A panty-hose product is processed on a two-needle bar knitting machine with a continuous rotating motion so as to form two tubular product at one and the same time with the two needle bars and with different feeds or descents of yarns, whereas the panty portion is formed with a connecting zone cut in the lengthwise direction; needles of the two needle bars are activated in said connecting zone so as to form a structure of ribbed stitching with plain and purl stitches next to each other.
Description
The invention concerns an improved procedure by means of which a panty-hose product or the equiva-lent can be made directly on a machine by using circu-lar machines which produce stockings or socks and which are of the two-cylinder type or have a cylinder and plate with radial needles but in any e~ent have two needle bars of cooperating needles.
The in~ention also concerns a machine fi-tted to carry out the method of the invention and also a pro-duct obtained with the method in question.
As compared to other known embodiments, the in~ention fulfils its purpose of ensuring greater stead-fastness in the connections between the two parts of the product along the line of the crutch, of permitting simpler and also faster processing and of obtaining a satisfactory aesthetic appearance.
The invention is applied to a procedure Eor the formatlon of a panty-hose productc~rthe like by means of knitting machines with two needle bars and, in par-ticular, with opposed cylinders or with needles of one cylinder and radial needIes of a plate, the processing being done with a continuous~motion of rotation~ where-by two tubular products are formed at one and the same time with the two needle bars and with different feeds or descents of yarns, and whereby the panty portion is formed with parts of tubular products with a lengthwise connect.ing zone cut in a lengthwise direction.
. "~ , .
According to the invention, needles of the two needle bars are activated in said connecting zone so as to form, with one feed or a plurality of feeds or even with all the feeds, a structure of ribbed stitching with plain stitches and purl stitches next to each other.
The structure of the ribbed stitching can be of a I : I type, namely with one plain stitch and then one purl stitch.
The connecting zone can be formed of two ban~s~
namely zones of ribbed stitching separated by a tract having 'chreads which are not knitted~ where the cut is made; each band is formed of some rows of stitches which are alternately plain and purl.
The connecting zone can be made with a number of courses greater than (two times greater, at the most) that o~ the neighbouring textures.
The invention also concerns a machine to carr~
out the aforesaid procedure, said machine being of a type wherein two needle bars of needles cooperate with cam-wise drive means that activate the needles of one needle bar in correspondence with some feeds and also the needles of the other needle bar in correspondence with other feeds, so as to form two products, one inside the other, whereby means are envisaged to drive needles of a connecting zone so as to connect the two products lengthwise, and also to carry out a lengthwise cut in said zone in order to form the line of the crutch.
Accordiny to the invention the machine comprises an arc of corresponding needles in both the needle hars, where-by said needles are intended to form said connecting zone and are suitable for being driven, with one or several feeds or all the feeds, so as to take the thread alternately with needles of one or the other of the needle bars in order to form rows of ribbed s-tit-ching.
A further ob~ect of the invention is a panty-hose product or the like made with the procedure and with the machine defined hereinbefore.
The invention will be understood more readily by examining the description and attached figures, wherein a practical but not restrictive example of the inven-tion itself is shown, and wherein: -FigO 1 shows diagrammatically a section of the product in the process of being cut, bent outwards and spread out;
Fig. 2 shows a detail of Fig. l after the produc-t has-,been bent outwards;
Fig. 3 shows a portion of fabric with the pro-gress of the course of stitches corres-ponding with the connection alon~ the line of the crutch;
\
f~
Figs. 4 & 5 show in perspective a portion of the product before and while it is ben-t outwards;
Fig. 6 shows a part of the product after it has been bent outwards;
Figs. 7 & 8 show the position of the needles of two opposed cylinders during two successive moments while the body of the product is being formed;
Figs. 9 & 10 give an elevation and a plan view, both in linear development, of a position of the needles of a cy-linder and plate during a moment in the processing of the body of the product;
Figs.ll & 12 are like Figs. 9 & 10 but show the position of the needles during a successive moment.
According to the details shown in the attached figures, the formation of a double tubular fabric is envisaged as ta]cing place by means of two sets of nee-dles on two needle bars.
Figs.9 to 12 inclusive show a lay-out wherein are visualized a needle bar or bed of needles in a cy-linder and a bar or bed of radial needle hooks 13 in a plate or disk combined with the cylinder. AI, A2, A3 and A4 indicate four positions of yarn feed with thread guides GI, G2, G3 and G~. When the needles II take the thread, they form plain stitches, whereas when the needles 13 take the thread, they form purl stitches.
Normally, so as to form two semi-finished tubular pro-ducts 15 and 17 at the same time with continuous mo-tion, the needles 13 take the thread in correspondence with the feeds ~2 and A4, whereas the needles II take the thread in correspondence with the feeds AI and A3;
the two tubular elements having the reference numbers 15 and 17 respecti~ely are thus formed progressiveiy at one and the same time.
To form the body portion of the product (at the beginning or end of formatlon of the whole product) it is necessary to make a connection between the two fa-brics and a cut along a tract of the lengthwise develop-ment of the two tubes of fabric, as indicated with T
in Fig. ~ and also in Fig. I, where 15 is the reference number of the tubular fabric formed inside while 17 is that of the tubular fabric formed outside, each of them being formed with the needles 13 or 15 of one of the needle bars. C indicates zones to connect the two ele-ments 15 and 17 separated by the cut T.
In the formation of the body of the product the connecting zone Cc is made, typically, by processing simultaneously with a group of needles II and with a group of needles 13 structures of fabric with ribbed stitching, whereby needles II and needles 13 are ~ lt~
activated at the same time in correspondence with one feed or several or, better still, all the feeds Al, A2, A3, A4. A lay-out of this klnd is given in Figs. 9, 10 and 11, 12, which show two moments in the formation of the connecting zones of fabric Cc respectively in front of the feed Al and feed A2 o a cylinder-and-plate complex with needles.
Figs. 9 and 10 show the momentary condition in which the needles pass before the feed Al which are pre-set to form the zone Cc; therefore, at that moment not all the needles II are raised, nor are all the needles 13 kept inside, but rather in front of said feed Al (which usually serves for the formation of the product with the needles II), out of all the needles II, only those indicated with IIA (two pairs in the table) are raised, while the needles marked IIB and also the two middle needles IIC are kept low; furthermore, in that situation the needles 13 of the plate indicated with 13A, which correspond with the unraised needles IIs, are also withdrawn; before the feeds A2 and A4 only the needles 13 come out (to form the fabric 15), while in front of the feed A3 only the needles II come out (to form the fabric 17).
Let us now consider the moment shown in Figs. II
and 12 and observe that only the needles II work with the feeds AI and A3, while only the needles 13 work with the feed A~.
In front of the feed A2 there pass the needles pre-set for formation of the zone Cc, namely the needles IIA, IIB, IIC, and 13A, which are once more selected, as already said wi-th regard to Figs. 9 and 10, for the feed AI in such a way as to form the con-necting zone Cc of fabric.
When the needles pre-set to form the connecting zone Cc pass before the feeds A3 and A4, the conditions are repeated which are shown for the feed AI in Figs. 9 and 10 and for the feed A2 in Figs. II and 12.
Figs. 7 and ~ show the lay-out and methods of working to fulfil the invention in the case of a machi-ne with two opposecl cylinders. AII,A12, A13 and A14 indicate the four feeds exemplified tbut the lay-out may have any other number of feeds greater than one), whereas GII,~2, G13 and G14 are the respective thread guides.The needles 31 of the lower cylinder work with the feeds A11 and A13 to ~orm the fabric 17, whereas the needles 33 of the upper cylinder work with the feeds A12 and A14 to form the fabric 15. In the conn~cting zone Cc the needles of the two cylinders are driven in front of all the feeds so as to make the lower needles 31A take the thread, the needles 31B and also the needle or needles 31C being kept low, and to make the upper needles 33A (corresponding with the needles 31B) take the thread, the needles 33B and also the needle or needles 33C being prevented from protruding and being : . ~
L
kept within the upper cylinder. In FigO 7 the zone Cc passes before the feed ~11, while in Fig. 8 it passes before the feed ~12; this function is also repeated in front of the other feeds A13, A14.
For the drive of the group of needles 31-33 pre-set to form the zone Cc, butts can be envi-saged which have a special height or particular levels on the needles or needle jacks in the channels of said needles, or else other dispositions ma~ be made for the purpose which are well known to experts in this field.
It seems to be enough to process the connecting zone Cc with the two feeds Al and A3 (or All and A13) alone.
In this way a structure Oe fabric, as shown with Cc in Fig. 3, is obtained, the coùrses of which in that zone comprise alternately plain stitches MD and purl stitches MR, namely with a structure of ribbed stitching; in this way, beginniny from the peripheral zones indicated with E, stitches are formed with the threads of one produot 15 together with stitches of threads forming the other product 17. In a central zone marked F (and formed through the lack of activity of the needles llC and 31C, 33C) there can be an absence of stitches as none of the needles (llC and the corres~
ponding 13C) is driven to take the thread and form the stitch.
The cut indicated with the arrows T is made in this central zone F; said cut can be performed in any suitable way, for instance with heat applied by a resistance that melts the yarn, or with cutting devices with blades activated in a -timely manner, or with elements sliding in the needle seatings and equipped with a blade or other cuttiny edge caused to operate when said element is raised, the solution being analogous to that of the needles. Thus, the cut can he carried out directly on the machine, whereby the p~o-duct reaches the situation shown in Fig. 4 with one of the tubes 17-15 inserted in the other, for in that condition they are seen as they are formed by the two needle beds or needle bars II and 13.
Having been separated, the product is then spread apart, with the fabric 15 bent ou-twards from the fabric 17 and turned over, as shown in Fig. 5, so as to reach the situation of Fig. 6, wherein the connecting zones C, like the so-called "runs" at the end of working, are inside the product. In the zones C there is a steadfas-t union of the product along the line of the crutchr as is shown in Fig. 6 where it can be seen clearly that the parts C form the connection between the two fabrics of the sides of the body of the product. The fabric in the zones C conslsts, as said earlier, of ribbed stitching and of yarns belonging ~5 alternately ko one or the other of the tubular fabrics 15 and 17.For the most part the number of courses in the zones C is twice as many as the number of courses .'7~l~f~
in each of the fabrics 15 and 17 within the same unit of length; this ensures a very effective connecting structure. From an aesthetic point of view the product takes on an appearance better than that obtained with products envisaged hitherto in previous solutions.
It is to be understood that the figures show only one example, which is given as a practical demonstration of the invention, but the invention can be varied as regards forms and lay~outs without depart-ing thereby from the scope of the concept which inspires the invention itself. Obviously there is no limit to the length of the connecting zones or, therefore, to - -the vertical development of the body of the product.
It should be noted that, as said earlier, the connections can be made with all the feeds or with a reduced number of feeds. If we consider the case of four feeds Al-A2~A3-A4, the use of all these feeds -to make the connection enables the cross-wise stresses to ~ be reduced, as the connecting zone will thus have a number of courses twice as great as the number of courses in the neighbouring fabrics; a connection made with only two feeds is performed with the same number of courses as that of the neighbouring fabrics and permits a given mechanical simpliication.

According to the details shown in the attached figures, the formation of a double tubular fabric is envisaged as ta]cing place by means of two sets of nee-dles on two needle bars.
Figs.9 to 12 inclusive show a lay-out wherein are visualized a needle bar or bed of needles in a cy-linder and a bar or bed of radial needle hooks 13 in a plate or disk combined with the cylinder. AI, A2, A3 and A4 indicate four positions of yarn feed with thread guides GI, G2, G3 and G~. When the needles II take the thread, they form plain stitches, whereas when the needles 13 take the thread, they form purl stitches.
Normally, so as to form two semi-finished tubular pro-ducts 15 and 17 at the same time with continuous mo-tion, the needles 13 take the thread in correspondence with the feeds ~2 and A4, whereas the needles II take the thread in correspondence with the feeds AI and A3;
the two tubular elements having the reference numbers 15 and 17 respecti~ely are thus formed progressiveiy at one and the same time.
To form the body portion of the product (at the beginning or end of formatlon of the whole product) it is necessary to make a connection between the two fa-brics and a cut along a tract of the lengthwise develop-ment of the two tubes of fabric, as indicated with T
in Fig. ~ and also in Fig. I, where 15 is the reference number of the tubular fabric formed inside while 17 is that of the tubular fabric formed outside, each of them being formed with the needles 13 or 15 of one of the needle bars.

Let us now consider the moment shown in Figs. II
and 12 and observe that only the needles II work with the feeds AI and A3, while only the needles 13 work with the feed A~.
In front of the feed A2 there pass the needles pre-set for formation of the zone Cc, namely the needles IIA, IIB, IIC, and 13A, which are once more selected, as already said wi-th regard to Figs. 9 and 10, for the feed AI in such a way as to form the con-necting zone Cc of fabric.
When the needles pre-set to form the connecting zone Cc pass before the feeds A3 and A4, the conditions are repeated which are shown for the feed AI in Figs. 9 and 10 and for the feed A2 in Figs. II and 12.
Figs. 7 and ~ show the lay-out and methods of working to fulfil the invention in the case of a machi-ne with two opposecl cylinders. AII,A12, A13 and A14 indicate the four feeds exemplified tbut the lay-out may have any other number of feeds greater than one), whereas GII,~2, G13 and G14 are the respective thread guides.The needles 31 of the lower cylinder work with the feeds A11 and A13 to ~orm the fabric 17, whereas the needles 33 of the upper cylinder work with the feeds A12 and A14 to form the fabric 15.
