Description
C~
The present invention firstly rela-tes to a process for kni-tting an article to be closed on itself, for example a beret, in which the article is kni-tted from a first course of s-titches up to a last course of stitches and the respective stitches of the first and last courses are bound two by two.
After having knitted the article from the first to the last course of stitches on the needles of a segment of needle bed of a flat- or circular knitting machine, the knitted article was usually removed from the machine and arranged at a looping station, for e~ample a punch-holder, on the punches of which the two end courses were slid stitch by stitch to assemble these stitches two by two and face to face, and each double stitch thus constituted was bound by means of a yarn for example by a chain stitch.
Such a process presented drawbacks.
It was firstly necessary to provide courses of stitches for gripping the knitted article, adjacent the end courses to be connected face to face, said gripping courses thereafter being out.
The removal of the knitted article from the machine and transfer thereof to the looping station were delicate operations.
The end courses were bound or connected with the aid of a binding yarn different from the knitting yarn. Even if the article -were knitted with a natural yarn, i.e. if the article were dyed after it had been knitted and closed on i-tself, due -to the difference in count of the knitting and binding ya.rns, the latter did not react to dyeing in the same manner, this often resulting in a flaw in shade on the surface of the article where the binding yarn was located.
It is an object of the present invention to overcome these drawbacks, viz. to :
- knit -the exac-t length necessary for the knitted article, - avoid transfer of the knitted article from one machine to another, - and refer questions of dyeing to the yarn manufacturer.
French Patent N 2 364 283 discloses a process in which the first and last courses of stitches of an article are assembled on the same machine. British Patent 13 307 discloses a process in which the first and last courses of stitches are assembled two by -two. However, in these two processes, the first and last courses of stitches are assembled in unstable manner, with the risk of tearing.
The present invention thus relates to a process for knitting an article to be closed on itself, and particularly a beret, in which, on the same machine, a first course of stitches is formed with a knitting yarn, this first course is stored, the article is knitted ~ith the knitting yarn up to the last course of stitches and the respective stitches of the first and last courses of stitches are assembled together two by two, characterized

French Patent N 2 364 283 discloses a process in which the first and last courses of stitches of an article are assembled on the same machine. British Patent 13 307 discloses a process in which the first and last courses of stitches are assembled two by -two. However, in these two processes, the first and last courses of stitches are assembled in unstable manner, with the risk of tearing.
The present invention thus relates to a process for knitting an article to be closed on itself, and particularly a beret, in which, on the same machine, a first course of stitches is formed with a knitting yarn, this first course is stored, the article is knitted ~ith the knitting yarn up to the last course of stitches and the respective stitches of the first and last courses of stitches are assembled together two by two, characterized
2-in that t.he pairs of stitches thus formed are bound by a stable hinding means.
Due to the inventlon, the article is knitted without gripping courses and is closed on itselE, in stable manner, without the necessity of transferring it to a looping station, to close it on itself.
If the finished article is to be plain, it is easy to use the same continuous knitting yarn, in the desired shade, which, at the end of the process, also serves as binding yarn for binding the end courses. The shade of the article is thus uniforme.
In a preferred embodiment of the process of the invention, the stitches of the end courses are bound by at least one portion of knitting yarn passing right through the stitches of at least one of the two end courses of stitches.
The stitches of the end courses may then be assembled as double stitches and these double stitches may be blocked by a portion of the knitting yarn performing a role of assembly and blocking by passing through these double stitches.
In a different embodiment of the process of the invention, the stitches of the end courses are assembled with the sti.tches of the last course of stitches, respectively~ and the pairs of stitches thus formed are bound by a blocking portion of the Xnitting yarn passing through the stitches of the last co-urse performing a role of assembly~
The present invention also relates to a knitting machine for carrying out the above-defined process, comprising, .in manner known per se, a creel having at least one package, a yarn-guide, a first needle bed supporting knitting needles, a sinker support, a second needle bed supporting storage needles, means for driving the knitting and storage needles and the sinkers in translation on themselves, and means for driving the yarn-guide in translation at right angle to the knitting needles, characterized in that it further comprises a comb with stitch bottom control teeth arranged so that its teeth can be respectively inserted between the storage needles and may move therebetween and parallel thereto.
The invention will be more readily understood on reading the following description with reference to the accompanying drawings, in which :

- Fig. 6 is an illustration of a first embodiment of the process of the invention , - Fig. 7 is an illustration of a second embodiment of the process of the invention ;
- Fig. 8 is an illustration of a third embodiment of the process of the invention.
Referring now to the drawings, the description and illustration of the knitting machine of the invention are limited to those parts necessary for understanding the invention, it being understood that the other pieces are neither described nor illustrated in the drawings since they form part of conventional knitting machines which are perfectly well known to the man skilled in the art both by their structure and functioning.
The machine shown in Fig. 1 is intended for knit-ting articles to be closed on themselves, and particularly berets, and comprises a horizontal rectilinear needle bed 1 supporting knitting needl~s 2, a vertical support 3 for sinkers 4, an obli~ue, likewise rectilinear needle bed 5 supporting storage needles 6, a plate or comb 7 supporting control teeth 8 fixed to the plate 7, which will be described in greater detail herein-after, the other members of the machine such as for example the yarn-guide, with its carriage, as well as all the drive devices, not having been shown for the reason set forth hereinabove~
I-t will be no-ted that the needle beds 1 and 5 are rectilinear, and of determined lengths, but -the invention may also provide circular needle beds. The essen-tial is to be able to knit the articles to be closed on themselves on segments of needle bed, further to a reciprocating movement of the yarn-guide.
The ]cnitting needles 2 and storage needles 6 are shaped and arranged in their respective needle beds 1 and 5 so as to be driven in translation on themselves, also in a reciprocating movement, by conventional cam means cooperating with their butts.
In the position shown in Fig. 1, the knitting and storage needles, respectively distant from one another by a determined pitch, respectively interlock in one another.
It is provided, in conventional manner, to displace one of these two needle beds 1 and 5 by a half-pitch with respect to the other for the operations of assembly and binding of the two end courses which will be described hereinafter.
The sinkers 4 are respectively inserted between the knitting needles 2 to control the stitch bottoms of the course of stitches preceding the one being knitted. These sinkers may also be animated by a reciprocating movement of translation by known cam means.
The comb 7 is mounted to be displaced and to pivot so that its teeth 8 can be inserted between the storage needles 6 and move parallel thereto. Any other dispLacement of the comb and/or its teeth to place and displace -the latter in this way may also be suitahle.
From a package of knitti.ng yarn and a yarn-guide arranged to place the knitting yarn on the needles, the beret is knitted, beginning with the formation of a firs-t course of stitches.
The knit-ting and storage needles, in yarn engagement position, interlocXing in one another, with their latches open, the yarn-guide places the yarn to form, with a first porti.on of yarn, a loop on the heads of the storage and knitting needles. The storage needles are lowered and the knitting needles are advanced to move them into advanced yarn engagement position beneath the yarn-guide~ After having mounted the sinkers 4, the knitting needles 2 filled with a second portion of yarn are withdrawn to form the stitches of the first end course with their tops on the bottoms of stitches of the second course under formation and their bottoms on the storage needles 6.
This first course of stitches will remain stored, during the whole knitting operation, on the storage needles 6, only the knittin.g needles 2 continuing to participate in knitting the beret.
The sinkers 4 and the storage needles 6 are located face to face, the sinkers 4 are lowered -to control the bottoms of the stitches of the second course being formed and, after having advanced the knitting needles 2 into yarn engagement pos.ition, the second course of stitches is formed 8~2~
with a third portion of yarn placed on the heads of the knitting needles 2.
Knitting thus contlnues by the formation of successive sectors as taught by the prior art, by successive decreasings and increaslngs, up to -the last co-urse of stitches. This state of t'he kni-tted article, with its two end courses oE stitches, is illustrated in Fig. 2. The bottoms 10 of the stitches of the first course are engaged on the heads of the storage needles 6. The stitches of the last course are engaged, by their tops 11, on the heads of the knitting needles 2 and, by their bottoms 12, on the sinkers 4 and on the `tOpS 13 on the stitches of the second to last course.
The operations for assembling and binding the end stitches are carried out as follows :
The needle bed 1 of the knitting needles 2 is moved in translation by a half-pitch to bring the knitting needles and the storage needles respectively face to face.
The knitting needles 2 are advanced to stretch the loops of the stitches of the last course between the sinkers 4 and the front stops 14 of the knitting needles 2. The storage needles 6 are mounted along the knitting needles 2 through a lateral recess provided to this end on the knitting needles (not shown as it is well known of the man skilled in the art~, and through the stretched loops of the stitches of the last course~ thus transferred on the heads o~ the storage needles 6. T'he sti-tches ll of the last course slide on the 'body of the storage needles 6 by their own weight or possibly with the aid of -the tee-th 8 vf the comb 7 pivoted to t~lis end, into assembly position face to face with the stitches 10 of the first course The sinkers 4 are then retracted and the storage needles 6 thus carrying a course of double stitches, as illustrated in Fig. 3, is lowered.
The knitting needles 2 are advanced and the latches 15 thereof are opened and retracted for example by means of a lug disposed on the carriage of the yarn-guide, then they are withdrawn.
The teeth 8 of the comb 7 respectively inserted between the knitting needles 2 are brought level wi-th the storage needles 6 and are then lowered between the storage needles 6 to control the loop bottoms of the double stitches.
The storage needles 6 are raised to stretch the loops of double stitches between the teeth 8, performing the role of sinkers, and front stops 20 of the storage needles 6, as illustrated in Fig. 4.
To take up the loops of the double stitches on the heads of the knitting needles 2 these needles are advanced again, along the storage needles 6, through the same lateral recess provi.ded to this end on the storage needles, and through the loops of the double stitches, then the knitting needles 2 are withdrawn, their latch open~ after having slightly lowered the storage needles 6 and the tee-th 8. A
spatial triangulation is obtained, of the loops of the double ~iL8~
stitches thus stretched at three points, namely by the heads of the knitting needles 2, -the stops 20 of the storage needles 6 and the control teeth 8. The double s-titches thus stretched are shown in F`iy. 5. It will be noted that they are no longer flat, but that their opening extends substantially transversely to the machine of the invention.
Also to be noted in Fig. 5 is the top 30 of the stitches of the second course of stitches adjacent those which remained stored on the storage needles 6.
The double stitches 10, 11 having been stretched, a sha~t, provided at one end with an eye, is then introduced by this end through all the double stitches identical to those of Fig. 5. The knitting yarn is then threaded through the eye of the shaft which is then withdrawn, in the opposite direction, from the double stitches which are thus traversed by two strands 40, 41 of the knitting yarn (Fig. 5) to bind the stitches 10 and 11 of the double stitches previously formed. Of course, the length of this shaft is at least equal to the useful length of the segments of needle bed of the machine.
The needles, for example the storage needles 6 first of all, are then emptied by raising them so that the double stitches close their latch 16, then by lowering them.
Operation is the same for the knitting needles 2.
Finally, it suffices to displace the comb 7 to disengage the control teeth 8 and recover the article closed on itself.
In summary, -the above-described process of assembly and binding of the two end courses of -the kni-t-ted article consisted in placing the s-titches 10 and 11 two by two and face to face and in assembling and blnding them by at least one or two strands 40 and 41 of the ]cnitting yarn passing therethrowgh. This process is schematically illustrated in Fig. 6. Due to the fact that the strands 40 and 41 pass night through the stitches 10 and 11 like weft yarns, the link between the stitches 10 and 11 is perfectly secure and stable, without any risk of tearing. The stitches are blocked.
Operation may also be carried out substantially differently.
The stitches might for example have been assembled, not directly by these rectilinear strands of the knitting yarn, but by a course of supplementary stitches, formed on the end stitches and by a rectilinear strand as illustrated in Fig. 7.
In this case, -the double stitches 10, 11 are assembled by a course of assembly stitches 70, formed on these double stitches, and they are bound by a strand 80 of the knitting yarn passing through the stitches 70 of this assembly course, likewise in the manner of a weft yarn.
The stitches 10 and 11 may also ha-ve been assembled by passing the stitches 11, performing the role of assembly stitches, through stitches 10 and laying in a portion 90 of the knitting yarn with one or two strands 8~
performing a function of binding through -the stitches 11, as illustrated in Fig. 8.
When felting the beret, the por-tions of the knitting yarn, performing the role of assembly and/or binding, and the end stitches, hoo]s onto one another.
Of course, as has already been stated hereinabove, the portion of assembly and/or binding yarn may be tha-t of a fresh yarn, but it is preferably the yarn used for knitting the article, with determined characteristics.
With the process and the machine described hereinabove and illustrated in the drawings, berets may be knitted, as has been seen, but also any other articles to be closed on themselves, such as for example sheaths for protecting stumps.
Due to the inventlon, the article is knitted without gripping courses and is closed on itselE, in stable manner, without the necessity of transferring it to a looping station, to close it on itself.
If the finished article is to be plain, it is easy to use the same continuous knitting yarn, in the desired shade, which, at the end of the process, also serves as binding yarn for binding the end courses. The shade of the article is thus uniforme.
