nited States Patent O 2,881,603 KNITTING MACHINE AND METHOD F KNITTING Frank John Vendetti, Philadelphia, Pa., assignor, by mesne assignments, to Scott & Williams, Inc., Laconia, N.H., a corporation of Massachusetts Application April 26, 1954, Serial No. 425,505 13 Claims. (Cl. 66-9) The present invention relates to the art of knitting and more particularly to novel plain or jersey fabric and to the machine and method of making the same.

It is an object of the invention to provide continuous draw-thread connected separable tubular jersey knit fab; ric sections each of which has a selvage formed of elastic and of nonelastic yarns, an adjoining simulated or mock rib border or cuif portion formed of elastic and of non; elastic yarns, a following body portion formed of nonelastic yarn, and a terminal run-resisting portion of non-A elastic yarn, in which the fabric sections are connected during the knitting thereof by a removeable draw-thread course of non-elastic yarn placed between the nal course of the run-resisting portion and the selvage.

It is also an object to provide a machine and a method of operating the machine to produce the novel fabric sections.

It is a further object to provide the fabric sections with non-curling edges. In the stitch construction of one such selvage a single elastic yarn is incorporated with the nonelastic yarn while in another stitch construction a pair of elastic yarns are incorporated with the non-elastic yarn.

It is still a further object to provide the'fabric sections with border portions the fabric yof which simulates the appearance of true rib fabric. In the stitch construction of one such border portion the fabric simulates the appearance of true two and two rib fabric while in other stitch constructions the fabric simulates the appearance of true two and one rib fabric. The stitch constructions are such that the border portions, by the aplgiropriate use of differently colored yarns, may be provided with walewise extending stripes.

It is an additional object to produce the fabric of this invention automatically upon a multiple feed sinker top" machine in which theA 'character of the knitting at certain of the individual feeds is adapted to be changedin accordance with the stitch requirements of the several por tions of the fabric so that successive fabric courses are formed of the individual yarns fed to the needles at successive feeds of the machine. Furthermore, so that with the same needle selection, as made by the inclined wheels of each feed of such a machine, the various portions of the fabric sections may be made even though the individual stitch constructions of these portions differ from each other.

Additional objects and advantages of the invention will be apparent from the following description thereof which should be read in connection with the accompanying drawings.

In the drawings:

Figure 19 is a schematic View of a 32 feed circular knitting machine showing the character of the knitting and the changes thereof at each of the feeds. y

The novel draw-thread connected fabric sections of the present invention may be made upon any type of jersey knitting machine, preferably having a multiple number of knitting stations or feeds, in which the needles may be selectively arranged for each of the special stitch constructions' forming a part of the fabric, and in which the feeding of the elastic and the non-elastic yarns r'nay be selectively controlled in conjunction with the needle selections. Generally such a machine, which may have either a stationary or a rotary cylinder, will have a needle cylinder 20 upon the needles of which the fabric will be knitted and will have rotating take-up rolls 21 adapted to advance and to tension the fabric as it is being triade, Figure 1`. It will be understood that the showing of Figure l is schematic only and is intended to show the general arrangement of parts in which the novel fabric is under tension during its construction.

The needle cylinder 20 and Ythe rolls 21 are preferably' part of a machine in which the needles and the yarns are adapted to be selectively controlled at'` each feed of a multiple feed circular sinker top knitting machine. The' invention is not' limited to -the product of a circular inachine nor' to a multiple feed machine and may bie made' upon any jersey knitting rn'achine of any number of fds in whichthe stitch constructions and the yarns ofecen course of knitting may be lvaried in accordance with the requirement of the fabric. Regardles'srofth'e machine used, the resultant draw-thread connected sections of fabric are illustrated in Figure 2 wherein each section 22 comprises a beginning selvage edgeI- course 23, an adjoining mock rieb border portion 24, a following'jersy body portion 25, a terminal rnnfesisting portion 26, and a dr'awlthread'course 27 c'onnectingvtlie/inal course of the portion 26 of one section 22 with the sclvage edge 23 of an adjoining section. It will be understood that' the draw-threads 27 may be'pulled, after cutting` at one or' rnore places, from the fabric to separate the sections 22 from each other. The separated sections may then be used in any desired manner in garment or other mnufact-ure. The walewisel length of the body portions 25 and of the border portions 24 may vary without' depart- A part or. the fabric, enclosed by thcdotted lines of Figure 2, is shown in enlarged detail in Figure 3' wherein the stitch construction of the several parts of one of the sections 22 may clearly be l needle for'r'ne'd stitch wales through 4 8, the jersey body fabric is shown in the

course

36 and 37 as being'plain knit without a design therein- It will be understood' that the body portion ZSVniay be unad'orn'ed or may be formed' with` any desired type of knittedy pattern or desi-gn therein, land inlay be foi-'ined of 2'8 through 35 and courses 36 seen. In Figure 3, containinga single yarn (changeable for striping) if a single feed machine is used or may be formed of a plurality of yarns (also changeable for striping) in multiple course spirals when a multiple feed machine is used to make the sections 22.k This use of single or of multiple yarns, depending upon the number of feeds, is also applicable to other parts of the fabric without further specific reference thereto. A knitting station having 'feed B set up to make plain jersey fabric is shown in Figure 7 wherein all the latch needles N are raised from a welt level W to a cast off or latch clearing level CO and are then retracted to a knitting level K Where stitches are formed of a nonelastic yarn Y fed to al1 the needles, after which the needles N are returned to welt level W, in a manner well known in the art, and one or more such feeds B may be used to make the body portion 25. The needle level indicated as CO in the drawings is intended to be that level at which yarn, in any form in the needle hook or on its latch, passes olf the end of the opened latch of the needle onto its shank as the needle is raised, this level also being known as the latch clearing level.

The run-resisting portion 26 of the fabric is shown in the courses 38 through 41 in which the

courses

38 and 40 are formed on all the needles at a feed or feeds set up like feed B of Figure 7 and in which the

courses

39 and 41 are formed on certain of the needles N at a feed or feeds set up like feed A of Figure 6. At each feed A every third needle N remains at welt level W while the intervening pairs of the needles are raised to cast olf level CO so that as the raised needles are retracted to knitting level K they form stitches of non-elastic yarn Y which oats to the rear of the non-raised needles. In Figure 6 a design wheel of usual inclined construction is indicated at 49 as the means by which the needles may be selectively raised but it will be understood that any type of needle selecting means may be used, depending upon the type of machine. A movable stitch cam of usual construction is shown at 50 to retract the needles to knitting level and the'upward position of the stitch cam is shown in dotted lines at 51 in which position the needles are retracted to welt level W as may be required for other courses of knitting.` While the other illustrated feeds do not show the design wheel 49 and the stitch cam 50, it will be lunderstoodthat they may be used at such feeds to selectively advance and to retract the advanced needles. The oats of yarn Y, in 'back of the non-raised needles at feed A, are shown in Figure Ell at 52 in

wales

28, 31, and 34 of the courses 39 and 41fwhere they are at the rear of the fabric behind vstitches formed on these same needles in

courses

38 and 40 at feed B, which latter stitches were held on the non-raised needles at feed A. While two courses having the tloats 52 have been shown, it will be understood that the run-resisting portion 26 may contain a greater number of such courses if desired and that the yarns may betucked instead of being oated, by having the non-raised needles raised to tuck level T at the feed A, for a modified form of run-resistant stitch formation. Generally the number of plain and of float-containing courses may vary depending upon the number of feeds on the machine and depending upon the number of courses needed to prevent running back of the cast olf stitches of the cast off course for any particular fabric.

A cast off course is preferably formed in the fabric following the course l41 and this consists of casting off the stitches from certain of the needles while holding the stitches on the other needles. In the present instance this is done by casting off the stitches in those wales in which the oats were not formed, namely the

wales

29, 30, 32, 33, and 35, the cast oif stitches being those which were formed by the raised needles at the last feed A and the casting off is preferably done at a feed set up similarly to feed A (and designated vfeed A-1 in Figure 19) but at which no yarn is fed. Passage of such a feed A-1 will leave the fabric suspended on every third needle of the machine by the stitches in wales 2.8, 31, vand 34 of course (in the hook) the same third needles (along with thel 41 while the intervening pairs of cast off stitches will be free of the'needles and of following fabric courses as indicated at 54, these stitches 54 being free to run back to a certain extent to the run-resistant portion 26 which acts to prevent the running back of the stitches from continuing throughout the body 25.

The draw-thread 27 connecting adjacent sections 22 is next knitted and this comprises the course 42 which is formed at a feed set up like feed C of Figure 8 wherein every third needle (the ones which have the stitches of course 41 thereon) is advanced to cast off level CO and retracted to knit stitches of a non-elastic yarn Y (which may be stronger than the regular body yarn) while the intervening pairs of bare needles (cleared of stitches at feed A-l) remain at welt level W so that the yarn is floated past them. This results in stitches in every

third Wale

28, 31, and 34 in course 42 with floats of yarn 55 therebetween and the length of yarn used for course 42 is thus shorter than it would have Ibeen if stitches were formed on all the needles of the machine. The thus shortened draw-thread is easier to remove from the fabric than a yarn which has been knitted in every wale.

While the cast off course has been shown as having. the spaced pairs of cast off stitches, it should be understood that the number and the spacing of the cast otf stitches may vary and that the draw-thread will be knitted through the non-cast olf stitches to connect the sections 22. It should also be understood that the fabric may be made without a cast ot course, if so desired, in which event the run-resistant portions may be eliminated and that in this instance the draw-thread, knitted through all of the stitches of the final course of the body portion, will be undesirably long.

Once the draw-thread has been formed, the selvage edge 23 of a succeeding

section

2,2 may be started, and in the form shown in Figure 3, this comprises a pair of

elastic yarns

56 and 57 incorporated with the nonelastic yarn of the fabric. For this purpose the needles next pass through a feed set up as feed D of Figure 9 wherein every third needle (one of each pair of bare needles) is advanced from the welt level W to the tuck level T and is then retracted -to the welt level to take the relatively heavier elastic yarn 56 in the hooks thereof while the intervening pairs of needles remain at the welt level so that the elastic yarn 56 is floated to their rear, the interlacing of the elastic yarns being shown in Figure 18. At feed D the stitch cam will have been raised to dotted line position 51, as shown in Figure 6, to retract the needles to welt level only and the elastic yarn will be retained in position around the needles by the hooks of the usual sinkers. Then the needles are caused to pass through a feed set up as feed E of Figure l0 whereinf the spaced pairs of bare needles (bare of non-elastic yarn since being cast oif at feed A-l), one of each pair of whichhas the elastic yarn 56 in its hook, are advanced from welt level W to tuck level T and are then retracted to the welt level to take the lighter elastic yarn 57 in the hooks thereof while the intervening single needles (having stitches of the draw-thread thereon) remain at the welt level so that the elastic yarn 57 is floated to the rear thereof.y It will be understood that the stitch cam at feed E is in raised position 51 and that the elastic yarn 57 is also retained in tucked position on the needles by the sinker hooks. As shown in Figure 18, the elasticl yarny 56 will be in front of (in the hook) every third needle (bare) and to the rear of the intervening pairs of needles while the elastic yarn 57 will be in front of elasticlyarn 56) and the bare needles adjacentl thereto while being in back of the remaining needles (along with the elastic yarn 56) which have the draw-thread stitches thereon. The needles, with the elastic yarns so inter-v laced, are then vcaused to pass through a feed such as feed B wherein all the needles are advanced to castoff level from which they are retracted to knitting level K 'after having been fed the non-elastic yarn Y, the resulting course being shown at 43 in Figure 3 wherein loops of the non-elastic yarn are drawn through the draw-thread stitches in wales 28, .31, and 34, and wherein the elastic yarns 56 and 57 (which dropped below the needle latches as the needles were raised at this feed B) are cast olf to be interlaced in the sinker wales of the rst row of loops of a section 22. More specifically, the yarn of course 43 in the sinker wale between needle formed 4wales 28 and 29 (and in corresponding sinker wales) extends over both

elastic yarns

56 and 57, while in the sinker wale between needle formed wales 29 and 30 (and in corresponding sinker wales) the yarn extends between the elastic yarns and over only the elastic yarn 56, and while in the sinker wale between the needle formed wales 30 and 31 (and in corresponding sinker wales) the yarn extends between the elastic yarns and over only the elastic yarn 57, to form the selvage edge 23 of the fabric section 22. In this way there is a separate starting loop for each Wale of the new section of fabric and the elastic yarns form a part of the selvage edge and keep the same from ravelling. While elastic yarns of different diameters are shown, which were fed under a certain amount of tension, the larger elastic yarn aids in keeping the edge in at non-curled condition but it will be understood that both elastic yarns may be of the same size. lt should be noted that the draw-thread of course 42 may be removed and will leave a selvage edge in which the non-elastic yarn of every one of the sinker wales of the course 43 will be interlaced with one or the other or both of the elastic yarns.

After the selvage edge, the border portion 24 may be made and this commences with the course 44 which is made by causing the needles to next pass through a feed set up as feed B of Figure 7 which will knit a plainjersey course of non-elastic yarn. Thereafter each of the courses 45 through 48 (and as many more as may be required for a desired length of mock rib border) is made of a pair of non-elastic yearns, designated 58 and 59, and of an elastic yarn, which may be like the elastic yarn 57, by causing the needles to pass through three feeds for each course. Considering the course 45, the first feed following the course 44 is set up as feed E of Figure l0 at which an elastic yarn 57 is fed to the same spaced pairs of tuck level needles, the feed E operating in the manner previously described. Then the needles are caused to pass through a feed set up like feed F ofFigure l1 in which spaced pairs of needles (spaced by a single needle), of the wales 29 and 30 and of corresponding wales, knit the non-elastic yarn 58 of this feed and in which the intervening single needles tuck this yarn. It should be noted that the needles knitting at feed F had the elastic yarn on them in tuck position from feed E, so that as these needles are knitted, they cast olf the tucked elastic yarn 57 along with the stitches of course 44, this, cast olf portion of the elastic yarn 57 being shown at 60. The tucked portion of the yarn 58, fed at feed F to the intervening needles, is shown at 61 along with the stitches of course 44. The needles are then caused to pass through a feed set up as feed G of Figure l2 in which the action is the reverse of feed F, namely where in feed F there were two needles knitting and one tucking, there are now two needles tucking and one knitting, and this causes the single needles, of the wale 31 and corresponding wales, to knit non-elastic yarn 59 and at the same time cast off stitches of course 44 and the tucks 61 of yarn 58, while the pair of tucking needles take the yarn 59 in position at tuck level, the tucked portion thereof being indicated at 62. The needles are then caused to pass through a repeat of the three feeds E, F, and G for each course of the border 24. It should be noted that starting with the course 46, the pairs of needles knitting at the feeds F will have tucks 60 of the elastic yarn as well as tucks 62 of the non-elastic yarn 59 to cast off as the yarn 58 is knitted.

While the elastic yarn of the border portion 24 has been shown as incorporated unknit with the non-elastic yarns, it should 'be understood that the elastic yarn may be incorporated in other ways, as by knitting stitches thereof, in the border portion within the general concept of the invention as it relates to a series of connected individual fabric sections. Furthermore it should Vbe noted that portions of mock rib fabric, in addition to being adjacent the selvage edge, may be placed within the body portion 25 of the fabric sections 22 for ornamental or for other purposes.

Once the border 24 has been made of suflicient length, the needles are caused to pass through feeds set up as feed B for jersey knitting of non-elastic yarn for the body 25 until it is time to start the run-resistant courses at which time the above set forth method of knitting will be repeated to form the next following section 22.

Attention is directed to the fact that, starting with the course 45, only the yarn 59 appears in every third Wale of the border 24 while only the yarn 58 appears in the intervening pairs of wales, so that vertical stripes may be made in the border by having these yarns of different colors or of other different characteristics and that the single Wale color will be at least partially hidden from view until the border 24 is stretched. Every third wale, of the yarn 59, is forced to the rear of the fabric by the elastic yarn 57 to a relatively submerged position, while at the same time the elastic yarn forces the intervening spaced pairs of wales, of the yarn 58, upwardly from the face of the fabric to give a rib-like appearance to the border and in this instance the appearance is that of a two and one rib fabric. It will be noted that the elastic yarns are preferably fed to the needles under a certain amount of controlled tension and that the diameter of the border portion 24 in comparison to the diameter of the knitted tube body portion 25 will depend, for a given diameter of elastic yarn, upon the amount of such tension and upon the special vstitch construction of the present border portion. lt is preferred that the elastic yarns be fed under relatively light tension so that the border portion will not-be reduced too greatly in diameter in comparison to the body portion 25 and to this end the stitch construction is of substantial aid, for it has been found that the present arrangement of the non-elastic yarns (which widen out and thicken the fabric) make it possible to use such light tension on the elastic yarns -and pro-l vide a sufficiently expandable mock rib border portion of satisfactory diameter, feel, and thickness insofar as the rib-like characteristics thereof are concerned.

While the present fabric may be made upon many types of machines, it is preferably made upon a multiple feed sinker top machine having chain positioned means adapted to selectively control the yarns, the needles, the nullifying cams, and the stitch cams at each of its feeds. In Figure 19 the knitting vaction of each feed of a thirty two feed sinker top machine (preferably having a rotary cylinder) is illustrated as the machine is set up to make the fabric sections of Figure 2. Assuming that the body portion 25 of a section 22 is being knit, then all thirty two feeds will be arranged by the chain controlled means to be set up as feeds similar to feed B of Figure 7 so that thirty two courses of plain fabric will be knit upon each rotation of the needle cylinder. When the body 25 is finished and the run-resistant portion 26 is to be made, the chain positioned means will be set to change the feed set ups of certain of the feeds, and, starting with feed 1, this feed will be permitted to remain set up as a feed B to make course 38; the feed 2 will be changed so as to be set up as a feed similar to feed A of Figure 6 t0 make course 39; the feed 3 will remain set up as a feed B to make course 40; the feed 4 will remain set up as a feed B to make a plain course similar to the course 40 (so that there will be two plain courses 40 between

courses

39 and 41 of Figure 3); the feed 5 will be set up as a feed similar to feed A to make course 41; the feeds 6 and. 7 will remain'set up as feeds B to make plain courses similar to the course 40 (so that there will be two plain courses between courses 41v and 42); the feed 8 will be set up as a feed similar to feed A with the yarn withdrawn (designated feed A-l) to cast olf the stitches of course 41; the feed 9 will be set up as a feed similar to feed C of Figure 8 to make course 42; the feed 10 willbe set up as a feed similar to feed D to feed elastic yarn 56 for the selvage edge; the feed 11 will beset up as a feed similar to fe'ed E to-feed elastic yarn 57 for the selvage edge; the feed 12 will remain set up as a feed B to make course 43; the feed 13 will remain set up as a feed B to make course 44; the feeds 14, 15, and 16 will be set up as feeds similar to feeds E, F, and G, respectively, to form course 45;.the feeds 17 through 31 Will be set up as five adjacent series of three feeds each, in which each series of three feeds will be set up as feeds similar to feeds E, F, and G, respectively, to consecutively form the courses 46, 47, and 48y (and following like courses); and the feed 32 will be thrown out of action by causing the needles to pass by at welt or at tuck level, by withdrawing the yarn, and by raising the stitch cam to level 51. This completes a round of the machine and as the next round starts, the feeds 1 through 9 will be set up as three adjacent series of three feeds each, in which each series of three feeds will be set up as feeds similar to feeds E, F, and G, respectively, to form additional courses of the border 24; the feed 10 will be thrown out of action simply by withdrawing the elastic yarn 56; the feed 11 will remain set up as a feed E; and the feeds 12 andv 13 will be set up as feeds similar to feeds F and G, respectively, so that feeds 11, 12, and 13 will act to form a course of the border portion. It will be noted that al1 of the machine feeds (except feeds and 32 which are out of action) are now set up as continuing series of three feeds E, F, and G, and the machine is permitted to operate with this feed set up until a complete border portion 24 has been knitted. When it is desired to discontinue knitting the border and to start the body 25 knitting, the chain means will again start with feed 1 and will change the feed set ups at each of the thirty two feeds (including the feeds 10 vand 32 which may be used for the body) so that each feed isset up as a feed B for plain knitting the' body 25.

The reason for throwing out feeds 10 and 32 is to provide a multiple of three feeds in action for the mock rib knitting since each course thereof requires the use of three feeds. It should'be noted that each feed which is set .up as a feed E has its feeding yarn changed from non-elastic to elastic yarn for so long as it remains so set up after which the yarns are again changed so that non-elastic yarns are fed .to the needles. It should also be noted that the machine isl supplied with one or more of the usual latch openers following feed 8 (at which the cast off .is made) so that the bare needles will have opened latches at the feeds next placing yarn on the bare needles. The run-resistant portion of the fabric as made upon the machine set up of Figure 19 differs slightly from the fabric as shown in Figure 3 in that certain extra plain courses (made on feeds 4, 6, and 7) were added, however this does not detract from the effectiveness of the run-resisting action. In the present instance these courses were added because it was more convenient to set up the machine this way for the most effective use of its feeds. Attention is directed to the fact that at each feed where a needle selection is required, its wheel 49 is set up for the particular two and one (-or one and two) needle selection and for the proper' needle-level separationj required at that feed so that when the nullifying cam of each feed (between its wheel and its stitch cam) is in lowermost position, each feed will provide the needle level separation of its wheel selection; when each nullifying cam is in fits intermediate position each feed will still provide the same needle selection but those needles which previously were at welt level will now be at tuck level; and when each nullifying cam is in its uppermost posi` wherein all the needles the tucked portions of the elastic yarn 93 are cast off in tion it will raise all the needles so that each feed will act4 as a plain feed similar to feed B. Thus with the same basic wheel selection at each feed along with the appropriate use of the nullifying cams, it is possible to provide knitting stitches at a feed (or when making the cast offl course) and is moved to upper level 51 when no stitch loops are formed.

A modification of the fabric is illustrated in Figure 4 in which certain portions of the fabric sections are of a' different stitch construction. In Figure 4 the body portion of a modified form of a section 22 is shown at 63, the run-resisting portion is shown at 64, the draw thread is shown at 65, the selvage edge is shown at 66 and the mock rib border portion is shown at 67, the fabric illustrated having the needle formed stitch wales 68 through and the courses 76 through 90. The

courses

76 and 77 are formed on feeds set up as feed B whichl provides plain jersey body courses. The

courses

78, 80, and 82 are also formed on feeds set up as feed B, however, in courses 78 and S0 the 70 and 71 and in the Wales 74 and 75 are held while the

courses

79 and 81 are formed on feeds set up as feed H of Figure 13. The difference of portion 64 of Figure 4 over the portion 26 of Figure 3 is that in the former the needle set up is two and two whereas in the latter it is two and one. Following plain course 82 the needles are caused to pass through a feed set up as feed H with? out yarn thereat so that spaced pairs of loops are cast off as shown at 91. The needles are then caused to pass through a feed set up as feed I of Figure 14 wherein the spaced pairs of bare needles (made bare by the cast oif course) remain at the welt level missing the nonaelasticV yarn while the intervening pairs lof needles are raised to cast off level and are retracted to knitting level to knit` stitches of the yarn Y, thus forming the draw-thread course 83. The needles (some of which are bare) are then caused to pass through a feed set up as feed I of Figure l5 wherein alternate needles remain at Welt level while the intervening needles are raised to tuck level to take the elastic yarn 92 in their hooks (retaining the draw-thread course stitches) and are then retracted to welt level, the elastic yarn passing to the rear of the welt positioned needles. This causes the elastic yarn 92 to be interlaced in front of and in back of every other needle. plain feed set up as feed B wherein all the needles take non-elastic yarn Y and when they are retracted to knittingv level the needles will cast olf the tucks of the'elastic yarn (along with the stitches of the draw-thread course on some of the needles) so that the elastic yarn will be f interlaced with the non-elastic yarn of each sinker Wale to form the selvage edge 66 at the same time that the course 84 is formed. Removal of the draw-thread course will leave a selvage edge as shown in Figure 5. The needles are then caused to pass through a feed set up as feed B wherein plain course 85 is formed. Then the needles pass through a feed set up as feed L of Figure 16 wherein spaced pairs of needles (of Wales 72 and 73 and corresponding wales) remain at the welt level and wherein the intervening pairs of needles take the elastic yarn 93 at tuck level and are retracted to Welt level to place the elastic yarn in back of the non-raised needles. The elastic yarn 93 may he of smaller diameter than the elastic yarn 92 used for the selvage edge. The needles are then caused to pass through a feed set up as feed B knit a non-elastic yarn 94 while pairs lof spaced stitches in the wales The needles are then caused to pass through acourse 86. Then the needles pass through a feed set up as feed 'M of Figure 17 wherein spaced pairs of needles (of wales 74 and 75 and of corresponding wales) knit the yarn 95 to form course 87 in which the yarn 95 4is tucked on the intervening pairs of needles 'as yshown at 96. The needles then pass through succeeding series of three feeds each, in veach series of feeds there is fed in succession an elastic yarn 93, a non-elastic yarn y94 and a non-elastic yarn 95 to form the following courses of the mock rib border portion. It will be noted that y'in the modification of Figure 4 the border simulates a two and .two rib fabric and that there are twice `as many stitches in the raised wales 70 and 71 and corresponding wales than there are in the submerged intervening wales 72 and '73 and corresponding Wales. rThe extra number of stitches inthe raised wales increases the mock rib effect as it makes these Wales thicker than the adjoining wales of ,a lesser number of stitches. The border may have a walewise striped effect by having Vthe yarns 94 and 9S of different colors for the yarn '94 is the -only one forming stitches in the submerged wales while the yarn 95 forms larger stitches which substantially hide the smaller stitches of the yarn 94 in the raised "wales, the action of the elastic yarn and of the Atwo-.course held stitches contributing to the smaller stitches.

The sections 22, with the modifications of Figure .4 .or with the modifications to be described in connection with Figure 5, may be made upon a multiple feed .sinker top machine after the general method outlined in :connection with the fabric of Figure 3 with the inclined `wheels arranged to make the necessary needle selections.

Another modification of the mock rib border portion is shown in Figure wherein 97 designates the selvage edge which is similar to the selvage edge 66 of Figure `4. Itis obvious that the selvage of Figure 3 could be used with fabric modification of Figures 4 or 5 in place of the single elastic yarn selvage. The border portion is shown at 98 and the stitches. thereof are in wales 99 through 106 in the courses 107 through 111, the course 107 forming the selvage edge along with the elastic yarn. Course 108 is a plain course formed by having the needles pass through a plain feed set up as feed B. In making the border, the needles then pass through fa feed set up as feed E wherein an elastic yarn 112 is `interlaced about the needles, being tucked in the wales 103 and 10.4 and in corresponding wales. This elastic yarn passes to the rear of the intervening single needles `which form the intervening wales. The needles then pass through a feed set up as feed F in which the needles forming the pair of adjacent wales 103 and 104 (and corresponding spaced pairs of wales) upon which the elastic was tucked upon preceding feed E, knit a non-elastic yarn while the intervening single needles (of wale 102 and corresponding wales) pass by at a tuck level so that this yarn is ltucked in these single wales as shown at 113. At this feed F, as the spaced pairs of needles knit the vnon-elastic yarn, they will cast off the tucked elastic yarn thereon. Then the needles pass through .a feed set up as feed C wherein the single intervening needles knit a secondnon-elastic yarn while said spaced pairs of needles remain at welt level so that this second non-elastic yarn is floated to the rear of the fabric as shown at 114, the ysingle needles casting off the tucks of the rst non-elastic yarn at the same time. The 'last three described feeds are used to make the course 109 and the succeeding courses 110 kand 111 are each formed of a like series of three feeds. Here again the border may have walewise stripes since separate yarns only are knitted in the raised pairs of spaced wales, 103 and 104 and the like, and in the intervening submerged spaced single wales, 102 and the like. The mock rib effect of the Figure 5 fabric causes the border 98 to simulate a two and one rib fabric somewhat similar to the border portion fabric of Figure 3. It will be under- =stood that the border of Figure 5 may forma part of a complete section 22, of a series of draw-thread coli` neeted fabric sections.

My invention is not limited to the specific details and formation of stitches herein shown, and vdescribed in the embodiments selected for purposes of illustration, v-as variations may be made in the series of connected fabric sections and in the machine and method of making lthe' same, and within the scope of the following claims.

While the mock rib jersey fabric has been shown `as for-mingthe border portions of fabric sections of relatively largefdiameter, it is of general use as a mock rib `fabric in theknitting art and as an example thereof it may be made of smaller diameter as when made von a hosiery machine of one or more feeds, and may be used (along with a suitable elastic yarn selvage edge course) `as `an integrally formed mock rib top portion for hosiery, within the scope of the appended claims.
