members 15 is also connected to an adjusting nut 18a, 18b, 18c, 18d engaged with a threaded rod 19 having four sections 19a, 19b, 19c, 19d, threaded with not reversed with respect to each other .
  • One end of this threaded rod 19 is integral with an adjusting member 20, which may advantageously be a stepper motor. The role of this adjustment member 20 is in particular to adjust the spacing between the transfer members 14.
  • the adjusting nuts 18a, 18d carry an arm 77a, respectively 77d, while the adjusting nuts 18b, 18c each carry two arms 77b, respectively 77c.

  • Such organs 39 are visible on the figure 4 . It can be seen that they are constituted as a kind of combs allowing the knitting needles 3 and the knitting yarns to pass.
  • These holding members 39 each rest on a support bar 39b. As we see on the figure 4 the portions 39a of the holding members which extend above the respective upper edges of the needle beds 1, 2 are thinned, thus leaving room for the formation of the knit stitches during the descent of the knitting needles 3 in the grooves for guiding the respective needle beds 1, 2.
  • the figure 16 illustrates a detail of the guide portions of the guide wire 10 which each comprise a free ring 10e held between two annular stops 10d.
  • This free ring 10e has a diameter substantially greater than that of the wire guide rod 10, but less than that of the two annular stops 10d, so that it is free to move between these stops 10d.
  • the wire guide 10 can rotate relative to the direction of the wire 52.
  • the rotation of the wire guide 10 has no effect on the wire 52 which can rotate relative to the wire guide 10 to keep the same orientation defined by the position of the wire feed spool.
  • the knitting cams (not shown) of the carriage 4 engage the needles 3 which follow one another along the needle bed 1, thus raising and lowering these needles which knit the thread that the guide presents them -fil 10.

  • each creel 24 carries four feeding reels 23 of knitting yarn, which corresponds to four threads per knitted leg and eight threads when knitting the top of the pants. Given the increases and decreases in the width of the knit, it may be necessary to change the speed of the carriages 4 to take the wire guides 10 at the output of the transfer members 14.
  • the servomotor 35 must return the carriage 4 to the zero position, that is to say in the position where it is not possible. found neither in advance nor behind the reference distance between the carriages 4.
  • the knitting needles 3 When the knitting needles 3 are selected in order to increase or reduce the diameter of the knitted tubular member or elements, it is necessary to modify the positions of the transfer members 14 so that they follow these changes in diameter. This adjustment is performed by the worm 19 and the stepping motor 20. Due to the inversions of the threads of the various sections 19a, 19b, 19c, 19d of the worm, when knitting the two legs of the pants, following the direction of rotation of the screw 19, the transfer members 14 delimiting in pairs the two legs of the pants are moved together or away from each other.
